摘　　要：介绍了国内油田伴生气脱硫净化过程中存在的主要问题:一是伴生气脱硫塔效率较低,产品天然气质量不达标;二是脱硫塔运行过程中频繁出现发泡拦液现象,脱硫塔无法稳定运行;三是由于胺液的黏度发生改变导致脱硫塔传质效率低、产品硫含量超标。采用FMP塔盘技术可以实现将传统脱硫塔的鼓泡传质过程改为立式喷射态传质过程;可以彻底解决脱硫塔发泡拦液所造成的运行不稳定和脱硫效率低的问题。This paper introduces three main problems in the desulfurization and purification process of oilfields associated gas in China.Firstly,the efficiency of the desulfurization tower is very low,leading to unqualified natural gas product.Secondly,the desulfurization tower cannot run stably and there happens frequently the phenomena that liquid is blocked by foaming in the operation process. Thirdly,the mass transfer efficiency in desulfurization tower is low mainly due to the change of the viscosity of the amine solution,which in turn results in excessive sulfur content in the product.The FMP tray technology can help to change the traditional bubble-mass transfer process in desulfurization tower into a vertical jet state transfer process,which can solve thoroughly the problems of unstable operation and low desulfurization efficiency caused by foaming to block liquid in desulfurization tower.
