Seminar stresses on judicious use of petro products
Express News Service

Chandigarh, Aug 30: The Petroleum Conservation Research Association (PCRA), set-up by the Government of India, today highlighted the importance of conservation of energy and the ways and the means by which it can be conserved.

Director, PCRA (New Delhi), Leena Mehendale was addressing a press meet today. She said PCRA was into formulating the strategies and measures to promote economical use of petroleum products. It also aims at highlighting the need for environment protection, and energy security for sustainable development. It is estimated that of the total imports into India, 40 per cent comprises of petroleum products. These products are imported at very high prices and thus arises the need for their economical use said she.

Mehendale added that various camps are being regularly conducted for making the public aware of the importance of proper use of the petroleum products. People are also told about the ways and means by which they can save petrol as well as other products.

Citing an example, Mehendale said Godhav Rolling Mills in Mandi Gobindgarh, is conducting experiments to prevent the wastage of energy and to achieve the maximum energy level, which in turn has helped them in cutting down their over-all working costs.

Petrol-Alcohol-Water Microemulsion Fuel

Development of Petrol-Alcohol-Water Micro-emulsion Fuel as a Substitute for Petrol and Ethanol-Blended Petrol

In response to adverse environmental impacts from mass consumption of fossil petroleum fuels as well as international crude oil reserves being finite, most countries are attempting to find answers to meeting future demand for fuel for transport. Internationally, there is a growing acceptance that renewable ethanol fuel produced from biomass, with its associated environmental benefits, will be the transport fuel of choice for the future. Ethanol/ petroleum fuel blends directly address vehicle emissions and transport fuel security of supply issues. In addition to reducing currently regulated vehicle emissions, the renewable ethanol content of these fuels can result in a net reduction in the emission of unburnt hydrocarbons and particulate matter. Use of ethanol/ petroleum fuel blends initially in the existing vehicle fleet is essential to develop the technology and infrastructure necessary to support wide-scale production and use of ethanol fuel.
Petrol-alcohol-water based micro-emulsion fuel represents a new and potentially cost-effective option. Micro-emulsions are optically isotropic, transparent oil and water dispersions which are thermodynamically stable. Micro-emulsions have received considerable attention in recent years because of their interesting thermodynamic and physico-chemical behavior, and diverse applications. A lot of work has been done in areas like micro-emulsion gels and preparation of vitamin E emulsions. But preparation, characterization, and testing of micro-emulsion fuels, comprising of petrol and water, and especially of ethanol-blended petrol and water, remain virtually unexplored.
The petrol-alcohol-water based micro-emulsion fuel was prepared by stirring a blend of petrol, surfactant, co-surfactant, and water in definite proportions and it was produced under certain carefully defined conditions. To prepare a stable micro-emulsion fuel, a specific type of surfactant is required to be added in optimum quantity along with a co-surfactant, which in our case was ethanol (both anhydrous, and hydrous ethanol, i.e. ethanol obtained from sugar mills).
Experiments have been conducted to determine the minimum percentage of anhydrous ethanol that was needed to be added to the mixture of petrol and water, starting with fixed initial compositions of petrol (ranging from about 79%-99.5%)-and-water (ranging from about 0.5%-21%) mixtures. A fixed quantity of surfactant was added to this immiscible petrol-water mixture followed by a continuous addition of the co-surfactant (anhydrous ethanol) until a crystal clear mixture was obtained, i.e. a micro-emulsion (transparent and clear to the naked eye). Other sets of experiments were carried out by starting with fixed quantities of ethanol, surfactant, and petrol, followed by a continuous addition of the water to this mixture until it just about became turbid. A ternary phase diagram was plotted using these data. The diagram had ethanol and surfactant on one axis, water on another, and petrol on the third axis. A number of experiments were carried out to confirm the stability of all the compositions between the defined boundaries (which correspond to the stable micro-emulsion composition zone) by selecting some random compositions in between. Thus, the boundary compositions of petrol, ethanol, surfactant, water and the interior regions of composition were verified for the formation and stability of micro-emulsions.
Similar experiments were also carried out using ethanol obtained from sugar mills (hydrous ethanol) instead of anhydrous ethanol. In this case, fixed quantity of petrol, and surfactant was mixed in a 250 ml (air tight) sample bottle (Borosil). The resulting mixture was obviously turbid (unstable, two-phase region). Ethanol obtained from sugar mills (with different purities) was then added drop by drop with constant stirring, using a magnetic stirrer. The addition was continued till a clear transparent mixture was obtained indicating micro-emulsion formation. The procedure was repeated for different compositions of petrol, and surfactant.
Each micro-emulsion sample was kept separately in an airtight Borosil glass bottle and it was checked on everyday basis for any instability that could creep-in due to weather changes. Some of the samples were even kept in different environmental conditions to check for their stability. Use was made of an incubator to realize temperatures ranging from 0 oC to 40 oC. The micro-emulsions, which were stable on a particular day, did not necessarily imply that they would be stable afterwards. Some of them did become unstable (turbid) after some time, usually within days. The observed instability of micro-emulsions might have been due to the loss of co-surfactant (ethanol) by evaporation. Although the samples were kept in tightly closed sample bottles, the possibility of evaporation of the co-surfactant was still there. Another cause of instability of the micro-emulsion samples, occurring after some time, might be the change in the ambient temperature. In case a micro-emulsion sample turned unstable, it was stabilized using anhydrous ethanol and the composition of that particular micro-emulsion updated accordingly.
The results suggested that the formation of stable micro-emulsion started only at around 55 %v/v of ethanol. At high vol% of petrol (or low vol% of ethanol), a stable micro-emulsion was not obtained. The surfactant was quite effective in obtaining a stable micro-emulsion at a low volume percentage of about 0.29 – 0.33%. Using these experiments, we were successful in mapping the stable micro-emulsion zone on the ternary phase diagram for different compositions of petrol, anhydrous/hydrous ethanol, surfactant, and water.

mapping of animal Census data

mapping of animal Census data

MINUTES OF THE MEETING OF THE TECHNICAL COMMITTEE OF DIRECTION FOR IMPROVEMENT OF ANIMAL HUSBANDRY AND DAIRYING STATISTICS HELD DURING OCTOBER 05-06, 2006 AT PUNE
inaugural address

Smt. Leena Mehendale, Principal Secretary, ADF, Government of Maharashtra in her inaugural address expressed her great pleasure that the Government of India has chosen Pune for holding the TCD meeting. She mentioned that the development potential of Animal Husbandry, Dairying and Fisheries (ADF) is tremendous and planners may aspire to attain up to 10 % level of the growth rate. Information is an asset for planning. The ADF sector is very important from food security viewpoint. Agriculture and Animal Husbandry sector should go hand in hand. From energy point of view again, there exists substantial contribution potential from this sector. She suggested for the mapping of Census data which may mean convergence of many departments. Time series analysis and regression analysis should be put to use in order to understand numbers better. Total productivity and strategy for productivity increase will be different for different people. She illustrated this concept by giving the example of sheep rearing activity. It has different dimensions if its aims and hence people involved are different like for those pursuing for the life sustaining activity, for commercial or growth potential activity or for export base increase activity etc. In all such cases, for different people, different strategies of developments would be relevant. She appreciated calling TCD meeting at Pune as the participating officers would be free from all file works and would devote much of their time in deliberations. She wished a great success to the meeting in achieving its goal.

Energium 2004 brings to light need and measures of energy efficiency

E-Tex Staff - Mumbai

Energium 2004, organised jointly by the Petroleum Conservation Research Association (PCRA) and the United States - Environmental Resource Centre (US-ERC), in Mumbai recently, emphasised the need for energy efficiency, through its two-day conference, ‘Energy Efficiency in Commercial Establishments’. Speaking on the occasion, Ms Leena Mehendale, executive director, PCRA stated, “It’s not just enough to have energy efficient solutions, a change in attitude is is important, creating awareness about energy is important.”

Said Mr Suneel Parasnis, director general, United States - Asia Environmental Partnership/USAID, western region, in his address, said, “We have reached a situation where we are forced to adopt energy efficiency as a way of life and business. We have no option.”

According to Mr V S Verma, director general, Bureau of Energy Efficiency and Member Planning, Central Electricity Authority, “Per capita energy consumption in India is still very low when compared to that in the developed countries. However, the pressure to save energy is just as urgent here. While effecting savings, energy efficiency also results in better cost-competitiveness, and also reduction in greenhouse gas emissions. All these issues are becoming increasingly important in a global marketplace.”

He further stated that India has an energy shortage of around 17.1 per cent, and even as the higher energy generation of 41,000 MW in the 10th Plan will be achieved, the demand for energy is also increasing very fast, as standard of living improves. In this scenario, energy conservation and efficiency is the only way to move ahead,” he said.

According to Ms Mehendale, “There is still a lot that needs to be done towards energy conservation and efficiency. Awareness is sadly lacking. The Bureau of Indian Standards has prescribed norms for manufacturing of equipment, which have to be voluntarily applied, but we have come across a number of equipment which do not meet these standards. At times, simple adjustments in the design of equipment can lead to immense energy saving and better efficiency, but this is not done due to lack of knowledge. At other times, standards are not met as these require some amount of investment, making the product that much costlier, so energy efficiency is sacrificed for low costs. We have still a long way to go in creating awareness about energy efficiency and then getting people to adopt such systems and solutions.”

Speakers at the conference included Dr Pramod Deo, member, Maharashtra Electricity Regulatory Commission; Mr S Padmanaban, senior energy and environment advisor, USAID; Mr A U Diggikar, director general, Maharashtra Energy Development Agency; Dr Naval Karrir, director, Deloitte Touche Tohmatsu; Mr E S Balasubramaniam, DGM, State Bank of India; Mr Jaisingh Dhumal, chief manager, ICICI Bank; Mr Abraham Varghese, head, energy management group, Enercon Systems; Ms Rupa Devi Singh, director, power practice, CRISIL; among others.

Dr Pramod Deo, in his paper on ‘Regulatory Issues and Energy Efficiency in Commercial Establishments’ spoke about the Electricity Act 2003 (EC 2003), which addresses the issue of improvement of energy efficiency directly for supply options, while the demand side is left to the ingenuity of the state electricity regulation commissions (SERCs). “It is well known that in order to give rightful palce to demand side management options, the regulators need to adopt Integrated Energy Resource Planning (IREP). IREP evaluates demand and supply-side options and determines the optimal energy service strategy that takes account of economic and environment factors. This brings into sharp focus the use of alternative energy supply options.”

Mr S Padmanaban, in his paper on ‘Policy and program initiatives to advance energy efficiency in commercial establishments’ spoke of the need for design of conservation strategies in commercial establishments. “There was a misconception that buildings in India did not consume much energy. However, the ground realities were different: in city after city air conditioning was beginning to grow rapidly and together with lighting, is a major contributor to peak load. Today, efficiency opportunities are being recognised by commercial builders, building appliance vendors, architects and design firms, etc.” He further stated that three key areas need to be addressed - regulations and market-driven prices, innovative financing with emphasis on risk coverage, and transforming technologies to reflect enhanced energy efficiency.

The push to adopt energy efficient solutions and systems is also coming from the financial sector, which has put in place schemes to boost investment in such ventures. The State Bank Of India (SBI) has initiated the ‘Energy Efficiency Project’. “An amount of Rs 190 lakh has been set apart for implementation of this pilot project, covering 140 units across the country. The bank will identify units enjoying credit limits which have investments in plant and machinery less than Rs 10 crore. Consultants will be empanelled at various centres and walk-in audits conducted with their help. The consultants will study all aspects of energy management, as per the bank’s standard format, prepare detailed project report on energy efficiency measures and its implementation,” said Mr E S Balasubramanian, DGM, SBI.

Other topics discussed at the summit were the latest energy saving technologies, making buildings energy efficient, ESCO approach to guaranteed energy savings, energy auditing, etc.

Detergent, urea in your child’s milk


Aditya Ghosh, Hindustan Times
Email Author
Mumbai, June 16, 2007


One in every five packets of milk is adulterated in the state with chemicals such as caustic soda and urea.

While caustic soda, an acid found in detergents, damages the digestive tract including the stomach lining, urea can damage the urinary system and lead to the formation of stones in the kidney.

After a year’s investigation, the state Food and Drug Administration (FDA) released the findings about milk in Maharashtra on Friday.

It is now launching a massive drive to check milk quality across the state. Even tankers coming from outside the state will be stopped at highway checkposts and samples taken.

When two owners of large dairies were contacted, they said their dairies did not produce such adulterated milk and refused to say anything else.

Among 761 samples tested between April 2006 and May 2007 from state cooperatives as well as private diaries, 151 samples were adulterated.

A report on 100-odd samples is awaited. The adulterants varied from chemicals like washing soda and urea to non-synthetic material like palm oil, liquid glucose and lactose. The FDA refused to say which dairies it had taken samples from.

Prosecution has started in only 27 cases. Soon after the FDA received the report, a high-level meeting was convened by the Home Department in the Mantralaya.

“The chief minister had attended the meeting and we are trying to evolve some strategy to counter this. He wants to make provisions for much stronger punitive action against the offenders,” said outgoing principal secretary of animal husbandry and dairy development department Leena Mehendale.

“From June, we launched a massive operation and in eight days collected 53 samples, arrested four people. We are waiting for the reports on the samples,” said FDA Commissioner Amitabh Chandra.

The samples had urea higher than the safety limit of 700 ppm, which experts correlated with indiscriminate use of fertilisers in cattle fodder. “It is a strong possibility. Also, fertilisers seeping into groundwater are affecting the quality of grass,” said Pune-based veterinarian Aniruddha Belsare.

In Mumbai, experts said some dairies added urea as adulterant to enhance colour and texture. “However, they did not realise that the natural urea content in milk was increasing all the time because of rampant use of fertilisers in fodder. Now, it is crossing the safety threshold,” said Dr JC Khanna, secretary, Parel Animal Hospital.
