Environment pollution by thermal power plants severely affects the global warming. It is necessary to avoid harmful gases getting into the atmospheric air. In order to achieve this several techniques are followed by the industries. All the technical solutions like post combustion gas capturing technique, capturing prior to combustion, absorption of gas, Membrane separation using chemicals and adsorption resulted with some difficulties and needs to be developed. This evolved the aspect of cryogenic distillation a recent trend of research towards the capturing of the harmful gases. Technically speaking the process of cryogenic distillation needs a cryocooler. Thus a Stirling cryocooler is to be analyzed by considering that it is in the application of cryogenic distillation . Thermodynamic parameters for the all four processes namely Compressing process Iso-thermally, Constant volume Heat-addition, Expansion process Iso-thermally, Constant volume Heat removal, Total heat input, Total heat rejection and Network are calculated by considering nominal values of volume ratio and Specific heat. The methodology is applied for cooling of CO2 and N2 by the various working fluids like Helium and LNG. The present work is related to thermodynamic analysis of Stirling engine by considering that the cryocooler runs based on Stirling cycle and is working for solidification of emissions from Thermal power plants.
