Ukubuyiswa okuphelele kwe-LPG noma i-condensate kusuka kugesi yemvelo
Konke I-LPG noma ukululama kwe-condensate kusuka kugesi yemvelo kufaka phakathi iyunithi yokususa i-carbonization (ebizwa nangokuthi iyunithi yokususa i-CO2), iyunithi yokususa i-sulfurization, iyunithi yokuphelelwa amanzi emzimbeni, ukubuyiswa kwe-LPG kusuka kugesi yemvelo (noma Ukubuyiswa kwe-NGL kusuka kugesi yemvelo ), Iyunithi yokuhlukanisa kanye nokuhlukanisa igesi yemvelo, uhlelo lokulayisha, izinsiza, njalo njalo.
Nasi isibonelo esisodwa senqubo yaso.
Igesi yemvelo enomfutho ongu-995 ~ 1100psig kanye nokushisa okungu-75.19 ~ 95.43 ℉ ilawulwa ingcindezi, ihlungwe, ihlukaniswe, futhi ilinganiswe, bese kushintshaniswa ukushisa negesi eyomile kusuka ku-plate-fin heat exchanger bese ihlukaniswa. Igesi ehlukanisiwe ingena ohlelweni lokususa i-acid ukuze isuse i-CO2 \ H2S. Igesi yemvelo esusiwe ipholiswa kusengaphambili ku-20 ℃ ngumshini weqhwa oshisa kakhulu bese ihlukaniswa ibe yigesi noketshezi. Igesi yemvelo ehlukanisiwe isuswa amanzi ngohlelo lokomisa lwesihlungo sama-molecule, bese isuswa i-mercury bese ihluzwa uthuli, bese ingena ku-plate-fin heat exchanger ukuze iphole ku- -29 ℃, bese iqhubeka iphola ku- -35 ℃ nge-propane refrigeration compressor ngaphambi kokungena ku-separator yokushisa okuphansi. Ama-hydrocarbons aketshezi angaphansi kwe-separator yokushisa okuphansi acindezelwa yi-throttle valve bese ingena ku-plate-fin heat exchanger ukuze iphinde ifudumale ku-20 ℃ ngaphambi kokungena phakathi kwe-de-ethanizer. Igesi ephezulu kwesihlukanisi sokushisa okuphansi inwetshwa ibe ngu-~2.485MPa nge-expander bese ingena engxenyeni engezansi yombhoshongo we-DHX, lapho ixhumana khona nama-hydrocarbon apholile asuka phezulu kwe-deethanizer, futhi iningi lezingxenye ze-C3 nangaphezulu kugesi eluhlaza ziyamuncwa. Ama-hydrocarbon aketshezi phansi kombhoshongo we-DHX acindezelwa yipompo yokuxuba i-hydrocarbon bese engena phezulu kwe-deethanizer, lapho i-ethane eningi isuswa yi-reboiler phansi kwe-deethanizer. Igesi ecebile nge-ethane ekhishwe phezulu kombhoshongo ingena ku-plate-fin heat exchanger futhi ipholiswa ngaphambi kokungena phezulu kombhoshongo we-DHX, kuqedwe umjikelezo. Igesi eyomile phezulu kombhoshongo we-DHX ingena ku-plate-fin heat exchanger ukuze ifudumale futhi bese ithuthwa ikhishwe ngemuva kokucindezelwa ku-~7.6Mpa yi-dry compressor. Ama-hydrocarbon acwebezelayo angaphansi kombhoshongo we-deethanizer aya embhoshongweni wegesi oncibilikisiwe ngokucindezela kwawo. Umkhiqizo we-LPG okhiqizwa phezulu kombhoshongo ungena ethangini lokugcina, kanti i-C5 + ephansi kombhoshongo ingena ethangini lokugcina njengomkhiqizo we-C5 + ngemva kokuphola ku-40 ℃.
Ama-hydrocarbon aketshezi ahlukaniswe ngokuhluzwa ngemva kokulawulwa kwengcindezi yegesi eluhlaza kanye nama-hydrocarbon aketshezi ngemva kokupholisa ngaphambi kokupholisa angena esihlukanisi sezigaba ezintathu, kanti ama-hydrocarbon aketshezi ahlukene angena ku-deethanizer. Igesi ijikeleziswa esihlukanisini sesihlungi sokungena ukuze ibuyiselwe nge-compressor yokujikeleza kwegesi ye-flash, bese amanzi angcolile angena eyunithi yokuqoqwa kwamanzi angcolile.
