Tuam Tshoj Natural Gas Sweetening Unit Hoobkas - PSA decarbonization skid - Rongteng

Kev piav qhia

Natural gas decarburization (decarbonization) skid, yog cov cuab yeej tseem ceeb hauv cov pa roj purifying lossis kho.

Cov ntsiab lus ntawm cov pa roj carbon dioxide hauv cov qauv roj zoo yuav tsum tsis txhob ntau tshaj 3%. Thiab carbon dioxide nyob rau hauv dej tom qab cov hlau muaj zog heev corrosive. Yog tias tus nqi PH zoo ib yam, cov acidity piv ntawm cov pa roj carbon dioxide kuj siab dua, yog li qhov corrosion ntawm carbon dioxide ntawm steel kuj siab dua.

Siab viav vias adsorption (PSA) yog cov cuab yeej tshiab siv los cais cov roj sib xyaw hauv cov tshuab nqus adsorption. Piv nrog rau cov txheej txheem kev nqus tshuaj ib txwm siv, PSA thev naus laus zis yog kev lag luam zoo rau kev tshem tawm thiab rov qab los ntawm H2S thiab CO2 los ntawm cov nkev roj, thiab tau tsim muaj zog heev.

PSA roj sib cais tshuab muaj qhov zoo ntawm kev ua haujlwm yooj yim, tsis tshua muaj siab poob, lub cev qhuav dej thaum tshem tawm CO2, qis qis qis ntawm cov pa purified thiab dej, thiab cov khoom tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov pa xa tawm. PSA tuaj yeem siv rau CO2 concentration thiab xaiv desulfurization hauv cov pa roj.

Flow daim ntawv qhia

Adsorption tau ua nyob rau hauv siab thiab desorption tau ua nyob rau hauv lub siab txo. Vim tias lub voj voog adsorption luv luv thiab cov cua sov adsorption tsis tuaj yeem dissipated hauv lub sijhawm, nws tuaj yeem siv rau desorption. Yog li ntawd, qhov kub ntawm lub txaj adsorption tshwm sim los ntawm cov cua sov adsorption thiab desorption tshav kub hloov me ntsis, uas tuaj yeem suav tau tias yog txheej txheem isothermal. Ib qho ruaj khov adsorption txaj ua haujlwm, txawm hais tias nws yog qhov kub ntawm lub viav vias adsorption lossis siab viav vias adsorption, vim tias cov adsorbent yuav tsum tau rov tsim dua tshiab, cov adsorption tsis sib xws. Hauv kev lag luam, ob lossis ntau lub txaj adsorption yog siv, kom cov adsorption thiab rov tsim dua tshiab ntawm lub txaj adsorption yog ua los ntawm kev hloov pauv (lossis nyob rau hauv lem voj voog), los xyuas kom meej qhov txuas ntxiv ntawm tag nrho cov txheej txheem adsorption.

Functional nta

Kev ua haujlwm ntawm lub siab viav vias adsorption decarbonization skid yog 90%. Ntxiv nrog rau kev tshem tawm CO2, PSA thev naus laus zis tau siv dav hauv kev rov ua kom huv thiab huv ntawm H2, CH4, CO, CO2 thiab lwm yam roj av.
