Downflow Gas Contactor (DGC)

Gas-liquid contactor-reactor. This reactor can be used for gas absorption, effluent treatment, and chemical reactions in processes involving catalysts (oxidation hydrogenation, carbonylation, and hydroformylation). Conventional gas-liquid contacting devices have lower efficiency due to low gas hold-ups, back-mixing, and less safety. This new design is simple, compact, and flexible, requiring less power and a smaller operating volume. It is also scalable without losing efficiency. Reaction rates are controllable, and the lack of moving parts ensures safer working conditions.
