I-High Quality China Evaporative Crystallizer Factory - I-MDEA desulphurization skid yokwelashwa kwegesi yemvelo - Rongteng

Incazelo

I-MDEA desulphurization (desulfurization) skid, ebizwa nangokuthi i-MDEA sweeting skid, iyithuluzi elibalulekile ekuhlanzeni igesi yemvelo noma ukulungisa igesi yemvelo.

I-MDEA desulfurization skid yegesi yemvelo ihlale yamukelwa lapho i-carbon sulphur yegesi yokuphakelayo iphakeme ngokuqhathaniswa, futhi lapho ukususwa okukhethiwe kwe-H2S kudingekile ukuze kutholwe igesi ene-asidi efanelekile ukucubungula isitshalo sikaClaus, nezinye izimo ezingakhethwa ukususa i-H2S; Lapho ukhipha i-H2S futhi ukhipha inani elikhulu le-CO2, i-MDEA nezinye i-alcoamine (njenge-DEA) zingasetshenziswa njengendlela exubile ye-amine;

Inqubo

Ngemva kokususwa kokungcola okuqinile noketshezi egesini eliphakelayo ngesihlukanisi nesihlukanisi sokuhlunga, igesi yokuphakelayo ikhishwa i-desulphur embhoshongweni we-float valve. Isixazululo seMethyl diethanol (MDEA) sisetshenziswa njenge-desulphurizer embhoshongweni.

Ngemva kokukhipha igwebu elincane le-MDEA eliwuketshezi egesini ngokusebenzisa isihlukanisi sokuhlanza okumanzi, igesi yemvelo emanzi ingena embhoshongweni wokuphelelwa amanzi emzimbeni.

I-TEG isetshenziselwa ukukhipha amanzi egesi yemvelo emanzi embhoshongweni futhi igesi eyomile evela embhoshongweni wokukhipha amanzi emzimbeni iyasetshenziswa. Igesi yemvelo isetshenziswa njengegesi yempahla efanelekile ukuze ithunyelwe ngaphandle.

Uketshezi olucebile lwe-MDEA kumbhoshongo we-desulfurization luyahwamuka ukuze kukhishwe ama-hydrocarbons futhi luhlungwe ngezihlungi. Bese ishiswa ngesitimu ukuze ikhiqize kabusha uketshezi olubi lwe-MDEA, oluphonswa embhoshongweni we-desulfurization ukuze kukhishwe i-cyclic desulfurization.

Igesi yemvelo evela ku-MDEA enothile ye-liquid flash isuswa isihlukanisi samanzi e-asidi, bese isixazululo esihlukanisiwe se-MDEA siphonselwa embhoshongweni we-desulfurization. Uketshezi olucebile lwe-TEG olusetshenziswa embhoshongweni wokukhipha amanzi emzimbeni luyashiswa ukuze lukhiqize kabusha isixazululo se-TEG esingesihle ngekholomu ye-distillation, ithangi le-flash nesihlungi. Iphonswa embhoshongweni wokuphelelwa amanzi emzimbeni ukuze i-cyclic dehydration.

Ngemva kokujova igesi ye-H2S ethangini lokugcina igesi ene-asidi endaweni yokuhlukana yesihlukanisi samanzi ane-asidi, ishiswa kusengaphambili esithandweni somlilo futhi isabela ngomoya omunywa isigaxa somoya ukwenza i-SO2, esabela ne-H2S esele ukwenza isulfure eyisici, bese ithola isulfure ngemva kokupholisa.
