Abstract
Liquid oxygen and liquid nitrogen are produced from the separation of air in an installation of reduced size wherein the refrigeration necessary for the operation of the air separation unit is produced from the use of a single compander and a freon refrigeration unit affixed to a split-out stream of the main heat exchanger with appropriate recycling and heat exchange. The process for such an installation is also set forth.
