The possibility of extensive SCC in natural gas treatment plants is of obvious concern to the gas transmission industry. As a result, PRCI initiated a research project at Southwest Research Institute (SwRI) to investigate the SCC susceptibility of carbon steels in MEA and DEA solutions typical of amine solutions used in natural gas treatment plants. The primary objectives of the project were: to determine the parameters responsible for cracking; and to determine modifications to plant equipment an&or process chemistry that might be used to control SCC in natural gas treatment plants.

The possibility of extensive SCC in natural gas treatment plants is of obvious concern to the gas transmission industry. As a result, PRCI initiated a research project at Southwest Research Institute (SwRI) to investigate the SCC susceptibility of carbon steels in MEA and DEA solutions typical of amine solutions used in natural gas treatment plants. The primary objectives of the project were: to determine the parameters responsible for cracking; and to determine modifications to plant equipment an&or process chemistry that might be used to control SCC in natural gas treatment plants. This report describes the factors responsible for stress corrosion cracking (SCC) of steels in natural gas treatment plants using ethanolamine solutions to remove acid gases from natural gases; and to determine modifications to plant equipment and/or process equipment that might be used to control SCC in natural gas treatment plants.
