Zeolite molecular sieves ni gaw PSA (Pressure Swing Adsorption) ngu ai hka htung hpe shapraw ai hta ahkyak ai lit nga ai rai nna, shanhte a lata la ai hka htung ni hpe hka htung hpe atsawm sha jasan jaseng lu na matu ahkyak ai lam rai nga ai. PSA hydrogen hpe shapraw ai gaw hkum hkrang hku hkap la ai lam re, dai gaw molecular sieve adsorbent ntsa na gases amyu myu a hkap la lu ai atsam n bung ai hpe jai lang nna gas hpe garan ginhka ai ladat re.
Hydrogen hpe jasan jaseng ai lam gaw gara hku rai nga ai kun?
Hydrogen hpe hpaga lam hte n-gun atsam lam law law hta jai lang ai majaw, grau nna wan sau cell hte electronic hpaga lam ni hta jai lang ai majaw, shanhte hta grai ngang kang ai ra kadawn ai lam ni nga ai, san seng ai hydrogen sha ndai ra sharawng ai lam ni hpe hkap la lu na re.
Raitim, n-gun n rawng ai arung arai ni kaw na pru wa ai hydrogen hta hka n-gun hte n san seng ai arung arai ni law law lawm ai. Ndai hka hte n san seng ai arung arai ni gaw, n-gun dat ni hpe n-gun shayawm ya lu ai, n-gun dat ni hpe n-gun shayawm ya lu ai, jak ni hpe n-gun shayawm ya lu ai, shim lum lam hpe mung hkra machyi shangun lu ai. Dai majaw, hydrogen hpe jasan jaseng ai lam hte seng ai ladat ni gaw madung hku nna, hkyet mat ai hte n san seng ai hpe shapraw kau ai lam hpe madung tawn ai.
PSA Hydrogen hpe shapraw nna jasan jaseng ai lam
PSA hydrogen galaw shapraw ai lam gaw, hpaga lam hta jai lang ai hydrogen hpe jasan jaseng ai ladat langai mi rai nga ai. Grau nna, coke oven gas hte syngas (shingra wan n-gun hpe gram lajang ai, nhprang wan sau hpe galai shai ai) zawn re ai kayau kaya ai wan n-gun ni lawm ai hydrogen- hpe jasan jaseng na matu grai htuk manu ai.
PSA hydrogen jasan jaseng ai lam gaw, n-gun kaba ai npu na molecular sieves ni a laklai ai lata la ai atsam hpe jai lang nna, hydrogen hpe kayau kaya ai gas kaw na garan ginhka lu ai. Molecular sieve ni a pore size ni bung ai majaw, kaji ai n san seng ai molecule ni hpe rim la lu nna, kaba ai hydrogen molecule ni hpe shapraw lu ai.
Ndai size-n lawm ai ladat gaw hka hte awu asin ni hpe atsawm sha shapraw kau ya lu nna, ahkyak ai jai lang lam ni a matu htuk manu ai ultra-san seng ai hydrogen hpe shapraw ya lu ai. Bai nna, zeolite molecular sieve ni gaw ndai lam hta npawt nhpang nlung tai wa sai.
Pressure kaba npu hta, n san seng ai arung arai ni hpe hkap la nna, hydrogen gaw lai wa ai. N-gun n law ai/vacuum npu hta, molecular sieves ni gaw desorb (regenerate) galaw nna, n san seng ai hpe shapraw kau ya ai. Kalang lang n-gun hpe galai shai ai hku nna, san seng ai hydrogen hpe matut manoi lu la mai ai.
Hydrogen hpe jasan jaseng na matu Molecular Sieves ni
Inlet air hpe shawng-hpaji jaw ai lam: PSA system kata de kayau kaya nga ai nbung hka (hydrogen, hka n-gun, carbon monoxide, carbon dioxide, methane, nitrogen nbung, etc. lawm ai) n shang shi yang, wa hpe shawng shaw kau na matu 3A (sh) 4A zeolite molecular sieves (sh) activated alumina hpe lang ra ai.
N-gun kaba hte hkap la ai lam: N san seng ai arung arai ni (carbon monoxide, carbon dioxide, methane, nitrogen gas zawn re ai ni) hpe 5A zeolite molecular sieve hku nna hkap la lu ai, kalang lang 13X zeolite molecular sieve ni hpe mung hpawng de nna lang mai ai.
