ATLAS FREE WATER KNOCKOUTS

ATLAS Free Water Knockouts are designed to reduce the load on the treating process by removing large volumes of free water prior to treating of the oil to remove emulsified water. This leads to reduced treating costs and typically a smaller treater.

ATLAS Free Water Knockouts are available in two designs; a fully flooded 2 phase design which separates oil/gas from free water and a 3 phase design which separates oil, gas and free water.

ATLAS Free Water Knockouts are standard as unfired, however a fired option is available.
