Inqubo yokubuyisa ama-hydrocarbon alula avela kugesi ehlobene nawo emasimini kawoyela (1)
I ukubuyiselwa kwama-hydrocarbon alula kusuka kugesi ehlobene emikhakheni kawoyela kuyinqubo ebalulekile embonini kawoyela negesi. Igesi ehlobene, evame ukutholakala eceleni kukawoyela ongahluziwe, iqukethe izingxenye ezibalulekile njengegesi yemvelo (NGL) kanye negesi kaphethiloli encibilikisiwe (LPG). Ukubuyisa lawa ma-hydrocarbon alula akugcini nje ngokukhulisa inani lomsinga wegesi kodwa futhi kusiza ekunciphiseni ukukhishwa kwegesi ebamba ukushisa. Kulesi sihloko, sizohlola ukubaluleka kokubuyiselwa kwe-NGL kanye ne-LPG kusuka kugesi ehlobene kanye nobuchwepheshe obuhilelekile kule nqubo.
Ukubuyiselwa kwe-NGL kusuka kugesi ehlobene kuhilela ukuhlukaniswa nokukhishwa koketshezi lwegesi yemvelo njenge-ethane, i-propane, ne-butane. Lezi zingxenye zinenani elikhulu kwezentengiselwano futhi zisetshenziswa njengezinto zokudla zezitshalo ze-petrochemical, kanye nokukhiqizwa kwepulasitiki, irabha yokwenziwa, neminye imikhiqizo yezimboni. I-NGL evela kugesi ehlobene kubalulekile ekukhuliseni amandla ezomnotho omfudlana wegesi kanye nokunciphisa ukumoshwa kwezinsiza ezibalulekile.
Incazelo emfushane yenqubo yile:
1) Uhlelo lokuxuba nokukhulisa igesi yemvelo
1) Incazelo yenqubo
Igesi ephakelayo icindezelwa ibe yi-0.3 MPaG bese ixutshwa nomsinga ophansi bese icindezelwa ibe yi-3.9 MPaG. Umsinga oxubile ube usuxutshwa nomsinga ophakeme bese ungena kudivayisi engezansi komsinga.
2) Amapharamitha okuklama
Umthamo wokucubungula igesi lokuphakelayo:
Ukucindezela Okuphezulu: 12500 Nm3/h;
Ukucindezela Okuphansi: 16166.7 Nm3/h;
2) Uhlelo lokuphelelwa amanzi emzimbeni ngegesi yemvelo
1) Incazelo yenqubo
Ukuba khona komswakama kugesi yemvelo kuvame ukubangela imiphumela emibi kakhulu: umswakama kanye negesi yemvelo kungakha ama-hydrate noma iqhwa ukuvimba amapayipi ngaphansi kwezimo ezithile.
Ukuphelelwa amanzi emzimbeni ngegesi yemvelo kusebenzisa indlela yokumunca isihlungi sama-molecule. Njengoba isihlungi sama-molecule sinokukhetha okunamandla kokumunca kanye nezici zokumunca okuphezulu ngaphansi kwengcindezi ephansi yomhwamuko wamanzi, le divayisi isebenzisa isihlungi sama-molecule esingu-4A njengesihlungi sokumunca amanzi emzimbeni.
Le yunithi isebenzisa inqubo enemibhoshongo emibili ukuze imunce umswakama, isebenzisa indlela ye-TSA ukuhlaziya umswakama ofakwe ku-seeve yama-molecule, futhi isebenzisa indlela yokuminza ukuze ihlanganise futhi ihlukanise umswakama okhishwe ku-adsorbent.
2) Amapharamitha okuklama
Umthamo wokucubungula igesi yokuphakelayo 70 × 104 I-Nm3/d
Ingcindezi yokungenisa 3.5MPaG
Izinga lokushisa lokumunca 35 ℃
Ingcindezi yokuvuselela kabusha engu-3.5MPaG
Izinga lokushisa lokuvuselelwa kabusha ~260 ℃
Uwoyela oshisayo womthombo wokushisa ovuselelayo
