Combat climate change through technology

Technology centre rises to new heights

Construction activities at the new technology centre for CO2 capture at Mongstad (TCM) are proceeding according to plan. Soon the absorber towers will reach for the sky.

At the beginning of March, the slip pour will commence on Alstom's absorber tower. The tower will be 50 metres tall, including the chimney on the top.

Even taller, however, is the absorber tower on Aker Clean Carbon's capture facility. A whopping 62 metres straight up, and thus a new record at Mongstad. Pouring will start after Easter.

As this is written, work is underway on the foundations for the towers and the capture facilities. After Vassbakk og Stol completed the groundwork, AF-gruppen started the work on the foundation, concrete work, installing piping, constructing the cooling water inlet in the sea and a new electrical distribution station. Kruse Smith is carrying out the concrete work for Aker Clean Carbon, while Skanska is performing comparable work for Alstom.

Construction of the administration building and workshop has progressed the farthest, with walls and roof now in place. LAB is responsible for these buildings, and the company currently has more than 50 workers on the job. The 5000-metre administration complex will house several operations rooms to run the test facilities, as well as a workshop, laboratory, warehouse, etc.

Overall, the construction work is more than 25 per cent complete. After 800,000 working hours, there have been zero lost-time injuries and just one minor medical treatment injury.

A total of about 120 people are now working on the site at Mongstad, along with 500 engineers and technical specialists working from various locations for the various suppliers.
 
TCM will test two different technologies, from Aker Clean Carbon and Alstom, respectively, for capture of CO2 from two flue gas sources with different CO2 content. The objective of the testing is in part to qualify the technologies for large-scale cleaning of exhaust gas, while simultaneously developing cost-effective technology solutions.
 
The technology centre at Mongstad is the largest planned pilot project of its kind, with an annual capacity for handling up to 100,000 tonnes of CO2. The centre is scheduled to start operation in late 2011/early 2012.

Facts Technology Centre Mongstad (TCM)

The following companies own TCM:
Gassnova SF (77.56%)
Statoil ASA (20%)
A/S Norske Shell (2.44%)

TCM DA has its own management, which is responsible for operations and the testing programmes.

TCM is owned by potential end users of the CO2 capture technology. The goal is to bring in additional owners, and the South African energy company Sasol has signed a letter of intent concerning participation.

Statoil is the project manager and operator of the development phase. The construction work started in the summer of 2009, and the plan is to carry out the initial tests in late 2011/early 2012.

TCM has two exhaust gas sources: gas turbine exhaust from the new thermal power plant at Mongstad and exhaust from the refinery's cracker. The exhaust gas is relevant for a number of industrial processes, including gas and coal power plants.
TCM will include two CO2 capture technologies – one amine process and one chilled ammonia process.
 
The absorber towers will be used to test amine-based and chilled ammonia-based capture technologies. For CO2 capture after combustion, amines or chilled ammonia are used to absorb CO2. When the flue gas passes through the towers, most of the CO2 will bond with the amine or the chilled ammonia
