Intshayelelo ye iyunithi yokwenza igesi yendalo ibe mnandi
Emva kokuba ukungcola okuqinileyo nolwelo kususiwe kwigesi yokuphakelwa ngokusebenzisa isihluzi kunye nesihluzi, igesi yokuphakelwa iyasuswa kwinqaba yevalvu edadayo. Isisombululo seMethyl diethanol (MDEA) sisetyenziswa njenge-desulphurizer 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 sisahluli-manzi esine-asidi, kwaye isisombululo se-MDEA esahlulweyo sipompelwa kwi-desulfurization tower.
Ulwelo olutyebileyo lwe-TEG olusetyenziswa kwinqaba yokuphelelwa ngamanzi emzimbeni luyafudunyezwa ukuze luphinde luvelise isisombululo se-TEG esibi ngokusebenzisa ikholamu yokunyibilikisa, itanki yeflash kunye nesihluzi. Lupompelwa kwinqaba yokuphelelwa ngamanzi emzimbeni ukuze lupheliswe ngamanzi emzimbeni nge-cyclic.
Emva kokufaka inaliti ye-H2Igesi ye-S (igesi ye-S)ukususwa kwe-sulfide kwigesi yendalo）Ingena kwitanki yokugcina igesi ye-asidi kwindawo yokwahlulwa kwesahluli samanzi se-asidi, itshiswa kwi-response oven ize iphendulane nomoya ofunxwa yi-air compressor ukuze yenze i-SO2, esabela kwi-H eseleyo2I-S yenza i-elemental sulfur, ize ifumane i-sulfur emva kokuba ipholile. Ngale ndlela, singayigqiba inkqubo Ukususwa kwe-H2S kwigesi yendalo.
