I-Syngas Purification and Refinery Plant

Ukususwa kwe-H2S ne-CO2 kuma-syngas kuwubuchwepheshe obujwayelekile bokuhlanza igesi.Isetshenziswa ekuhlanzweni kwe-NG, igesi yokuguqula i-SMR, i-gasification yamalahle, ukukhiqizwa kwe-LNG ngegesi ye-coke oven, inqubo ye-SNG.Inqubo ye-MDEA yamukelwa ukususa i-H2S ne-CO2.Ngemuva kokuhlanzwa kwe-syngas, i-H2S ingaphansi kuka-10mg / nm 3, i-CO2 ingaphansi kuka-50ppm (inqubo ye-LNG).

● Ubuchwepheshe obuvuthiwe, ukusebenza okulula, ukusebenza okuphephile nokuthembekile,.
● I-reboiler ayidingi umthombo wokushisa wangaphandle wokukhiqiza i-hydrogen kusuka kugesi yemvelo ye-SMR.

(kuthatha ukuhlanzwa kwegesi yemvelo ye-SMR njengesibonelo)
I-syngas ingena ku-reboiler yombhoshongo wokuvuselela ku-170 ℃, bese ipholisa amanzi ngemva kokushintshana kokushisa.Izinga lokushisa lehla laya ku-40 ℃ futhi lingena embhoshongweni we-decarbonization.I-syngas ingena isuka engxenyeni engezansi yombhoshongo, uketshezi lwe-amine lufafazwa ukusuka phezulu, futhi igesi idlula embhoshongweni wokumunca ukusuka phansi kuya phezulu.I-CO2 esegesi iyamuncwa.Igesi ekhishwe yikhabhoni iya enqubweni elandelayo yokukhipha i-hydrogen.Okuqukethwe kwe-CO2 kwegesi ekhishwe yikhabhoni kulawulwa ku-50ppm ~ 2%.Ngemva kokudlula embhoshongweni we-decarbonization, isixazululo esithambile simunca i-CO2 futhi sibe uketshezi olucebile.Ngemuva kokushintshana kokushisa noketshezi oluthambile ekuphumeni kombhoshongo wokuvuselela, uketshezi lwe-amine lungena embhoshongweni wokuvuselela ukuze lukhumulwe, futhi igesi ye-CO2 iya emkhawulweni webhethri ukusuka phezulu kombhoshongo.Isixazululo se-amine sishiswa yi-reboiler ngaphansi kombhoshongo ukuze kukhishwe i-CO2 futhi ibe uketshezi oluthambile.Uketshezi oluthambile luphuma ngaphansi kombhoshongo wokukhiqiza kabusha, ngemva kokucindezelwa bese ludlula esishintshisani sokushisa uketshezi olucebile nesimpofu kanye nesipholile esiwuketshezi oluthambile ukuze luphole, bese lubuyela embhoshongweni wokukhipha ikhabhoni ukuze lumunce igesi eneasidi CO2.
