| Summary: | Recently, the depletion of fossil fuel reserves and the harmful environmental effects caused by burning fossil fuels have signified the supreme importance of utilizing sustainable energy reserves such as geothermal and solar energies. The advancement of the Organic Rankine Cycle as a clean energy generation path by researchers has gained momentous demand for its commercialization. The sole Organic Rankine Cycle can produce a large amount of energy in contrast to other power production cycles. To make this clean energy recovery sustainable, liquefied natural gas cold energy can be utilized through regasification to integrate the Organic Rankine Cycle with the anti-sublimation carbon dioxide capture process, merging the biogas setup. Liquefied natural gas cold energy recovery has paramount importance with aspects of energy economy and environment preservation. Liquefied natural gas regasification in shell and tube heat exchangers poses a minimal freezing risk and is high duty. Anti-sublimation of biogas is an energy-intensive process. It can be materialized from liquefied natural gas cold energy implementation through the Organic Rankine Cycle by maintaining cryogenic temperatures there. In this situation, greenhouse gas emissions can be minimized. The simulation analysis is performed based on thermodynamic and techno-economic assessments of the poly-generation energy systems. It is proved to be useful in conducting by regulating different working fluids. The optimum electric power generated is 2492 MW. While the optimum net present value, energy efficiency, and exergy efficiency of this proposed energy system are 19.5, 57.13%, and 76.20%, respectively. The governmental authorities and environmental protection can benefit from this scientific research work to create an environmentally friendly atmosphere and energy for contemporary society. |
