Ukusafisha Kwegesi Lenyoka

Izixhobo zokucula kwamagasi angcwele yindlela ebalulekileyo yokulungisa phambi kokusetshenziswa (ukuthunyelwa kwegolide, ukugcinwa, uhlelo lwemfundo, nokulungisa). Isondelula izinkohlaka ezihlakhekayo, ihlanzelela imithetho yesimo (GB 17820, GB 18047, GB/T 38753, njalo), isebenza izixhobo ezindaweni ezifolofolonke, kanye nokuwaba iziphumo ezinezimali ephakeme.

Izixhobo zethu zokuhlaka zifanelekile kwiintsontso ezahlukeneyo, njenge: intsholongwenya yasekhishini lasezintsholongweni, intsholongwenya yasepipe, intsholongwenya yesilafu, intsholongwenya yekholejika, intsholongwenya yesilumo, intsholongwenya yokuphendula, kunye ne-intsholongwenya epheleleyo yezinto eziphakamileyo. Ixhobo isebenza ngaphantsi kwezinga eliphambili lokugquba, nesilinganiso sekuhla okusebenza kusikhala phakathi kuka-30% ukuya ku-110%. Sinazo zonke izexperience ekulungiseni intsholongwenya enobunzima obukhulu be-organic sulfur, i-H₂S, kunye ne-CO₂. Umdlalo othintelwe kakhulu unceda ekunciphiseni indawo, ukudlela ixesha lokukhula, kunye nokunciphisa imali yokufaka. Ngaphezu koko, uyatholakala neendawo zokulinganisa ukuze ziphinde ziphumelele iingcinga zokusebenza ngexesha elithile kwaye zenzeke ubumfihlo, kunye nendawo yokhuseleko esebenzayo ukuqinisekisa ukusebenza okqinile.

Isicatshulwa—Xinjiang Luntai 220,000 Nm³/h Isixhobo sokukhupha kanye nokugaya

·Inkcazo yeMDEA ebeka umbiko wokukhupha:

Igasi lokulayisha lilahlekelwa ngapha kwehlelo lokuhlambalazekayo futhi lihlangene ngezansi yesilinda sokumelana, lapho sithinta isolution ephansi ye-MDEA eshiywe kulesohlangothini kuqondana nokudla okuphakade. CO₂ ne-H₂S zimelanelwa khona. Isolution engenamandla ihlukunyezwa ngokudala kwe-flash tank ukususa i-hydrocarbons, ikhanyiselwa kulean-rich solution heat exchanger, bese lihlangene ngezansi yesilinda sokubuyisa. Ngaphansi kwegasi likagereka kwi-reboiler, CO₂ ne-H₂S zibuyiselwa. Isolution esiphinde siphinde sabekwe silahlukaniswa, silahlazelwa, futhi silahliselwa kabusha emuva kusilinda sokumelana ukuzulazula. Igasi elihlangothini lesilinda lingathunyelwa amathuba okubuyisa isulfur noma izigaba ze-CO₂ liquefaction.

·Inkcazo yendlela yokususa umlilo we-Molecular Sieve:

Emva kokukhupha ukhaboni, igesi yamandla ingena eToweni A yokumeka, lapho amanzi akhokhelwa ngokukhetha yi molecular sieve bed. Igesi esuswe emuva ekhulula ukugcina kwezimali ≤ -60°C bese isendelwa phansi. Emva kokugcina kwamandla, Towere B ihlanjiswa ngenqubo yokubuyisa: igesi esuswe emuva noma inyuthini iyashiselwa kwiheiti bese isetshenziswa ukucwasa ngokudluliselwa ku-molecular sieve bed. Amakhulu okugcina akhokhelwa kusihlwanjini kanye asungulwe kusihambe. Ngemuva kwalokho, igesi esuswe emuva esibindi setshenziswa ukusabela phambi kwesihlwanjini ku-40°C, ukuqeda ukubuyisana kusimemeza. Izitoweri ezimbili zihlanjiswa ngokuzenzakalelayo ngamatshini aphrogramekile, ngehora yokuqala ye-8–12.

·Umbiko wokwenza okwesibindi + Umbiko wokwenza Okusekelwe ku-Temperature Swing (TSA):

Emva kokususa umlilo ngomkhumbi we-molecular sieve, igesi yamva ikhona kwi-plate-fin heat exchanger ukulahlaza kabusha, okwakhiwa kumcondensela okuncane kwe-C₅+ imitholwane engenahlobo. Kantiya kulahlaziywa ngokugqagqayo ngendlela ye-turbo-expander noma ingcindezi egcinezileyo, kwaye igazi (lenzeke LPG/NGL) isungulwa kwi-low-temperature separator. Imitholwane engenahlobo ephakathi kwigasi ikhona kwi-TSA molecular sieve adsorption tower, apho imitholwane engenahlobo isungulwa ngokukhethileyo. Igasi eliselayo, enenani lezinto ezingenahlobo ≤ 20 mg/Nm³, lithunyelwa kwi-yuniti ye-liquefaction. Emva kokugcwalisa ngokusungulwa, igasi eligcweleyo elilahlaziywa lukhuselelwa ukwenza ukusabela kwakhona. Imitholwane engenahlobo ethathwa iyuqhafuza kwaye ihlanjululwe, kwaye igasi lokujikeleza liyisetyenziso njengegasi lokusiza.

·Ukudweba Okugcweleyo Ngokwahlulwa Kwiganja:

Emva kokusilwa kwehydrocarbon, igesi ethile ikhulula ukwenta umlando ngenitrojini yasendlelini kanye nemethane yaphansi kwisahluko sokulima okuqala ukuze kulahlwe ubomi bokukhanya kwaye kubeke ngokuncinci ihydrocarbons ezikhulu. Emva koko ihluka kumthwalo wamandla, apho ikhazimula kakhulu kuya ku-162°C ngomthwalo ophathelene we-DMR futhi ingene ekedini lenitrojini. Initrojini yasendlelini isabalaliswa ngokugcwele kumkhiqizo, ngelixa imethane yaphansi isabelaliswa kumthwalo wamandla futhi iphinde ilinde, ihlanza uhlelo lwesithuthi. Imethane yaphansi iyaphinde ikhanyiswe kubomi bokuphela kwaye inikezwa njengegesi yezimpahla. Initrojini engcwele yasendlelini isetshenziswa njengegesi yesidumo emva kokurholophwa kwegesi esigxenyeni, ihlanganisa ukurhweleka kwegesi.

·Ukwenza, Ufundiswa, nokumisa Kuphela:

Iyagcinwa ngemodi kuzoshishintshwa kumgangatho kanye nokufakwa kusayithi, ukuqinisekisa ukuletha kahle kwezimpahla. Umkhawulo wokuphelele kusayithi kusuku lokugcina kuya kusuku lokuhlehliswa kuyisikhanga esihlanu.

Sikubonisa akukho amathuluzi okuthuthukisa teknoloji, okuthuthukisa ubuhle obuhle, nokuthuthukisa ukuthengiswa kwezinto, kodwa futhi izisombululo nezinkonzo zokugcina umsebenzi.

Umbuzo: Amahlayibheli akho abhekise emaphrojekthini amabili?
Yebo, amahlayibheli akho aneminyaka eyisi-15 yamandulo lokusebenza lolu lwazi, futhi babhekise emandulo yokudesign, ukwenza, ukufaka, nokuvula kwamathuluzi eTurkhi, eJiphti, naseMyanmar.

Umbuzo: Ngingakuthola njani inani elihlukile lokuthengiswa kwesiqephu?
Sicela usitsho izidingo zakho zokuphepha nezinhlobo zedatha zokuhlala, ukuze sibonise iziqephu nezisombululo esizofanele kakhulu kuleli simo.
