Monoethanolamine (MEA) is used as a baseline solvent, which is commonly used in post-combustion carbon capture studies to compare the performance of proprietarily-developed amines and other CO2 removal processes. TCM, in cooperation with Aker Solutions, has been operating the amine plant since August 2012. Now, for the first time, TCM has completed large scale testing of the performance of the MEA solvent system on gas-fired emissions sources, which will be shared openly.
Speaking from the ARPA-E Energy innovation Summit, Washington DC, Olav Falk-Pedersen, Business Development Manager, CO2 Technology Centre Mongstad, said:
“We are excited to have completed this exciting testing phase at TCM. MEA is a widely used solvent by companies for benchmarking and improving their technology. So by thoroughly testing the MEA solvent system in the Amine plant, and openly sharing that information, we stand to help technologists around the world maximise the performance of their technologies and advance the CCS industry on a major scale.”
MEA has been used for many decades in the process industry including for production of CO2 for industrial purposes. Nowadays the MEA process acts as a baseline solvent, against which various technologies are benchmarked. The new tests include measurement and evaluation of a number of important parameters, such as energy consumption, emissions and degradation, within an accuracy of 2 -3%. The tests findings will be published in several scientific papers. Ultimately, the testing will provide a valid MEA baseline for a variety of CCS applications, both in the process industry and in power production.
Howard J. Herzog, Senior Research Engineer, MIT, said:
“I applaud TCM for their efforts in advancing CCS technology. Not only are they breaking new ground by the size of their capture plant, the fact that they will make their test results public is extremely important in enabling future improvements.”
Olav Falk-Pedersen, Business Development Manager, CO2 Technology Centre Mongstad, added:
“Any gas-fired CCS project will be very interested in the results of the MEA testing at TCM. The second dash for gas is locking unabated natural gas into the energy mix for the foreseeable future. Now the big question is how can the oil & gas industry adopt CCS, to maximise future gas profits, whilst simultaneously mitigating carbon emissions? Demonstration of CO2 capture from natural gas-fired power plant exhaust, at a considerable scale, is absolutely vital to answering that question.”
TCM’s MEA tests are being performed with 30 and 40 wt.% aqueous MEA solutions and with exhaust gas from the natural gas fired heat and power plant as an exhaust gas source. The MEA test will provide a new and important baseline from an industrial size facility. TCM’s industrial-scale laboratory collects a vast amount of data from more than 4,000 measuring points connected to online instruments. The lab tests a large number of samples each day, providing vital information from the tests performed at TCM. Instruments and sampling systems have been successfully verified and optimized, which is an important achievement for technology development and verification of CCS technologies.

About Technology Centre Mongstad
Technology Centre Mongstad (TCM) is the world’s largest and most advanced facility for testing and improving CO2 capture. TCM is a joint venture set up by the Norwegian state (75.12 %), Statoil (20 %), Shell (2.44 %) and Sasol (2.44 %). It aims to increase knowledge on carbon capture technologies, in order to reduce technical and financial risk, and accelerate the development of qualified technologies capable of wide scale international deployment.
The center comprises two CO2 capture plants each with a capacity to capture approximately 80,000 tons of CO2 from the nearby refinery or 20,000 tons from a gas fired power plant. In addition the center has available space and infrastructure to sustain the next generation technologies to be tested in the future. More information on TCM can be found at http://www.tcmda.com .
