Manufactured by:Pyro Green-Gas (formerly known as AirScience Technologies Inc.) based inMontreal, QUEBEC (CANADA)
Iron based desulfurization media has low cost and high desulfurization capacity as its main advantage, however the chemical reaction occurring during the capture of hydrogen sulfide tends to agglomerate the media pellets in larger chunks which render the spent media removal a time consuming chore. For this reason the tendency for landfill gas and biogas desulfurization has been to use activated ...

From the outside a VSA unit is very similar to an activated carbon system (several towers in parallel with an inlet manifold and an outlet manifold, each with motorized isolation valves. The difference resides in the type of adsorbent media (activated carbon for one, molecular sieve for the other) and the fact that a VSA system has a vacuum system connection at each ...

This is the most effective siloxanes and VOCs removal system. It combines the removal efficiency of the activated carbon technology with the low operating cost of the VSA system. TSA can treat high loads of siloxanes and VOCs and its thermal desorption process assures that the adsorbent will have an extended usable ...

Amine scrubbing or amine gas treating, also known as gas sweetening or acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gases. AirScience amine scrubbing process includes absorber and regenerator towers as well as accessory equipment such as pumps, heat exchangers, reboiler, ...

THE SULFOX REG PROCESS for 0,5 to 3.0 g/Nm³ Concentrations: The SulfoxREG is a gas desulfurization process that convert sulfur in raw gas to concentrated sulfuric acid. The SulfoxREG process is designed for treatment of gas having H2S and CS2 concentrations from 0,5 to 3.0 g/Nm³ (in total). Using a highly efficient regenerative catalytic oxidizer system the plant can be operated without ...

AirScience supplied its first RTO in 1993 on a paper coating operation, in those days a typical RTO had three heat recovery canisters and was using poppet type valves, 25 years later, the technology has evolved, the norm is a two heat recovery canisters and the unit use a single four way valve for cycling from the lead canister to lag role. The destruction efficiency of organics, the pressure ...

In AirScience's Bioscrubbers, the polluting compounds are first absorbed or dissolved in a water scrubber. The resulting liquid solution is then transferred to a bioreactor where microorganisms degrade the dissolved organic compounds in an anaerobic condition. The resulting bio-gas consists primarily of methane, which can be used as process fuel. Capture efficiencies are in excess of 95%. ...

Our Nitrogen Generators operate on Pressure Swing Adsorption, known as PSA Technology. PSA Technology is based on the selective adsorption phenomena of gas molecules under pressure on the surface of highly porous and efficient adsorbent, In the case of Nitrogen Generation the Adsorbent is Carbon-based Molecular Sieve(CMS). When compressed air is used for nitrogen generation, the adsorption towers ...

The DSC process is based on the property of iron sponge to convert to iron pyrite in the presence of hydrogen sulfide. To enhance the reactivity of the active product as well as the activity of the whole pellets and not only the external surface, the active media is enhanced by certain additives defined as ...

This process is primarily used for the dehumidification of biogas destined to the production of compressed natural gas (CNG) whether for transportation CNG or pipeline CNG. The process is very similar to the VSA process with the exception that the feed gas is under pressure and that the desorption sequence is designed to minimize the loss of methane as well as the energy usage (loss of ...

The system consists of a minimum of two towers, each having a bed of activated carbon. The gas travels through the carbon bed from bottom to top. Pressure drop through the bed and outlet concentrations are monitored to alert to a change in performance signaling the need to replace the carbon. To replace the carbon, the tower must be put off-stream, the full flow passing through the remaining ...
