An experimental study of desublimation of carbon dioxide from a gas mixture

Abstract

An experimental study of the desublimation of carbon dioxide from a gas mixture with nitrogen on a cooled surface was performed. A test bench for the study of desublimation process comprised a gas mixture source, a measurement cell, a cooling system, a vacuum system, and a control and measuring system. The main factors that influence the degree of recovery of carbon dioxide were determined. Empirical dependences of the degree of recovery of carbon dioxide on the process parameters were obtained. The possibility of the commercial implementation of the process is discussed.
