Iimveliso Inkcazo
Iplanti yokucoca irhasi yendalo (ekwaziwa njengeplanti yokucoca irhasi yendalo) sikhulu{0}}sesikali esipheleleyo seseti yezixhobo esebenza ngerhasi yendalo ekrwada ngokusekwe ekwahlukaneni kwenyama kunye neendlela zokucoca iikhemikhali.
Umgaqo wayo ongundoqo kukusebenzisa iiyantlukwano kwiipropati ezinjengendawo yokubilisa, ukunyibilika, kunye nomthamo we-adsorption phakathi kwe-methane kunye nezinye izinto (ezifana namanzi, i-carbon dioxide, i-hydrogen sulfide, kunye ne-hydrocarbons enzima) kwirhasi yendalo ekrwada ukususa ukungcola kunye nokwahlula ngeemveliso{0}}ngeenkqubo ezinjengokuphelelwa ngamanzi emzimbeni, i-desulfurization, kunye neqhezu.
Iyakwazi ukuvelisa{0}}igesi yendalo ekumgangatho ophezulu kwaye sesinye sezixhobo eziphambili kushishino lwerhasi yendalo.
Umgaqo wokusebenza
Inkqubo yokusebenza yeZiko loNyango lweGesi yeNdalo inokushwankathelwa njengamanyathelo amathandathu angundoqo: ukucinezelwa kwerhasi ekrwada → ukuphelelwa ngamanzi emzimbeni → ukuchithwa kwesulfurization/decarbonization → ukwahlukaniswa kwehydrocarbon → ukwaliwa kwenitrogen (ukhetho) → imveliso yemveliso
Uxinzelelo lwerhasi ekrwada:Irhasi yendalo eluhlaza (ngokuqhelekileyo kwi-0.5-5.0 MPa) ixinzelelwe kwi-2.0-10.0 MPa ngokusebenzisa i-compressor, ibonelela ngeemeko zokuhlukana nokuhlanjululwa okulandelayo.
Ukuphelelwa ngamanzi emzimbeni:Irhasi ekrwada ecinezelweyo ingena kwinkqubo yokuphelelwa ngamanzi emzimbeni (i-adsorption tower okanye i-glycol dehydration unit) ukuze isuse umphunga wamanzi (ukunqanda ukwakheka kwe-hydrate kunye nokuhlwa kwemibhobho), ukunciphisa umthamo wamanzi ube ngaphantsi kwe-100 mg/Nm³.
I-Desulfurization/decarbonization:Irhasi engenamanzi ingena kwinkqubo yokucoca ukuze isuse iikhompawundi zesulfure-eziqulathe iikhompawundi (ezifana nehydrogen sulfide) kunye necarbon dioxide. Iindlela eziqhelekileyo ziquka ukufunxwa kwe-amine (kwizityalo-ezinkulu) kunye nokufakwa kwe-adsorption (kwizityalo-ezincinci), ukunciphisa isalfure iyonke ibe ngaphantsi kwe-20 mg/Nm³ kunye ne-carbon dioxide ibe ngaphantsi kwe-3% (V).
Ukwahlulwahlulwa kweHydrocarbon:Irhasi emva kokususwa kokungcola ingena kwiyunithi yokuqhekeka (ngokuqhelekileyo i-cryogenic separator okanye i-distillation tower) ukwahlula ii-hydrocarbons ezinzima (i-ethane, i-propane, i-butane, njl.) ngokusebenzisa iiyantlukwano zamanqaku abilayo. Eli nyathelo lihlengahlengisa ixabiso le-calorific yerhasi yemveliso kwaye lifumana kwakhona irhasi yepetroleum engamanzi (LPG) kunye nepetroli yendalo.
Ukwaliwa kweNitrojeni (ukhetho):Ukuba igesi eluhlaza inomxholo ophezulu we-nitrogen (Inkulu okanye ilingana ne-5%), iyunithi yokulahla i-nitrogen (usebenzisa ukuhlukana kwe-cryogenic okanye ukuhlukana kwe-membrane) yongezwa ukunciphisa umxholo we-nitrogen ukuya ngaphantsi kwe-2%, ukuqinisekisa ixabiso le-calorific yegesi yemveliso.
Imveliso yemveliso:Irhasi yendalo esetyenzisiweyo (umthamo wemethane Enkulu okanye elingana nama-95%) ibalwa kwaye ihanjiswe kwimibhobho ukuze ithuthwe; zahlulwe -ziimveliso (ezifana nesalfure, iLPG, kunye nepetroli yendalo) zigcinwa okanye zisetyenziselwe ukusetyenziswa kwimizi-mveliso.

Izibonelelo zeemveliso zenkampani yethu
Kweli xesha langoku apho ugcino lwamandla kunye nokukhuselwa kokusingqongileyo kugxininiswa, uyilo olusulungekileyo ngundoqo wokuqinisekisa ukusebenza ngokufanelekileyo, ngokukhuselekileyo, kunye nokukhutshwa kwegesi yendalo ephantsi{0}}. Inkampani yethu ineqela leenjineli zobuchwephesha ezineminyaka engaphezu kwama-30 yamava ekusetyenzweni kwegesi yendalo, eqhelene nemigangatho eyahlukeneyo yasekhaya neyangaphandle kunye neenkcukacha, kubandakanya i-GB, API, ASME, ISO, kunye ne-EN. Sinikezela ngoyilo olulungelelanisiweyo olusekwe kukwakheka kwerhasi ekrwada (umzekelo, umxholo wesulfure, umxholo onzima wehydrocarbon) kunye neemfuno zabathengi (umzekelo, ukucaciswa kwemveliso, nge{8}}iimfuno zokubuyisela imveliso), ukulungelelanisa iindlela zenkqubo, ukukhetha izixhobo, kunye nokuhlanganiswa kwamandla (okufana nokubuyiswa kobushushu) ukunciphisa ukusetyenziswa kwamandla nge-5-10% xa kuthelekiswa noyilo oluqhelekileyo. Siyazilahla iitemplates ezisemgangathweni kwaye siqhube uyilo oluneenkcukacha kwiprojekthi nganye ukuze siqhelane neempawu ezithile zerhasi ekrwada.
Inkampani yethu isebenzisa ngokungqongqo inkqubo yolawulo lomgangatho we-ISO9001 kunye ne-ISO14001 inkqubo yolawulo lokusingqongileyo kuwo wonke umjikelo wobomi beprojekthi, ukuyila, ukuyila, ukuthenga, ukwakhiwa kunye nokugunyazisa. Ngexesha lesigaba soyilo, ukulinganisa inkqubo kusetyenziselwa ukuqinisekisa ukusebenza kakuhle kokwahlula kunye nokusetyenziswa kwamandla; izixhobo eziphambili (izicinezeli, iinqaba zeadsorption, izitshintshi zobushushu) zihlolwa{3}}zeqela lesithathu ukuqinisekisa ukuthotyelwa kwemigangatho; ulwakhiwo lulandela iinkqubo ezingqongqo ze-welding (kunye nesatifikethi se-WPS/PQR) kunye -novavanyo olungonakalisi (UT, RT, PT) kwiinqanawa zoxinzelelo; ugunyaziso luquka iiyure ezingama-72{7}}zovavanyo oluqhubekayo lokusebenza ukuqinisekisa ukucoceka kwemveliso, umthamo wokuqhuba, kunye nezalathi zokukhupha. Olu lawulo lucwangcisiweyo luqinisekisa umgangatho weprojekthi kunye nokuhanjiswa kwexesha.
Sithatha umgangatho wemveliso njengowona mgca wokuphila weshishini kwaye uzibophelele ekuziseni{0}}izityalo ezisebenza ngokuthembakeleyo. Isityalo ngasinye siphantsi kolawulo olungqongqo lomgangatho: ii-adsorbents kunye ne-catalysts zikhethwa kwiibrendi ezaziwayo kwihlabathi kunye nobomi benkonzo be-2{5}}5 iminyaka; iinqanawa zoxinzelelo kunye neepayipi zenziwa ngokuhambelana ne-ASME BPVC okanye i-GB 150 imigangatho, kunye nobomi boyilo obuKhulu okanye obulingana neminyaka eyi-20; isityalo esigqityiweyo sifezekisa izinga lempumelelo yokuqala ye-100% kunye nezinga lokusebenza oluzinzile lwe-Greater than or elilingana ne-95% (ngaphandle kokulondolozwa). Sinikezela ngamaxwebhu apheleleyo esiqinisekiso somgangatho, kubandakanywa izatifikethi zezinto eziphathekayo, iingxelo zovavanyo, kunye neencwadana zokusebenza.
Inkonzo esebenzayo emva{0}}yentengiso ibalulekile ekuqinisekiseni ukusebenza ngokuqhubekayo komzi-mveliso. Xa sifumana isicelo senkonzo, iqela lethu lobugcisa linika ingxelo yokuqala kwiiyure ze-12 (24/7) ngefowuni, i-imeyile, okanye inkomfa yevidiyo, kubandakanywa ukuxilongwa kwengxaki kunye nezisombululo zokuqala. Kwimiba ekude{6} enokusonjululwa (umzekelo, uhlengahlengiso lweparamitha), sikhokela isisombululo kwiiyure ezingama-24; kwiimfuno{10}}zokugcinwa kwesiza, iinjineli zithunyelwa kwiiyure ezingama-48 (zasekhaya) okanye iiyure ezingama-72 (zamazwe ngamazwe) emva kokuqinisekisa imfuno. Sikwabonelela ngeenkonzo zokukhusela rhoqo kunye nokubonelela ngeendawo ezisecaleni ukuze kuncitshiswe ixesha lokuphumla.
Inkampani yethu inokubonelela ngezixhobo zokulungisa igesi yendalo ngendlela ye-EPC (ubuNjineli, ukuthengwa, ulwakhiwo) iiprojekthi ze-turnkey, kunye nokubonelela ngeenkonzo zobuchwepheshe ezifana nokuphucula inkqubo kunye nesikhokelo sokusebenza. Kubathengi abaneemfuno zobonelelo ngerhasi zexesha elide, sikwabonelela ngemodeli yokusebenza yentsebenziswano (utyalo-mali oludibeneyo kwizityalo kunye nezibonelelo ekwabelwana ngazo), siququzelela ukhetho olubhetyebhetye olusekelwe kwiimfuno zabathengi.
