番禺气田三甘醇酸化问题分析及解决措施

Analysis and solution of acidulated TEG in PY30-1 Gasfield

番禺30-1气田三甘醇脱水装置在生产运行一段时间后发现因三甘醇酸化而影响脱水效果,使外输干气含水量上升的问题。介绍了三甘醇脱水工艺的流程,并运用色谱法测定了贫富甘醇的组分,分析了三甘醇酸化的原因,提出了三甘醇酸化问题的解决措施,经现场应用取得了良好的效果。三甘醇酸化问题的解决,降低了三甘醇损耗,保证了脱水系统正常运行,为解决类似工程问题提供了借鉴。

This paper introduces the dehydration and regeneration process of TEG in PY30-1DPP(drilling production platform).Acidification of TEG occurred after a period of operation,which not only influenced the efficiency of dehydration,but also led to an increase of the moisture content in the external transported dry gas.Chromatography is used to analyze the components of the lean and rich TEG.Causes and proposal measures are proposed,and good effects are achieved.The solving of the acidifying TEG reduces the TEG loss,ensures TEG process running smoothly,and provides guidance for similar projects.
