METHOD AND COMPOSITION FOR REMOVING ACIDIC CONTAMINANTS FROM GASES
First Claim
1. A PROCESS FOR REMOVING ACID GASES FROM A GASEOUS MIXTURE, SAID ACID GASES BEING SELECTED FROM THE GROUP CONSISTING OF CO2, H2S, HCN, CS2, COS, SO2 AND OXIDATION PRODUCTS AND SULFIDES OF METHANE, ETHANE, PROPANE AND BUTANE WHICH COMPRISES CONTACTING SAID MIXTURE WITH A SOLUTION, SAID SOLUTION COMPRISING 5 TO 40 WT. PERCENT OF AN ALKALI METAL SALT, SAID SALT SELECTED FROM THE GROUP CONSISTING OF POTASSIUM CARBONATE AND SODIUM CARBONATE AND A SYNERGISTIC PROMOTER SYSTEM COMPRISING AT LEAST ABOUT 7 WT. PERCENT OF AN AMINE BEING SELECTED FROM THE GROUP CONSISTING OF PIPERIDINE, DERIVATIVES OF PIPERIDINE, 1,6-HEXANEDIAMINE AND DERIVATIVES OF 1,6-HEXANEDIAMINE AND BORIC ACID, AND SAID BORIC ACID BEING PRESENT IN THE AMOUNT OF FROM 0.5 TO 5 MOLES OF BORIC ACID PER MOLE OF AMINE, AT TEMPERATURE OF 25 TO 200* C., AND A PRESSURE OF 5 TO 2,000 P.S.I.G. AND MAINTAINING SAID SOLUTION IN A SINGLE PHASE DURING SAID CONTACTING WHEREIN AT LEAST A PORTION OF SAID ACID GAS IS ABSORBED BY SAID SOLUTION.
