Experimental investigations on a mixed refrigerant nitrogen liquefier.

Number: pap. ID: 647

Author(s) : SIVA SANKAR M., VENKATARATHNAM G.

Summary

This paper describes the performance of a small scale nitrogen liquefier working on a precooled mixed refrigerant process at different nitrogen feed flow rates (0.2,0.25 & 0.3 g/s) and different feed pressures (7-13 bar). A highest liquid nitrogen collection rate of 530 ml/hr of usable nitrogen was obtained with a power consumption of 1.5 kW. A highest liquefier exergy efficiency of 5% was obtained with this prototype. The ways of improving the performance are highlighted.
