AMINE TREATING PROCESS FOR ACID GAS SEPARATION USING BLENDS OF AMINES AND ALKYLOXYAMINES
A PROCESS FOR ABSORBING HS AND CO FROM A GAS MIXTURE CONTAINING BOTH THESE GASES COMPRISES CONTACTING THE GAS MIXTURE WITH AN ABSORBENT COMBINATION OF (I) PRIMARY ABSORBENT COMPONENT COMPRISING A SEVERELY STERICALLY HINDERED TERTIARY ETHERAMINE TRIETHYLENE GLYCOL ALCOHOL OR DERIVATIVE OF SUCH AN ALC...

| description | A PROCESS FOR ABSORBING HS AND CO FROM A GAS MIXTURE CONTAINING BOTH THESE GASES COMPRISES CONTACTING THE GAS MIXTURE WITH AN ABSORBENT COMBINATION OF (I) PRIMARY ABSORBENT COMPONENT COMPRISING A SEVERELY STERICALLY HINDERED TERTIARY ETHERAMINE TRIETHYLENE GLYCOL ALCOHOL OR DERIVATIVE OF SUCH AN ALCOHOL AND (II) SECONDARY ABSORBENT COMPONENT FOR ACIDIC GASES COMPRISING A LIQUID AMINE SUCH AS METHYLDIETHYLAMINE (MDEA) MONOETHANOLAMINE (MEA) 2 AMINO 2 METHYL L PROPANOL (AMP) PIPERAZINE (PZ) DIETHANOLAMINE (DEA) TRIETHANOLAMINE (TEA) DIGLYCOLAMINE (AMINOETHOXYETHANOL DGA) AND DIISOPROPYLAMINE (DIPA) ANOTHER ETHERAMINE ALCOHOL OR DIAMINE. BY USING THE COMBINATION OF AMINE ABSORBENTS THE OVERALL SELECTIVITY OF CO PICKUP CAN BE MAINTAINED WHILE RETAINING GOOD HS SORPTION SELECTIVITY; THE SELECTIVITY OF THE COMBINATION FOR HS AND C02 MAY BE CONTROLLED OVER A RANGE OF GAS LOADINGS IN THE ABSORBENT. |
