Abstract
This report about Industrial gases liquefaction consists of five chapters. Chapter one consists of general introduction containing historical back ground, summary for the process and basic concepts .. Chapter two talks about the main component like compressors, heat exchangers, expanders, different kind of valves, separator air coolers, cooling towers and distillation columns. Chapter three talks about the cycles of refrigeration starting from the basic cycles and the different cycles used in the liquefaction process (linde ,Claude and cascade system).Chapter four involves the air separation process especially (Oxygen,Nitrogen,Argon) with an example for (Oxygen,Nitrogen,Argon) separation unit and analysis for the unit. Chapter five involves in the natural gas processing and liquefaction with an example for a liquefaction unit for lNG and analysis for the cycle
