Abstract

A design of a liquid nitrogen generator using a Norelco refrigerator is shown in Figure 1. The cycle was suggested by S. c. Collins of M. I. T. and has been developed by Arthur D. Little, Inc. It has three essential parts consisting of a heat exchanger, a rectification column, and a refrigerator. The refrigerator condenses the vapor flowing from the top of the rectifier, and through the liquefied vapor returned to the rectifier as liquid reflux furnishes the refrigeration needed for the rectifier and heat exchanger. The heat exchanger functions as a refrigeration-purifier removing moisture and carbon dioxide from the feed air before entering the rectifier.
