A novel process for acid gas treatment apparatus and

The present invention provides a novel process for the acidic gas treating means and the acidic gas treating process of the two-phase gas-liquid countercurrent absorption reaction with NaOH solution as absorption liquid, gas production process of NaHS acid, a reaction product of the process and two liquid reaction product solution from the recycling. Two to three reaction solution as a reaction generated liquid absorbent to MDEA absorption liquid reaction solution as four, to achieve the purpose of replacing the CO2 absorbed H2S, CO2 reduction in the absorption of acidic gas, liquid products to reduce Na2CO3, NaHCO3's amount, to prevent crystallization, assurance means longer period. An acidic gas treating process of the present invention is simple and can achieve the dual goals gas purification and recycling acidic contaminants.
