MDEA desulphurization skid yekurapa gasi rechisikigo

Tsananguro

Chidziyo cheMDEA chekubvisa sulphurization (desulfurization), chinonziwo MDEA sweeting skid, chinhu chakakosha mukuchenesa gasi rechisikigo kana kugadzirisa gasi rechisikigo.

MDEA desulfurization skid yegasi rechisikigo inogara ichishandiswa kana kabhoni sarufa yegasi rechikafu yakakwira, uye kana kubviswa kweH2S kwakasarudzwa kuti pave negasi rine acid yakakodzera kugadzirwa kweClaus plant, uye mamwe mamiriro anogona kusarudzwa kubvisa H2S; Pakubvisa H2S uye kubvisa huwandu hwakawanda hweCO2, MDEA nedzimwe alcoholamine (senge DEA) dzinogona kushandiswa senzira yekubatanidza amine;

Maitiro

Mushure mekunge tsvina yakasimba uye yemvura yabviswa kubva mugasi rekudya kuburikidza nemuchina wekuparadzanisa uye wekuparadzanisa mafirita, gasi rekudya rinobviswa mudura revharuvhu rinoyangarara. Mhinduro yeMethyl diethanol (MDEA) inoshandiswa se desulphurizer mudura.

Mushure mekubvisa furo diki reMDEA remvura kubva mugasi kuburikidza nemuchina wekuparadzanisa wet cleansing, gasi rechisikigo rakanyorova rinopinda mushongwe yekubvisa mvura mumuviri.

TEG inoshandiswa kunyungudutsa gasi rechisikigo rakanyorova riri mushongwe uye gasi rakaoma rinobva mushongwe yekushaikwa kwemvura rinoshandiswa. Gasi rechisikigo rinoshandiswa segasi rekutengesa zvinhu kunze kwenyika.

Mvura ine MDEA yakawanda iri mu desulfurization tower inobviswa mahydrocarbons yoseferwa nema filters. Zvadaro inopiswa nemhepo kuti igadzirezve mvura isina kunaka ye MDEA, iyo inopombwa kuenda ku desulfurization tower kuti ibude cyclic desulfurization.

Gasi rechisikigo rinobva kuMDEA rine mvura yakawanda rinobviswa ne acid-water separator, uye mhinduro yeMDEA yakaparadzaniswa inopombwa kuenda ku desulfurization tower. Mvura ine TEG yakawanda inoshandiswa mu dehydration tower inopiswa kuti igadzirezve TEG solution isina kunaka kuburikidza ne distillation column, flash tank uye filter. Inopombwa kuenda ku dehydration tower kuti iome cyclic dehydration.

Mushure mekupinza gasi reH2S mutangi rekuchengetera gasi rine acid panzvimbo yekuparadzanisa yeacid water separator, rinopisirwa muchoto che reaction uye rinoita seri nemhepo inosvutwa ne air compressor kuti rigadzire SO2, iyo inobatana neH2S yasara kuti igadzire elemental salfa, uye yozowana salfa mushure mekutonhorera.
