Analisa Larutan Karbonat dan diethanolamine (DEA) dengan Metode Benfield terhadap Pemurnian Gas CO2 dan H2S pada Pengolahan Liquefied Natural Gas (LNG) di PT. ARUN NGL Lhokseumawe

Abstract

Purification of CO2 and H2S in the feed gas can be removed with a solution of carbonate and diethanolamin. The values that determine the optimal absorption process takes place in a solution that is specific gravity (SG),% K2CO3,% KHCO3, K2CO3 equivalence, % DEA in lean carbonate, % carbonate in the lean DEA, % DEA, factor convert, foaming test, collapse time, and particulate matter. Value % K2CO3, % KHCO3, equivalence of K2CO3, % DEA in lean carbonate, % carbonate in the lean DEA, % DEA, factor convert, determined by titration using HCl 0.1N Acydimetric as pentiter substance and with the addition of phenolphthalein indicator, while the value of SG, measured with a Hydrometer with archimedes principle of law, to the value collapse time and foaming test was determined by means of tests and stopwatches, and for particulate matter was determined by gravimetry. SG values, % K2CO3, % KHCO3, equivalence of K2CO3, % DEA in lean carbonate, factor concert, foaming test, collapse time, and particulate matter in the lean carbonate solution on 12,13,14th February 2014 are 1.2763, 1.2766, 1.2769, 21.19, 21.10, 21.17, 14.84, 14.54, 14.75, 31.45, 31.16, 31.37, -, 0.22 -, 0.32, 0.32, 0.32, 2, 2.25, 1.25, 1.45, 1.75, 0.6, -, 18, -. SG values,% DEA,% carbonate in the lean DEA, a foaming formation, collapse time, and particulate matter in solution diethanolamin lean on 12,13,14th February 2014 are 0.9912, 0.9903, 0.9912, 20.67, 21.01, 20.10, -, 12.11 , -, 1.0, 1.0, 1.0, 0.6, 0.5, 0.5, -, 19.5, -.
