Downflow Gas Contactor (DGC) Technology
A novel mass transfer reactor for contacting liquids and gases

Maturity stage
TRL 9 / CRI 2 - Commercial Trial Small Scale
The DGC reactor has several uses: carbon capture for CO2 removal from any gaseous stream, effluent treatment (wastewater), and chemical reactions. The system consists of a column which can be constructed to specific requirements such as dimension and configuration. At the top of the column, a gas and a liquid stream enter the reactor simultaneously through an specially designed entry (SDI). Both streams enter the reactor as a high velocity jet stream. This produces a gas dispersion that enhances mass transfer from the gas to the liquid which occurs at the interfacial area (where the gas and liquid meet). The intense turbulence and shear at the interface results in efficient gas-liquid mixing with minimal energy expenditure.
The Environmental Benefits
- •In CO2 capture, DGC can remove 99% of CO2 from biogas.
- •Size of reactor is 30-60% smaller than conventional bioreactor used in effluent treatment.
The Financial Benefits
- •10-30% lower OPEX for the three applications (CO2 capture, effluent treatment, and chemical reactions)
