The equipment is used to separate the CO2 from the other flue gases, enabling the majority of the CO2 emissions to be captured. The captured CO2 is used in part to support enhanced oil recovery (EOR) at local oil fields, improving circular practices. What is not used for EOR is permanently sequestered.
Prior to implementing carbon capture technology, the conventional coal-fired power plant was emitting approximately 1.3 million tonnes of CO2 each year. Today, the facility continues to generate enough electricity to power approximately 100’000 Canadian homes while reducing overall emissions from the plant.
Beginning 2025, carbon capture at the Boundary Dam power plant will rely on Sulzer’s technology, MellapakCC and MellaTech.
According to Sulzer, this technology has been developed to deliver capture efficiency at the lowest specific pressure drop. This results in lower energy consumption, offering gains in overall performance. With the local cost of electricity at approximately 20 Canadian cents per kWh, a pressure drop reduction of 10 mbar can save nearly CAD$ 500’000 annually for a 115 MW coal-fired power station.
Sulzer’s executive chairwoman Suzanne Thoma said: “As governments, industry and local communities around the world strive to reduce emissions, they are still challenged to meet the energy demands of their communities. Our solutions serve to bridge these competing requirements by reducing emissions, enabling recycling and circularity, and improving operational efficiency.”
