Tuam Tshoj Evaporative Crystallizer Hoobkas - MDEA desulphurization skid rau natural gas kho - Rongteng

Kev piav qhia

MDEA desulphurization (desulfurization) skid, tseem hu ua MDEA sweeting skid, yog ib qho khoom siv tseem ceeb hauv cov roj purifying lossis natural gas conditioning.

MDEA desulfurization skid rau cov nkev roj yog ib txwm tau txais thaum cov pa roj carbon sulfur ntawm cov pa roj yog qhov siab, thiab thaum xaiv tshem tawm H2S yog xav tau kom tau txais cov roj acid uas tsim nyog rau Claus cog kev ua, thiab lwm yam uas tuaj yeem xaiv tshem tawm H2S; Thaum tshem tawm H2S thiab tshem tawm ntau npaum li cas ntawm CO2, MDEA thiab lwm yam cawv (xws li DEA) tuaj yeem siv los ua txoj kev sib xyaw amine;

Txheej txheem

Tom qab cov khoom thiab cov kua impurities raug tshem tawm los ntawm cov pa roj los ntawm cov khoom sib cais thiab lim cais, cov roj pub yog desulphurized nyob rau hauv lub ntab valve ntauwd. Methyl diethanol (MDEA) tov yog siv los ua desulphurizer hauv ntauwd.

Tom qab tshem tawm ib qho me me ntawm MDEA kua ua npuas ncauj los ntawm cov roj los ntawm cov kua dej ntub dej cais tawm, cov roj ntub dej nkag mus rau lub cev qhuav dej ntauwd.

TEG yog siv los ua kom lub cev ntub dej ntub dej hauv cov pej thuam thiab cov roj qhuav los ntawm lub cev qhuav dej ntauwd yog siv. Natural gas yog siv los ua cov khoom lag luam tsim nyog rau kev xa tawm.

MDEA cov kua nplua nuj nyob rau hauv desulfurization ntauwd yog flash evaporated kom tshem tawm cov hydrocarbons thiab lim los ntawm cov ntxaij lim dej. Tom qab ntawd nws yog cua sov los ntawm chav kom rov tsim cov kua dej tsis zoo MDEA, uas tau muab tso rau hauv desulfurization ntauwd rau cyclic desulfurization.

Cov roj av los ntawm MDEA nplua nuj kua flash raug tshem tawm los ntawm cov kua qaub-dej cais, thiab cov tshuaj MDEA sib cais tau muab tso rau hauv ntauwd desulfurization. TEG nplua nuj kua siv nyob rau hauv lub cev qhuav dej ntauwd yog rhuab kom regenerate tsis zoo TEG tov los ntawm distillation kem, flash tank thiab lim. Nws yog pumped mus rau lub dehydration ntauwd rau cyclic dehydration.

Tom qab txhaj H2S roj rau hauv cov kua qaub cia tank ntawm qhov chaw sib cais ntawm cov kua qaub dej cais, nws yog preheated nyob rau hauv cov tshuaj tiv thaiv rauv thiab reacts nrog cov cua nqus los ntawm cov cua compressor rau daim ntawv SO2, uas reacts nrog rau cov H2S ntxiv rau tsim elemental leej faj, thiab ces tau sulfur tom qab txias.
