The CleanFlow Biogas Filter is a ductile cast iron gas filter with flat cover and flanged connections. The filter holds a unique rectangular shaped filter cartridge. Unmatched large filter surface area per filter cartridge size compared to conventional cylindrical cartridges. The cartridge has its own integrated o-ring seal.
Advantages:
- Interchangeable with conventional cylindrical filters due to identical installation length
- Multi purpose. The coalescing function can easily be exchanged into dry filtration by using another type of filter
- cartridge and blocking of the liquid drain

- Extremely efficient downstream a compressor or gas engine
- Easy maintenance
- Low cost
- Light weight ductile cast-iron – aluminium

Tilt mechanisme.
The media vessel is equipped with hinges and a tilt mechanism in the frame so it can be tilted during filter media exchange. As a result the exchange of the media is very easy and safety is guaranteed.The top lid can be opened after tilting the filter vessel. The media will flow easily from the vessel to a waste container or big bag. Personnel no longer need to enter the vessel and the danger of suffocation or poisoning by remaining gases is eliminated.

H2S and Sulphur adsorption media
BIO Fe Adsorption media is granular clay based media impregnated with a ferric hydroxide medium. The adsorption media removes H2S and Sulphur compounds from air and gas streams. Other components of energetic value such as Methane will pass through the media and can be easily used as fuel.
This product is particularly efficient in the Biogas energy recovery process.
It has a high H2S removal capacity in anaerobic conditions.
Working temperature range 25 to 90ºC

H2S is stripped from the gas stream according to the following chemical reactions. The ferric hydroxide coating on BIO Fe reacts with H2S:- 2Fe(OH)3 + H2S » 2Fe(OH)2 + 2H2O + 1/8 S8
- 2Fe(OH)2 + 2H2S » 2FeS + 4H2O
This reaction results in the creation of ferrous sulphide, which turns the media black.
Regeneration Operation: BIO Fe can be easily regenerated. The Ferrous Sulphide can be converted back to Ferric Hydroxide by blowing air through the media filter.
2FeS + 3/202 + 3H2O » 2Fe(OH)3 + 1/4S8
Oxygen converts the FeS (Ferrous Sulphide) to ferric hydroxide and elemental sulphur that remains trapped in the media.
There is a visual colour indicator to show when the media is returning from Black (saturated media) to its original light Brown colour with small sulphur particles attached.
10 to 19 Regeneration Operations are possible, a minimum adsorption capacity of 400 mg H2S per gram of BIO Fe media. Each regeneration operation will absorb 40mg of H2S per gram of media. If Oxygen is present in small quantities in the Biogas, there is constant regeneration of the media through the Oxygen in the air flow.
Biogas Power Production Operational Cost
The Operational Costs to produce Electricity can be much higher if there is no Corrosion Control in Biogas recovery process. Biogas contains H2S that must be removed as much as possible before reaching the gas processing equipment. H2S causes severe problems with the gas processing equipment as the equipment is extremely sensitive to hydrogen sulphide. If H2S is removed, we can improve equipment efficiency by reducing maintenance, reventing downtime, and enhancing energy production. The hydrogen sulphide issue is a critical factor for technologies that use the biogas. If the H2S levels are too high, damage to gas treatment equipment is severe and costly.
Active Sulphur Compounds rapidly attack copper, silver, aluminium and iron alloys. The presence of moisture and small amounts of inorganic chlorine compounds greatly accelerates sulphide corrosion. Active Sulphurs ranks with inorganic chlorides as the predominant cause of atmospheric corrosion in the process industries. STANDARD ISA-S71.04-1985

Multiple stage coalescing pipeline filter separator
CleanFlow introduces a new coalescing multiple stage pipeline filter for the removal of solids and fluids from natural gas. Our unique CPF series filter separator combines 3 separation techniques in one compact filter housing. Integrated fluid slug catcher, gravitational settlement and coalescence filtration.

A unique advantage of the innovative filter design is the integrated slug catcher. Instead of the usual 2 separate units for slug catcher and filter separator only one piece of equipment is required. This new CPM series filter is a horizontal pipeline filter with extended surface area vertical elements. Element service life has been extended tenfold and more. Complete service can be accomplished with a single 3/4” adjustable wrench in a very short time.Our CPF series of filters remove solid particles and fluids out of natural gas and other types of gas, vastly reducing or eliminating service to engines, turbines compressors, valves, meters and other components. Superior filtration is achieved first through inertial impaction, secondly through gravitational settling, and thirdly through a nearly vertical coalescing multi-stage filter element with efficiencies down to 0.03 micron or higher micron rating if required.
Filter separator properties:
- Connection size : 6″ – 24″
- Flow rates (max) : 13.600 – 900.000 Nm³/hr
- Design pressure : 12 -200 bar
Advantages:
- Horizontal design with vertical filter elements. Compact construction
- Proven to provide the best coalescencing and filtration result
- Integrated slug catcher
- Quick opening and closing
- Fast and easy maintenance with short down time
Filter element properties:
- Designed as standard for 1 bar (15 psi) differential pressure
- Particulate removal efficiency of 99.25% of 0.1 micron, 99.99% > 0.7 micron

What is coalescing?
Coalescing is separation of fluid aerosols and droplets from a gas. Wet gas flows from the inside to the outside through a coalescing filter cartridge which is installed in a filter housing. The inner filter layer is made of a highly efficient coalescing media and the outer layer is a coarser drainage layer.
The fine fibres of the inner layer catches the fine fluid aerosols and droplets. Next they go through the depth of the filter cartridge to form bigger droplets on the fibres of the filter media. When the droplets reach the outside surface of the cartridge they fall in the sump compartment from which it is drained. Coalescing filter cartridges will remover particles with the same efficiency as solids filter cartridges with the same grade.
