Emulsion fuel offers environmental benefits

 

Environmental technology company Nano Bubble Technologies (NBT) says its emulsion fuels offer the boiler industry environmental and economic benefits.

 

NBT points out that a feature common to emulsion fuels is that they can be used with minimal service and maintenance requirements in boiler plants.

 

The company offers stable and cost-effec-tive fuel emulsions. The production of these emulsions involves the use of chemical additives, a mechanical blending process and technical know-how, ensuring that the emul- sions are stable throughout the working temperature and pressure range. The benefits of using emulsified fuels are derived only if the emulsified fuel remains stable immediately prior to combustion. NBT’s technologies reli- ably produce stable emulsified fuels of consis-tent quality and standard, says the company.

 

“Emulsions are inherently unstable. Over time, they will separate into the stable states of the dispersed and continuous-phase materials. “To maintain the composition of an emulsion, surface-active agents, or ‘surfactants’, are incorporated into the production of an oil-phased emulsion. In an oil-phased emulsion, these surfactant agents encase the droplets of water distributed throughout the continuous oil phase and prevent the water droplets from joining and coalescing,” says NBT depot sales manager Karl Henriksen.

 

NBT’s proprietary technology creates stable mixtures of emulsified fuels, which contain varying percentages of water content. The emulsion technology can be applied to bind various base fuels with water, creating an array of environment-friendly products that reduce both oxides of nitrogen (NOx) and particulate matter (PM) pollution created during the combustion process. 


“Combustion occurs on the surface of each fuel droplet as the fuel is exposed to oxygen in the air. Larger fuel droplets do not combust completely, causing unburned fuel to escape as particulate matter in exhaust gases. This reduces overall thermal efficiency and increases harmful emissions.

 

“Unlike ordinary fuels, when emulsified fuel droplets are sprayed into the combustion chamber, a secondary atomisation occurs as a result of the violent transformation of the water droplets into steam. This transformation of water into steam shatters the petroleum surrounding the water particle into much smaller fuel droplets,” explains Henriksen.

 

NBT emulsified fuels are a blend of traditional liquid fuels such as diesel, paraffin, heavy-fuel oil or biodiesel and water. The water is present as droplets of about 2 µm, which are distributed throughout the base fuel. The emulsion is known as an oil-phase emulsion. As a result, the finished emulsion has many of the physical characteristics of its base fuel.

 

Emulsion technology better atomises fuel through the vaporisation of water, allowing for a cooler and more complete combustion. In diesel- or biodiesel-based emulsions, extremely small water particles are entrained in the base fuel through a high-shear blending process that employs an additive to bind the water and fuel in a stable emulsion. Emulsions are the only fuel that simultaneously reduces both NOx and PM emissions.

Jakarta Crown Eco Management, No environment, no economy


In the path of prosperity, modern economies devastated many of the natural resources. In the name of economic growth, industrial activity squandered ecosystems services (responsible for the maintenance of biodiversity), disfiguring nature on several fronts. Arguably, climate has been - and is being - caused by "man-economics." The goal? To make the economy grow exponentially producing in excess to meet the excessive consumption. The result? The environment threatened by excessive consumption. The result of this? Environmental depletion.

 

Unequivocally, economic output implies destruction and degradation of the environment. By itself, it is enough to guide decision-making towards the development of a new economic paradigm geared to ecological orders, not to market-led ideology.

 

If we do not change the current economic paradigm it is the very economy that increasingly plays into the abyss of destruction, as Lester Brown remembered, "the economy depends on the environment. If there is no environment, if everything is destroyed, there is no economy."

 

Regarding this line of analysis, Clovis Cavalcanti tells us that "there is no society (and economy) without an ecological system, but there can be an environment without society (and economy)." "Without recovering the environment, the economy is not saved, without recovering the economy, you don't save the environment," contextualized the U.S. ecologist Berry Commoner (1917-2012).

 

Nessa mesma linha de análise, Clóvis Cavalcanti nos diz que "não existe sociedade (e economia) sem sistema ecológico, mas pode haver meio ambiente sem sociedade (e economia)". "Sem recuperar o meio ambiente, não se salva a economia; sem recuperar a economia, não se salva o meio ambiente", contextualizou o ecologista norte-americano Berry Commoner (1917-2012).

 

While in its conventional models the traditional economy makes it a point to not include the framework or environmental constraints, because the prevailing view of the economic system as a whole extols the praises of the circular flow of wealth, imagining, therefore, an economy as an isolated system, like a human body endowed with only the circulatory system, there is no denying the enormous degree of economic dependence in relation to a finite natural ecosystem (the environment), since the fundamental nature of the economy is to extract, produce and consume.

 

The relationship of the economy (industrial activity) with the environment is intense. One cannot lose sight that the economic system is an open system that exchanges energy with the environment. In this exchange, it receives prime energy (clean) and returns it in a degraded form (dirty).

 

So, metaphorically, if the economy is a human body, the digestive tract is contemplated here, since it receives from nature and returns matter and energy in the form of waste. Reaffirming that idea, we should remember a passage from Nicholas Georgescu-Rogen (1906-94): "The economic system consumes nature - matter and energy with low entropy - and provides garbage - matter and energy high entropy - back to nature."

 

Therefore, it is of fundamental importance to subordinate the growth to the limits of the ecosystem, since growing beyond the "normal" is highly detrimental to the environment. Therefore, the new economic paradigm must converge with the ecology, since we depend on this for our own survival. The challenge is unique: produce more (welfare) with less (natural resources). Produce more quality (development), not quantity (growth).

 

Hence the maxim that we are therefore dependent on the environment, thus contradicting the speech of René Descartes (1596-1650) that "we are masters and lords of nature." For this idea of the French philosopher, the economy wasteful of natural resources, managed by "economic man-" would be acting correctly in propagating destruction, pollution and environmental degradation, since to generate wealth is generated before the destruction of nature.

 

The future of life - and especially of human life - on Earth, shall depend on the direction that we give to the economy today. If our ultimate goal is the continuity of the life of our species we should follow the prescriptions advocated by Georgescu-Rogen: "(...) one day humanity will have to reconcile development with the economic downturn." Otherwise, we will perish.

6th EHPA Forum discusses heat pump labelling: consumers willing to pay for better environmental ratings

 

Around 150 participants gathered on 15 May 2013 in Brussels, Belgium for the 6th EHPA (European Heat Pump Forum). In addition to presentations on the role of heat pumps in balancing energy demand and a debate about their continued existence without f-gases, Antonia Dickmanlooked at heat pumps from the consumer perspective asking “How interested are consumers in renewable heat and what impact can energy labelling have?”

                                                                                    

Although heat pumps are currently a niche technology in many EU countries, they are expected to form a necessary part of Europe’s low carbon future. Renewable heat policies alone however, will not be able to shift heat pumps to the mainstream. At the EHPA (European Heat Pump Forum) Forum held earlier this month, Antonia Dickman looked at the impact of energy labelling on consumer purchases, and whether these could be used to help influence the heat pump uptake.

 

To answer the question, “could labelling help consumers make more informed choices?” Antonia Dickman’s presentation looked at two key studies:

 

DECC, More Efficient Heating Study - a GB case study

DG Energy, Study into EU product label options

 

Untapped market potential for heat pumps in those that “don’t know” about renewable heating

 

The “More Efficient Heating Study” indicates that UK consumers are wedded to their gas boilers. The study survey of around 2,900 British homeowners points to gas as the default heating choice, and that most British consumers know little about renewable heating and cooling options. Although two thirds of respondents indicate that they have heard of solar thermal heating, 7 in 10 say they have never heard of ground source heat pumps.

 

The study also brought to light the large section of consumers who have “no opinion” or “don’t know”, suggesting there is a large untapped market potential for heat pumps to become seen as “fairly positive” to “very positive” by consumers.

 

How can we help inform consumers to make more environmentally friendly choices?

 

The second study presented by Ms Dickman was conducted by IPSOS Mori for DG Energy on EU Product Label Options, and looked at how consumers might be helped by labelling to make more environmentally friendly choices.

 

The online research targeted 6000 consumers to investigate the impact of adding more indicators to the energy labels of goods such as washing machines, TVs and light bulbs. Would consumers make different purchasing choices if a simple indicator displaying a good’s water consumption, carbon footprint, and/or resource use was added? How would such an indicator affect willingness to pay?

 

Results showed that consumers are more likely to choose environmentally products with the added label indicators and are also more likely to bid more.

 

Interestingly, there was no preference for either the added water, carbon footprint or resource use indicators. What was important was that the environmental impact of the product was clearly labelled. Given that environmental information has to compete with lots of other information, consumers may benefit from having easy-to understand short cuts in the form of logos that simplify the environmental rating of the product.

 

Is the current Energy Label enough to stimulate heat pump market

 

The IPSOS research begs the question is the Energy Label too complex? Would an overall environmental rating appeal more to consumers? Whilst such label may be less useful for lower cost household products, the IPSOS study indicates that for white good this might be the case.

 

The impact such environmental rating labels have on heat pump purchases however, in the end will depend on getting the information to consumer. Currently installers and developers are more often than not the intermediaries who purchase products such as heat pumps, so how can knowledge about environmental ratings be put ot best use?

 

About the EHPA

 

The European Heat Pump Association was established in 2000 to promote awareness and proper deployment of heat pump technology in the European market place. EHPA promotes heat pumps in residential, commercial and industrial applications by providing technical and economic input to European, national and local authorities.

Households to get doubled subsidies of £2,300 off green boilers to boost flagging renewable scheme

 

Households will get up to £2,300 towards installing expensive green boilers, after ministers doubled the taxpayer-funded subsidies because of poor take-up.

Only 5,000 households a year have been applying for vouchers to towards the cost of green heat systems, despite previous estimates that 25,000 people would take them up in the first nine months.

The Government yesterday admitted the green heating systems are more expensive than previously thought. The renewable heating systems are most suitable for households in rural areas that are currently off the gas grid and suffer very high energy bills. However, it can take years for householders to make their money back on the installation costs.

Greg Barker, an energy minister, said he wanted to see "even more consumers stepping up to the plate and getting on board".

“This time-limited, big increase in the value of vouchers for hardworking people who want to do something positive to install money saving green heating in their homes, should be a real boost for this growing green sector," he said.

Ground source heat pumps, which extract warmth from underground, cost more than £9,000 to install. The Government is now offering £2,300, rather than £1,350 off the installation price.

Air source heat pumps, which take heat from the atmosphere, cost more than £6,000 to put in and the subsidies will rise from £850 to £1,300.

Biomass boilers, fuelled by wood, cost around £11,500 and households will get £2,000, rather than the current £950. The cheapest technology is solar panels for heating water, which costs around £4,800 and people will get vouchers worth £600, rather than £300.

Households can get the money-off vouchers until March next year. The system was brought in after the Government delayed its new subsidy regime for "renewable heat".

When that it is introduced, it will pay households, businesses and voluntary groups for the green heat they produce. However, people will have to bear the costs of installation and maintenance themselves.

A national disaster warning: in up to five million years, this is the first time that the concentration of carbon dioxide in our atmosphere is approximately to reach 400 parts per million (ppm).  Monday on The guardian reports, former NASA scientist James Hansen warned that levels over 350ppm would destabilize the earth’s climate, but now we have far exceeded that figure with a record-breaking weekly average of 398.5ppm recorded.  While in May 2013, researchers at the Earth Systems Research Laboratory in Hawaii expect we will hit the 400ppm milestone.

 

Aside from many other issues like global fraud for example there are many else the government should give attention to. According to The Guardian, the US government has been monitoring atmospheric carbon dioxide levels at the Mauna Loa station located at an elevation of 11,115 feet since 1958.  During the time when it was first ascertained, CO2 levels stayed at a manageable 316ppm, but in the past five decades population expansion coupled with the growth of industrialized nations hooked on fossil fuels and meat has saturated the atmosphere with heat-trapping gases.

 

“I wish it weren’t true but it looks like the world is going to blow through the 400ppm level without losing a beat. At this pace we’ll hit 450ppm within a few decades,” Ralph Keeling, a geologist with the Scripps Institution of Oceanography which operates the Hawaiian observatory, told The Guardian. It is as if it was a national disaster warning.

 

This “sobering milestone” should be a wake up call for governments to support clean energy and slash emissions, said Tim Lueker, an oceanographer and carbon cycle researcher with Scripps CO2 Group.

Jakarta Crown Eco Management, Hole in the Sun


Coronal holes are areas where the Sun's corona is darker, and colder, and has lower-density plasma than average. In this case it looks like a giant hole in the middle of the sun. These were first found when X-ray telescopes in the Skylab mission were flown above the Earth's atmosphere to reveal the structure of the corona. An extensive coronal hole rotated towards Earth recently (May 28-31, 2013). The massive coronal area is one of the largest seen in a year or more. Coronal holes are the source of strong solar wind gusts that carry solar particles out to our magnetosphere and beyond. Solar wind streams take 2-3 days to travel from the Sun to Earth, and the coronal holes in which they originate are more likely to affect Earth after they have rotated more than halfway around the visible hemisphere of the Sun, which is the case here.

 

Watching the solar corona is like observing the patterns of  clouds in the sky.  They can form all sorts of shapes.  In June 2012, for example, there was a big bird image.  Snapped through three of NASA Solar Dynamics Observatory  extreme ultraviolet filters, this current coronal hole is caused by a low density region of hot plasma.

 

The Sun's corona, or extended outer layer, is a region of plasma that is heated to over a million degrees Celsius. As a result of thermal collisions, the particles within the inner corona have a range and distribution of speeds described by a Maxwellian distribution. The mean velocity of these particles is about 145 km/s, which is well below the solar escape velocity of 618 km/s. However, a few of the particles achieve energies sufficient to reach the terminal velocity of 400 km/s, which allows them to feed the solar wind. At the same temperature, electrons, due to their much smaller mass, reach escape velocity and build up an electric field that further accelerates ions - charged atoms - away from the Sun.  The corona is one of the sources of the solar wind.

 

Solar maximum or solar max is a normal period of greatest solar activity in the 11 year solar cycle of the Sun. During solar maximum, large numbers of sunspots appear and the sun's irradiance output grows by about 0.1%. The increased energy output of solar maxima can impact global climate and recent studies have shown some correlation with regional weather patterns.

At solar maximum, the Sun's magnetic field lines are the most distorted due to the magnetic field on the solar equator rotating at a slightly faster pace than at the solar poles. The solar cycle takes an average of about 11 years to go from one solar maximum to the next, with an observed variation in duration of 9 to 14 years for any given solar cycle.  The cycle is peaking now and is causing increased solar activity such as coronal holes.

Wireless Technology Improves Visibility

A move to automated measurements, via wireless technology, has offered greater process visibility for one gas storage operator which has allowed it to work much closer to capacity.
Nicole Young's insight:

Crown Capital Eco Management

 

A move to automated measurements, via wireless technology, has offered greater process visibility for one gas storage operator which has allowed it to work much closer to capacity.

                                                

RWE Gas Storage is an underground gas storage operator in the Czech Republic, operating six facilities with a total capacity of almost three billion cubic metres. Gas is stored in porous underground facilities during low-off take periods and supplied to users when demand peaks.

 

The facility has active operating reserves of 900 million cubic meters with a current maximum daily output of 15 million cubic meters and is supplied by 47 production wells via an underground pipeline. Incoming gas is filtered and metered, then compressor units generate the necessary injection pressure. After the gas cooling process, the gas is pumped through high-pressure pipes into wells connecting to the storage caverns.

 

The company is continually looking to improve the overall effectiveness of its underground gas storage facilities as measured by the maximum daily input and output. To improve the total amounts required better control, which required higher visibility into the process. However, manually reading over 100 pressure and temperature measurements took around two hours every shift. Having so many manually read gauges was a particular problem when the gas injection rate was higher. This required manual supervision along the entire pipeline, which utilised most of the operations resources. Automating these measurements would give operators greater visibility into the process and increase their efficiency, which would enable them to perform other, more important activities.

 

As well as gaining access to diagnostic data from existing control valves new online pressure, temperature and level measurements were required. Improved visibility to the process would enable operators to run the facility closer to capacity minimising downtime by detecting problems that would, otherwise, lead to unplanned maintenance. This would help to increase overall input and output at the facility.

 

Time limits

The difficulty was completing the necessary work in the limited time available. The upgrade needed to be performed in a short space of time as any planned maintenance or upgrade projects at the facility can only be performed during two short periods – about two weeks in the autumn and again in the spring – when neither injection nor withdrawal takes place. Such tasks need to be carefully planned, and even then there are limitations in terms of the size of project that can be completed within the tight timeframe. The scale of the project, including upgrades to existing valves and installation of over 100 new measurement points, would be difficult to complete in the time available.

 

To add to the difficulty of the task, there was no available existing cabling infrastructure to support the new digital measurement devices, and a lack of available I/O cards in the control host.

 

RWE investigated the possibility of installing new cabling throughout the facility to connect the new and upgraded devices, but installation could not be accomplished in the two-week window. Even if the upgrade were divided into smaller projects it was still not possible to complete within the timeframe. There was also no possibility of increasing the shutdown period. Every day the facility was not available to withdraw gas would cost RWE an estimated $250,000 in lost income. A wired solution was therefore not an option.

 

The use of wireless technology would remove the need to install new cabling, significantly reducing the overall upgrade project time, making the project more manageable and ensuring it could be completed without additional plant downtime. RWE estimated that upgrade projects using wireless take only a quarter of the time required to install wired devices.
