Sulfur Recovery ke Eng?
Pholiso ea sebaboleke ts'ebetso ea bohlokoa indastering ea tlhoekiso ea peterole, e reretsoeng ho tlosa metsoako ea sebabole oling e tala le tse tsoang ho eona. Ts'ebetso ena e bohlokoa bakeng sa ho kopana le melao ea tikoloho le ho hlahisa libeso tse hloekileng. Lik'hemik'hale tsa sebabole, haeba li sa tlosoe, li ka lebisa ho thehoeng ha sulfur dioxide (SO₂) nakong ea mollo, e tlatsetsang tšilafalong ea moea le pula ea acid. Ts'ebetso ea ho hlaphoheloa sebabole hangata e kenyelletsa ho fetola hydrogen sulfide (H₂S), sehlahisoa sa ho hloekisa, ho ba sebabole sa mantlha kapa sulfuric acid.
E 'ngoe ea mekhoa e sebelisoang haholo ea hoho hlaphoheloa sebaboleke mokhoa oa Claus, o kenyelletsang letoto la liphetoho tsa lik'hemik'hale tse fetolelang H₂S hore e be sebabole sa motheo. Ts'ebetso hangata e kenyelletsa methati ea mocheso le ea matla, moo H₂S e qalang ka mokhoa o itseng oxidized ho sulfur dioxide (SO₂) ebe e arabela ka H₂S e eketsehileng ho hlahisa sebabole le metsi. Ts'ebetso ea ts'ebetso ea Claus e ka ntlafatsoa ka ho e kopanya le mekhoa e meng ea theknoloji, e kang likarolo tsa phekolo ea khase ea mohatla, ho finyella litekanyetso tse phahameng tsa ho khutlisa sebabole.
PR-100 le Karolo ea eona ho Pholiso ea Sebabole
PR-100 ke sesebelisoa sa thepa se sebelisoang ts'ebetsong ea ho khutlisa sebabole. E etselitsoe ho ntlafatsa katleho ea ts'ebetso ea Claus ka ho ntlafatsa litekanyetso tsa phetoho ea H₂S ho elemental sulfur. ThePR-100 e thusange tsejoa ka mosebetsi oa eona o phahameng le botsitso, e leng se lumellang hore ho be le ts'ebetso e ntle ho lihlopha tsa ho hlaphoheloa ha sebabole. Ka ho sebelisa PR-100, li-refineries li ka fumana litekanyetso tse phahameng tsa ho khutlisa sebabole, tsa fokotsa mesi, le ho latela melao e thata ea tikoloho.
The PR-100 catalyst e sebetsa ka ho fana ka sebaka se nepahetseng bakeng sa lik'hemik'hale tse amehang ts'ebetsong ea Claus. E thusa ho oxidation ea H₂S ho SO₂ le karabelo e latelang ea SO₂ le H₂S ho etsa sebabole. Sebaka se phahameng sa catalyst le libaka tse sebetsang li netefatsa hore liketso tsena li etsahala hantle, esita le mocheso o tlase. Sena ha se ntlafatse feela tekanyo ea kakaretso ea ho khutlisa sebabole empa hape se fokotsa tšebeliso ea matla ea ts'ebetso.
Phetoho ea CCR bakeng sa Tlhahiso ea Peterole
Continuous Catalytic Reforming (CCR) ke ts'ebetso ea bohlokoa tlhahisong ea peterole e phahameng ea octane. E kenyelletsa phetoho ea "low-octane naphtha" hore e be high-octane reformate, e leng karolo ea bohlokoa ea peterole. Ts'ebetso ea CCR e sebelisa sesebelisoa se thehiloeng ho platinum ho thusa dehydrogenation, isomerization, le cyclization ea hydrocarbons, e leng se etsang hore ho thehoe metsoako e nkhang hamonate e matlafatsang tekanyo ea octane ea peterole.
Ts'ebetso ea CCR e ntse e tsoela pele, e bolelang hore catalyst e tsosolosoa sebakeng, e leng se lumellang ts'ebetso e sa sitisoeng. Sena se finyelloa ka ho tsoela pele ho tlosa mokelikeli o sebelisitsoeng, ho o tsosolosa ka ho chesa li-deposit tsa coke, ebe o o khutlisetsa ho reactor. Boemo bo tsoelang pele ba ts'ebetso ea CCR bo netefatsa phepelo e tsitsitseng ea reformate ea high-octane, e leng bohlokoa bakeng sa ho finyella tlhokahalo ea peterole ea boleng bo phahameng.
Ho kopanngoa ha Sulfur Recovery lePhetoho ea CCR
Ho kopanngoa ha mekhoa ea ho tsosolosa sebabole le mekhoa ea ho fetola CCR ho bohlokoa bakeng sa lisebelisoa tsa morao-rao. Ts'ebetso ea ho khutlisa sebabole e netefatsa hore H₂S e hlahisoang nakong ea ho hloekisoa e fetoloa ka nepo ho ba sebabole sa mantlha, e fokotsang mesi le tšusumetso ea tikoloho. Ka lehlakoreng le leng, ts'ebetso ea ntlafatso ea CCR e ntlafatsa boleng ba peterole ka ho eketsa tekanyo ea eona ea octane.
Ka ho kopanya lits'ebetso tsena, li-refineries li ka fihlela tumellano ea tikoloho le boleng ba sehlahisoa. Tšebeliso ea li-catalyst tse tsoetseng pele joalo kaPR-100ho tsosolosoa ha sebabole le li-catalyst tse thehiloeng ho platinum ho ntlafatso ea CCR ho netefatsa hore mekhoa ena e sebetsa hantle ebile e sebetsa hantle. Kopanyo ena ha e thuse feela libaka tsa ho hloekisa ho fihlela litlhoko tsa taolo empa hape li li nolofalletsa ho hlahisa libeso tsa boleng bo holimo tse khotsofatsang litlhoko tsa 'maraka.
Qetellong, ho khutlisa sebabole ke ts'ebetso ea bohlokoa indastering ea tlhoekiso ea peterole, e reretsoeng ho tlosa metsoako ea sebabole le ho fokotsa mesi. Tšebeliso ea li-catalyst tse tsoetseng pele joalo kaPR-100e ntlafatsa ts'ebetso ea ts'ebetso ea ho khutlisa sebabole. Ho feta moo,Ho fetola CCRe bapala karolo ea bohlokoa ho hlahiseng peterole e nang le octane e ngata. Ho kopanngoa ha mekhoa ena ho etsa bonnete ba hore libaka tsa ho hloekisa li ka finyella bobeli ba ho lumellana le tikoloho le boleng ba lihlahisoa, ho kenya letsoho sebakeng se hloekileng le se sebetsang hantle sa matla.
