Globaltechexport Ltd. is performing the design, manufacture, and supply of a Natural Gas Treatment Unit combined with a Gas Distribution Plant for the Chernogorsk TPP

Globaltechexport Ltd. has concluded a contract with Intertechelectro JSC for the design, manufacture, and supply of a Natural Gas Treatment Unit combined with a Gas Distribution Plant for the Chernogorsk TPP.

Chernogorsk TPP (24 Jichai 4000GF70-T gas reciprocating units with a capacity of 3.8 MW, electric power – 92 MW) is designed to provide reliable power supply to production facilities of the mining and processing complex based on the Chernogorsk copper-nickel ore deposit. The implementation of this project will be the first stage in the creation of the second-largest producer of palladium and platinum in Russia. The reserves of the Chernogorsk deposit are estimated at 131 million tons of ore containing palladium, platinum, rhodium, and gold. The designed production capacity of the first stage is 7 million tons of ore per year. The final product is copper and nickel concentrate with a high content of palladium, and platinum.

The Chernogorsk deposit is located in the Krasnoyarsk Territory, about 15 kilometers away from the city of Norilsk, which implies the hard-to-reach and severe conditions of the Far North with a long winter period and temperatures up to minus 56 °С. The Natural Gas Treatment Unit and Gas Distribution Plant, designed and supplied by Globaltechexport Ltd. fully comply with the highest requirements set for the Chernogorsk deposit equipment, including innovative, environmental, and climatic ones.

The equipment designed and supplied by Globaltechexport Ltd. will also have the advantage of its full operational readiness, compact layout containerized modules, and the highest possible degree of localization, close to 100 percent – according to the Decree of the Government of the Russian Federation No. 719, all core equipment (excluding the actuated shut-off valves, which are being purchased in a friendly country to accelerate the supply process with a duration of only 9 months) will be manufactured in Russia at the production facilities of Globaltechexport Ltd. and the facilities of our partners, proven over the years.

Such quotients became possible thanks to the meticulous work on import substitution, which was started by our company more than 5 years ago.

This approach once again proved its undoubted relevance since the put into operation of the Chernogorsk TPP was scheduled for 2024, but subsequently postponed to 2025 precisely due to the impossibility of equipment exportation from the unfriendly countries.
