Iyunithi yokususa i-sulfurization yeSebe le-oyile lasePetroChina Changqing inomthamo wokucubungula we-40000 Nm3 kunye ne-1.0 MPa.
I-MDEA desulphurization (desulfurization) skid, ekwabizwa ngokuba yi-MDEA sweeting skid, sisixhobo esibalulekileyo ekucoceni igesi yendalo okanye ekulungiseni igesi yendalo.
I-MDEA desulfurization skid igesi yendalo isoloko isetyenziswa xa i-carbon sulfur yegesi yokutya iphezulu, kwaye xa kususwa ngokukhetha i-H22I-S iyadingeka ukuze kufunyanwe igesi ye-asidi efanelekileyo yokucubungula izityalo zeClaus, kunye nezinye iimeko ezinokukhethwa ukususa i-H2S; Xa kususwa u-H2S kunye nokususa inani elikhulu le-CO22, i-MDEA kunye nezinye i-alcoholamine (ezifana ne-DEA) zingasetyenziswa njengendlela ye-mixed amine;
Inkqubo ye I-MDEA acid gas removal skidzezi:
Emva kokuba ukungcola okuqinileyo nolwelo kususiwe kwigesi yokuphakelwa ngokusebenzisa isihluzi kunye nesihluzi, igesi yokuphakelwa iyasuswa kwinqaba yevalvu edadayo. Isisombululo se-MDEA sisetyenziswa njenge-desulfurizer kwinqaba.
Emva kokususa i-MDEA liquid foam encinci kwigesi ngokusebenzisa isahluli sokucoca amanzi, igesi yendalo emanzi ingena kwinqaba yokuphelelwa ngamanzi emzimbeni.
I-TEG isetyenziselwa ukufunxa igesi yendalo emanzi ekwinqaba kwaye kusetyenziswa igesi eyomileyo evela kwinqaba yokufunxa amanzi. Igesi yendalo isetyenziswa njengegesi yempahla efanelekileyo yokuthunyelwa kwamanye amazwe.
Ulwelo olutyebileyo lwe-MDEA kwinqaba yokukhupha i-sulfurization luyakhutshwa nge-flash ukuze kususwe ii-hydrocarbons kwaye luhluzwe ngezihluzi. Emva koko lufudunyezwa ngumphunga ukuze kuphinde kuvele ulwelo olubi lwe-MDEA, olupompelwa kwinqaba yokukhupha i-sulfurization ukuze kukhutshwe i-cyclic desulfurization.
Igesi yendalo evela kwi-MDEA rich liquid flash isuswa ngumhluzi wamanzi ane-asidi, kwaye isisombululo se-MDEA esahlulweyo sipompelwa kwi-desulfurization tower. Ulwelo olune-TEG rich olusetyenziswa kwi-dehydration tower luyafudunyezwa ukuze kuphinde kuvele isisombululo se-TEG esibi ngokusebenzisa ikholamu yokunyibilikisa, itanki ye-flash kunye nesihluzi. Ipompelwa kwi-dehydration tower ukuze kupheliswe ukuphelelwa ngamanzi emzimbeni nge-cyclic dehydration.
Emva kokufaka inaliti ye-H2Igesi ye-S ingena kwitanki yokugcina igesi ye-asidi kwindawo yokwahlulahlula amanzi e-asidi, itshiswa kwi-oven yokusabela kwaye isabela nomoya ofunxwa yi-compressor yomoya ukuze yenze i-SO2, esabela kwi-H eseleyo2I-S yenza i-elemental sulfur, ize ifumane i-sulfur emva kokuba ipholile.
Igesi yendalo emva kokususwa kwe-sulfurization iya kungena kwi- iyunithi yokuphelisa amanzi emzimbeni ngegesi emva koko ithuthwa iye kwisityalo sejenereyitha ngemibhobho.
