TAQA North is bringing their 1960’s gas plant into the 21st century. The traditional energy producer has re-vamped the Crossfield, Alberta facility with a new solution for acid gas, improving their production efficiency and reducing GHG emissions.
The East Crossfield Gas Plant generates sweet natural gas, which results in a byproduct of acidic gas. In the past, the plant disposed of the byproduct by making sulphur from the acid gas stream. They would also burn the remaining acid gas with a fuel mixture. This disposal method resulted in over 100,000 tonnes of annual GHG emissions from the Plant.
To improve their environmental footprint, TAQA embarked on a $30 million project to convert the Crossfield Plant to Acid Gas Injection. Now the plant inserts acid gas into a well 2.7 kilometres underground. This means they are no longer creating sulphur or using supplemental fuel gas. The completed project has reduced GHG emissions in the facility by 50 per cent.
The project received $10 million from ERA’s Industrial Efficiency Challenge. Launched in March 2018, the Industrial Efficiency Challenge was an open call to industrial facilities—Alberta’s most energy-intensive, trade-exposed industries—to implement new technologies that reduce emissions and operating costs. Technology like Acid Gas Injection can help Alberta’s industry adapt to new energy regulations and reduce GHG emissions and operating costs.
