IInkqubo yaseBenfieldlilitye lembombo kushishinoukucocwa kwegesi, eyamkelwa ngokubanzi kwizityalo zeekhemikhali ukususa i-carbon dioxide (CO2) kunye ne-hydrogen sulfide (H2S) kwimifudlana yegesi, iqinisekisa iziphumo eziphakamileyo zokucoceka kwezicelo kwi-ammonia synthesis, ukuveliswa kwe-hydrogen, kunye nokulungiswa kwegesi yendalo. Ulawulo oluchanekileyo phezu koxinzelelo lwesi sisombululo sokukhuhla lubalulekile ukukhusela imingeni yokusebenza efana nokukhupha amagwebu, ukunciphisa ukusebenza kakuhle, okanye ukubola kwezixhobo.Iimitha zoxinaniso lwe-potassium carbonate ngaphakathikwayeabahlalutyi be-concentration ye-potassium carbonate engaphakathiukubonelela ngesisombululo soguqulo ngokubonelela ngokuqhubekayo, ukubekwa kweliso kwexesha lokwenyani kumanqanaba e-K2CO3 kunye ne-potassium bicarbonate (KHCO3), okuvumela abaqhubi ukuba basebenzise ngokupheleleyoinkqubo yokucoca igesikunye nokuzuza ukonga iindleko ezibalulekileyo.
Esi sikhokelo esibanzi siphonononga ubuxhakaxhaka beBenfield Inkqubo yokususwa kwegesi yeasidi, kunye neenzuzo zabo kumashishini afanaizityalo zokuvelisa i-ammonia,izityalo zokuvelisa i-hydrogen,amaziko okulungisa igesi yendalo,izityalo zepetrochemical,izityalo zokunciphisa intsimbi ngqo, kwayeizityalo zamalahle ezigasification. Ngokudibanisa ezi zixhobo zihambele phambili, abaqhubi bemizi-mveliso banokuphucula ukusebenza kakuhle, baqinisekise ukuthotyelwa kwemigaqo engqongqo, kwaye banikezele ngemveliso engaguqukiyo, ekumgangatho ophezulu werhasi.
IKhemistri kunye neeMechanics zeNkqubo yeBenfield
IInkqubo yaseBenfield, ephuhliswe yi-Bureau yeMigodi yase-US kunye nelayisensi yi-UOP (ngoku inxalenye ye-Honeywell), yinkqubo ye-thermal regenerated, i-cyclical solvent process esebenzisa isisombululo se-K2CO3 esishushu sokususa i-CO2 kunye ne-H2S kwi-gas streams. Yindlela ethembekileyo yeukucocwa kwegesikumashishini afuna iigesi ezicocekileyo, ezifana ne-ammonia synthesis yezichumisi, imveliso ye-hydrogen yokusulungekiswa, kunye nokusetyenzwa kwegesi yendalo kwiinkcukacha zemibhobho. Inkqubo isebenza ngezigaba ezibini eziphambili: ukufunxa kunye nokuhlaziywa.
Ngethuba lesigaba sokuxutywa, i-gas stream ifakwe ngaphantsi kwekholomu ye-absorber, i-current counter-current kwisisombululo esishushu se-K2CO3 (ngokuqhelekileyo i-20-30 wt%) kumaqondo okushisa phakathi kwe-100 ° C kunye ne-110 ° C kunye noxinzelelo oluphezulu.
I-H2S nayo iyafunxwa, yenze ezinye iimveliso zokusabela. Igesi ecocekileyo iphuma phezulu kwi-absorber, ngelixa isisombululo esicebileyo, esithwele i-KHCO3, sidluliselwa kwi-regenerator (i-stripper). Kwinqanaba lokuvuselela, isisombululo sifudumala nge-steam okanye siphantsi kokunciphisa uxinzelelo, ukuguqula impendulo yokukhulula i-CO2 kunye ne-H2S, ngaloo ndlela ihlaziywa isisombululo se-K2CO3 sokusetyenziswa kwakhona. Le nkqubo ye-cyclical iqinisekisa ukusebenza okuqhubekayo, kodwa ukusebenza kwayo kuxhomekeke ekugcineni i-K2CO3 kunye ne-KHCO3 yogxininiso ukuphepha imiba yokusebenza.
Kutheni uLawulo lokuNxibelela lubalulekile
Ulawulo oluchanekileyo logxininiso lwesisombululo se-K2CO3 lubalulekile ngenxa yezizathu ezininzi. Amanqanaba aphezulu e-KHCO3 angakhokelela ekubeni igwebu kwi-absorber, ephazamisa ukudibana kwe-gas-liquid, ukunciphisa ukusebenza kakuhle kwe-CO2, kunye nomngcipheko wokulimala kwezixhobo. Ngokwahlukileyo, ukungonelanga kogxininiso lwe-K2CO3 kunciphisa umthamo wesisombululo sokufunxa iigesi ze-asidi, okukhokelela ekusulungekeni okungaphelelanga kunye nokungahambelani neenkcukacha zemveliso. Ukongezelela, ukugxininiswa okungafanelekanga kunokunyusa ukusetyenziswa kwamandla ngexesha lokuhlaziywa kwakhona, njengoko izisombululo ezityebileyo ezigqithisileyo zifuna i-steam engaphezulu yokukhupha iigesi ezibanjiweyo, kwaye zinokunyusa ukubola kwizixhobo ngenxa yendalo ye-alkaline yesisombululo.
Ngokwembali, ukubeka iliso kugxininiso kwakuxhomekeke kwisampulu yesandla kunye nohlalutyo lwebhubhoratri, inkqubo enzima kakhulu, ethanda ukulibaziseka, kwaye ayikwazi ukunika ukuqonda kwexesha lokwenyani. Le mida ingakhokelela ekungaphumeleli kwenkqubo, ukunyuka kweendleko zokusebenza, kunye nokuphulwa kokulawula okunokwenzeka.Iimitha zoxinaniso lwe-potassium carbonate ngaphakathiukujongana nale mingeni ngokubonelela ngemilinganiselo eqhubekayo, echanekileyo, ukwenza ulungelelwaniso olukhawulezileyo ukugcina iimeko zenkqubo ezigqwesileyo kunye nokuphucula ukusebenzaInkqubo yaseBenfieldScrubber.
Iimveliso ezicetyiswayo
Indlela ezisebenza ngayo iimitha zoxinaniso olusemLayini
Iimitha zoxinaniso lwe-potassium carbonate ngaphakathiokanyeabahlalutyiZibekwe phambili ekulayini inkqubo esweni eyilelwe ukulinganisa i-K2CO3kunye neKHCO3Ugxininiso ngqo ngaphakathi kumjelo wenkqubo, ukuphelisa imfuno yesampulu yesandla. Ezi zixhobo zenzelwe ukusebenza phantsi kweemeko ezinzima zeInkqubo yaseBenfield, kubandakanywa nokushisa okuphezulu (ukuya kwi-110 ° C) kunye noxinzelelo, kwaye zakhiwe ngezinto ezichasene ne-corrosion ukuze zimelane nemekobume ye-alkali yesisombululo se-scrubbing.
Kusetyenziswa iitekhnoloji ezininzi kwezi mitha, nganye ibonelela ngeenzuzo ezizodwa:
Umlinganiselo we-Ultrasonic: Ezi mitha zilinganisa isantya sesandi ngolwelo, oluhambelana noxinaniso kunye noxinaniso.
