High quality Tuam Tshoj Skid Mounted LNG Cog Factory - Natural Gas Liquefaction Skid - Rongteng

Kev piav qhia

Liquefaction natural gas, luv luv hu ua LNG, yog condensing natural gas rau hauv cov kua los ntawm txias cov gaseous natural gas nyob rau hauv ib txwm siab mus - 162 ℃. Natural gas liquefaction tuaj yeem txuag tau ntau qhov chaw khaws cia thiab kev thauj mus los, thiab muaj qhov zoo ntawm cov nqi calorific loj, kev ua haujlwm siab, ua kom muaj kev sib npaug ntawm kev tswj hwm hauv nroog, ua rau muaj kev tiv thaiv ib puag ncig, txo cov pa phem hauv nroog thiab lwm yam.

Liquefaction yog qhov tseem ceeb ntawm LNG ntau lawm. Tam sim no, cov txheej txheem ntawm cov roj ntsha liquefaction feem ntau suav nrog cov txheej txheem cascade liquefaction, cov txheej txheem sib xyaw ua kua liquefaction thiab cov txheej txheem liquefaction nrog expander.

Cascade natural gas liquefaction txheej txheem siv cov ntsiab lus sib txawv ntawm cov tub yees nyob rau hauv ib txwm siab kom txo cov tub yees kub ib kauj ruam los ntawm kauj ruam kom ua tiav lub hom phiaj ntawm cov roj liquefaction.

Mixed refrigerant cycle (MRC) yog cov txheej txheem uas ntau tshaj tsib yam ntawm cov khoom sib xyaw ua ke, xws li C1 ~ C5 Hydrocarbons thiab N2, yog siv los ua cov kua dej ua haujlwm kom condense, evaporate thiab nthuav cov kauj ruam los ntawm kauj ruam kom tau txais cov tub yees ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab tom qab ntawd maj mam txias thiab liquefy ntuj roj. Cov txheej txheem sib xyaw refrigerant liquefaction tau muab faib ua ntau hom tub yees.

Cov txheej txheem liquefaction nrog expander yog hais txog cov txheej txheem ntawm cov roj liquefaction los ntawm kev siv cov tub yees txias kom paub txog qhov rov qab Claude cycle refrigeration nrog adiabatic expansion ntawm turbo expander.

Cov txheej txheem txheej txheem feem ntau suav nrog: pub roj siab tswj thiab ntsuas chav ntsuas, chav ntsuas roj purification thiab natural gas liquefaction unit, refrigerant cia system, refrigerant circulating compression system, LNG cia thiab chaw thau khoom.

Cov roj av nkag mus rau hauv qhov chaw nres tsheb thawj zaug dhau los ntawm kev tswj hwm lub siab thiab ntsuas qhov ntsuas, uas paub txog kev tswj xyuas lub siab thiab ntsuas cov khoom siv hluav taws xob tuaj; Cov pa roj carbon monoxide nkag mus rau hauv chav dej huv huv, qhov twg cov pa roj carbon monoxide yuav raug tshem tawm CO2, H2S tshem tawm thiab kho lub cev qhuav dej. MDEA txheej txheem yog pom zoo rau decarbonization thiab H2S tshem tawm, molecular sieve dehydration txheej txheem nrog peb pej thuam OR TEG cov txheej txheem dehydration raug pom zoo rau lub cev qhuav dej; Thiab Nws raug pom zoo kom siv rov qab thiab compressed BOG rau regeneration roj;

Purified natural gas mus rau hauv lub natural gas liquefaction unit, mix refrigerant (MRC liquefaction txheej txheem) yog pom zoo rau natural gas liquefaction; LNG liquefied yog khaws cia rau hauv lub tank, thiab cov txheej txheem khaws cia hauv huab cua thiab qhov kub thiab txias tau pom zoo rau LNG cia. Ib qho chaw nruab nrab ntawm qhov kub thiab txias cia tank yog nruab nrog BG compressor, thiab BOG compressor yog siv los nias BOG ua ntej nkag mus rau hauv molecular sieve dryer Regeneration, nyob ntawm lub twj tso kua mis cryogenic kom ua tiav kev teeb tsa.
