Bafani ba Setsi sa Phekolo ea Khase ea Tlhaho ea Boleng bo Phahameng ba Chaena - PSA decarbonization skid - 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 boleng ba PH bo tšoana, karo-karolelano ea asiti ea carbon dioxide le eona e phahame, kahoo tekanyo ea ho bola ea carbon dioxide holim'a tšepe le eona e phahame.

Pressure swing adsorption (PSA) ke theknoloji e ncha e sebelisoang ho arola motsoako oa khase ho theknoloji ea karohano ea adsorption. Ha ho bapisoa le mokhoa o tloaelehileng oa ho monya lik'hemik'hale, theknoloji ea PSA e khahleha moruong bakeng sa ho tlosoa le ho hlaphoheloa ha H2S le CO2 khase ea tlhaho, 'me e ntse e ntlafatsoa ka matla.

Theknoloji ea karohano ea khase ea PSA e na le melemo ea ts'ebetso e bonolo, tahlehelo e tlase ea khatello, ho felloa ke metsi 'meleng ha o ntse o tlosa CO2, phoka e tlaase ea khase e hloekisitsoeng le metsi,' me lihlahisoa li ka finyella litlhoko tsa ho romela ntle ho khase. PSA e ka sebelisoa bakeng sa mahloriso a CO2 le ho khetha desulfurization ka khase ea tlhaho.

Adsorption e ne e etsoa tlas'a khatello 'me desorption e ne e etsoa tlas'a khatello e fokotsehileng. Hobane potoloho ea adsorption e khuts'oane 'me mocheso oa adsorption o ke ke oa qhaloa ka nako, o ka sebelisoa bakeng sa desorption. Ka hona, mocheso oa bethe ea adsorption e bakoang ke mocheso oa adsorption le mocheso oa desorption o na le phetoho e fokolang, e ka nkoang e le mokhoa oa isothermal. Ts'ebetso e le 'ngoe e tsitsitseng ea adsorption, ekaba ke mocheso oa ho swing adsorption kapa khatello ea swing adsorption, hobane adsorbent e hloka ho nchafatsoa, ​​adsorption e ea nako le nako. Ka indasteri, ho sebelisoa libethe tse peli kapa ho feta tsa adsorption, e le hore papatso le nchafatso ea bethe ea adsorption li etsoa ka tsela e fapaneng (kapa ka ho latellana), ho netefatsa hore ts'ebetso eohle ea adsorption e tsoela pele.

Likarolo tse sebetsang

Bokhoni ba khatello ea khatello ea adsorption decarbonization skid ke 90%.CO2 e ka aroloa ke phetoho ea khatello le ho ba le ponahalo ea 'mele, ntle le karabelo ea lik'hemik'hale. Ntle le ho tlosoa ha CO2, theknoloji ea PSA e sebelisoa haholo ho tsosolosa le ho hloekisa H2, CH4, CO, CO2 le likhase tse ling.
