This helical-coil process is effective at purifying natural gas
Mueller Environmental Designs
The KLS helical-coil natural-gas separation technology (photo) utilizes impingement, coalescence and inertia to remove 99.9% of solids and 99.5% of liquids (0.3 μm and larger) without the maintenance and expense of replaceable filter systems. KLS is typically employed to remove black powder, iron sulfides and oxides, lube oil, glycol, salts and condensates from natural-gas streams. The patented helical coil of the process forces contaminants to impinge on the housing wall, creating a film that falls downward into a contaminant sump. The clean-gas outlet-tube’s position directs the flow inward toward the center axis, and away from contaminants, preventing re-entrainment. Unlike cyclonic processes, the KLS process is not velocity-dependent, so turndown is not a concern. — Mueller Environmental Designs, Inc., Brookshire, Tex.
