Free Water Knockouts

Indirect Line Heaters


The free water knockout is a low cost solution for separating water in the well stream from the oil. By providing a low pressure flow and a large oil/water mixing area the majority of free water is able to separate out.

These are primarily used where large volumes of water are present. Use of a free water knockout will often allow the use of a smaller treating vessel than would otherwise be used. They can also be used where atmospheric pressure is required to dump water present in the wellhead.

There are many options on sizes and ratings for Free Water Knock Outs. Please do not hesitate to contact Accurate with any FWKO needs you may have.
