Knock-Out DrumVane Mist ExtractorKO-V01KO-C01Models - Production RangeVM-V01VM-D01Operating PrincipleThe extractor consists of a vanes pack formed by a series of parallel platescomplete with an intermediate series of hooks. The gas, flowing through thevanes, is forced to change direction several times and the heavier liquiddroplets are then smashed against the wetted walls. The small particles arecoalesced by agitation and surface contact. The agglomerated liquid is thendrained perpendicular to the gas flow into the sump.EfficiencyThe efficiency of this kind of filter isa typical function of particle size anddistribution, particle loading, elementface velocity and pressure drop. Thevane mist extractor is able to removeliquid droplets up to 8 microns andlarger.Cross section KO-DrumTECNOFORGE Systems reserves the right to change design, specification and materials without notice4

CYC-M-DApplicationsThe cyclone separator is used in a wide range ofapplications in the natural gas and chemical processindustries such as:● Metering and reducing Stations: removing liquidhydrocarbons, water and sand● Natural Gas field application● Gas and Fuel transmission lines● Meter Installations● Gas compressorsOperating principleThe operating principle of the cyclone filterseparator is based on the action of centrifugal forcesthat separate the solid and liquid parts. The gas,entering into the cyclone, forces the particlesagainst the cyclone walls moving the liquid dropletsand the solid particles to the outer periphery of thetube and then dropping them into the collectionchamber at the bottom of the vessel. The cleaned gasexits instead to the top of the vessel to theeventual second stage cartridge dry separator toremove the finest solid particles. The cyclone filterseparator could be designed with a single cycloneaction or with a multiple cyclones action in order toraise the efficiency of the process.Cross section Multicyclones Filter5TECNOFORGE Systems reserves the right to change design, specification and materials without notice

Dual-stage FiltersOperating principleThe absolute filter separator is designed to beinstalled in a vertical or in a horizontal configuration,it could be inserted a "quick opening" end closure foraccess to the filter elements. The gas enters the vesseland encounters a labyrinth of pipes that give acentrifugal motion to the particles of 10 micron andabove to the bottom of the filter. Smaller particleswhich exhibit significant brownian movement collidewith each other coalescing to a single droplet.Anelastic collision of solids produce then aggregateswhich subsequently are swept by the liquid into thesump. Particles that remain suspended encounter thefilter coalescer elements and then they collide withand adhere to the fibers or other droplets andcoalesce. This agglomerated liquid is then forcedthrough the media by the drag of the gas for thesecond stage separation. The second stage section,which is the vane mist separator, by changing thedirection of the vapour to generate an increase inapparent density of the liquid phase, trap all the liquiddroplets in the hooks draining the same into the sump.Filtering CartridgeThe filtering elements are engineered, designed andmanufactured, in a variety of medias, to provide thereliability and consistency in performance. This isnecessary for the delivery of outstanding operatingefficiency in a wide variety of filtration applications.Our experienced Sales and Application Engineers canassist you in selecting the correct element to solveyour particular filtration problem.Production RangeVertical Type Mod. ABS-VHorizontal Type Mod. ABS-HApplicationsThe absolute filter separator is a multi stageseparator used in a variety of applications in thenatural gas and chemical process industries such as:● Metering and reduction Stations: removing liquidhydrocarbons, water, sand and pipe scale.● Ahead of gas storage fields to prevent the injectionor withdrawal of solids and liquids.● On the suction side of the compressor to preventwear from solids and liquids entrained in the gasstream.● On a gas processing plants to remove solid andfree liquids in order to prevent fouling of processequipment and poisoning of catalyst beds.● Downstream of amine, glycol, potassium, carbonatesulfinol and absorption oil contactors to recoversolutions and reduce solution losses.EfficiencyThe efficiency of this kind of filter is a typical functionof particle size and distribution, particle loading, elementface velocity and pressure drop. A typical performanceefficiency is 100% for solid particles of 3microns and larger and 99% for particles between0.5-3 micron and 100% for liquid particles of 3microns and larger.TECNOFORGE Systems reserves the right to change design, specification and materials without notice6

Why an indirect HeaterIt is to be found in an economic justification. Thefluid carrying coils are operated at a maximumpressure of 3,000 psi. (depending on the customerrequirements), whereas the shell of the indirectheater containing the heat transfer medium (water)is operated usually at atmospheric pressure, or at avery little pressure above it, therefore it’s required athin wall vessel for the heater shell. In addition, alsothe firetube needs withstand only the atmosphericpressure plus a few pounds. It would be prohibitivefrom several standpoints to attempt to makefiretube to withstand the pressure of 3,000 psi aswell as the heater shell itself; thus the creation of theindirect type heater with fluid carrying high pressurecoils immersed in an atmospheric pressure waterbath heated by a firetube operating close to theatmospheric pressure.Gas HeaterWhat is an indirect HeaterAn indirect heater is an oilfield terminology for avessel complete with: a firetube (which is usuallyfired by natural gas), a fluid around the firetube(which is usually water) and, immersed in the fluid,a coil containing the fluid to be heated. The waterbath around the firetube is heated directly by havingcontact with the firetube and the coil containing thefluid to be heated is immersed in this hot water bath.Because there is an intermediate step of heattransfer between firetube and coil, the heater derivesits oilfield terminology of “indirect heater”.Use of the indirect HeaterNormally the natural gas is produced at highpressures ranging from 1,500 psi up to 3,000 psiand it’s usually transferred to sale gas lines thatoperate at 1,200 psi and below. The indirect heateris often employed to supply heat to a gas streamthat is being expanded from some elevated pressure(well head) to some intermediate pressure(intermediate production equipment) or to theactual sale line pressure. Heat supplied is used tocompensate for the Joule-Thompson effect of the gasthrough expansion.TECNOFORGE Systems reserves the right to change design, specification and materials without notice8

A most frequent applicationThe high pressure fluid is introduced to the heatingunit through a choke located at the heater inlet, andthe expansion takes place immediately inside theheater in the water bath. Then, as the fluid passesthrough the steel coils, it’s raised to the desiredoutlet temperature suitable to compensate theJoule-Thompson effect during the expansion. Thesteel coil, which is subject to the well head operatingpressure, is subject further to corrosion by the fluidcarried within the steel pipe as well as erosioncaused by the high velocity of the fluid itself. In timethe combination of corrosion and erosion takes itstoll in wall thickness of steel pipe.Features AvailableRemovable FiretubeRemovable Tube bundleLarge firetube combustion volume per square footof firetube areaQuality fabricationX-ray and stress relieving facilitiesAutomatic control, regulation and safety systemssuitable to operate also without electric power.High Performance and High EfficiencyDesigned and manufactured inaccordance to:API 12 KASME VIII9TECNOFORGE Systems reserves the right to change design, specification and materials without notice
