PRODUKSI GAS NITROGEN DENGAN METODE PRESSURE SWING ADSORPTION (PSA) MENGGUNAKAN CARBON MOLECULAR SIEVE (CMS) SEBAGAI PENYERAP OKSIGEN

Abstract

Air is one of the needs always used by living things directly or indirectly. The composition of the air consists of nitrogen, oxygen, argon, and carbon dioxide as well as the number of other constituents that are very small. One important component of air is nitrogen gas. With such a large amount, nitrogen gas can be utilized for several uses, among others in the fertilizer industry, and as an air filler press on vehicle tires. One method of air separation to obtain nitrogen gas is the Pressure Swing Adsorption (PSA) method. Adsorption is a process whereby fluid molecules touch and attach to the solid surface. The PSA process uses a compressor as an air supply. Air is fed to the PSA column by adjusting the feed pressure, then air will be separated between O2 and N2 by using Carbon Molecular Sieve (CMS) adsorbers as absorbents in the PSA column. Pressure and time variations were performed with the aim to see the effect of CMS saturation and regeneration on the resulting Nitrogen content.
