| Abstract: | Because of the feedstock changed in Chemical Fertilizer Plant, the CO2 recovery ratio is hard to satisfy NH3/CO2 balance. Thus, the Rectisol unit of ammonia plant was revamped. In the revamp, PSA technology was used to recover CO2 from the off gas from the 5 th stripper of CO2 regenerator of Rectisol unit to ensure the balance of NH3/CO2 in chemical fertilizer plant. |
