Analysis of solvent loss in natural gas triethylene glycol dehydration unit
摘要
Abstract
Objective The aim is to reduce the triethylene glycol(TEG)loss in the TEG dehydration process.Method Based on the TEG dehydration process flow of actual production,various simulation analysis softwares were used to analyze the solvent loss in the whole process of natural gas TEG dehydration process.The locations of solvent loss were identified,and the dynamic characteristics of TEG carryover loss under different operating conditions were analyzed.Result The absorber was identified as the primary location of TEG loss,accounting for 77.87%of the total loss,with a simulated loss of 6.03 mg/m3.After optimization,the capture efficiency of the mesh demister of absorber was improved to 60.32%,and the separation efficiency of the product gas separator was improved to 93.10%.Conclusion The majority of TEG loss occurs in the absorber.Optimizing the structure of the mesh demister and the product gas separator can significantly reduce TEG carryover loss.It is recommended to strengthen daily operation management and improve equipment structure to improve the operational efficiency and economic performance of the dehydration unit.关键词
