The Acid Gas To Syngas (AG2S™) process is an innovative method for the production of syngas from carbon dioxide (CO2) and hydrogen sulfide (H2S).

The core technology consists in a Regenerative Thermal Reactor, which allows the oxide-reduction reaction:

2 H2S + CO2 + H2 + CO + H2O S2

Such reactor is feeded by a minimum injection of air or oxygen combined with carbon dioxide and hydrogen sulfide.

The gas undergoes a thermal treatment through the three reactor chambers: the Regenerative one, in which the gases are brought to 100 ° C, a cooling section and the last chamber in which the syngas is collected.

The process generates as main byproducts the elemental sulfur ( which finds application as raw material in different industry fields) and water. The AG2S™ technology also allows to further convert syngas into liquid chemical products, such as methanol, ammonia, dimethylether, synthetic fuels, olefins.

In addition to the above features, the AG2S™ technology has the advantage of being easily integrated, without major investments, in existing plants and to increase business performance.
