Boleng bo Phahameng ba China Natural Gas Processing Skid Exporters - MDEA method decarburization skid bakeng sa lisebelisoa tsa boemo ba khase ea tlhaho - Rongteng

Tlhaloso

Khase ea tlhaho decarburization (decarbonization) skid, ke sesebelisoa se ka sehloohong sa tlhoekiso ea khase ea tlhaho kapa kalafo.

Likahare tsa carbon dioxide maemong a boleng ba khase ea tlhaho ha lia lokela ho feta 3%. 'Me carbon dioxide ka metsing ka mor'a hore tšepe e be le senya se matla haholo. Haeba pH ea boleng e tšoana, karo-karolelano ea acidity ea carbon dioxide le eona e phahame, kahoo tekanyo ea ho bola ea carbon dioxide holim'a tšepe le eona e phahame.

Ka hona, bakeng sa tlhokahalo ea khase ea tlhaho ea decarburization, ho hlokahala hore ho be le phello e matla ea mocheso nakong ea decarburization, kahoo khase ea tlhaho ka mor'a ho futhumatsa mocheso oa mocheso ha o tšoanelehe bakeng sa decarburization ea khase ea tlhaho. Leha ho le joalo, haeba re sa nahane ka lihlahisoa tsa khase ea tlhaho ea decarbonization, empa re amohela mokhoa oa ho arohana ha mocheso o tlaase, o tla lebisa ka ho toba katlehong ea khase ea tlhaho ea decarbonization. Hajoale, ts'ebeliso ea kalafo ea khase ea tlhaho ea decarbonization e ka etsa feela mokhoa oa joala oa ammonia.

Phallo chate

Ho latela litšoaneleho tsa theknoloji ea MDEA, ts'ebetso ea nchafatso ea karolo e ea hlokahala bakeng sa decarbonization ea khase ea tlhaho. Har'a bona, khase ea tlhaho e kenella haholo ka mokelikeli ho tloha ka tlaase, 'me ho kopana le tharollo ea MDEA ho tloha holimo ho ea tlaase ho mokelikeli, empa boholo ba tharollo ea carbon dioxide ka khase ea tlhaho e senyeha. Khase ea tlhaho e hloekisitsoeng e metsi e arotsoe haholo ke tora ea ho monya ebe e pholile, ebe e felloa ke metsi. MDEA e tsoang botebong ba tora ea ho monya e hloka matla ho kenella kalafong ea ho felloa ke metsi, 'me karolo e ka holimo ea tora ea ho monya e kena tora. Ka mor'a ho senyeha, carbon dioxide e nkiloeng e rarolloa ebe e futhumatsoa ke mouoane bohareng ba tora ea tsosoloso. Ke ka tsela ena feela mocheso oa tharollo o ka bolokoang. Ka mor'a hore tharollo ea MDEA e tsoang ka tlaase ho tora e pholile, tharollo e kena ka holim'a ho monya, e le hore e phethe mokhoa oohle oa ho potoloha ha tharollo. Ho phaella moo, e le ho netefatsa ka katleho hore tharollo e ka sebelisoa hape le ho hloekisoa hape, 15% ea tharollo e hlokahalang bakeng sa ho tlosoa ha tharollo. E le ho boloka ts'ebetso ea decarbonization ea khase ea tlhaho, tsamaiso e tla tsosolosoa ka tharollo.

Likarolo tse sebetsang

Ho sebetsa hantle ha decarbonization ka mokhoa oa MDEA ke 99%.
Bakeng sa ho tlosa carbon dioxide (CO2) ho tsoa khase ea phepelo, tharollo ea metsi e nang le amine ea joala ha solvent e kopana le CO2 khase ea phepelo. Tahlehelo e tlase ea khase le tšebeliso e phahameng ea matla. Mokhoa oa amine oa joala o ka boela oa sebelisoa ho tlosa H2S khase ea phepelo.
