A workhorse of the gas industry, the Gas Filter Separator is one of the most widely used filtration devices on the market. Introduced more than 70 years ago, it has become the equipment of choice to purify natural gas and protect your capital investment.
HOW IT WORKS
Often confused with a Reverse Flow Coalescer or a Separator, its design consists of three stages of filtration
and separation: the knockout stage, the element stage and the separator stage. The element and separation
stages are housed in separate compartments.
Knockout Stage
As natural gas enters the Filter Separator, it impinges on element support posts, also known as risers. Correct
length of the risers is important to prevent direct gas impingement on the elements. Gas impingement on
the risers is used to disengage any contaminant from the gas stream via impaction, deflection and gravity. In
order to maximize deflection and make the most of gravity separation, Jonell Systems Filter Separators utilize
HORIZONTAL FILTER SEPARATOR
A Horizontal Filter Separator is fitted with two separate liquid collection chambers separated with a baffle
plate. Each liquid chamber is sized proportionally to the upper barrel as well as expected liquid loading. Two
stages of controls (manual or automated) are required for liquid monitoring and drainage.
Vertical Filter Separator
A Vertical Filter Separator is designed with a top-
to-bottom flow configuration and is most commonly
designed with a vane pack or mesh-vane separator
stage. This design also necessitates two liquid
collection chambers. Any liquid drained from the first
stage, or upper chamber, is collected and drained
off to a common drain header. The second stage,
or lower chamber, retains liquids that have been
removed from the gas stream by the vane pack and
is drained to a common header.
