Machines operating in multiphase flows are subject to some of the most demanding process conditions. Whether those conditions include a slurry of sand and heavy crude, a mixture of hydrocarbon gas and condensates, or any other multiphase flow, the machine’s performance and reliability are impacted greatly. These performance impacts present numerous challenges to both the machine designer and the operator.

The Machinery Program at SwRI provides a key resource to both the machine designer and the end user to ensure that process machinery performs reliably under all process conditions.
