Sulfur-containing liquefied gas can cause adverse effects on the environment , human and downstream chemical production are liquefied gas desulfurization significance . With the enhancement of environmental awareness , the liquefied gas desulfurization in our country also gaining attention. Firstly liquefied gas desulfurizer, desulfurization method , liquefied gas desulfurization domestic research situation at home and abroad desulfurization technology progress are reviewed. Combined with two sets of Jinxi Petrochemical Company liquefied gas desulfurization desulfurization principles , processes , and joint regeneration process , the nature of raw materials , product quality concrete production , purification the liquefied sulfur reasons and liquefied copper corrosion unqualified mechanism , pointing out that the impact of purifying the liquefied gas copper corrosion unqualified factor . Detected by in-depth analysis of Jinxi Petrochemical Company two sets of liquefied gas desulfurization equipment desulfurization condition liquefied gas desulfurization problem . Application Jinxi Petrochemical Company liquefied -alkali combined process desulfurization pilot reached : COS hydrolysis agent , fine desulfurizer , mercaptan conversion catalyst three fixed bed series , namely JX-6B JX-2B JX- 2A, substitute liquefied the alcohol amine washed the pre- caustic washing and the Merox law sweetening process to achieve residual liquefied gas in the fixed bed removal of H2S , COS , and mercaptans transformation , the process is simplified , eliminating the caustic sludge . Coking combination of Jinxi Petrochemical Company , two catalytic three catalytic liquefied gas , a liquefied gas desulfurization , two sets of liquefied gas desulphurization and heavy of catalytic exhaust hydrogenation device specific production situation , put forward to solve Jinxi Petrochemical Company Liquefied Gas Desulfurization device problems specific programs.
