Kounga High China Molecular Dehydration Factory - PSA decarbonization skid mo te pure hau maori – Rongteng

Whakaahuatanga

Ko te whakakorenga hau maori (decarbonization) te paheketanga, he taputapu matua mo te purenga hau maori, te maimoatanga ranei.

Ko te ihirangi o te waro hauhaa i roto i te paerewa kounga hau maori kaua e neke ake i te 3%. Na te hauhā i roto i te wai i muri i te maitai he ha'iriiri tino kaha. Mena he rite te uara PH, he nui ake ano te tauwehenga waikawa o te waro hauhaa, no reira ka teitei ake te tohu waikura o te waro hauhaa ki runga maitai.

Ko te Pressure swing adsorption (PSA) he hangarau hou e whakamahia ana hei wehe i te ranunga hau i roto i te hangarau wehenga adsorption. Ka whakatauritea ki te tikanga whakauru matū tuku iho, he tino ataahua te hangarau PSA mo te tango me te whakaora i te H2S me te CO2 mai i te hau maori, a kei te kaha te whakawhanake.

Ko te hangarau wehenga hau PSA nga painga o te mahi ngawari, te iti o te pehanga mate, te matewai i te wa e tango ana i te CO2, te iti o te hau o te hau me te wai, ka taea e nga hua te whakatutuki i nga whakaritenga o te kaweake hau. Ka taea te whakamahi i te PSA mo te kukū CO2 me te whakakore i te weranga i roto i te hau maori.

Tūtohi rere

I mahia te urunga i raro i te pehanga me te whakaheke i raro i te pehanga iti. No te mea he poto te huringa adsorption me te wera adsorption e kore e taea te whakakore i te waa, ka taea te whakamahi mo te whakaheke. Na reira, he iti noa te huringa o te pāmahana o te moenga adsorption i puta mai i te wera adsorption me te wera desorption, ka taea te kii he mahi hauwaro. Mahi moenga adsorption whakaritea kotahi, ahakoa he pāmahana piu adsorption pehanga piu adsorption ranei, no te mea e hiahia ana te adsorbent ki te kia regenerated, he mokowhiti te adsorption. I roto i te ahumahi, e rua, neke atu ranei nga moenga adsorption e whakamahia ana, kia mau tonu ai te whakaurunga me te whakahou o te moenga adsorption (i roto ranei i te huringa hurihanga), hei whakarite i te haere tonu o te tukanga adsorption katoa.

Nga waahanga mahi

Ko te kaha o te pehanga swing adsorption decarbonization skid he 90%.CO2 ka taea te wehe ma te huringa pehanga me te adsorption tinana, kaore he tauhohenga matū. I tua atu i te tango CO2, ka whakamahia te hangarau PSA ki te whakaora me te purenga o H2, CH4, CO, CO2 me etahi atu hau.
