基于层次分析法优化天然气净化工艺
Optimization of purification process for natural gas using analytic hierarchy process
摘要
Abstract
In order to avoid severe corrosion of vessel or freezing in cryogenic exchangers,feed gas from natural gas well heads containing various contaminants and acid gases cannot be sent to the liquefaction unit directly,and must pass through purification units to remove undesirable components such as CO2, H2S and H2O. In this paper,DEA and TEG methods are adopted to remove such components,and these two methods are coupled into a natural gas purification process to reach the purification target. As the project handbook only gives the approximate range of process parameters,an optimal process is not available. This paper first applies software HYSYS 8.4 to simulate the natural gas purification process based on relevant data. Then nine combined cases are listed according to the recommended range of process parameters,and a system assessment method,Analytic Hierarchy Process (AHP),is introduced. Finally,multi-objective comprehensive assessment is made using AHP in Matlab to select the optimal process parameters. This approach can provide reference for optimization of natural gas purification process and other processes.关键词
