Hot potassium carbonate is used for absorption of carbon dioxide which present as impurity in natural gas, synthesis gas and coke oven gas. Hot potassium carbonate is modified by adding some catalysts and promoters along with it which is known as Giammarco- Vetrocoke process (G.V) the solution is called as G.V. Solution. The presence of carbon dioxide cause lowering the calorific value and affect the chemical reaction in which these gases going to participate for production of petrochemicals. By means of absorber using a suitable solvent based on the carbon dioxide (CO2) content in process gas operating parameters can be designed.

Carbon Dioxide Absorber |
Most famous chemical solvent used for CO2 absorption are:
N-FormylMorpholine
Diethanolamine(DEA)
MEA plus amine guard
Aqueous sodium carbonate

High Pressure Re-Generator |
The absorbed carbon dioxide is recovered and leaving the pure absorption solution for reuse in the process stream. Due to reversible reaction under pressure carbon dioxide is stripped out.
