- 摘要:
为满足干气输送的要求,必须对凝析气田集气站的原料气进行三甘醇(TEG)脱水处理,处理过程中发现原料气的重烃对TEG脱水工艺的脱水效果影响很大,TEG溶液夹带重烃后容易造成TEG溶液循环泵振动、TEG溶液过滤器频繁堵塞、废气灼烧炉振动及超温等问题,影响TEG脱水装置平稳运行。结合国外某凝析气田集气站TEG脱水装置的设计、运行情况,对存在问题进行了详细分析,提出了优化措施。通过现场应用及模拟计算可知优化措施切实有效,可为类似凝析气田集气站TEG脱水装置的建设提供借鉴。
In order to meet the requirement of dry gas transportation, a gas gathering station of condensate gas field needs to apply TEG dehydration process on raw gas. It is found that the heavy hydrocarbons of raw gas has great influence on the TEG dehydration process. If heavy hydrocarbons are entrained in the TEG solution, it will cause problems such as vibration of the TEG circulating pump, frequent blockage of the TEG filter and vibration and over-heating of the tail gas incinerator, affecting the smooth operation of the process unit. Taking into consideration the design and operation experience of the TEG dehydration unit of the gas gathering station of condensate gas field, this paper analyzed the existing problems in detail and proposed optimization measures. By field application and simulation of the optimization measures, it is shown that the proposed optimization measures are pragmatic and effective, and can provide reference for the development and construction of TEG dehydration systems in similar condensate gas fields.
