一、情况简述抚顺石油二厂烷基化车间的压力罐建于1966年,采用20G钢板焊接而成,筒体直径是2.6米。此罐是用来处理液态烃的。处理前液态烃中含H_2S约100ppm,将它与浓度为2～3%NaOH水溶液混合后装入压力罐中,罐内温度保持在35～40℃,压力是10kgf/cm~2。处理后的液烃从罐的上部管道中抽走,此时液态烃中H_2S含量降到20ppm。使用后的NaOH水溶液中含有H_2S,经沉降器由下
First, the situation briefly Fushun Petrochemical Plant alkylation plant pressure tank was built in 1966, welded with 20G steel, the cylinder diameter is 2.6 meters. This tank is used to treat liquid hydrocarbons. The pretreated liquid hydrocarbon contains about 100 ppm of H 2 S and is mixed with a 2 to 3% aqueous solution of NaOH and charged into a pressure tank maintained at a temperature of 35 to 40 ° C and a pressure of 10 kgf / cm 2. The treated liquid hydrocarbons are drawn from the top of the tank and the H 2 S content of the liquid hydrocarbons is reduced to 20 ppm. After use, the aqueous NaOH solution contains H 2 S and passes through the settler
