Pengaruh Tekanan terhadap Suhu Oksigen dan Nitrogen pada Proses Pemisahan Udara Secara Destilasi di PT Aneka Gas Industri

Abstract

Has been done research about the influence of pressure on the temperature of oxygen and nitrogen in the air separation process by distillation. The air contains 20.95% oxygen, 78.08% nitrogen and 0.97% other elements. For the separate oxygen and nitrogen from the air to very low temperatures is required to separate it and turn it into a liquid, the temperature of oxygen reached -177.8 oC, and nitrogen reached -184.0 oC. This process is influenced by pressure contained in the distillation column with the optimum pressure of 5.02 kg/cm2. Where the greater pressure given the temperature will be higher and vice versa.
