Regenerative thermal oxidation with composite ceramic purification plants

RTO plants: suitable for pollutant organic solvents abatement

Design · Revamping · Saving · Funding · Technologies

The regenerative-thermal plant with composite ceramic media has been widely tested for purification of effluent gases, with many installations in the USA and Europe.
Regenerative-thermal plants are usually adopted due to their highhigh purification efficiency and flexible operation which makes possible to eliminate a wide range of solvents, with the possibility of future modification of their type and quantity, without any change in the abatement plant’s efficiency.
The plant allows maximum operating safety for oxidation, minimising at the same time the fuel operating costs.

Plant Design features and components

airTReco 's regenerative-thermal plant (RTO) with composite ceramic media have been widely tested with many installations in the USA and Europe and they are one of the best existing solution in the field of abatement of volatile organic compounds (VOCs). In fact, airTReco always guarantee the high performance required for gas emissions given by Authorities pursuant the local legislation, always overcoming the periodical inspection by institutional agency.

These plants offers an high purification efficency and great flexibility, making possible the abatement of a wide range of solvents and a future implementation also, for both kind and quality of itself; without change the efficency of the plant.

The plant allows maximum operating safety for oxidation, minimising at the same time the fuel operating costs. In fact, these plants can reach the highest energy efficiency until self-supporting, thanks to the high thermal performance ceramic exchanger.

Thermal exchange

We reach a very high thermal efficiency thanks to composite ceramic media use instead of the traditional ceramic saddle. The result is that:

lower energetic consuption of process fan;
significant fuel save;
plant costs reduction;
management costs reduction.

High purification efficiency

Special and exclusive valves, designed and made by us, allows our plants to have a quite perfect sealing and a 99,9% purification efficiency. That's not just a technical virtuosity but a necessary result to guarantee the rispect of the legislations that fix limits who are sometimes unsatisfactory at 99-99,5%

Burner

The burners, run on methane, complete the preheating of the gaseous flow and automatically keep the temperature of the combustion chamber constant at the preset value

The gaseous effluent stay for a calculated time to comply with abatement of the solvent present, with outlet concentration from the purifier lower then the legal limit.

Heat exchange towers: 3-5-7

We install at least 3 to avoid solvents spikes in the stack and pressure variations during flow inversion. Each of the three recovery chambers with composite ceramic media is used cyclically, both for preheating and cooling with an efficiency up to 97% (± 2%). Thanks to preheating the fuel is limited to the minimum value.

Moreover, our plants are modular: they offer the possibility of expansion from the rated value to its double, simply adding 2 more heat exchange towers and 2 more combustion chambers.
