Syngas Purification and Refinery Plant

wharangi_ahurea

Ko te tango i te H2S me te CO2 mai i te syngas he hangarau horoi hau.Kei te whakamahia i roto i te purenga o NG, SMR reforming hau, waro hau, LNG production ki te hau oumu coke, SNG tukanga.Ka whakamahia te tukanga MDEA hei tango i te H2S me te CO2.I muri i te purenga o te syngas, he iti ake te H2S i te 10mg / nm 3, he iti iho te CO2 i te 50ppm (te tukanga LNG).

Nga Ahuatanga Hangarau

● Hangarau pakeke, mahi ngawari, mahi haumaru me te pono,.
● Karekau e hiahiatia e te reboiler te puna wera o waho mo te hanga hauwai mai i te hau maori SMR.

Tukanga Hangarau

(te tango i te purenga hau SMR hau maori hei tauira)
Ka uru nga syngas ki te reboiler o te pourewa whakaora i te 170 ℃, ka whakamatao te wai i muri i te whakawhiti wera.Ka heke te pāmahana ki te 40 ℃, ka uru ki te pourewa decarbonization.Ka uru mai nga syngas mai i te pito o raro o te pourewa, ka rehuhia te wai amine mai i runga, ka haere te hau i roto i te pourewa absorption mai i raro ki runga.Ko te CO2 i roto i te hau ka mimiti.Ka haere te hau warowaiha ki te tukanga e whai ake nei mo te tangohanga hauwai.Ko te ihirangi CO2 o te hau decarbonized e whakahaerehia ana i te 50ppm ~ 2%.Whai muri i te haere i roto i te pourewa decarbonization, ka mimiti te wairewa kikokore i te CO2 ka tino wai.I muri i te whakawhitinga wera me te wai hiroki i te putanga o te pourewa whakaora, ka uru te wai amine ki te pourewa whakaora mo te tarai, ka haere te hau CO2 ki te rohe o te pākahiko mai i te tihi o te pourewa.Ka whakamahana te otinga amine e te reboiler i raro o te pourewa ki te tango CO2 ka waiho hei wai hiroki.Ko te wai hiroki ka puta mai i raro o te pourewa whakahou, i muri i te pehanga katahi ka haere i roto i te kaitahuri wera wai rawa me te rawakore me te whakamatao wai hiroki ki te whakamatao, ka hoki ki te pourewa decarbonization ki te tango i te hau waikawa CO2.

Nga Ahuatanga Hangarau

Rahi tipu NG, Syngas ranei 1000~200000 Nm³/h
Te whakakore warowaiha CO₂≤20ppm
whakawhanaungatanga H₂S≤5ppm
Te pehanga 0.5~15 MPa (G)
