摘要： An apparatus and method for the monitoring and abatement of fugitive VOC emissions is disclosed. Suction, generated by a fume pump (38) or a venturi type ejector (60), pulls air and VOC's from one or more sources of VOC emissions such as the mechanical seals of pumps (10) and compressors. These VOC fumes are collected, separated from any liquids in a knock-out pot (30), and directed to a flameless combustor/thermal oxidizer (50) comprizing a tube (70) packed with heat resistant material (72) and surrounded by an electric heater (74) and thermal insulation (78). This matrix bed (68) of heat resistant materials is heated to a temperature sufficient to oxidize/destroy the VOC emissions. Thereafter, an optional convective quench section (82) may be used to lower the temperature of the exhaust gases prior to their releases to the atmosphere. By monitoring the temperature and/or the amount of power needed, changes in VOC emissions can be detected.

摘要： Methods and apparatus are provided for destruction of volatile organic compounds ('VOC's') from process fumes having variable amounts of such VOC's wherein a nominal amount of the fumes are passed through an oxidizer (24) for destruction of the VOC's and the hot products from the oxidizer (24) are fed to an afterburner (30) that is principally made up of a matrix bed of heat resistant material. The heat from the oxidized gases heats the matrix bed. Fume flows exceeding the nominal flow are bypassed directly to an inlet port of the afterburner where they are passed through the matrix bed of the afterburner, which has been heated by the oxidized gases from the oxidizer (24) and are combusted into additional gaseous products in a combustion wave. The system allows for utilisation of the heat produced from the oxidation of the nominal flow for destructing fume flows that exceed the nominal flow.
