Keyera Corp. has had to shut down its natural gas Alliance Pipeline in Western Canada due to a contamination of poisonous hydrogen sulphide gas, which leaked into the system.
The Alliance Pipeline – which usually supplies a fifth of the US Midwest gas – had stopped once it reached southeastern Saskatchewan.
Comments from Keyera
The company stated that there was “a brief operational upset during maintenance activities on the morning of 5 August at its Simonette gas plant, located 60 km southwest of Valleyview, Alta… [where] gas that did not meet sales gas specifications entered the Alliance Pipeline system.”
Plans to flare
The company has planned to dispose of the affected natural gas by flaring it. This will take place in Saskatchewan at its Alameda compressor station. Additionally, the company has stated that there will be no risk to the environment or human health.
