摘要
凝析气田天然气中含有丰富的轻烃组分。根据原料气独有的特点对不同的制冷工艺进行比选,在对现有回收工艺进行定性对比的基础上,运用HYSYS软件对所选工艺进行模拟,对工艺进行定量比选。并对所选直接换热(DHX)轻烃回收工艺分别进行流程及参数优化。结果表明,优化后的工艺方案流程更加简单,当膨胀比为1.79时,净收益最高。
Natural gas of condensate field is rich in light hydrocarbons composition.In this paper,according to the unique characteristics of the feed gas,different refrigeration technologies were compared and selected.Quantitative comparison was carried out on the process using HYSYS software to carry on the simulation of the selected technology on the basis of qualitative comparison of the existing recycling process.The process and parameters are optimized respectively,according to the selected direct heat exchanger（DHX）light hydrocarbon recovery process.The results showed that the optimized process plan flow was more simple,and when the expansion ratio was 1.79,the highest net income was realized.
