Manufactured by:Pyro Green-Gas (formerly known as AirScience Technologies Inc.) based inMontreal, QUEBEC (CANADA)
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 ...

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, ...

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 ...

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 ...
Manufactured by:Pyro Green-Gas (formerly known as AirScience Technologies Inc.) based inMontreal, QUEBEC (CANADA)
This process is used at high pressure for the drying of gas from the discharge of carbon dioxide removal system, to very low dew point prior to the liquefaction of natural gas. The duty of the PSA in this application is to remove all humidity from a gas saturated with humidity as it exits the amine scrubbing system (CO2 removal ...
Manufactured by:Pyro Green-Gas (formerly known as AirScience Technologies Inc.) based inMontreal, QUEBEC (CANADA)
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 ...

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 ...

The Non-Thermal Plasma Multi-Pollutant Control process developed by AirScience, Saskpower and CANMET has demonstrated at the laboratory that SOx, NOx and mercury can be removed from coal-fired flue gases at a fraction of the capital and operating cost of conventional control technologies. The Radical Shower approached used in this proprietary process has shown advantages over the Electron Beam ...

Steam reforming of hydrocarbons is conventionally used for feedstock production for methanol synthesis, hydrogen production, ammonia synthesis and Fisher-Tropsch synthesis. Syn-Gas or Hydrogen can be produced using the Steam Methane Reforming ...
Manufactured by:Pyro Green-Gas (formerly known as AirScience Technologies Inc.) based inMontreal, QUEBEC (CANADA)
The process consist in cooling the biogas to a temperature lower, by a few degrees, than the desired dew point temperature, to condense the humidity along with desolved compounds such as hydrogen sulfide and siloxanes as well as low boiler hydrocarbons. The gas is then re-heated to the desired temperature through a compression stage ...

Hydrogen production through Steam Methanol Reforming (SMR). The methanol feedstock is mixed with water in specified ratio and pressurized. This mixture is passed through evaporator, metering pump and super heater. The hot gas mixture is then fed into a catalytic reactor. The reaction of methanol reforming and the shift reaction, takes place in the catalytic reactor of fixed beds simultaneously to ...
