Chigadzirwa chechikamu chekubvisa sulfurization chebazi rePetroChina Changqing remafuta mufekitori yedu

Chigadziko chePetroChina Changqing oilfield Branch chine simba rekugadzirisa re40000 Nm3 uye 1.0 MPa.

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

MDEA desulfurization skid Gasi rechisikigo rinogaroshandiswa kana kabhoni sarufa yegasi rekudyisa yakakwira, uye kana H2 yabviswa nenzira yakasarudzwa.₂S inodiwa kuti pave negasi rine acid rakakodzera kugadzirwa kweClaus plant, uye mamwe mamiriro ezvinhu anogona kusarudzwa kubvisa H₂S; Pakubvisa H₂S uye kubvisa huwandu hwakakura hweCO2₂, MDEA nedzimwe alcoholamine (dzakadai seDEA) dzinogona kushandiswa senzira yemixed amine;

Maitiro e Chidzitiro chekubvisa asidhi negesi cheMDEAndeidzi:

Mushure mekunge tsvina yakasimba uye yemvura yabviswa kubva mugasi rekudyisa kuburikidza nemuchina wekuparadzanisa uye wekuparadzanisa mafirita, gasi rekudyisa rinobviswa mudura revharuvhu rinoyangarara. Mhinduro yeMDEA inoshandiswa semuchina wekudyisa mafirita 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 mekubaya H₂Gasi reS rinopinda mutangi rekuchengetera gasi rine acid panzvimbo yekuparadzanisa yeacid water separator, rinopiswa muchoto che reaction uye rinoita zvinoenderana nemhepo inosvutwa neair compressor kuti riumbe SO₂, iyo inopindirana neH yasara₂S inoumba elemental sarufa, uye inobva yawana sarufa mushure mekutonhora.

Gasi rechisikigo mushure mekubviswa kwesulfurization richapinda mu chikamu chekubvisa mvura kubva mumhepo uye zvozoendeswa kufekitori yejenareta kuburikidza nemapaipi.
