High-Efficiency Phase Separation Internals

Enhance separation of oil, gas, sand, and water

High-efficiency phase separation

Compact and robust technology lowers cost

Our robust, high-efficiency phase separation internals are used in scrubber vessels, two- and three-phase separators, free-water knockout drums, flare knockout drums, contactor towers, and slug catchers to improve separation of oil, gas, sand, and water.

Designed to meet the most stringent demands for separation performance in a compact space, the internals

  • improve separation effectiveness at very high operating pressures
  • enable reductions in pressure vessel size and weight, and hence, required floor space
  • decrease operational risk
  • protect the downstream process system from contamination
  • reduce the need for chemicals such as defoamers and demulsifiers
  • maintain high separation efficiency under turndown conditions.

By helping to capture the free liquid in the gas stream, these internals minimize loss of liquid hydrocarbons or glycols. They are also valuable for retrofitting existing vessels to achieve increased capacity or better performance.

Use separation volume efficiently

Operators are continuously looking to improve efficiency and reduce overall costs. In-vessel compact separation enables more efficient use of separation volume compared with traditional gravity separation vessels. Our high-efficiency phase separation internals further enhance this efficiency by using centrifugal, capillary, or electrostatic forces rather than just the force of gravity to decrease separation time; reducing separation distances; and employing perforated plates in separators and mesh pads in scrubbers.
