Need: In 1972, PRCI Project PR-15-61 was initiated to measure exhaust emissions from stationary reciprocating gas engines and gas turbines used in natural gas compressor stations. Emission rates of oxides of nitrogen (NOx), hydrocarbons (HC), and carbon monoxide (CO) were measured from 59 reciprocating gas engines and nine gas turbines. During and subsequent to 1972, the PRCI laboratories and various PRCI member companies conducted emissions measurements. In 1978, PRCI Project PR-15-92 was initiated to conduct additional emissions measurements. That project involved 55 reciprocating gas engines and 11 gas turbines. All of those data were included in the May 1980 revision to the compilation of emissions data. Subsequent to the May 1980 revision, additional emissions measurements were conducted under PRCI Projects PR-15425 and PR-15-613, and emissions data were obtained from gas transmission companies and gas engine manufacturers in PR-15-613. These additional data are included in this 1988 reissue of the compilation.
Result: The emissions data presented in this data book have been obtained from projects conducted or sponsored by the Pipeline Research Committee of the Pipeline Research Council International (PRCI), individual PRCI member companies, or gas engine manufacturers. Data included are from in-use reciprocating engines and gas turbines that have been in-service for anywhere from less than a year to one or more decades. These data are generally presented as received. Editing has been limited to omitting data for entire tests only where the data are obviously in error and to identifying specific erroneous or questionable items within a test.
Benefit: The primary purpose of this compilation of emissions data is to assemble all of the available pertinent emissions data into a single, easy-to-use source for use by the PRCI member companies.
