近年来,罗马尼亚设计了用火山质凝灰岩对天然气和伴生气作了干燥处理的工艺流程,并为三套装置所作的工业性试验确认。目前,已有五套处理天然气的装置和四套处理伴生气的装置采用该法。用凝灰岩对天然气进行干燥处理的过程为: (1)先对天然气用色谱法进行组分分析;(2)使天然气在20℃温度和常压下流经两个盛水容器,经鼓泡作用使其含水量达到饱和;(3)使天然气流经一填满凝灰岩的弯管;(4)弯管中排出的天然气引入盛有甲醇的罐中并使其发泡,同时通过用Karl Fischer反应剂自动滴定连续监测其含水量。解吸时间为干燥时间的2/3,用加热到250℃由五氧化二磷干燥的气体进行。流量为湿气流量的l/3。将从凝灰岩中解吸的水置入冷却到-20℃的乙二醇容器中,并通过称容器的重量测量水量。被解
In recent years, Romania has designed a process for the drying treatment of natural gas and associated gas with volcanic tuffs, and confirmed industrial tests on three installations. At present, five sets of natural gas-handling equipment and four sets of gas-handling equipment have been adopted. The process of drying natural gas with tuff is as follows: (1) The natural gas is first analyzed by chromatography; (2) Natural gas is made to flow through two water containers at a temperature of 20 ° C (3) passing the natural gas through a tuff-filled elbow; (4) discharging the natural gas from the elbow into a tank containing methanol and bubbling it, while the natural gas is passed through a Karl Fischer reaction Automatic titration continuously monitors its water content. The desorption time was 2/3 of the drying time, with a gas heated from phosphorus pentoxide heated to 250 ° C. The flow rate is 1/3 of the moisture flow rate. The water desorbed from the tuff was placed in a glycol container cooled to -20C and the amount of water was measured by the weight of the container. Be solved
