Ko te Kounga Nui o Haina TEG Dehydration Unit Kaiwhakarato - MDEA desulphurization skid – Rongteng

Whakaahuatanga

Ko te MDEA desulphurization (desulfurization) skid, e kiia ana ko te MDEA sweeting skid, he taputapu matua mo te horoi hau maori, he whakamahana hau maori ranei.

Ko te MDEA desulfurization skid mo te hau maori ka mau tonu i te wa e tino nui ana te whanariki waro o te hau whangai , a ka hiahiatia te tango i te H2S kia whiwhi hau waikawa e tika ana mo te tukatuka tipu a Claus, me etahi atu tikanga ka taea te kowhiria hei tango i te H2S; A, no te tango i te H2S me te tango i te nui o te CO2, ka taea te whakamahi i te MDEA me etahi atu waipiro (penei i te DEA) hei tikanga whakauru amine;

Tukanga

Whai muri i te tangohanga o nga poke totoka me te wai mai i te hau whangai na roto i te whakawehe me te whakawehe tātari, ka whakakorehia te hau kai i roto i te pourewa takirere rererangi. Ko te wairewa Methyl diethanol (MDEA) ka whakamahia hei desulphurizer i roto i te pourewa.

Whai muri i te tango i te iti o te pahuka wai MDEA mai i te hau na roto i te whakawehe purenga maku, ka uru te hau makuku ki roto i te pourewa whakamakuku.

Ka whakamahia te TEG ki te whakamakuku i te hau maori maku i roto i te pourewa ka whakamahia te hau maroke mai i te pourewa whakamakuku. Ka whakamahia te hau maori hei hau taonga mo te kaweake.

Ko te wai nui o te MDEA i roto i te pourewa whakangao kare ka whakaeto ki te tango i te waiwaro me te tātari e nga tātari. Katahi ka whakamahana ma te mamaoa ki te whakahou i te wai MDEA rawakore, ka panaia ki te pourewa desulfurization mo te desulfurization cyclic.

Ko te hau maaori mai i te MDEA taonga nui o te kopa wai ka tangohia e te whakawehe waikawa-wai, ka panaia te otinga MDEA kua wehea ki te pourewa desulfurization. Ko te wai nui o TEG e whakamahia ana i roto i te pourewa whakamaoritanga ka whakamahana ki te whakahou i te otinga TEG rawakore ma te pou whakamahana, te tank hiko me te tātari. Ka panaia ki te pourewa whakamaoritanga mo te whakamaroketanga huringa.

I muri i te werohanga o te hau H2S ki roto i te taika rokiroki hau waikawa i te waahi wehenga o te whakawehe i te wai waikawa, ka whakamahana i roto i te oumu tauhohenga me te tauhohe ki te hau i ngotehia e te compressor hau ki te hanga SO2, ka tauhohe ki te toenga H2S ki te hanga whanariki timatanga, katahi ka whiwhi whanariki i muri i te meangiti.
