Ukubuyiswa kwe-LPG okanye i-condensate epheleleyo kwigesi yendalo
Yonke I-LPG okanye ukubuyiselwa kwe-condensate kwigesi yendalo kuquka iyunithi yokususa iicarbonization (ekwabizwa ngokuba yiyunithi yokususa i-CO2), iyunithi yokususa i-sulfurization, iyunithi yokuphelisa amanzi emzimbeni, ukufunyanwa kwe-LPG kwigesi yendalo (okanye Ukufunyanwa kwe-NGL kwigesi yendalo ), Iyunithi yokwahlulahlula kunye nokwahlulahlula igesi yendalo, inkqubo yokulayisha, usetyenziso, njalo njalo.
Nantsi imizekelo yenkqubo yayo.
Igesi yendalo enoxinzelelo lwe-995 ~ 1100psig kunye nobushushu obuyi-75.19 ~ 95.43 ℉ ilawulwa uxinzelelo, ihluzwe, yahlulwe, kwaye ilinganiswe, ize emva koko itshintshiselwe ubushushu negesi eyomileyo kwi-plate-fin heat exchanger ize yahlulwe. Igesi eyahlukileyo ingena kwinkqubo ye-de-acidification ukuze isuse i-CO2 \ H2S. Igesi yendalo e-de-acidified ipholiswa kwangaphambili ukuya kwi-20 ℃ ngumatshini womkhenkce obushushu obuphezulu ize yahlulwe ibe yigesi kunye nolwelo. Igesi yendalo eyahlukileyo ikhutshwa yinkqubo yokomisa ngesihluzo se-molecular, ize isuswe i-mercury ize ihluzwe uthuli, ize ingene kwi-plate-fin heat exchanger ukuze iphole ukuya kwi- -29 ℃, ize iqhubeke iphole ukuya kwi- -35 ℃ yi-propane refrigeration compressor ngaphambi kokuba ingene kwi-low-temperature separator. Ii-hydrocarbons ezingamanzi ezisezantsi kwe-low-temperature separator zigxothwa yi-throttle valve kwaye zingene kwi-plate-fin heat exchanger ukuze zifudumale ukuya kwi-20 ℃ ngaphambi kokuba zingene embindini we-de-ethanizer. Igesi ephezulu kwisahluli sobushushu obuphantsi iyandiswa ukuya kwi ~ 2.485MPa ngesandisi-manzi ize ingene kwinxalenye esezantsi ye-DHX tower, apho idibana khona ngoku ne-hydrocarbons ezimanzi ezipholileyo ezivela phezulu kwe-deethanizer, kwaye uninzi lwezinto ze-C3 nangaphezulu kwigesi eluhlaza ziyafunxwa. Ii-hydrocarbons ezingamanzi ezisezantsi kwe-DHX tower zicinezelwa yipompo yokuxuba i-hydrocarbon kwaye zingena phezulu kwe-deethanizer, apho i-ethane engaphezulu isuswa yi-reboiler esezantsi kwe-deethanizer. Igesi etyebileyo ye-ethane ekhutshwe phezulu kwe-tower ingena kwi-plate-fin heat exchanger kwaye ipholiswe ngaphambi kokuba ingene phezulu kwe-DHX tower, igqibezele umjikelo. Igesi eyomileyo ephezulu kwi-DHX tower ingena kwi-plate-fin heat exchanger ukuze ifudumale kwakhona kwaye emva koko ithuthwa iphume emva kokuba icinezelwe ukuya kwi ~7.6Mpa yi-dry compressor. Iihydrocarbon ezingamanzi ezisezantsi kwenqaba ye-deethanizer ziya kwinqaba yegesi enyibilikisiweyo ngoxinzelelo lwazo. Imveliso ye-LPG eveliswa phezulu kwenqaba ingena kwitanki yokugcina, kwaye i-C5 + esezantsi kwenqaba ingena kwitanki yokugcina njengemveliso ye-C5 + emva kokuba ipholisiwe ukuya kuma-40 ℃.
Iihydrocarbon ezingamanzi ezahlulwe ngokuhluzwa emva kokulawulwa koxinzelelo lwegesi eluhlaza kunye neehydrocarbon ezingamanzi emva kokuba zipholile ngaphambi kokuba ziphole zingena kwi-separator yezigaba ezintathu, kwaye iihydrocarbon ezingamanzi ezahlulweyo zingena kwi-deethanizer. Igesi ijikeleziswa kwi-inlet filter separator ukuze ibuyiselwe kwi-compressor ye-flash gas circulation, kwaye amanzi amdaka angena kwiyunithi yokuqokelela amanzi amdaka.
