New test campaign started at TCM, Mongstad
The main objectives of TCMs MEA campaign are to increase learning and reduce technology risks with respect to scale-up and operation of a full scale generic capture plant.
- MEA (Monoethanolamine) 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 some of that information, TCM stands to help technologists around the world maximise the performance of their technologies and advance the CCS industry on a major scale, says TCMs technology manager Espen Steinseth Hamborg.
The new tests include measurement and evaluation of a number of important parameters, such as energy consumption, emissions, degradation, and plant operability. The test findings will be to a large extent 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.
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.
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, operated the amine plant from 2012-14. Now, for the second time, TCM has embarked on a large scale testing of the performance of the MEA solvent system on gas-fired emissions sources, which will be to a large extent shared openly.
Based on experiences from the Aker Solutions’ and TCM’s previous MEA campaign carried out in the period from November 2013 to February 2014, some areas of the amine plant need improvement and a further understanding. Following a major upgrade of gas phase measurement instrumentation analyzers, the following areas will be further investigated in the campaign;
• The plant design capacity should be better explored and explained
• The CO2 mass balances, optimized capture rates and specific energy consumption were uncertain to some extent and improvements should be expected with better and more advanced instrumentation
• The plant performance and effect of higher CO2 concentrations in the flue gas should be better explored and explained, intended for preparation of amine plants treating flue gases from future gas turbine installation with exhaust gas recycling
• Emission monitoring with advanced mass spectroscopy and fourier transform infrared spectroscopy should be further investigated
An improved MEA baseline and verification of the plant design capacity will also keep TCM as a recognised state-of-the-art test centre within solvent technology testing.

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 .
