Project nominated for the Excellence in Low-carbon steel production Steelie Award 2022

The CO2 absorption systems installed in the DRI plants in San Nicolás de los Garza, Nuevo León (the Guerrero plant) and the Puebla plant eliminate or remove most of the CO2 contained in the exhaust-reducing gas at the reactor outlet (recycled gas).

The CO2 contained in the exhaust gas is removed in the absorber tower. At its outlet, the high CO2 content solution is heated and regenerated in the regeneration tower, where it releases the CO2 absorbed by the solution. This captured CO2 is sent to a third-party company, which processes it for sale.

The CO2 that for Ternium is a co-product of the process and that is released into the environment is purified by partner companies to give it a food grade and then use it in carbonated beverages, among other things.

In this way, Ternium creates a sustainable circle in which it takes care of the environment by preventing the release of CO2 into the atmosphere. At the same time, Ternium’s partners avoid importing this product, helping to reduce emissions in the country.
