CO2 Capture Carbon Capture Technology in Cement Production to be Nearing Breakthrough?

Editor: Anke Geipel-Kern

Norway has startet a carbon capure pilot project in Cement Production. Aker Solutions' CO2 Capture Technology is picked by Norcem for Commercial-Scale Use in Cement Production.

Aker Solutions tells, that the company has won an order from Norcem for a feasibility study on the development of a commercial-scale carbon capture facility for use in cement production, the source of about 5 percent of global greenhouse gas emissions. If feasability study is sucessful, this will be the first carbon capture facility for use in cement production, the company says.

Tests are Succesfully Tested

The company will look at capturing as much as 400,000 tons of carbon dioxide a year at Norcem's cement plant in Brevik, Norway, using Aker Solutions' technology. The extended feasibility study will contain an overall design for the facility, including its utility systems, CO2 liquefaction and ship offloading as well as integration with the cement plant.

Aker Solutions' carbon capture technology has been successfully tested for 18 months at the cement plant using a mobile test unit. The tests show that the technology is cost-efficient, robust and flexible during various operating conditions at the plant.

"The promising results of this pioneering project show that our technology can be used to substantially reduce CO2 emissions," said Per Harald Kongelf, head of Aker Solutions in Norway. "We are very pleased that our technology has proven to be the most efficient for further developments in Brevik and we look forward to a continued collaboration with Norcem."

The work for Norcem is part of a feasibility study that will be submitted to Gassnova and the Norwegian Ministry of Petroleum and Energy by the end of May 2016. The Brevik plant has been nominated to become a national carbon capture and storage demonstration project in Norway by 2020.

"The collaboration with Aker Solutions will take Norcem an important step forward in the development of a commercial-scale capture plant in Norway," said Per Brevik, director of sustainability and alternative fuels at Norcem.

The parties agreed not to disclose the contract value.

Cost-Efficient Carbon Capture

Cement flue gas contains about 18 percent CO2 by volume. Initial studies have demonstrated that the carbon capture plant will be compact and cost-efficient. Heat integration studies have concluded that about half of the CO2 emission from the cement plant in Brevik can be captured by utilisation of waste heat from the cement production. Cost of heat supply is normally one of the highest operating cost factors for the capture plant, but for the Norcem plant the operating cost of heat will be almost zero.
