【摘要】：在對(duì)高壓凝析氣田氣回收乙烷及以上組分時(shí),可利用的現(xiàn)有乙烷回收流程存在系統(tǒng)冷量過多、脫甲烷塔氣液分離效果差和系統(tǒng)能耗高等問題。在部分干氣循環(huán)工藝(RSV)的基礎(chǔ)上,提出一種高壓天然氣的乙烷回收高效流程(HPARV)。該流程在RSV工藝的基礎(chǔ)上增加了1臺(tái)高壓吸收塔,吸收塔與脫甲烷塔的操作壓力相互獨(dú)立,既保證了較高的乙烷回收率,又降低了外輸干氣的再壓縮功率。HPARV工藝有效解決了傳統(tǒng)RSV乙烷回收流程系統(tǒng)能耗高、對(duì)高壓原料氣適應(yīng)性不強(qiáng)和脫甲烷塔氣液分離效率差等問題。研究實(shí)例表明,當(dāng)原料氣壓力大于7.0MPa時(shí),HPARV工藝對(duì)原料氣氣質(zhì)組分變化及原料氣壓力變化均具有較好的適應(yīng)性,乙烷回收率高達(dá)93%以上。與相同乙烷回收率下的RSV工藝相比,HPARV工藝能大幅度降低乙烷回收裝置的綜合能耗。
[Abstract]:When ethane and above components are recovered from gas in high pressure condensate gas field, there are some problems such as excessive system cooling, poor gas-liquid separation efficiency and high energy consumption in the available ethane recovery process. On the basis of partial dry gas circulation process (RSVV), an efficient ethane recovery process for high pressure natural gas (HPARV) was proposed. On the basis of the RSV process, a high pressure absorber is added. The operation pressure of the absorber and the demethanation tower is independent, and the higher ethane recovery rate is ensured. The recompression power. HPARV process can effectively solve the problems such as high energy consumption of traditional RSV ethane recovery process, poor adaptability to high-pressure feedstock gas and poor gas-liquid separation efficiency of demethane tower. The example shows that the HPARV process has good adaptability to the change of gas composition and pressure of raw gas when the pressure of raw gas is greater than 7.0MPa, and the recovery rate of ethane is over 93%. Compared with the RSV process with the same ethane recovery rate, the HPARV process can greatly reduce the comprehensive energy consumption of the ethane recovery unit.
