I-MDEA desulphurization skid yonyango lwegesi yendalo

Inkcazo

I-MDEA desulphurization (desulfurization) skid, ekwabizwa ngokuba yi-MDEA sweeting skid, sisixhobo esibalulekileyo ekucoceni igesi yendalo okanye ekulungiseni igesi yendalo.

I-MDEA desulfurization skid yegesi yendalo isoloko isetyenziswa xa i-carbon sulphur yegesi yokutya iphezulu, kwaye xa kufuneka ukususwa okukhethekileyo kwe-H2S ukuze kufunyanwe igesi ye-asidi efanelekileyo yokucubungula izityalo zeClaus, kunye nezinye iimeko ezinokukhethwa ukususa i-H2S; Xa kususwa i-H2S kunye nokususwa kwesixa esikhulu se-CO2, i-MDEA kunye nezinye i-alcoholamine (ezifana ne-DEA) zingasetyenziswa njengendlela ye-mixed amine;

Inkqubo

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 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 igesi ye-H2S kwitanki yokugcina igesi ye-asidi kwindawo yokwahlulahlula amanzi e-asidi, iyatshiswa kwi-response oven ize iphendulane nomoya ofunxwa yi-air compressor ukuze yenze i-SO2, ethi iphendulane ne-H2S eseleyo ukuze yenze i-elemental sulfur, ize ifumane i-sulfur emva kokuba ipholile.
