Ka ọnụ ọgụgụ ahịa nke ngwaahịa LNG na-agbanwe ka ọnọdụ ahịa si dị, mmepụta nke LNG kwesịrị imeghari ka ọ dabara na mgbanwe ahịa. Ya mere, a na-etinye ihe dị elu achọrọ maka ike nke ibu mmepụta na nchekwa LNG nke osisi LNG.
Iwu ibu mmepụta LNG
Iwu nke Mr compressor
MR compressor bụ centrifugal compressor. Enwere ike ịgbanwe ibu ya n'etiti 50 ~ 100% mgbe niile site na ịgbanwe ngwaọrụ ntinye valvụ ikuku na valvụ nloghachi nke compressor.
Nhazi ibu nke sistemụ tupu ọgwụgwọ
Ibu nhazi nke gas deacidification unit agaghị eru 100%. Dabere na njikwa nrụgide ahụ, enwere ike ịgbanwe ngwaọrụ sistemu tupu ọgwụgwọ ahụ n'ime oke ibu nke 50 ~ 110% ma mezuo ọkọlọtọ nke tupu ọgwụgwọ na nhicha.
Ibu iwu oke nke igbe oyi a na-atụ mmiri mmiri
Ibu nhazi nke igbe oyi a na-agba mmiri agaghị eru 100%. Mgbe ibu nke ngwaọrụ ahụ gbanwere site na 50% ruo 100%, ihe mgbanwe okpomọkụ efere na valvụ dị na igbe oyi nwere ike ịrụ ọrụ nke ọma ma mezuo ọnọdụ ọrụ nke ibu dị iche iche.
Na mkpokọta, mgbanwe ọrụ nke ngwaọrụ ahụ dum bụ 50% ~ 100%. Ndị ọrụ nwere ike ịgbanwe ibu nke ngwaọrụ ahụ n'ime oke a dabere na ọnọdụ ahịa nke ngwaahịa ahụ iji melite akụnụba ọrụ.
Mgbanwe ikike nchekwa nke tankị nchekwa LNG
Dịka mmepụta LNG si dị, olu tankị nchekwa anyị na-enye bụ mmepụta LNG nke ụbọchị iri, a pụkwara iji olu nchekwa nke tankị nchekwa ahụ gbochie mgbanwe ahịa.
Mgbanwe nke ihe mejupụtara gas nri
Mgbanwe nke ihe mejupụtara gas nri ga-eweta ihe ịma aka na ọgwụgwọ tupu a gwọọ ya na iwepụ ihe ọṅụṅụ.
Nzaghachi nke sistemụ tupu ọgwụgwọ gas nri na mgbanwe akụkụ
Nzaghachi nke decarbonization
Dịka ọnụọgụgụ carbon dioxide dị ugbu a si dị, anyị na-eji usoro amine MDEA iji decarbonize ma mee ka nhazi nke carbon dioxide dịkwuo elu ruo 3%. Ọtụtụ ahụmịhe injinia bara uru egosila na nhazi a nwere ike ịgbanwe agbanwe ọdịnaya carbon dioxide ma wepụ carbon dioxide ruo ọkwa nke 50ppm.
Mwepụ hydrocarbon dị arọ
Nnukwu hydrocarbons dị na gas sitere n'okike bụ neopentane, benzene, aromatic hydrocarbons na ihe ndị dị n'elu hexane nke na-emebi usoro cryogenic nke igbe oyi. Usoro mwepụ anyị na-agbaso bụ usoro mmịpụta carbon + usoro mmịpụta okpomọkụ dị ala, nke bụ atụmatụ mkpuchi nke nzọụkwụ abụọ na nke abụọ. Nke mbụ, a na-etinye hydrocarbons dị arọ dị ka benzene na aromatic hydrocarbons site na carbon arụ ọrụ na okpomọkụ ụlọ, mgbe ahụ a na-ejikọta ihe ndị dị arọ dị n'elu propane na - 65 ℃, nke na-enweghị ike iwepụ ihe ndị dị arọ dị na gas nri, kamakwa kewapụ ihe ndị dị arọ iji nweta hydrocarbons agwakọtara dị ka ihe na-esote.
Mmeghachi omume nke mmiri ịkpọ nkụ
Mmiri dị na gas sitere n'okike na-adaberekarị n'okpomọkụ na nrụgide. Mgbanwe nke ihe ndị ọzọ dị na gas nri agaghị enwe nnukwu mmetụta na mmiri dị n'ime ya. Ojiji nhazi mmiri na-ebelata mmiri zuru oke iji nagide ya.
Nzaghachi nke sistemụ liquefaction na mgbanwe akụkụ
Mgbanwe nhazi nke gas nri ga-ebute mgbanwe nke usoro okpomọkụ liquefaction nke gas eke. Site n'ịhazi oke nke refrigerant agwakọtara (MR) nke ọma, mgbanwe nhazi nke gas nri nwere ike ịgbanwe ruo n'ókè dị ukwuu.
