Why Engage AEPL

This is a very pertinent question as to why industrial houses with their vast resources not only in the key area of business but also in technical manpower would go for an engineering service provider like us. The answer lies in our panoramic exposure to various kinds of projects, several vendors of similar equipment, various site-specific constraints and above all a pool of engineers with focus on optimization of design, implementation and minimizing cost. As a result, we can put on table before our customers various unbiased options for his final decision.

Standing on a solid foundation of classical engineering, Astha team is equally receptive of latest developments in the relevant field and tries to explore the possibility of implementing such technology in the ongoing contracts without, of course, compromising the safety, cost and quality. In this process, the team always takes into confidence the customers, most of whom are knowledgeable and pragmatic and have rich experience of operation and trouble-shooting of their plants. The interaction breeds an engineering useful to all stakeholders in the industry. Even customers with fixed preference for processes with which they are accustomed so far, when presented with other options, with pros and cons, appreciate most of the time the true value of engineering offered by Astha and retain as their lifelong partner. The nominal fees of engineering has a multiplier effect in savings in operation and capital costs of a project.

AEPL now takes interest in following areas also.

Energy Efficiency

Efficient use of energy is always one of the main objectives of good engineering practice. Improvements in equipment design, introduction of new equipment for energy efficiency (e.g., variable frequency drive), intelligent controls can help in substantially improving the energy efficiency of a plant. This is becoming more and more relevant for all plants in the light of environmental concern, limited availability of resources and of course, cost optimization. Energy is consumed in a plant mostly in the form of heat and electricity. A systematic approach to identify and optimize use of these is required in achieving the goal. AEPL can offer services for such work.

Water Reuse

Depletion of fresh water resources is a global environmental concern. Industrial plants use huge quantities of water for cooling and other purposes. Inland plants use river or ground water while coastal plants use sea or brackish water after proper treatment. The quality of water required for various processes in a plant is not unique and effluent from one can be re-used in another with proper treatment. In the past, such re-use was not in agenda of plant management and many plants, specifically chemical plants, became notoriously famous for polluting the surrounding water bodies and surface drains beyond plant boundary. Environmental awareness and public opinion have changed this trend with regulatory pressures and penalties for violation of established limits. In fact, ZLD or zero liquid discharge is a common acronym nowadays in plant circles. However, ZLD requires preparation of a detailed balance sheet of ongoing water usage, analysis & identifying areas of rebalancing. AEPL can assist customers in a systematic manner.

Sulfur Extraction from Sewage Gas

Bio-gas generated from sewage treatment is a potential source of energy. The energy requirement of operation of a sewage treatment plant (STP) can be partially met from the generated gas itself, making the plant almost carbon neutral and economic. Therefore, there is a case for inclusion of gas recovery equipment in a STP, particularly in the context of climate change. However, Hydrogen Sulfide (H2S) which is present in the gas is toxic and corrosive. It is required to be removed before feeding the gas to an engine or a boiler for power generation. H2S concentration should be less than 1000ppm for an IC engine depending on the manufacturer’s recommendation. IISc, Bangalore has a patented process for removal of H2S from the bio-gas and collection of sulfur, which has a commercial value, making the installation even more economically attractive. AEPL holds a license for this process from IISc and is, therefore, poised to offer the technology to prospective clients.

Solar Energy

Power generation using solar PV cells on roof-top or at ground level is a very common application and is getting popular every day. Standard modules are available for residential and small commercial installations. However, one will not get the full benefit of economy unless the installation is properly engineered. This is an important consideration for industrial plants, where true benefit can only be realized when power withdrawal from grid can be reduced. Grid connection poses technical complexities as well as interaction with utility provider. Similarly, for a relatively large installation, solar irradiation mapping, module cleaning and maintenance are other issues to be considered. Further, for an industrial plant, solar energy use is not necessarily confined to power generation. Industrial heating, heat pump type applications can also be areas of interest. AEPL can participate in such studies.

Waste To Energy

Any kind of bio-waste (e.g., municipal solid waste or MSW, rice husk or similar crop residue etc.) has an energy potential, which can be commercially exploited. Unless this is done, disposal of MSW or crop residue after harvesting can become a menace and an environmental bomb shell. Rapid urbanization, shortage of land for disposal and mounting pressure for pollution control makes waste-to-energy a fit case for adoption by the government/municipal bodies and even private industries for captive generation where feasible. As generation for fossil fuel is mandated to be reduced, this kind of generation, out of necessity to manage waste, can complement, at least partially, the shortfall in stable power.
