Gas scrubber are designed to remove contaminants that dissolve in natural gas. Contaminants is contains dirt, condensates, oil and moisture which ensure high degree of purify Natural Gas at Filter Outlet with max flow rate 7640 m3/h at 7 bar.
There are two stages filtration process inside gas scrubber, multycyclone element process and coalesing process which can particulate removal down to 0.01 micron with efficiency 99.97%.
Multicyclone elements are designed to separate solid and liquid contaminants from gas and have the following advantages :
From flow rate 7640 m3/hr @ 7 bar, the multi cyclone process with 50 ppm contains of condensate can removed 382 kg condensate per hour. Installation of cyclone tubes is fixed between two tube sheets. Gas will enters the cyclone section and then enters each cyclone tube, where fast spinning and result from this centrifugal action moves the liquid droplets and/or solid particles to the bottom of the vessel, and the cleansed gas will streamed to other section of gas scrubber.
Coalescer are designed for treatment of liquid and gaseous medias and separation of solid and liquid contaminants from the process stream. Separation of liquid contaminants in coalescer is affected due to the ability of filter element to coalesce liquid aerosol particles of fine diameter into larger droplets (0,3 – 0,6 micron) and to drain these droplets into the sump system. There are 3 types best choices of coalescing cartridge element from Parker Hanafin, 6CU, 6QU and 7CVP, each type have different efficiency and media types (see on attachment).
Coalescing cartridges are worked out for liquid and gaseous media processing, where fine treatment is required. Coalescing cartridges will capture particles contaminations from gas and accumulated on filtration material surface. Superfine mist of lubes or moisture, contained in gas, is captured due to movement of the stream around the structural of pore layer. As filtered flow goes thru several layers of filtration material with further increase of pore diameter, mist particles reach droplet size and move inside the layer from inside down under gravitation force. As particles quantity increase, gas permeability of filtration media goes down, thus filter cartridges have to be replaced.
