Chirongwa ichi chiri muguta reSuining, mudunhu reSichuan, kuChina. Mvura inoyerera inosvika mamiriyoni matatu emakubhiki mita pazuva.
Chidziyo cheMDEA chekubvisa sulphurization (desulfurization), chinonziwo MDEA sweeting skid, chinhu chakakosha mukuchenesa gasi rechisikigo kana kugadzirisa gasi rechisikigo.
MDEA desulfurization skidGasi 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;
Mushure mekunge tsvina yakasimba neyakasviba yabviswa kubva mugasi rekudya kuburikidza nemuchina wekuparadzanisa uye wekuparadzanisa mafirita, gasi rekudya rinobviswa mudura revharuvhu rinoyangarara. Mhinduro yeMDEA inoshandiswa semuchina wekuparadzanisa mafirita mudura. Mushure mekubvisa furo diki reMDEA kubva mugasi kuburikidza nemuchina wekuparadzanisa mafirita, gasi rechisikigo rakanyorova rinopinda mudura remvura inonaya.
TEG inoshandiswa kunyungudutsa gasi rechisikigo rakanyorova riri mushongwe uye gasi rakaoma rinobva mushongwe yekubvisa mvura rinoshandiswa. Gasi rechisikigo rinoshandiswa segasi rinokodzera kutengeswa kunze kwenyika. Mvura ine MDEA yakawanda mushongwe yekubvisa sulfur inobviswa nechiedza kuti ibvise mahydrocarbons uye inosefetwa nemafirita. Zvadaro inopiswa nemhepo kuti igadzirezve mvura isina kunaka ye MDEA, iyo inopombwa kuenda kushongwe yekubvisa sulfurization kuti ibvise 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 muchikamu chekubvisa mvura kubva mumhepondokuzoendeswa ku jenareta yegesi yechisikigo mafekitori emagetsi anosvika mamiriyoni zana emakirowati, ayo anogona kugadzira magetsi anorema makirowati zana emaawa.
