  • Flooring manufacturer chooses catalytic products to reduce energy usage

    HEAT RECOVERY SYSTEM A leading floor covering manufacturer contracted Catalytic Products International, Inc. to design and install a heat recovery system that uses waste heat from their Regenerative Thermal Oxidizer. The system had to be very efficient since the energy available in the RTO exhaust was fairly low temperature. The other challenge was to design a useable system that returned heat to ...

  • Case study - Catalytic products international replaces RTO with a VECTOR Catalytic Oxidizer

    A chemical processing facility recently installed a VECTOR Catalytic Oxidizer to replace a competitors Regenerative Thermal Oxidizer. The RTO was installed 5 years earlier and could not provide the reliability demanded by the client. The problem stemmed from a basic mis-application of the technology. As is very common, many air pollution control equipment manufactures have abandoned recuperative ...

  • Case study - Custom web coater chooses the VECTOR Catalytic Oxidizer

    A custom web coating facility recently installed a VECTOR-Series Catalytic Oxidizer to eliminate the VOC emissions exhausted from three different coating lines. After an extensive technology review the VECTOR Catalytic Oxidizer was installed because it offered the highest reliability, lowest installed cost, and lowest operating costs. The application called for a system that could provide ...

    A custom coating operation recently installed a TRITON-Regenerative Thermal Oxidizer manufactured by Catalytic Products International, Inc. The TRITON system was contracted on a turnkey basis in which CPI engineered and installed; the fugitive enclosure system to meet method 204, the ductwork system from all production lines, foundation work, electrical integration, and rigged the oxidizer. The ...

  • Treatment of petroleum refinery wastewater by distillation-assisted catalytic oxidation under low temperature and low pressure

    A distillation-assisted catalytic oxidation (DACO) process under low temperature (100 °C) and atmospheric pressure was investigated to treat heavily contaminated wastewater from oil refining industry. The DACO experiments were carried out in a distillation batch reactor, using CuO/γ-A12O3 as catalyst. The experimental temperature was kept at 100 °C and H2O2 oxidant was supplied into the reactive ...
