Abstract: THE DISCLOSURE CONCERNS A PROCESS FOR REMOVING MERCAPTANS FROM FLUID STREAMS COMPRISING SAME , ESPECIALLY FROM HYDROCARBON GAS STREAMS, FOR EXAMPLE NATURAL GAS , SYNTHESIS GAS FROM HEAVY OIL OR HEAVY RESIDUES OR REFINERY GAS , OR ELSE FROM LIQUID HYDROCARBONS, FOR EXAMPLE LPG (LIQUEFIED PETROLEUM GAS ). THE INVENTION COMPRISES INTIMATELY CONTACTING THE FLUID STREAM IN AN ABSORPTION OR EXTRACTION ZONE WITH A SCRUBBING LIQUOR COMPRISING AT LEAST ONE ALIPHATIC ALKANOLAMINE OF 2-12 CARBON ATOMS , THE AMOUNT OF WASH LIQUOR BEING SUPPLIED TO THE ABSORPTION OR EXTRACTION ZONE BEING SUFFICIENT TO REMOVE AT LEAST CO2 AND H2S ESSENTIALLY COMPLETELY FROM THE FLUID STREAM , AND SEPARATING THE SUBSTANTIALLY DECONTAMINATED FLUID STREAM AND THE CONTAMINATED WASH LIQUOR AND DISCHARGING THEM FROM THE ABSORPTION ZONE . THE SUBSTANTIALLY COMPLETE REMOVAL OF CO2 AND H2S IS ACCOMPANIED BY THE REMOVAL FROM THE GAS STREAM OF A VERY LARGE PORTION OF THE MERCAPTANS AS WELL , WITHOUT A SIGNIFICANT FRACTION OF THE HYDROCARBON GASES DISSOLVING IN THE WASH LIQUOR.
