Filter Separator Introduction from shenyang wensheng

Breif Introduction

solid particles,liquid condensates and lubricating oil present in any natural or process gas pipeline provide several maintenance problems with compressors and instrumentations.liquid,especially,wet the pipe walls and tend to"glue" the solids in the line thus creating deposits which result in increased pressure drop and reduced transmission efficiency.To solve the probem,we have developed a full line of cyclone separator, filter separators,and absolute separators ,Micro-seperator,for complete removal of solids and liquid from natural or processed gas streams,cyclone separator and filter separator are single or multi-stage devices utilizing gravity,centrifugal force,intertial impaction, direct impaction and brownian diffusion to achieve an effective removal efficiency of 99.9% for filtration rating of one micron and larger .

Overwiew

Filter separator is a sturdy,combination package designed to remove contaminants from liquid-free natural gas streams.

available in single and dual boot, filter-separators containing one micron filter elements are used for the removal of dust,rust and small particles and handle gas capacitiesup to 325mm scfd at 1400psig.vessels containing 0.3micron elements are used for the removal of lube oil and other contaminants and handle gas capactities up to 221mm scfd at 1400psig. wensheng also offers expertise.to design and build customized units outside of our standard range.our filter separators are designed for high gas/low liquid flow operations and are typically employed upsteream and downstream of compressors,glycol dehydration units and fuel gas applications.

as natural gas enter the unit,filter tubes and elements in the first section capture solid particles and cause any liquids present in the stream to coalesce into larger droplets.in the secnd section, the wire mesh or vane mist extractor captures the liquid droplets. the

resulting stream in then virtually free of all particles two microns and larger

the standard unit is equipped with one or two liquid boots to collect fluids removed from the gas stream. the fluids are discharged from the vessel by means of an automatic level controller and level control valve.

Filter Elements

The cylidrical Filter elements are composed of different layers of glass fibers of specific rating,which are uniformly compressed to a proper gradient density and impregnated with inert phenolic resins and silicones. the structure of the elements is made of a thick perforated center core,to withstand flow pulsation,with a "meida migration barrier" placed between the core and the filter media. the end seals and gasket are molded onto the element to prevent the internal bypassing and to give better assurance of high efficiency in solid/liquid separation

Materials specification:

Filter Media:Molded fiberglass bonded with phenolic resin

Inner core:carbon steel or s.s

End cap:Carbon steel or s.s

Gasket:Rubber

Quick Opening Closure

quick opening closure provides a practical solution which assures safety access to the filter and allows to manage the larger size,for opening and closing,in a few minutes.

all parts are made of forged steel or by quality frame and each closure is widely tested after manufacturing to give assurance of maximum reliability through time. now we have LSM wheel paddle QOC,(patent type), bandlock QOC,Clamp QOC,screw QOC and electrodyanmic QOC  etc.
