Abstract
A process using a spray absorber bioreactor for the biocatalytic treatment of gases is disclosed. The process comprises the steps of contacting a gas phase, containing a gas to be treated, to a liquid phase containing a reactant capable of chemically reacting with and/or absorbing the gas, thereby producing a spent liquid phase containing at least one reaction product and a treated gas phase substantially free of the gas, such step being performed in the presence of biocatalysts suitable for catalyzing the chemical reaction between the gas and the reactant. The process is characterized in that the gas phase is contacted to spray droplets of liquid phase containing biocatalysts.
The use of droplets of liquid containing the biocatalysts enables to increase the gas-liquid interface, thereby allowing a high mass transfer rate of the gas to be treated from the gas phase to the liquid phase. These conditions of high mass transfer enable to transform the gas with a maximum reaction rate.
This process can advantageously be used for cleaning or purifying a gas phase containing a harmful gas. For example, it can be used for extracting CO2 from a gas emission.
