Onye nyere LNG Plant | Nkọwa ihe ndi eji eme ihe nke gas nke e mechie ihe nke ọkụ

Ngwaọrụ LNG:

Iji ihe mmiri dị iche iche na ihe mmiri nke hydrocarbon nke ukwu imejọ. Ihe mmiri nke gas nwere ike itolite na cold box wee koola tupu a haa na heavy hydrocarbon separator. Ebe a mere ya bụ liquid phase, a ga-eji ya na scrubbing tower. Site na distillation na scrubbing tower, a mara light natural gas na akwara ya na main heat exchanger ka kooluo. N'ikpeazụ koola ya na oche mpaghara ma si na ya na separation tank. Gas phase eteghị na main heat exchanger ka kooluo, liquefaction, na subcooling, mgbe ahụ koola ya wee pia LNG tank trucks site na loading arms. Liquid phase eteghị na akwa nke scrubbing tower site na circulation pump dị ka reflux liquid. A mara komponente nke hydrocarbon na akwa nke scrubbing tower, a throttled ya wee si na ya na mixed hydrocarbon storage tank. Otutu nke flash gas site na mixed hydrocarbon tank a ji ya dị ka fuel gas maka thermal oil, ebe ndị ọzọ baa na inlet nke raw gas compressor.

·Ihe Obla:

Ikwesị nke ihe omume a bụ na-eme ka mkpuchi mmiri iri na ikwusi ikwu. Ncheta propane na mkpuchi refrigerant dị egwu enwere ike inye ngwaọrụ maka mkpuchi dị elu, na-amalite nkwụsịta dị ukwuu nke energy liquefaction. Site na teknụzụ pụrụ iche nke hydrocarbon, ndịbe oke dịka ethane na propane nwere ike imejụ ebe ha (imejụ ebe >90%), na-amalite obere ego nke njikwa. Na-adaba, ịkpatụ ihe ndọpụta dị elu si mee ka LNG dị mfe ma ọ bụrụ na ngwaọrụ dị mma, na-emekarị maka njikwa ihe omume dị mma.
