SOLUBILITY OF PROPANE AND ETHANE IN LIQUID OXYGEN

摘要

Industry is large consumer of air gases for many and varied applications. Among the various processes of separation of air components, the most employed remains fractional distillation at low temperatures. The presence of pollutants - like hydrocarbons - in the feed atmospheric air of air distillation units (ASU) can be at the origin of drastic dysfunctions. That is the reason why a more accurate knowledge of the solubility of hydrocarbons in liquid oxygen and of the thermodynamic behaviour of these flammable systems under process operating conditions (from 93 to 153 K) would improve both evaluation and control of the risks specific to ASU and their performances.
