Ukuqokelelana kwegesi yentsimi yeoyile (oko kukuthi, igesi enxulumene neoyile eluhlaza) kunye nobunjineli benkqubo yothutho ngokubanzi kubandakanya: ukuqokelelana kwegesi, ukucutshungulwa kwegesi; Ukuthutha igesi eyomileyo kunye ne-hydrocarbon ekhanyayo; Ukuthutha ioyile eluhlaza ngokutywiniweyo, ukuzinza kweoyile eluhlaza, ukugcinwa kwe-hydrocarbon ekhanyayo, njl.njl.
Ukuqokelelwa kwegesi yentsimi yeoyile
Emva kokuba ioyile ekrwada iphumile emthonjeni weoyile ize ilinganiswe ngumhluzi wemitha, ioyile kunye negesi zithuthwa ziye kwindawo yohluzi yeoyile kunye negesi yesikhululo sokudlulisa ioyile. Igesi ye-oyile yahlulwe kwioyile ekrwada ize ingene kwinethiwekhi yokuqokelela igesi. Ngokubanzi, isikhululo sokuqokelela igesi esizicinezelayo okanye esiqinisayo sakhiwe kwindawo edibeneyo yesityalo sokuvelisa ioyile. Ii-compressors ze-booster ikakhulu zii-compressors ezininzi eziphinda-phindayo zesigaba esinye. Uxinzelelo lokungena lunokudada, kwaye uxinzelelo lokukhupha luxhomekeke kuxinzelelo olungasemva kwenkqubo. Uxinzelelo oluphezulu lokukhupha yi-0.4MPa.
Ukuqokelela nokuthuthwa kweoyile ekrwada kufutshane
Ukuqokelelana kunye nokuthuthwa kweoyile ekrwada ngokuvalekileyo yeyona nto iphambili ekukhupheni i-hydrocarbon ekhanyayo kwioyile ekrwada ngendlela yokuzinzisa ioyile ekrwada, kwaye ikwayenye yeendlela ezibalulekileyo zokunciphisa ukulahleka kweoyile ekrwada.
Kwisikhululo sokuhambisa ioyile, ioyile ekrwada edlula kwi-oyile-gas separator ingena kwi-free water stripper, ize ithunyelwe kwisikhululo sokukhupha amanzi kwioyile ekrwada ngetanki ye-water bearing buffer kunye ne-export heating furnace. Apha, ioyile ekrwada idlula kwi-free water remover, ize ingene kwi-dehydration heating furnace ukuze ifudumale, ize ingene kwi-composite electric dehydrator. Emva kokuphelelwa ngamanzi emzimbeni, ioyile ekrwada ingena kwi-buffer tank (umxholo wamanzi kwioyile ekrwada ungaphantsi kwe-0.5%), ize ipompelwe kwiyunithi yozinziso lweoyile ekrwada, kwaye emva kozinziso, ioyile ekrwada ingena kwi-storage tank ukuze ithunyelwe kwamanye amazwe.
Kwinkqubo evaliweyo yesikhululo sokuhambisa ioyile kunye nesikhululo sokukhupha amanzi emzimbeni, amanzi asimahla akhutshwa kwangaphambili aze axutywe namanzi afakwe kwi-oyile kwindawo apho kusetyenziswa khona ukuze kuncitshiswe ukusetyenziswa kwamandla emveliso.
Ukucutshungulwa kwegesi ye-oyile
Igesi ye-oyile evela kwisikhululo sokuzicinezela ingena kwiyunithi yokupholisa engaphantsi (okanye i-cryogenic), apho icinezelwa khona, iqandiswe ize yahlulwe kunye negesi engavuthiyo evela kwiyunithi yokuzinzisa ioyile eluhlaza ukuze ifumane izinto ezingaphezulu kwe-C3 (okanye i-C2), kwaye igesi eyomileyo ithunyelwa kwamanye amazwe.
Inkqubo yokuqokelela kunye nokuthutha iihydrocarbon ezilula
Ukuqokelela kunye nokuthuthwa kwee-hydrocarbon ezilula kusebenzisa indlela yokuthutha imibhobho, kwaye inkqubo yenziwe ngogcino oluncedisayo, isikhululo sokudlulisa, indawo yokugcina ngokubanzi, isikhululo sokuthumela imitha kunye nenethiwekhi yemibhobho ehambelanayo.
I iyunithi yokubuyisa i-hydrocarbon ekhanyayo ixhotyiswe ngetanki yokugcina, esetyenziselwa ukuphelisa ukuphelelwa ngamanzi emzimbeni, ukulungelelanisa imveliso, isikhuseli sempompo yokuthumela ngaphandle kunye nombhobho wokuthumela ngaphandle ukuqinisekisa imveliso eqhelekileyo okanye ukuvalwa okucwangcisiweyo kweyunithi xa kuthe kwenzeka ingozi. Umthamo wokugcina wetanki yokugcina ngokubanzi yimihla e-1 ukuya kwezi-2 yokuveliswa kwe-hydrocarbon ekhanyayo.
Umsebenzi ophambili we-light hydrocarbon transfer depot kukusebenzisa i-depot ukulungelelanisa ukungalingani phakathi kokuveliswa kwe-light hydrocarbon kunye nokuthunyelwa kwamanye amazwe ngosuku olunye, kunye nokugcina nokucoca ukungcola kwepayipi xa kwenzeka ingozi yepayipi.
Umsebenzi oyintloko wokugcina iihydrocarbon ezikhanyayo ngokubanzi kukusebenzisa itanki yokugcina ukulungelelanisa ukungalingani phakathi kokuveliswa kweehydrocarbon ezikhanyayo kunye nokuthunyelwa kwamanye amazwe, kubandakanya ukuguquguquka kwemveliso yeyunithi yemveliso, ukuguquguquka kwemveliso okubangelwa ngamaxesha ahlukeneyo okugcinwa kweyunithi, ukugcinwa kwesityalo se-ethylene ngaphandle kokugcinwa kwe-ammonia, kwaye intsimi yeoyile kufuneka iqhubeke nokubonelela ngokugcinwa kweehydrocarbon ezikhanyayo ezifunyenwe kwigesi yokutya.
Indawo yokugcina iihydrocarbon ezikhaphukhaphu kunye nesikhululo sokulinganisa ukuthunyelwa kwamanye amazwe ziindawo eziphambili zokukhupha izinto eziluhlaza zehydrocarbon ezingamanzi ezibonelelwa yintsimi yeoyile yesityalo se-ethylene, indawo yokuqokelela iihydrocarbon ezikhaphukhaphu eziveliswa ziiyunithi ezahlukeneyo zokubuyisela iihydrocarbon ezikhaphukhaphu, kunye nendawo yokugcina kunye nokuthutha iihydrocarbon ezikhaphukhaphu.
Inkqubo yokuthumela ngaphandle kunye nokubuyisela igesi eyomileyo
Igesi yentsimi yeoyile iyanyangwa kwaye icutshungulwe emva kokubuyiselwa. Uninzi lwegesi eyomileyo emva kokubuyiselwa kwe-hydrocarbon ekhanyayo ithunyelwa kwizityalo zaseDahua nakwi-methanol njengezinto ezisetyenzisiweyo zamakhemikhali, kwaye inxalenye yegesi eyomileyo ithunyelwa kwisikhululo sokudlulisa ioyile kwintsimi yeoyile njengepetroli yokufudumeza isithando somlilo kunye nebhoyila. Ukubuya kwegesi eyomileyo yinkqubo echaseneyo yokuqokelela igesi. Kwangaxeshanye, enye yegesi eyomileyo ifakwe kwindawo yokugcina igesi ehlotyeni. Iveliswa ebusika ukunciphisa ukunqongophala kobonelelo lwegesi yendalo kunye nemfuno.
Enye yegesi eyomileyo isetyenziselwa ukuvelisa umbane kunye negesi kubemi.
