The capture of CO2:
It is currently accepted that human activiƟes are producing an excess of greenhouse gas (GHG). Among GHGS, CO2, is the most important in terms of quantity and overall impact.
This gas produced mainly by the burning of fossil fuels (coal, oil, gas), is released into the atmosphere in large quantities by human activities (transportation, housing and industry).
The capture of CO2 is an industrial technology used for the treatment of natural gas.
Many industrial processes of CCS exist on the market, having a specific application domain depending on the nature of the fumes to deal with (composition, temperature, pressure).
They all report to 3 main categories:
-Capture by post combustion, (recovery of the CO2 in the fumes of combustion).
-Oxyfuel (combustion with pure oxygen in order to have concentrated CO2 fumes).
-Pre-combustion (extraction of the CO2 at source by transformation of fossil fuel into synthesis gas).
