Nbung n-gun jat ai ladat ni a matu, nitrogen generator ni a matu lata la mai ai lam lahkawng nga ai: nitrogen generator ni hte n-gun rawng ai hka ja ai jak ni. Lahta na hkrang shapraw ai lam ni a majaw, refrigerated dryers ni gaw tsi tsi ai lam hta n-gun rawng ai nbung system ni a matu grai n htap htuk ai.
Shawng nnan, pressure dew point gaw 2℃-7℃de sha du lu ai ; lahkawng, nbung{5}}cooled dryers ni a bungli galaw ai lam gaw grup yin katsi ai lam a matu ra kadawn ai lam ni nga ai. Ambient temperature grai law ai shaloi, prut prut ai nbung n-gun a kam hpa mai ai lam gaw n law ai; masum ngu na hta, system load gaw 30% hta npu ai shaloi, refrigerated dryer a nbung-hka garan ai a n-gun gaw grai n law ai majaw, nbung hte hka hkin gau de hka lim ai hka htung ni de du wa ai majaw, hka hkin gau npu na hka lim ai shara hpe hkrit tsang shangun ai, grau nna shana aten hta nbung n-gun grai yawm mat ai.

Kam mai ai dew point hte function hpe lu la na matu adsorption dryer hpe lata na matu, lawu na ahkyak ai lam ni hpe myit yu ra ai:
1. Flow rate
Adsorption dryer a lwi ai lam hpe madung hku nna, teng sha nga yang, nbung n-gun hpe jai lang ai hte maren, yawng hpe lata la ai, shing nrai, nbung compressor a nbung n-gun hte maren lata la mai ai. Ndai shara hta asan sha tsun ra ai gaw, 7bar pressure system npu hta desiccannt bai gram lajang na matu, hkap la ai dryer gaw, hka lim ai lam a 15% hpe madung hku nna jai lang ai. Ndai sum machyi ai lam ni hpe system hpe hkrang shapraw ai shaloi hkum tsup hkra myit yu ra ai.
2. Bungli galaw ai lam hta loi mi sha n-gun jaw ai
Gas a teng sha jai lang ai n-gun gaw nbung n-gun n-gun hta grau law ai shaloi, nbung n-gun hpe n-gun dat dat ai nbung n-gun yawm mat na re, dai gaw n-gun yawm mat na re, dai gaw adsorption dryer hpe n-gun hpe lai di shangun nna, pru wa ai dew point hpe n kam n sham hkra galaw ya na re.

3. Inlet nbung katsi ai
Nbung n-gun rawng ai nbung a hka n-gun gaw, hka kata na nbung katsi ai lam hte grai ni htep ai. Dai majaw, n-gun n rawng ai hka n-gun hpe 35℃lu ai. Inlet temperature gaw 50℃byin wa yang, hka n-gun rawng ai nbung hte htaw ai hka n-gun gaw kalang mi jan na re, dryer a galaw ai atsam hta grau ai. Adsorption a n-gun yawm mat nna, outlet dew point gaw -40℃hta yawm mat na re.
Adsorbent a atsam gaw nbung laru hte galai shai mat ai. Adsorption atsam gaw nbung katsi ai hte rau yawm mat wa ai. Alumina a matu, nbung katsi ai 50℃du ai shaloi, shi a hkap la lu ai atsam grai yawm mat ai. Dai majaw, madung hku tsun ga nga yang, adsorption dryer a standard inlet nbung katsi ai gaw 35℃re.
