Incazelo Yemikhiqizo
Indawo yokucubungula igesi yemvelo (eyaziwa nangokuthi isikhungo sokuhlanza igesi yemvelo) iyisethi enkulu-yesikali esiphelele sezinto zokusebenza ezicubungula igesi yemvelo eluhlaza ngokusekelwe ekuhlukaniseni ngokomzimba nezindlela zokuhlanza amakhemikhali.
Umgomo wayo oyinhloko ukusebenzisa umehluko wezakhiwo ezifana nendawo yokubilisa, ukunyibilika, namandla okukhangisa phakathi kwe-methane nezinye izakhi (njengamanzi, i-carbon dioxide, i-hydrogen sulfide, nama-hydrocarbons asindayo) kugesi yemvelo eluhlaza ukuze kukhishwe ukungcola futhi kuhlukaniswe{0}}ngemikhiqizo ngezinqubo ezinjengokuphelelwa amanzi emzimbeni, i-desulfurization, nefraction.
Ingakhiqiza ngokuzinzile-igesi yemvelo yekhwalithi ephezulu futhi ingesinye sezisetshenziswa ezisetshenziswa kakhulu embonini yegesi yemvelo.
Isimiso sokusebenza
Inqubo yokusebenza Yesikhungo Sokuhlanza Igesi Yemvelo ingafingqwa njengezinyathelo eziyisithupha ezibalulekile: ukucindezelwa kwegesi eluhlaza → ukuphelelwa amanzi emzimbeni → ukukhishwa kwe-sulfurization/ukukhipha ikhabhoni → ukuhlukaniswa kwe-hydrocarbon → ukwenqaba i-nitrogen (ongakukhetha) → ukuphuma komkhiqizo
Ukucindezelwa kwegesi eluhlaza:Igesi yemvelo eluhlaza (imvamisa ku-0.5-5.0 MPa) icindezelwa ku-2.0-10.0 MPa nge-compressor, ihlinzeka ngezimo zokuhlukaniswa nokuhlanzwa okulandelayo.
Ukuphelelwa amanzi emzimbeni:Igesi eluhlaza ecindezelwe ingena ohlelweni lokuqeda amanzi emzimbeni (i-adsorption tower noma i-glycol dehydration unit) ukuze ikhiphe umhwamuko wamanzi (ukugwema ukwakheka kwama-hydrate kanye nokugqwala kwamapayipi), ukwehlisa okuqukethwe kwamanzi kube ngaphansi kuka-100 mg/Nm³.
I-Desulfurization/decarbonization:Igesi ephelelwe amanzi emzimbeni ingena ohlelweni lokuhlanza ukuze ikhiphe i-sulphur-equkethe izinhlanganisela (njenge-hydrogen sulfide) kanye ne-carbon dioxide. Izindlela ezijwayelekile zifaka ukumuncwa kwe-amine (-zezitshalo ezinkulu) kanye ne-adsorption (yezitshalo-ezincane), ukwehlisa isamba sesibabule sibe ngaphansi kuka-20 mg/Nm³ kanye ne-carbon dioxide ibe ngaphansi kuka-3% (V).
Ukuhlukaniswa kwe-Hydrocarbon:Igesi ngemva kokususwa kokungcola ingena kuyunithi yokuhlukanisa (imvamisa isihlukanisi se-cryogenic noma umbhoshongo wokucwiliswa emanzini) ukuze kuhlukaniswe ama-hydrocarbon asindayo (i-ethane, i-propane, i-butane, njll.) ngokusebenzisa umehluko wamaphuzu abilayo. Lesi sinyathelo silungisa inani le-calorific legesi yomkhiqizo futhi sibuyisela i-liquefied petroleum gas (LPG) kanye nophethiloli wemvelo.
Ukwenqatshwa kwe-nitrogen (ongakukhetha):Uma igesi eluhlaza inokuqukethwe kwe-nitrogen ephezulu (Inkulu noma ilingana no-5%), iyunithi yokulahla i-nitrogen (kusetshenziswa ukuhlukaniswa kwe-cryogenic noma ukuhlukaniswa kwe-membrane) yengezwa ukunciphisa okuqukethwe kwe-nitrogen ibe ngaphansi kuka-2%, ukuqinisekisa inani lekhalori legesi yomkhiqizo.
Okukhipha umkhiqizo:Igesi yemvelo ecutshunguliwe (okuqukethwe kwe-methane Okukhulu noma okulingana nama-95%) kulinganiswa futhi kuhanjiswe emapayipini ukuze athuthwe; ehlukaniswe-yimikhiqizo (efana nesibabule, i-LPG, nophethiloli wemvelo) agcinwa noma aqhutshekwe acutshungulwe ukuze asetshenziswe ezimbonini.

Ukuqhubeka
Uma isiqalile futhi isebenza ngokuzinzile, ingasebenza ngokuqhubekayo isikhathi eside, ngomjikelezo ojwayelekile wokusebenza weminyaka engu-2-4 (odinga ukulungiswa okujwayelekile kokuvalwa kokushintshwa kwe-catalyst/adsorbent).
03
Kucebile-ngemikhiqizo
Ngaphezu kwegesi yemvelo ehlanziwe,{0}}ngemikhiqizo efana ne-elemental sulphur (kusuka ku-desulfurization), i-LPG, nophethiloli wemvelo ingabuyiselwa, kuthuthukiswe ukusebenza kahle kokusetshenziswa kwezinsiza.
04
Ukuhlanganiswa kwenqubo eyinkimbinkimbi
Isitshalo sihlanganisa amayunithi amaningi (ukucindezela, ukuphelelwa amanzi emzimbeni, ukuhlanzwa, ukuhlukaniswa), okudinga ukulawulwa okunembile kwemingcele efana nokucindezela, izinga lokushisa, nokugeleza ukuze kuqinisekiswe ukusebenza okuzinzile.

Izinzuzo zemikhiqizo yenkampani yethu
Kule nkathi yamanje lapho kugcizelelwa ukusebenza kahle kwamandla nokuvikelwa kwemvelo, idizayini ecolisisiwe iyitshe legumbi lokuqinisekisa ukusebenza kahle, okuphephile, nokuncane{0}}kwezindawo zokucubungula igesi yemvelo. Inkampani yethu inethimba lonjiniyela abangochwepheshe abaneminyaka engaphezu kwengama-30 yokuhlangenwe nakho kokucubungula igesi yemvelo, ejwayelene namazinga ahlukahlukene asekhaya nawangaphandle kanye nokucaciswa, okuhlanganisa i-GB, i-API, i-ASME, i-ISO, ne-EN. Sihlinzeka ngedizayini eyenziwe ngokwezifiso esekelwe ekwakhekeni kwegesi eluhlaza (isb, okuqukethwe kwesibabule, okuqukethwe kwe-hydrocarbon esindayo) kanye nezimfuneko zekhasimende (isb, ukucaciswa komkhiqizo,{8}}ngezidingo zokutholwa komkhiqizo), ukuthuthukisa imizila yezinqubo, ukukhethwa kwezinto zokusebenza, nokuhlanganiswa kwamandla (njengokuthola ukushisa kukadoti) ukuze kuncishiswe ukusetshenziswa kwamandla ngo-5-10% uma kuqhathaniswa nemiklamo evamile. Silahla izifanekiso ezijwayelekile futhi senza idizayini enemininingwane yephrojekthi ngayinye ukuze ivumelane nezici ezithile zegesi eluhlaza.
Inkampani yethu isebenzisa ngokuqinile uhlelo lokuphathwa kwekhwalithi ye-ISO9001 kanye nohlelo lokuphathwa kwemvelo lwe-ISO14001 kuwo wonke umjikelezo wephrojekthi, ohlanganisa ukwakheka, ukuthengwa kwempahla, ukwakhiwa, kanye nokugunyazwa. Phakathi nesigaba sokuklama, ukulingiswa kwenqubo kusetshenziselwa ukuqinisekisa ukusebenza kahle kokuhlukanisa kanye nokusetshenziswa kwamandla; izinto ezisetshenziswayo ezibalulekile (izimpindezi, imibhoshongo ye-adsorption, izishintshisi zokushisa) zihlolwa{3}}umuntu wesithathu ukuze kuqinisekiswe ukuthotshelwa kwezindinganiso; ukwakhiwa kulandela izinqubo zokushisela eziqinile (ezinesitifiketi se-WPS/PQR) kanye{4}}nokuhlola okungabhubhisi (UT, RT, PT) kwemikhumbi yomfutho; ukugunyazwa kuhlanganisa -ukuhlolwa kokusebenza okuqhubekayo kwamahora angu-72 ukuze kuqinisekiswe ukuhlanzeka komkhiqizo, umthamo wokucubungula, nezinkomba zokukhishwa kwezinto. Lokhu kuphatha okuhlelekile kuqinisekisa ikhwalithi yephrojekthi kanye nokulethwa ngesikhathi.
Sibheka ikhwalithi yomkhiqizo njengendlela yokuphila yebhizinisi futhi sizibophezele ekuletheni{0}}izitshalo zokucubungula ezinokwethenjelwa okuphezulu. Isitshalo ngasinye sithola ukulawulwa kwekhwalithi okuqinile: ama-adsorbent nama-catalysts akhethwa ezinkampanini ezidumile emhlabeni wonke ezinempilo yesevisi engu-2-iminyaka emi-5; imikhumbi yomfutho kanye namapayipi akhiqizwa ngokuhambisana namazinga e-ASME BPVC noma GB 150, anempilo yokuklama Enkulu kuneminyaka engu-20 noma elingana; isitshalo esiqediwe sizuza izinga lempumelelo yokuqala engu-100% kanye nezinga lokusebenza elizinzile lika-Greater noma elilingana nama-95% (ngaphandle kokulungisa). Sihlinzeka ngemibhalo ephelele yesitifiketi sekhwalithi, okuhlanganisa izitifiketi zezinto ezibonakalayo, imibiko yokuhlola, namamanuwali okusebenza.
Ukusebenza kahle ngemva{0}}kwesevisi yokuthengisa kubalulekile ukuze kuqinisekiswe ukusebenza okuqhubekayo kwefekthri. Lapho sithola isicelo sesevisi, ithimba lethu lochwepheshe linikeza impendulo yokuqala phakathi kwamahora angu-12 (24/7) ngefoni, i-imeyili, noma inkomfa yevidiyo, okuhlanganisa ukuhlonza inkinga nezisombululo zokuqala. Ezindabeni ezikude{6}ezixazululeka (isb, ukulungiswa kwepharamitha), siqondisa ukulungiswa phakathi namahora angu-24; ngezidingo{10}}zokunakekelwa kwesayithi, onjiniyela bathunyelwa emahoreni angu-48 (zasekhaya) noma amahora angu-72 (amazwe ngamazwe) ngemva kokuqinisekisa isidingo. Siphinde sinikeze ngezinsizakalo zokuvikela ezijwayelekile zokulungisa kanye nezingxenye ezisele ukuze kuncishiswe isikhathi sokuphumula.
Inkampani yethu ingahlinzeka ngemishini eyenziwe ngokwezifiso yesitshalo sokucubungula igesi yemvelo ngendlela yamaphrojekthi we-turnkey we-EPC (Engineering, Procurement, Construction), kanye nokuhlinzeka ngezinsizakalo zobuchwepheshe ezifana nokwenza kahle kwenqubo kanye neziqondiso zokusebenza. Kumakhasimende anezidingo-zesikhathi eside zokuphakelwa kukaphethiloli, siphinde sinikeze amamodeli okusebenza ngokubambisana (ukutshalwa kwezimali okuhlangene ezitshalweni kanye nezinzuzo okwabelwana ngazo), senze izinqumo eziguquguqukayo ezisekelwe ezidingweni zamakhasimende.
