Uhlelo lokwelapha igesi oluphakelayo
Indlela yenqubo ekhethiwe yokugeleza kwenqubo uhlelo lokwelapha igesi lokuphakelayo lunezici ezilandelayo:
(1) Uma kuqhathaniswa nendlela ye-MEA, indlela ye-MDEA inezici zokungabi namagwebu amaningi, ukugqwala okuncane kanye nokulahlekelwa ama-amine amancane.
(2) Iyunithi isebenzisa i-MDEA wet decarburization, futhi akukho ukusetshenziswa kwegesi yokuvuselela.
(3) Iphampu ejikelezayo ye-MDEA isebenzisa iphampu ye-centrifugal yesigaba esisodwa esheshayo, enokwethenjelwa okuphezulu, ukusetshenziswa kwamandla okuphansi kanye nokugcinwa okuncane.
(4) Ukumuncwa kwesihlungo sama-molecule kungasetshenziswa ekuphelelweni amanzi emzimbeni okujulile, futhi kusenezici eziphezulu zokumuncwa ngisho nangaphansi kwengcindezi encane yomhwamuko wamanzi.
(5) Ukusebenzisa ikhabhoni esebenzayo ukususa ama-hydrocarbon asindayo kungasusa ama-hydrocarbon anuka kamnandi kanye nama-hydrocarbon asindayo e-C6 +, kuxazulule ngokuphelele inkinga yokubanda nokuvimba okushisa okuphansi, futhi kuqinisekise ukusebenza kwesikhathi eside.
(6) I-Mercury isabela ne-sulfur ku-activated carbon efakwe i-sulfur ukuze ikhiqize i-mercury sulfide, efakwe ku-activated carbon ukuze kufezwe injongo yokususwa kwe-mercury. Ukusebenzisa i-activated carbon efakwe i-sulfur ukuze kususwe i-mercury kunentengo ephansi.
(7) Isici sesihlungi esinembile singahlunga isihlungi sama-molecule kanye nothuli lwe-carbon olusebenzayo lube yi-5 μm ngaphansi.
Uhlelo lokufaka uketshezi kanye nolwesiqandisi
Indlela yenqubo ekhethiwe ye uhlelo lokuphuza uketshezi kanye nokugcina ifriji yi-MRC (mixed refrigerant) cycle refrigerant, ebonakala ngokuthi:
(1) Ukusetshenziswa kwamandla okuphansi. Le ndlela inokusetshenziswa kwamandla okuphansi kakhulu phakathi kwezindlela ezivame ukusetshenziswa zokuqandisa, okwenza intengo yomkhiqizo incintisane emakethe.
(2) Uhlelo lokulinganisa i-refrigerant aluzimele kakhulu ohlelweni lokucindezela olujikelezayo. Ngesikhathi sokusebenza, uhlelo lokulinganisa lugcwalisa i-refrigerant ohlelweni lokucindezela olujikelezayo ukuze kugcinwe isimo sokusebenza esizinzile sohlelo lokucindezela olujikelezayo; Ngemva kokuba iyunithi ivaliwe, uhlelo lokulinganisa lungagcina i-refrigerant engxenyeni yokucindezela okuphezulu yesistimu yokucindezela ngaphandle kokukhipha i-refrigerant. Inhloso yokwenza lokhu: okokuqala, konga i-refrigerant, futhi okwesibili, kufinyezwe isikhathi sokuqala okulandelayo. Isikhathi sokuqala kweyunithi yokuphuza amanzi singaphansi kwamahora ama-5.
(3) Umthamo kanye nomfutho wohlelo lwesiqandisi kufanele kuklanywe ngendlela efanele. Ngemva kokuba iyunithi ivaliwe, uma kucatshangelwa ukuthi zonke iziqandisi ziphinde zifudunyezwe zifinyelele ekushiseni okuvamile futhi umfutho ulinganisiwe, uhlelo lusengaqukatha zonke iziqandisi, luqinisekise ukuthi zonke izingxenye zohlelo azicindezelwa kakhulu futhi azingenisi umoya, futhi luvumele isiqandisi ukuthi sihlale ohlelweni isikhathi eside.
(4) Wonke ama-valve eyunithi yoketshezi oluphansi lokushisa abekwe ngaphandle kwebhokisi elibandayo futhi ashiselwe ukuze kuncishiswe amaphuzu okuvuza futhi kube lula ukugcinwa kwama-valve. Akukho ukuxhumana kwe-flange ebhokisini elibandayo ukuze kuncishiswe amaphuzu okuvuza okungenzeka ebhokisini elibandayo. I-thermometer yamaphuzu amaningi kanye ne-gas probe kuhlelwe ukuqapha ukuvuza okungenzeka ebhokisini elibandayo ngesikhathi sangempela.
(5) Ubuchwepheshe obuthuthukisiwe busetshenziswa kabanzi ekwakhiweni kwebhokisi elibandayo. Kuzokwenziwa ukuhlaziywa kohlaka oluphelele, ipayipi kanye nokucindezeleka kwendawo ukuqinisekisa ukuthembeka kwebhokisi elibandayo kusukela ekhwalithini yokuklama. Okokuqala, iSoftware yobuchwepheshe ye-3D Design Solidworks isetshenziselwa ukusungula imodeli ye-3D yohlaka lwebhokisi elibandayo kanye nemishini yepayipi; Bese, i-cosmos isetshenziselwa ukuhlaziya ukucindezeleka kohlaka; Ukuze kuhlangatshezwane nomklamo oguquguqukayo wepayipi elisezingeni eliphansi lokushisa, isofthiwe yobuchwepheshe yokuhlaziya ukucindezeleka kwepayipi i-CAESAR II isetshenziselwa ukuhlaziywa kokucindezeleka kwepayipi; Uma uhlangabezana nenkinga yokuvula epayipini noma ngisho nokuvulwa okukhulu, ukuqinisekisa ukuthi ukucindezeleka ekuvulekeni kungaphakathi kwebanga elivunyelwe elichazwe kumazinga kazwelonke, isofthiwe ye-ANSYS izosetshenziselwa ukuhlaziywa kokucindezeleka kwendawo.
