Hnathawh dan tur principle
Natural Gas Liquefaction Plant hnathawh dan hi core step pasarih angin a tawi zawngin kan sawi thei a, chungte chu: raw gas compression → pretreatment (dehydration, desulfurization) → hydrocarbon rit tak tak lakchhuah → mercury lakchhuah → cryogenic liquefaction → LNG dahkhawm → product output
Raw gas compression a awm chuan:Raw natural gas (a tlangpuiin 0.5-5.0 MPa-ah) chu compressor hmangin 4.0-7.0 MPa-ah compress a ni a, chu chuan a hnua tihthianghlim leh liquefaction neih theihna tur pressure condition a siam a ni.
A hmaa enkawl (dehydration, desulfurization): 1.1.Compressed raw gas chu pretreatment system ah a lut a. Dehydration (molecular sieves hmanga) hian tui awm zat chu 1 ppm hnuai lamah a tihhniam (liquefaction laiin ice siam loh nan); desulfurization (amine absorption emaw adsorption hmanga) hian hydrogen sulfide leh organic sulfur a paih chhuak a, total sulfur chu 50 ppm hnuaiah a tihhniam (equipment corrosion leh catalyst poisoning ven nan).
Hydrocarbon rit tak tak paih chhuahna:Pretreated gas chu fractionation tower chhungah a lut a, hydrocarbon rit tak tak (ethane, propane, butane, etc.) te chu boiling point danglamna hmangin a then a, feed gas chhunga hydrocarbon rit awm zat chu 0.1% hnuai lam a nih theih nan (liquefaction laiin solidification a awm loh nan).
Mercury lakchhuahna:Gas chu mercury adsorption tower (sulphur-impregnated activated carbon-a khat) kaltlangin a luang a, chu chuan mercury awm zat chu 0.01 ug/Nm3 hnuai lamah a tihtlem (aluminum alloy heat exchanger-te a chhe loh nan).
Cryogenic hmanga tui chhuah (cryogenic liquefaction) a ni.Natural gas thianghlim chu liquefaction system-ah a lut a (technology hman tlanglawn tak chu C3/MRC, AP-X, emaw mixed refrigerant cycle te hi a ni). Heat exchanger hrang hrangah multi-component refrigerant (nitrogen, methane, ethane, propane, etc. atanga siam) hmangin heat exchange a paltlang a, zawi zawiin ambient temperature atanga -162℃thlengin a lum a, gas atanga liquid LNG ah a inthlak thin.
LNG dahkhawmna hmun:Liquefied natural gas hi insulated cryogenic storage tank-ah (-162℃leh atmospheric pressure hnaihah) dah a ni a, hei hian evaporation loss a tihtlem phah a ni.
Product siam chhuah: 1.1.LNG hi storage tank atanga loading station-ah pump luh a ni a, chumi hnuah LNG carrier emaw tank truck-ah phurh luh nan phurh luh a ni. Storage process-a evaporated gas (BOG, boil-off gas) chu lakchhuah leh recompressed a ni a, liquefaction system-ah emaw fuel atan emaw hman nawn leh a ni.
