Treatment of gas by liquid absorption is a common unit operation in industry. Traditionally, contact between the gas and liquid is accomplished in co-current flow utilizing a tower or column. With the increased demand for natural gas and renewable gas, higher treating capacities for new installations and methods for de-bottlenecking existing plants are needed. Co-current gas treating with static mixers is an increasingly attractive alternative for process intensification. The corrugated plate (SMV-style) mixer is currently the most widely used mixing element for gas-continuous mixing with a liquid phase and has been recommended as the best standard option for this service. These geometries are also used as structured packing for counter-current service. Unfortunately, the pressure loss correlations available to the design engineer are sparse and only valid up to Re_G<50,000. In contrast, most gas pipelines operate in the range of 10^5
