(1) PSA-H2 Cog Adsorption txheej txheem
Feed Gas nkag mus rau ntauwd adsorption los ntawm lub hauv qab ntawm lub pej thuam (Ib tug los yog ob peb ib txwm nyob rau hauv lub xeev ntawm adsorbing). Los ntawm kev xaiv adsorption ntawm ntau yam adsorbents ib tom qab ib qho, cov impurities yog adsorbed thiab un-adsorbed H2 ntws tawm ntawm sab saum toj ntawm ntauwd.
Thaum txoj hauj lwm rau pem hauv ntej ntawm huab hwm coj hloov chaw (adsorption rau pem hauv ntej txoj hauj lwm) ntawm cov adsorption impurity mus txog rau qhov tawm tseg seem ntawm lub txaj txheej, tua tawm lub valve ntawm pub roj thiab lub qhov hluav taws xob valve ntawm cov khoom roj, nres adsorption. Thiab tom qab ntawd lub txaj adsorbent hloov mus rau cov txheej txheem tsim dua tshiab.
(2) PSA-H2 Cog Equal Depressurization
Tom qab cov txheej txheem adsorption, raws li cov kev taw qhia ntawm adsorption muab siab dua-siab H2 ntawm adsorption ntauwd mus rau lwm qhov qis siab adsorption ntauwd uas tau ua tiav kev tsim dua tshiab. Tag nrho cov txheej txheem tsis yog tsuas yog depressurization txheej txheem, tab sis kuj yog cov txheej txheem rau recovering H2 ntawm txaj tuag qhov chaw. Cov txheej txheem suav nrog ob peb zaug ntawm kev sib npaug ntawm kev nyuaj siab, yog li H2 rov qab tuaj yeem ua kom tiav.
(3) PSA-H2 Plant Pathwise Pressure Release
Tom qab sib npaug ntawm cov txheej txheem depressurization, raws li cov kev taw qhia ntawm adsorption cov khoom H2 nyob rau sab saum toj ntawm lub adsorption ntauwd tau rov qab los sai sai rau hauv txoj kev siab tso pa roj tank (PP Gas Buffer Tank), qhov no ntawm H2 yuav raug siv los ua cov khoom siv hluav taws xob ntawm cov adsorbent. kev nyuaj siab.
(4) PSA-H2 Cog Reverse Depressurization
Tom qab pathwise siab tso tawm txheej txheem, lub adsorption rau pem hauv ntej txoj hauj lwm tau mus txog qhov tawm ntawm lub txaj txheej. Lub sij hawm no, lub siab ntawm adsorption ntauwd yog txo mus rau 0.03 barg los yog li ntawd nyob rau ntawm adsorption adsorption tsis zoo, ntau npaum li cas ntawm cov adsorption impurities pib desorbed los ntawm adsorbent. Qhov thim rov qab depressurization desorbed gas nkag mus rau hauv lub tank gas buffer thiab sib tov nrog cov purging regeneration gas.
(5) PSA-H2 Cog Purging
Tom qab rov qab cov txheej txheem depressurization, txhawm rau kom tau txais kev rov ua tiav ntawm adsorbent, siv cov hydrogen ntawm txoj kev siab tso cov pa roj tank ntawm qhov tsis zoo ntawm adsorption los ntxuav lub adsorption txaj txheej, ntxiv txo qis qis, thiab cov adsorbent tuaj yeem ua tiav. regenerated, cov txheej txheem no yuav tsum tau qeeb thiab ruaj khov kom cov txiaj ntsig zoo ntawm kev tsim dua tshiab tuaj yeem ua kom ntseeg tau. Purging regeneration gas kuj nkag mus rau blowdown tail gas buffer tank. Tom qab ntawd nws yuav raug xa tawm ntawm lub roj teeb txwv thiab siv los ua roj av.
(6) PSA-H2 Cog Equal Repressurization
Tom qab purging cov txheej txheem rov tsim dua tshiab, siv H2 siab dua los ntawm lwm qhov adsorption ntauwd kom rov ua kom lub adsorption ntauwd nyob rau hauv lem, cov txheej txheem no cuam tshuam nrog cov txheej txheem sib npaug-depressurization, nws tsis yog tsuas yog cov txheej txheem ntawm kev txhawb zog siab, tab sis kuj yog txheej txheem ntawm kev rov qab H2. nyob rau hauv lub txaj tuag qhov chaw ntawm lwm yam adsorption ntauwd. Cov txheej txheem suav nrog ob peb zaug ntawm cov txheej txheem sib npaug-repressure.
(7) PSA-H2 Plant Product Gas zaum kawg Repressurization
Tom qab ob peb zaug sib npaug ntawm cov txheej txheem repressurization, txhawm rau hloov lub adsorption ntauwd rau cov kauj ruam adsorption tom ntej tsis tu ncua thiab xyuas kom cov khoom purity tsis hloov pauv, nws yuav tsum siv cov khoom H2 los ntawm kev tswj lub valve kom nce siab ntawm adsorption ntauwd rau adsorption siab. maj mam thiab tsis tu ncua.
Tom qab cov txheej txheem, cov adsorption yees ua tiav tag nrho "adsorption-regeneration" lub voj voog, thiab ua rau kev npaj rau adsorption tom ntej.
