High pressure gas scrubbing has proven to be challenging. The future high pressure scrubber designs should be compact, robust and use scrubber internals that are verified at real flow conditions.

Internals used in high pressure gas scrubbing are often verified at low pressure with model fluids or air water test set ups. This will discuss why air water test setups and low pressure testing using model fluids are not appropriate for internals operating at high pressure. It will emphasize the importance of doing tests in real fluid systems at high pressure and which physical effects will affect the separation performance at high pressure.

The paper will discuss the use of CFD for designing high pressure internals for gas scrubbing; the possibilities and limitations of using CFD in the design of gas scrubbers.
