Ukubuka Konke Kwephrojekthi

Le phrojekthi iyisiteshi sokuvuselela igesi se-LNG esisekelwe endaweni yezimboni eNigeria. Inqubo yayo eyinhloko isebenzisa uhlelo lokufudumeza amanzi oluvaliwe. Isebenza njengesikhungo esibalulekile sokuguqula amandla phakathi kwesitoreji se-LNG namapayipi abasebenzisi angaphansi komfula, iguqula ngempumelelo nangokulawulayo igesi yemvelo ewuketshezi e-cryogenic ibe uphethiloli wegesi oshisayo ohambisana nokushisa okuzungezile ngenqubo yokushintshana kokushisa okuzinzile, ihlinzeka ngokuhlinzekwa okuqhubekayo nokuthembekile kukaphethiloli ohlanzekile wokukhiqiza izimboni zasendaweni.

Izici Zomkhiqizo Oyinhloko Nezobuchwepheshe

1. Uhlelo Lokufudumeza Amanzi Oluvalayo Olusebenza Kakhulu

   Ingaphakathi lesiteshi liqukethe ama-vaporizer amanzi ahamba ngamayunithi amaningi, ahambisanayo, asebenzisa uhlelo lwamanzi oluvaliwe oluzimele njengendawo yokushisa. Lolu hlelo lunikeza izinzuzo ezihlukile zamandla okushisa alungisekayo kanye nokushisa kwegesi okuphumayo okuzinzile. Aluthinteki ukuguquguquka kwezinga lokushisa langaphandle kanye nomswakama, lugcina amandla okufudumeza aklanyelwe ngendlela eqinile ngaphansi kwanoma yisiphi isimo sezulu. Lokhu kuyenza ifaneleke kakhulu kubasebenzisi bezimboni abanezidingo eziqinile zokucindezela kanye nokushisa kokunikezwa kwegesi.

2. Umthombo Wokushisa Ohlanganisiwe kanye Nokulawula Ukushisa Okuhlakaniphile

   Lolu hlelo luhlanganisa ama-boiler amanzi ashisayo asebenza kahle kakhulu asebenzisa igesi njengomthombo oyinhloko wokushisa, ohlanganiswe nama-heat exchanger kanye nama-circulating pump sets. Uhlelo oluhlakaniphile lokulawula izinga lokushisa lwe-PID lulawula ngokunembile izinga lokushisa lokugeza amanzi, luqinisekisa ukulawulwa okunembile kwezinga lokushisa legesi eliphumayo le-vaporizer (ngokuvamile lizinze ngaphakathi kuka-±2°C). Lokhu kuqinisekisa ukusebenza okuphephile nokuzinzile kwamapayipi nemishini engezansi komfula.

3. Ukwehliswa Kokuphepha Okunezingqimba Eziningi kanye Nomklamo Wezimo Eziphuthumayo

   Umklamo uhlanganisa ukuphindaphinda komthombo wokushisa okuhambisana nezihibe ezimbili (ibhoyila enkulu + ibhoyila elindile) kanye nokusekela amandla okuphuthumayo (kwezinsimbi ezibalulekile kanye nezifunda zokulawula). Lokhu kuqinisekisa ukuthi uhlelo lungagcina ukusebenza okuphephile noma lufinyelele ukuvalwa okuhlelekile uma kwenzeka ukushintshashintsha kwegridi noma ukwehluleka komthombo wokushisa okuyinhloko. Uhlelo lunezikhiye zokuphepha ezakhelwe ngaphakathi ezinamazinga amaningi zokucindezela, izinga lokushisa, kanye nezinga, ezihlanganiswe nezinhlelo zokuthola igesi evuthayo kanye nezinhlelo zokuvala eziphuthumayo (ESD).

4. Umklamo Olungiselelwe Izimo Zegridi Ezingazinzile

   Ngenxa yokungazinzi kwegridi yendawo, yonke imishini ebalulekile ejikelezayo (isb., amaphampu amanzi ajikelezayo) isebenzisa ubuchwepheshe be-Variable Frequency Drive (VFD), enikeza amandla okuqala kalula kanye nokulungiswa kwamandla ukuze kuncishiswe umthelela wegridi. Uhlelo lokulawula luvikelwe yi-Uninterruptible Power Supplies (UPS), okuqinisekisa ukuqapha okuqhubekayo kokuphepha kanye nokulawula inqubo ngesikhathi sokucima kukagesi.

Usekelo Lobuchwepheshe Lwendawo kanye Nesevisi

Le phrojekthi igxile ekuhlinzekweni kwephakheji yenqubo yokufudumeza amanzi eyinhloko kanye nemishini, ukuqapha ukufakwa, ukugunyazwa, kanye nokuqeqeshwa kobuchwepheshe. Sinikeze ukuqeqeshwa okukhethekile kwethimba lemisebenzi yendawo elenzelwe lolu hlelo futhi sasungula indlela yokusekela yesikhathi eside ehlanganisa usizo lobuchwepheshe olukude kanye nempahla yezingxenye ezisele zasendaweni. Lokhu kuqinisekisa ukusebenza nokuthembeka kwesikhungo esikhathini sokuphila kwaso sokusebenza. Ukuqedwa kwalesi siteshi kunikeza iNigeria nezinye izifunda ingqalasizinda yamandla engazinzile kodwa isidingo esikhulu sokuzinza kokuhlinzekwa kwegesi ngesisombululo sokuvuselela igesi se-LNG esivuthiwe ngobuchwepheshe, esisebenza ngokuthembekile esizimele ezinkingeni zezulu zangaphandle.
