The indigenous Helium Refrigerator/Liquefier (HRL) plant being designed at IPR will have oil removal system for removal of compressor oil. After bulk oil removal in the Primary oil removal system (PORS), still significant oil is left in the helium stream which is removed first by a series of coalescers and then by an adsorber bed at 300k and 14 bar. At the charcoal bed the amount of oil at the inlet is about 1 PPM by volume and outlet is 0.01 PPM or about. This work is related to the static adsorption capacity and adsorption kinetics for organic compounds on coconut shell based activated carbon using Dubinin-Radushkevich. The adsorber bed design includes calculation size of adsorber bed, the pressure drop and MTZ length calculation using Rosen Model and Axial Dispersion Model. Finally it passes through a filter to restrict the carbon dusts coming out of the charcoal bed.
