MUCH MORE THAN A FILTER OR A SEPARATOR UNIT

Until you realize what a King Tool Self-Cleaning Reverse Flow Mist Coalescer can do, you might mistake it for something less.  Like a conventional filter separator, it contains an array of coalescing filter elements.  Fibers catch and hold solid particles while merging and draining mist droplets.  But the resemblance ends there.  "Reverse Flow" means gas travels from the inside of the elements to the outside.  This hydrodynamic pattern, combined with proprietary internal features and scientific sizing based on all properties of the flowing materials, completely eliminates re-entrainment of coalesced liquid.  That includes any dissolved solids and suspended particles much smaller than one micron.  Reverse flow also allows self-cleaning backflow of selected elements without a shutdown.  And it facilitates incorporation of an efficient slug interceptor section.

EFFECTIVE SELF-CLEANING AND SLUG INTERCEPTION

A self-cleaning cycle is actuated by a hand crank or electric motor.  The motor may be started manually or by a timer or differential pressure sensor.  In less than two minutes, every filter element is momentarily connected to a backflow line leading through a regulator to suitable disposal.   Only a few elements at a time are out of service.  Filter life is typically extended by a factor of 20 to 50, often more.  This feature is more than just a perfunctory blowdown.  Numerous details have been carefully engineered--including pressure drops, patterns of liquid and gas flow, and specially designed filter elements--to dislodge and flush out virtually all solids.  The integral slug interceptor is sized to keep free liquid away from the filter elements.  Liquid drains to an appropriately sized barrel for discharge.

USE IT WHERE NOTHING ELSE CAN HANDLE THE PROBLEM

These units are custom-engineered and sized for each application to take care of the most difficult gas contaminants, such as the following:

You do not need a King Tool Self-Cleaning Reverse Flow Coalescer for every job.  But there are cases which cannot be handled by an ordinary filter separator or even more "advanced" equipment.  For instance, iron sulfide particles from sour gas pipelines break up into aerosols that penetrate the finest filters.  In a King Tool Self-Cleaning Reverse Flow Coalescer, such particles are flushed out in the liquid, with virtually zero re-entrainment.

PROVEN IN REAL-WORLD FIELD TESTS SINCE 1969

For more than 25 years, thousands of these units have been protecting critical equipment in gas pipelines, refineries, and chemical plants:

A King Tool Self-Cleaning Reverse Flow Coalescer has never failed in the service for which it was designed.  Users are happy to tell about their experiences.  Long-term field success is a more reliable witness than performance tests using inlet and outlet samples, subject to gross errors.  That success is based on proprietary design principles and data derived from laboratory and field research.   All physical properties of your liquids and solids are considered.

GREATLY REDUCE MAINTENANCE AND DOWN TIME

Periodic self-cleaning lets you keep running on the same coalescing filter elements at peak efficiency for years in typical cases.   Sudden plugging by a particle storm never results in an emergency shutdown.   Head loss remains low.  Filter replacement can always be deferred until a conveniently scheduled time.  Exclusive computer design methods and special internal features handle overloads and wet restart surges.  The custom interceptor swallows slugs that would disrupt mist elimination or even destroy filter elements.  Downstream equipment maintenance stays low.  Although a vertical configuration can be furnished for tight spots, the standard horizontal arrangement allows exceptionally convenient access.  Filter elements lie within arm's reach, and replacement is a comparatively quick and clean job for one person.

A COST-EFFECTIVE INVESTMENT OVER THE LONG TERM

With a King Tool Self-Cleaning Reverse Flow Coalescer, you know you have bought the best guaranteed protection for your equipment and your operation.   It pays for itself the first time you save the cost of overhauling a compressor or replacing a molecular sieve bed due to carryover during a sudden upset.  And it keeps paying for itself many times in avoiding shutdowns for filter replacement as well as cutting routine maintenance expenses caused by traces of liquid and solids in the gas.   King Tool keeps its own cost low and quality high with an integrated manufacturing facility that handles all work in-house--including filters and stress relieving.  Let King Tool Company engineers show you the economics and explain the technical details.
