Umkhiqizo weyunithi yokususa i-sulfurization wegatsha likaPetroChina Changqing elisefektri yethu

Iyunithi yokususa i-sulfurization yegatsha likaPetroChina Changqing oilfield inamandla okucubungula angu-40000 Nm3 kanye no-1.0 MPa.

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

i-MDEA desulfurization skid igesi yemvelo isetshenziswa njalo lapho igesi yokudla ephekiwe inesibabule esiphezulu, futhi lapho kususwa i-H ngokukhetha.₂I-S iyadingeka ukuze kutholakale igesi ye-asidi efanele ukucutshungulwa kwesitshalo se-Claus, kanye nezinye izimo ezingakhethwa ukususa i-H₂S; Uma kususwa u-H₂S kanye nokususa inani elikhulu le-CO2₂, i-MDEA kanye nenye i-alcoholamine (njenge-DEA) ingasetshenziswa njengendlela ye-mixed amine;

Inqubo ye I-MDEA acid gas removal skidyilezi:

Ngemva kokuba ukungcola okuqinile noketshezi kususiwe kugesi yokuphakelayo ngokusebenzisa isihlukanisi kanye nesihlukanisi sesihlungi, igesi yokuphakelayo iyasuswa esibabuleni embhoshongweni wevalvu entantayo. Isixazululo se-MDEA sisetshenziswa njenge-desulfurizer embhoshongweni.

Ngemva kokususa inani elincane le-MDEA liquid foam kusuka kugesi ngokusebenzisa isihlukanisi sokuhlanza okumanzi, igesi yemvelo emanzi ingena embhoshongweni wokuphelelwa amanzi.

I-TEG isetshenziselwa ukumunca igesi yemvelo emanzi embhoshongweni kanti kusetshenziswa igesi eyomile evela embhoshongweni wokuphelelwa amanzi. Igesi yemvelo isetshenziswa njengegesi yempahla efanelekile yokuthunyelwa kwamanye amazwe.

Uketshezi olucebile lwe-MDEA embhoshongweni wokususa i-sulfur luyashiswa nge-flash ukuze kususwe ama-hydrocarbon bese luhlungwa ngezihlungi. Bese lufudunyezwa ngomusi ukuze kuphinde kukhiqizwe uketshezi lwe-MDEA olubi, olupompelwa embhoshongweni wokususa i-sulfur ukuze kususwe i-sulfurization nge-cyclic.

Igesi yemvelo evela ku-MDEA rich liquid flash isuswa yisihlukanisi samanzi ane-acid, bese isixazululo se-MDEA esihlukanisiwe sipontshwa siye embhoshongweni wokususa i-sulfurization. Uketshezi olune-TEG olusetshenziswa embhoshongweni wokususa i-dehydration luyashiswa ukuze luphinde luvuselele isixazululo se-TEG esibi ngokusebenzisa ikholomu yokuhluza, ithangi le-flash kanye nesihlungi. Ipontshwa iye embhoshongweni wokususa i-dehydration ukuze kuphuze i-cyclic dehydration.

Ngemva kokujova i-H₂Igesi i-S ingena ethangini lokugcina igesi ye-asidi endaweni yokuhlukanisa yesihlukanisi samanzi e-asidi, ishiswa esithandweni sokusabela bese isabela nomoya odonswa yi-compressor yomoya ukuze yakhe i-SO₂, esabela ne-H esele₂I-S ukwakha isibabule esiyisisekelo, bese ithola isibabule ngemva kokupholisa.

Igesi yemvelo ngemva kokususwa kwesibabule izongena iyunithi yokuphelelwa amanzi emzimbeni ngegesi bese ithuthwa iyiswe esitshalweni sokukhiqiza amagesi ngamapayipi.
