Inqubo yokutholwa kwama-hydrocarbon alula egesini ehambisanayo ezindaweni zikawoyela (2)
3) Uhlelo lwesiqandisi segesi yemvelo
1) Incazelo yenqubo
Ngemva kokuphelelwa amanzi emzimbeni nokuhlunga uthuli, igesi yemvelo ingena endaweni yokushisa ukushisa futhi izinga lokushisa lehla libe ngu-~7 °C ngaphambi kokungena ohlelweni lwesiqandisi se-propane. Izinga lokushisa lehla liye ku -33 ° C ~ ngaphambi kokungena kusihlukanisi sezinga lokushisa eliphansi. Ukubuya kwesigaba segesi kwesihlukanisi sezinga lokushisa eliphansi kanye nesishintshi sokushisa kushisiswe kufika ku-~ 13 °C, futhi isigaba soketshezi singena embhoshongweni we-NGL ngemva kokugingqa.
2) Design nemingcele
Umthamo wokucubungula igesi: 70 × 104Nm3/d
Ingcindezi yokusebenza 3.5MPaG
Izinga lokushisa lokungena lingu-7 ℃
Izinga lokushisa lokukhipha ~ - 33 ℃
4) Uhlelo lombhoshongo we-NGL
1) Incazelo yenqubo
Ama-hydrocarbon aphuma kusihlukanisi sezinga lokushisa eliphansi angena embhoshongweni we-NGL ngemva kokuwohloka. Phezulu kombhoshongo igesi yemvelo ekhishwe ama-hydrocarbon asindayo, futhi phansi kombhoshongo kunama-hydrocarbon asindayo.
2) Design nemingcele
I-NGL tower working pressure 1.0MPa G
5) Isistimu yokugcina i-hydrocarbon esindayo
1) Incazelo yenqubo
Umkhiqizo: NGL
2) Design nemingcele
Ithangi lokugcina le-NGL
Ingcindezi yokusebenza 1.0MPa G
Izinga lokushisa lokuklama 100 ℃
Umthamo 50 m3
6) Isistimu yokugcina indle
1) Incazelo yenqubo
Ukugcinwa kwendle.
2) Design nemingcele
ithangi lokugcina indle
Ingcindezi yokusebenza Ingcindezi evamile
Izinga lokushisa lokuklama ngu-80 ℃
Umthamo 50 m3
Ngaphezu kwezici zobuchwepheshe, iukubuyiselwa kwama-hydrocarbons alula kusuka kugesi ehambisanayo futhi kunezinzuzo zemvelo. Ngokuthola kabusha i-NGL ne-LPG, inani le-methane namanye amagesi abamba ukushisa akhishelwe emkhathini liyehla, okunomthelela emizamweni yokunciphisa ukushintsha kwesimo sezulu. Ngaphezu kwalokho, ukukhulisa ukutholwa kwezingxenye ezibalulekile zegesi ehambisanayo kusiza ekwehliseni ukungcola kanye nokwenza kahle ukusetshenziswa kwemithombo yemvelo.
Sengiphetha, iukubuyiselwa kwe-NGL ne-LPG kusukela kugesi ehlobene ezindaweni zikawoyela kuyinqubo ebucayi engagcini nje ngokungeza inani emfudlaneni wegesi kodwa futhi enomthelela ekuvikelekeni kwamandla kanye nokusimama kwemvelo. Ngokusetshenziswa kobuchwepheshe obuthuthukile obufana nokucubungula i-cryogenic nokumuncwa, imboni iyaqhubeka nokwenza ngcono ukusebenza kahle nokusebenza kahle kweUkubuyiselwa kwe-NGL ne-LPG, ukuqinisekisa ukuthi imithombo ebalulekile ayimoshi nokuthi imithelela yemvelo iyancishiswa.
