Uphuhliso kwiTekhnoloji yeSise yeMolekyuli luphucula ukusebenza kakuhle kokucoca igesi kunye nokusebenza kakuhle kokucoca igesi
Ishishini lokucubungula igesi yendalo libona inkqubela phambili ebalulekileyo kwi-molecular sieve desulphurization kunye netekhnoloji yokuphelisa ukungcola, eqhutywa kukwanda kweemfuno zeenkcukacha zamafutha ezicocekileyo kakhulu kunye nokusebenza kakuhle. Izinto ezintsha zakutshanje zigxile ekuphuculeni uzinzo lwe-catalyst kunye nokukwazi ukuhlaziya izixhobo zokuphelisa ukungcola kwegesi yendalo, ngakumbi kwizityalo ze-LNG kunye nokubuyiselwa kwe-NGL kwizicelo zegesi yendalo.
Eyona nto iphambili kukuphuhliswa kwee-sieves ze-molecular ze-mesoporous ezifakwe i-cobalt-doped ezifakwe i-N,N-dihydroxypyromellitimide (Co-SBA-15-NDHPI), ezibonisa uzinzo olurekhodiweyo ngexesha le-catalytic oxidative desulfurization. Le composite ye-organic-inorganic iqinisa isiphumo se-synergistic phakathi kwezinto ezisebenzayo kunye neenkxaso ezinemingxuma, iphucula kakhulu ukusebenza kokuguqulwa kwe-sulfide-to-sulfone ngelixa ixhathisa ukungasebenzi.
Idibeneyo Iiyunithi zokuphelisa amanzi emzimbeni Ukufumana Amandla
Uyilo lwanamhlanje lweeyunithi zokukhupha amanzi emzimbeni lubandakanya olu phuculo kunye nezikhokelo zokusebenza eziphuculweyo:
Uqwalaselo lweModular: Iiyunithi ezifakwe kwi-skid ezinokutshintsha okuzenzakalelayo phakathi kokufunxa, ukuhlaziya, kunye nemijikelo yokupholisa (iinkqubo ezimbini okanye ezintathu) zivumela ukusebenza kwe--70°C okuqhubekayo kwamanzi dewpoint kubalulekile kakhulu I-LNG/iinkqubo ze-NGL
Ukusebenza kakuhle kokuhlaziya: Izifudumezi ezisebenzisa umbane okanye ezisebenzisa umbane ngoku zihlaziya izihluzo zemolekyuli kwi-230-300°C zisebenzisa igesi eyomileyo, zibuyisela amandla okufunxa ngelixa zinciphisa ukusetyenziswa kwamandla ukuya kuthi ga kwi-30%
Ulawulo lwezinto ezininzi ezingcolisa ukungcola: Ii-seeves ze-molecular ze-Next-gen zijolise ngaxeshanye kwi-H₂S, i-SO₂, kunye nomphunga wamanzi ngokusebenzisa izakhiwo ze-pore ezilungiselelwe wena—i-microporous (
Ukuphunyezwa kwentsimi kunye nokusebenza
Kwi-terminal yaseShandong LNG eTshayina, iiyunithi zokuphelelwa ngamanzi emzimbeni eziphuculweyo zinciphise ukuphindaphinda rhoqo ngama-40% ngelixa zigcina iinkcukacha zegesi yemveliso zingaphantsi kwe-0.1 ppm sulfur compounds kunye ne--70°C dew point. Ngokufanayo, iPermian Basin Ukubuyiselwa kwe-NGL Izakhiwo zibika ubomi besihluzo obude obuyi-15% emva kokutshintshela kwi-vanadium-modified ZSM-5 molecular sieves, ezonyusa ukusebenza kakuhle kwe-thiophene desulfurization nge-11% xa kuthelekiswa nezixhobo eziqhelekileyo.
"Ukuhlanganiswa kwezinto ezizinzisa kakhulu zokukhupha i-sulfurization kwiinqaba zokukhupha amanzi emzimbeni kubonisa utshintsho oluqhelekileyo. Izityalo azisayidingi iiyunithi ezahlukeneyo zokususa i-sulfur namanzi, zinciphisa i-CAPEX ngama-25% ngelixa zifikelela kwigesi yepayipi kwinqanaba elinye." — Jiangsu Rudy Inkokeli yoBunjineli bePetrochemical
Njengoko urhwebo lwehlabathi lwe-LNG luqikelelwa ukuba luza kukhula nge-70% ngo-2040, uphuhliso lwe-molecular seeve lukulungele ukuxhasa iinjongo ezimbini zoshishino zokukhula kunye nokunciphisa ukukhutshwa komoya. Uphando oluqhubekayo lujolise kwii-sieve ezisekelwe kwi-MOF ezinezakhono zokwahlulahlula iimolekyuli ukuze ngaxeshanye zisuse iintlobo ze-mercury, amanzi, kunye ne-sulfur kwizixhobo zokuphelisa amanzi kwigesi yendalo yesizukulwana esilandelayo.
