Inkqubo yokubuyisa ii-hydrocarbons ezikhanyayo kwigesi enxulumene nayo kwiindawo zeoyile (1)
I ukubuyiswa kwee-hydrocarbons ezikhanyayo ukusuka kwigesi enxulumeneyo kwiindawo zeoyile yinkqubo ebalulekileyo kwishishini leoyile negesi. Igesi enxulumeneyo, edla ngokufumaneka ecaleni kweoyile ekrwada, iqulethe izinto ezixabisekileyo ezifana nolwelo lwegesi yendalo (NGL) kunye negesi yepetroleum enyibilikisiweyo (LPG). Ukubuyisa ezi hydrocarbons zikhanyayo akupheleli nje ekunyuseni ixabiso lomjelo wegesi kodwa kunceda ekunciphiseni ukukhutshwa kwegesi ebangela ubushushu. Kweli nqaku, siza kuhlola ukubaluleka kokubuyiswa kwe-NGL kunye ne-LPG kwigesi enxulumeneyo kunye nobuchwepheshe obubandakanyekayo kule nkqubo.
Ukufunyanwa kwe-NGL kwigesi enxulumene nayo kubandakanya ukwahlulwa kunye nokutsalwa kwezinto ezimanzi zegesi yendalo ezifana ne-ethane, i-propane, kunye ne-butane. Ezi zinto zinexabiso elikhulu kwezorhwebo kwaye zisetyenziswa njengezondlo zezityalo ze-petrochemical, kunye nemveliso yeplastiki, irabha yokwenziwa, kunye nezinye iimveliso zoshishino. I-NGL evela kwigesi enxulumene nayo kubalulekile ekuphuculeni amandla oqoqosho lomjelo wegesi nokunciphisa inkcitho yezixhobo ezixabisekileyo.
Inkcazo emfutshane yenkqubo yile:
1) Inkqubo yokuxuba nokukhulisa igesi yendalo
1) Inkcazo yenkqubo
Igesi yokufunxa icinezelwa ukuya kwi-0.3 MPaG ize ixutywe nomsinga woxinzelelo oluphantsi ize icinezelwe ukuya kwi-3.9 MPaG. Umsinga oxutyiweyo emva koko uxutywa noxinzelelo oluphezulu uze ungene kwisixhobo esisezantsi.
2) Iiparamitha zoyilo
Umthamo wokucubungula igesi yokutya:
Uxinzelelo Oluphezulu: 12500 Nm3/h;
Uxinzelelo oluphantsi: 16166.7 Nm3/h;
2) Inkqubo yokuphelelwa ngamanzi kwigesi yendalo
1) Inkcazo yenkqubo
Ubukho bomswakama kwigesi yendalo budla ngokuba nemiphumo emibi kakhulu: umswakama kunye negesi yendalo zinokwenza ii-hydrate okanye umkhenkce ukuvala imibhobho phantsi kweemeko ezithile.
Ukuphelelwa ngamanzi emzimbeni ngegesi yendalo kusebenzisa indlela yokufunxa amanzi ngesihluzo semolekyuli. Ekubeni isihluzo semolekyuli sinokukhetha okunamandla kokufunxa amanzi kunye neempawu eziphezulu zokufunxa amanzi phantsi koxinzelelo oluphantsi lomphunga wamanzi, esi sixhobo sisebenzisa isihluzo semolekyuli se-4A njengesihluzo sokufunxa amanzi emzimbeni.
Le yunithi isebenzisa inkqubo yeenqaba ezimbini ukufunxa umswakama, isebenzisa indlela ye-TSA ukuhlalutya umswakama ofunxwa kwi-seeve ye-molecular, kwaye isebenzisa indlela ye-condensation ukufunxa nokwahlula umswakama ofunxwa kwi-adsorbent.
