Mitsubishi Heavy Industries (MHI) has concluded an agreement to license technology for its flue gas carbon dioxide (CO2) capture plant to PJSC Metafrax, a major Russian chemical company.
Tokyo/Japan — Metafrax will use recovered CO2 to produce ammonia, urea, and melamine from the byproducts of a methanol plant. The plant will provide recovery capacity of 1,200 tonnes per day, and will be installed at a facility in Perm, located on the western side of the Ural Mountains, scheduled for completion in 2021.
MHI received the order through Casale, a Swiss engineering firm, which obtained a contract from the Russian company for engineering, procurement and construction management (EPCm) of the overall ammonia production, CO2 capture, and urea and melamine production facilities. MHI will grant a technology license for CO2 recovery technology to Casale, which will sublicense it to Metafrax.
Ammonia will be synthesized by combining surplus hydrogen from the existing methanol plant with nitrogen from a newly constructed air separation plant. Urea and melamine will be then produced from CO2 recovered from flue gas emitted by the methanol plant. The facility will have capacity to produce 894 tonnes per day of ammonia, 1,725 tonnes per day of urea, and 40,000 tonnes per year of melamine.
Metafrax is the largest producer of methanol in Russia, with current production capacity of 3,375 tonnes per day, an increase of 35 % from 20 years ago.
MHI's flue gas CO2 capture technology, known as the KM CDR Process, uses an advanced absorption solvent (KS-1) jointly developed with Kansai Electric Power to achieve reductions in energy consumption compared with earlier methods. Since 1999 this technology has been adopted at 13 plants worldwide to capture CO2 from flue gases of steam reformers and boilers fired by natural gas, heavy oil or coal at chemical plants.
In addition to the production of urea, MHI's flue gas CO2 capture technology can be used for a wide range of applications, including chemical applications such as production of methanol and dimethyl ether (DME), capture and storage of CO2 generated by thermal power plants and other facilities, and enhanced oil recovery (EOR), a method of increasing crude oil production by injecting CO2 into oil reservoirs with declining productivity.
