The technology licence will technically be granted to Swiss engineering company Casale SA, which will sublicense it to Russia’s largest methanol producer Metafrax, MHI said.
Casale SA has been contracted to undertake engineering, procurement and construction management (EPCm) for Metafrax’s facility, which will have the capacity to recover 1200 tonnes of CO2 per day. Metafrax will use the CO2 to produce ammonia, urea and melamine.
Ammonia will be synthesized by combining surplus hydrogen from an existing methanol production plant (pictured) with nitrogen from a new-built air separation plant. Urea and melamine will be produced from CO2 recovered from the methanol plant’s flue gas.
The facility in Perm, in Russia’s Ural mountains, is currently under construction and is planned to come online in 2021. It will be able to produce 894 tonnes of ammonia and 1725 tonnes of urea per day, plus 40,000 tonnes of melamine per year.
The technology captures CO2 from the flue gases of steam reformers and boilers fired by natural gas, heavy oil or coal. MHI said it uses an advanced absorption solvent jointly developed with Kansai Electric Power Co to achieve “substantial reductions in energy consumption compared with earlier methods”. It has been installed at 13 plants around the world since 1999.
In addition to chemical applications, MHI said the technology can be used for capture and storage of CO2 generated by thermal power plants and enhanced oil recovery (EOR).
