Global Thermal Oxidiser: Global - Remedi-Cat™ - Datasheet

Application Environment

The remediation of contaminated land often releases organic vapour contaminants that are discharged from soil vapour extraction and ground water treatment systems. The resulting emissions can cause severe problems for operators, neighbouring communities and the environment.

Remediation companies are generally subject to rigorous emission control regulations that are enforced by both local authorities and the Environment Agency. Failure to limit these emissions can create a nuisance to both residential and commercial neighbours, prompting complaints that give rise to regulatory body investigation. Costly fines or an Enforcement Notice may result, forcing the site operator to take corrective action before any further work is carried out. This can result in an extensive delay to the project, perhaps triggering penalty clauses that are included in the contract.

Product Aim

The Remedi-Cat™ is designed to provide 99+% destruction efficiency of volatile organic compounds (VOC’s) generated on site, ensuring regulation compliance whilst preventing investigation, fines and project delays.

How it Works

The Remedi-Cat™ Catalytic Oxidizer efficiently destroys VOC’s, drawn by the regenerative system blower or fan from extraction wells and diluted to the appropriate concentration using a dilution air valve. The blower emits the contaminated air into the cold side of the primary heat exchanger where it is preheated prior to entering the gas burner. Once in the burner the air achieves oxidising temperature before entering the catalyst module. An exothermic reaction takes place as they pass through the catalyst. The clean, VOC free air which remains hot, passes to the next compartment of the exchanger and the energy released by the reaction is used to preheat the incoming air. The de-contaminated air is then released to the atmosphere.

The Remedi-Cat™’s low weight and small footprint ensure both ease of mobility from site to site and
ease of placement where space is premium. The integral regenerative blower does not require a separate extraction blower and is therefore compact in design. The reactor has a fully welded, leak tested stainless steel interior with high-density insulation allowing for safe, long-term operation. A flow recorder and temperature recorder provide effective system monitoring, allowing regulatory records to be easily kept.
The burners are fuelled by either natural gas or propane to provide greater flexibility. A system control panel reliably indicates the status of the burner, catalyst and safety circuits. The system will automatically and safely shut down should an error occur, the cause being identified on the liquid crystal display.
