I-Skid Yokuthambisa Igesi Yemvelo

Isingeniso

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

Iyunithi yokususa i-sulfurization yegesi yemvelo ye-MDEA ihlala isetshenziswa lapho i-carbon sulfur yegesi yokudla iphezulu kakhulu, futhi lapho kususwa i-H ngokukhetha₂I-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 ingasetshenziswa njengendlela ye-mixed amine;

Njengamanje, ubuchwepheshe obuyinhloko bokususa i-sulfurization obusetshenziswa ekukhiqizweni kwezimboni ekhaya nakwamanye amazwe yilokhu: ukususa i-sulfurization eyomile (ebonakalayo), ukususa i-sulfurization yezinto eziphilayo kanye nokususa i-sulfurization emanzi.

Ukususa i-sulfurization emanzini kuhlanganisa indlela yokumunca kanye nendlela yoku-oxidation emanzini. Indlela yokumunca amakhemikhali, emelelwa ukumunca i-alcohol amine, isetshenziswe kabanzi embonini. I-hydrogen sulfide kugesi idluliselwa esigabeni soketshezi ukuze ihlanze igesi.

Ubuchwepheshe bokususa i-sulfurization

Ubuchwepheshe bokususa i-sulfurization yezinto eziphilayo, esimweni se-micro oxygen, bungaguqula i-hydrogen sulfide ibe yi-elemental sulfur, kodwa ubuchwepheshe bokususa i-sulfurization yezinto eziphilayo abukavuthwa okwamanje.

Ubuchwepheshe bokususa i-sulfurization eyomile buhlanganisa indlela ye-iron oxide, indlela ye-activated carbon, indlela yesihlungo sama-molecule, indlela yokushintshana kwama-ion, indlela yokuhlukanisa i-membrane, indlela ye-biochemical, njll. njengamanje, ubuchwepheshe be-PSA eyomile busetshenziswa kakhulu ekwelashweni kokususa i-sulfurization yegesi yemvelo emincane embonini, okulawulwa ngokuphelele yikhompyutha, ukusebenza okuzenzakalelayo, kanye nokususwa okuzenzakalelayo kombhoshongo wamaphutha, ukuze kufezwe ukusebenza okuphephile kwesikhathi eside.

izindlela zokususa i-sulfurization

I-hydroxide yensimbi e-Amorphous (inqubo eyomile). Izici: inezici zokunemba okuphezulu kwe-desulfurization, umthamo ophezulu we-sulfur, amandla amahle kanye nokunganakekelwa. Isetshenziswa kabanzi ekususweni kwe-hydrogen sulfide kugesi yemvelo, igesi yokwenziwa, i-biogas, igesi yamalahle, i-methane yamalahle kanye nezinto ezahlukahlukene eziqukethe i-sulfur yamakhemikhali; I-amorphous hydroxyl oxidation desulfurization iyindlela yokususa i-sulfurization yokusabela, engakwazi ukulawula ukujula kwe-desulfurization. Kuyinqubo enhle ye-desulfurization. Ngokugcwala kwe-desulfurizer kanye nokungena kombhoshongo we-desulfurization, umphumela we-desulfurization uzoncipha kakhulu, futhi okuqukethwe kwe-hydrogen sulfide kugesi yemvelo ehlanziwe kuzokhuphuka kakhulu, ngakho-ke kuyadingeka ukufaka esikhundleni se-desulfurizer ngesikhathi.
