ION Engineering has announced that it has successfully completed a six-month demonstration of its carbon capture system at the CO2 Technology Center Mongstad (TCM) in Norway.
During the TCM campaign, ION conducted over 150 individual experiments, testing its system on residue fluid catalytic cracker (RFCC) gas from Statoil's refinery. This sample closely resembles the CO2 concentration of the flue gas produced in coal-fired power plants. It also tested on flue gas from TCM's combined heat and power (CHP) plant, which is fuelled by natural gas.
ION's proprietary Advanced Liquid Absorbent System (ALAS) is comprised of a liquid absorbent, process technology, and the company's newest analytical technology, a Multicomponent Liquid Analyser, (MLA), which is capable of near-real-time compositional analysis of the liquid absorbent.
ION's ALAS campaign captured over 90% of the CO2 during steady-state testing from both the refinery and natural gas-fired flue gases with CO2 product purity of greater than 99%.
On the CHP flue gas, the ALAS required significantly less energy when compared with the industry-standard 30% MEA solvent previously tested at TCM—and with minimal solvent loss and emissions. ION also conducted the first successful field tests of two of its MLA devices and validated their performance when compared to traditional wet laboratory analyses. By the end of the campaign, ION had captured over 14 000 t of CO2, the equivalent of removing nearly 3000 vehicles from the road.
ION's CTO, Dr. Erik Meuleman, commented: "The TCM campaign has proven that ION's Advanced Liquid Absorption System is capable of successfully capturing over 90% of CO2 from refinery flue gas and natural gas, with low emissions and energy requirements." Meuleman also praised the first successful tests of the company's MLA: "Our technical team installed, tested, and verified the operation of our breakthrough MLAs. The analysers are a total game changer, providing near real-time composition analysis of the liquid absorbent, which streamlines the operation of the entire plant and reduces operating costs."
The International Energy Agency (IEA) has conclusively determined that there are no other practical alternatives to the use of carbon capture technology to achieve deep decarbonisation and the requisite CO2 reductions under the international Paris Agreement.
After six months of testing, ION's CEO Dr. Buz Brown concluded that "TCM has proven to be an excellent facility operated by very experienced engineers, providing an endless pool of invaluable data. The collaboration was simply fantastic. We now feel extremely comfortable designing and building commercial CO2 capture plants utilising our Advanced Liquid Absorption System."
Funding for ION's multi-phase project, over US$25 million in total, was provided by the US Dept. of Energy's NETL, with significant in-kind contributions from TCM. The first phase of the project was conducted at the National Carbon Capture Center in Wilsonville, Alabama, where ION successfully demonstrated its capture system on coal-fired flue gas.
