Kuyini ukululama sulfur?
Ukuvuselelwa kwesibabuleIngabe inqubo ebucayi embonini yokucwengelwa kwamaphethiloli, okuhloswe ngayo ukususa amakhompiyutha sulfur kusuka kumafutha aluhlaza kanye nokutholakala kwayo. Le nqubo ibalulekile ekufezeni imithetho yezemvelo futhi ikhiqize amafutha okuhlanza. Amakhompiyutha e-Sulfur, uma engasuswanga, angaholela ekwakhekeni kweSulphur Dioxide (So₂) ngesikhathi sokuvutha, ukufaka isandla ekungcoleni komoya kanye nemvula ye-acid. Inqubo yokubuyiselwa kwesibanfur imvamisa ifaka ukuguqula i-hydrogen sulfide (H₂s), ukugcwaliswa kokucwengile, ku-sulfur emangalisayo noma i-sulfuric acid.
Enye yezindlela ezisetshenziswa kakhulu zeUkuvuselelwa kwesibabuleInqubo ye-CLAUS, efaka uchungechunge lokuphendula kwamakhemikhali aguqula i-H₂s ibe yisibabule sangaphambilini. Le nqubo ivame ukufaka izigaba ezishisayo neze-catalytic, lapho i-H₂s iqala ngokwengxenye ye-sulphur dioxide (so₂) bese iphendulwa ngama-HLS amaningi ukukhiqiza isibabule namanzi. Ukusebenza kahle kwenqubo ye-CLAUS kungathuthukiswa ngokuyihlanganisa nobunye ubuchwepheshe, njengamayunithi wokulashwa igesi yomsila, ukufezekisa amanani aphezulu wokubuyiselwa kwe-sulfur.
I-PR-100 neqhaza layo ekubuyiselweni kweSulfur
I-PR-100 iyi-catalyst ye-proprietary esetshenziswe kwinqubo yokubuyiselwa kwe-sulfur. Kwenzelwe ukuthuthukisa ukusebenza kahle kwenqubo ye-Claus ngokwenza ngcono amanani okuguqulwa kwe-H₂s kwisibabule sama-Element Sulfur. Le khasiPr-100 CatalystYaziwa ngomsebenzi wayo ophakeme nokuqina, okuvumela ukusebenza okungcono kumayunithi wokutakula we-sulfur. Ngokusebenzisa ama-PR-100, ama-Revineries angathola amanani aphezulu wokubuyiselwa kwama-sulfur, anciphise ukuphuma, futhi ahambisane nemithetho yemvelo eqinile.
I-CR-100 Catalyst isebenza ngokunikeza indawo efanelekile yokusabela kwamakhemikhali ebandakanyeka kwinqubo ye-Claus. Kusiza i-oxidation of H₂s to ₂₂ Ukusabela okulandelayo kwe-So₂ nge-H₂s ukwakha isibabule. Indawo ephezulu ye-catalyst ephezulu kanye neziza ezisebenzayo ziqinisekisa ukuthi lokhu kusabela kwenzeka kahle, ngisho nasemazingeni okushisa aphansi. Lokhu akugcini nje ngokuthuthukisa isilinganiso sokuthola kabusha se-sulfur kodwa futhi kunciphisa ukusetshenziswa kwamandla kwenqubo.
I-CCR Reform ukukhiqizwa kukaphethiloli
I-CCRYTIC REFFRICTIC AREFFRIMING (CCR) iyinqubo ebalulekile ekwakhiweni kukaphethiloli ophakeme. Kubandakanya ukuguqulwa kwe-Low-Octane Naphtha ku-High-Octane Refformate, okuyingxenye esemqoka kaphethiloli. Inqubo ye-CCR isebenzisa i-catalyst esekelwe kwiplatinamu ukwenza lula i-dehydrogenation, isomerizatizo
Inqubo ye-CCR iyaqhubeka, okusho ukuthi i-catalyst iphinde yafakwa kabusha e-SITU, ivumela ukusebenza okungaphazanyiswa. Lokhu kutholakala ngokususa ngokuqhubekayo i-catalyst esetshenzisiwe, ukuyivuselela ngokushisa ngokushisa amadiphozithi we-coke, bese uyiphinda kabusha ibe yi-reactor. Uhlobo oluqhubekayo lwenqubo ye-CCR luqinisekisa ukulethwa okuqhubekayo kwe-High-Octane Refformate, okubalulekile ekuhlangabezaneni nesidingo sikaphethiloli osezingeni eliphakeme.
Ukuhlanganiswa kokubuyiselwa kweSulfur futhiI-CCR iguquko
Ukuhlanganiswa kwezinqubo zokuvuselelwa kweSulfur kanye ne-CCR Reformeting izinqubo kubalulekile ekuhlaziyweni kwesimanje. Inqubo yokubuyiselwa kweSulfur iqinisekisa ukuthi ama-H₂s akhiqizwa ngesikhathi sokucwengisisa aguqulwa ngempumelelo ibe isibabule sangaphambilini, anciphise ukuphuma kwemiphumela kanye nomthelela wezemvelo. Ngakolunye uhlangothi, inqubo yokuguqula kabusha i-CCR ithuthukisa ikhwalithi kaphethiloli ngokwandisa isilinganiso sayo se-octane.
Ngokuhlanganisa lezi zinqubo, ama-conferies angafinyelela zombili ukuthobela kwezemvelo nekhwalithi yomkhiqizo. Ukusetshenziswa kwama-catalysts athuthukile afanaI-PR-100Ekubuyiselweni kwe-sulfur kanye ne-platin-based Catalysts ku-CCR Reform Ukuqinisekisa ukuthi lezi zinqubo zisebenza kahle futhi zisebenza. Lokhu okuhlanganisiwe akugcini nje kuphela ukusiza izimilo ezihlangabezana nezidingo zokulawula kepha futhi kubenza bakwazi ukukhiqiza amafutha asezingeni eliphakeme ahlangabezana nezidingo zemakethe.
Ekuphetheni, ukululama kweSulfur kuyinqubo ebalulekile embonini yokucwengeka kaphethiloli, okuhloswe ngayo ukususa amakhompiyutha sulfur kanye nokunciphisa ukuphuma. Ukusetshenziswa kwama-catalysts athuthukile afanaI-PR-100Ithuthukisa ukusebenza kahle kwenqubo yokubuyiselwa kwe-sulfur. Ngokwengeziwe,I-CCR iguqukoIdlala indima ebalulekile ekukhiqizeni uphethiloli ophakeme. Ukuhlanganiswa kwalezi zinqubo kuqinisekisa ukuthi ama-confereries angafinyelela zombili ukuthobela kwezemvelo kanye nekhwalithi yomkhiqizo, okufaka isandla ekuhlanzeni amandla kanye nokusebenza kahle kwezwe.
