    Incazelo

    I-skid yegesi yemvelo (i-decarbonization), iyithuluzi elibalulekile ekuhlanzeni noma ekwelapheni igesi yemvelo.

    Okuqukethwe kwe-carbon dioxide kuzinga lekhwalithi yegesi yemvelo akufanele kube ngaphezu kuka-3%. Futhi i-carbon dioxide emanzini ngemva kokuba insimbi ine-corrosive enamandla kakhulu. Uma inani le-pH lifana, isilinganiso se-acidity ye-carbon dioxide nayo iphakeme, ngakho izinga lokugqwala kwe-carbon dioxide ensimbi nalo liphakeme.

    Ngakho-ke, ngesidingo segesi yemvelo decarburization, kuyadingeka ukuthi kube nomthelela oshisayo oqinile ohlelweni lwe-decarburization, ngakho-ke igesi yemvelo ngemuva kokwelashwa kokushisa kwe-humidification ayifanele ukuchithwa kwegesi yemvelo. Kodwa-ke, uma singacabangi ngemikhiqizo ye-decarbonization yegesi yemvelo, kodwa samukele indlela yokuhlukaniswa kwezinga lokushisa eliphansi, kuzoholela ngokuqondile ekusebenzeni kahle kwegesi yemvelo decarbonization. Njengamanje, ukusetshenziswa kokwelashwa kwegesi yemvelo ye-decarbonization kungenza kuphela indlela ye-ammonia yotshwala.

    Ishadi eligelezayo

    Ngokwezici zobuchwepheshe be-MDEA, inqubo yokuvuselela ingxenye iyadingeka ukuze kukhishwe igesi yemvelo. Phakathi kwazo, igesi yemvelo ngokuyinhloko ingena ku-absorber isuka phansi, futhi ithintana nesisombululo se-MDEA kusukela phezulu kuya phansi ku-absorber, kodwa iningi lesisombululo se-carbon dioxide egesi yemvelo i-decarbonized. Igesi yemvelo ehlanzekile emanzi ihlukaniswa ikakhulukazi umbhoshongo wokumuncwa futhi ipholile, bese iphelelwa amanzi. I-MDEA esuka phansi kombhoshongo wokumuncwa idinga amandla ukuze ingene ekwelashweni kokuphelelwa amanzi emzimbeni, futhi ingxenye engenhla yombhoshongo wokumuncwa ingena embhoshongweni. Ngemuva kokuwohloka, i-carbon dioxide emuncwe iyaxazululwa futhi ishiswe ngesitimu phakathi kombhoshongo wokuvuselela. Kungale ndlela kuphela izinga lokushisa lesisombululo lingagcinwa. Ngemuva kokuthi isisombululo se-MDEA esivela phansi kombhoshongo sipholile, isisombululo singena phezulu kokumuncwa, ukuze kuqedelwe yonke inqubo yokujikeleza kwesisombululo. Ukwengeza, ukuze kuqinisekiswe ngempumelelo ukuthi isisombululo singaphinda sisetshenziswe futhi sihlanzwe futhi, i-15% yesisombululo iyadingeka ukuze kususwe isisombululo. Ukuze kugcinwe inqubo yokukhipha ikhabhoni yegesi yemvelo, uhlelo luzovuselelwa ngesixazululo.

    Izici ezisebenzayo

    Ukusebenza kahle kwe-decarbonization ngendlela ye-MDEA ngama-99%.
    Ukuze kukhishwe i-carbon dioxide (CO2) kugesi ephakelayo, isixazululo esinamanzi esine-alcohol amine njengoba isincibilikisi sihlangana ne-CO2 kugesi yokuphakelayo. Ukulahleka kwegesi okuphansi kanye nokusetshenziswa kwamandla okuphezulu. Indlela ye-alcohol amine ingasetshenziswa futhi ukususa i-H2S kwigesi yokudla.
