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