Wet Gas Compression & System Performance

Wet Gas Compression & System Performance

HOW CAN WE HELP YOU?

Because compressors are designed for gaseous fluids, the presence of a small amount of liquid can have significant effects on compressor performance. In the oil and gas industry, compression of natural gas containing both gaseous and liquid hydrocarbons during upstream production can require as much as twice the power as gas-only compression. In the power generation industry, wet gas compression, termed fogging overspray, routinely occurs when water is injected into the compressor to improve gas turbine output at reduced cycle efficiency.

Our Compressor and Turbine Performance Lab is leveraging expertise in the areas of fluid dynamics, thermodynamics and rotating machinery to study wet gas compression.

A large-scale wet gas flow loop at SwRI is used to measure compressor and loop operation for wet gas flow.
SwRI is investing in methods beyond conventional computational fluid dynamics (CFD) to improve prediction capability of wet gas compression.
