Atmospheric emissions from the gas processing industry originate from compressor and pump engines, boilers for process heating and solution regeneration, and gas 'sweetening', the removal of hydrogen sulfide from the natural gas. This research effort concerned itself only with emissions from gas sweetening processes, primarily the amine type processes because of the widespread use of amine processes to the exclusion of other sweetening processes. Emissions from gas sweetening are the combustion products of the acid waste gases following their removal from the raw natural gas, and include sulfur dioxide with negligible emissions of particulates, nitrogen oxides, hydrocarbons and carbon monoxide. An emissions factor for SO2 was developed. SO2 emissions from gas sweetening are directly proportional to the mol percentage of H2S in the intake gas to the sweetening plant. Emissions are calculated by multiplying the whole number representing mol percent H2S by the factor 1685 to get pounds of SO2 per million cubic feet of intake gas sweetened. When the concentration of H2S is not known, a table is presented giving average H2S concentrations in gas produced in Air Quality Control Regions. New Source Classification Codes are proposed for the industry. A list of over 1,000 gas processing plants is presented with notes on their emissions.
