摘要
普光天然气净化厂脱硫部分采用Black﹠Veatch公司的专利技术,两级吸收、级间冷却选择性脱除H2S。二级吸收塔主要用来控制对CO2的吸收,CO2的吸收程度不仅对产品气热值影响较大,而且影响后续克劳斯单元及斯科特单元的操作。本文通过对吸收单元工艺参数进行优化,寻找出合适的工艺参数组,应用结果显示,效果显著。
Black Veatch＇s patented technology,two stage absorption,interstage cooling was used in Puguang natural gas purification plant desulfurization for selective removal of H2S.Two stage absorption tower was mainly used to control the absorption of CO2,whose degree effected not only on the product gas calorific value impact,but also on the subsequent Claus unit and the Scott unit operation.The suitable process parameter group through the process optimization.Application results showed that the effect was notable.
