3 Terms and definitions
For the purpose of this standard, the following terms and definitions apply.
3.1
volatile organic compounds (VOCs)
organic compound that participates in atmospheric photochemical reactions, or is defined in accordance with relevant provisions
In characterizing the overall emissions of VOCs, total volatile organic compounds (in TVOC) and non-methane total hydrocarbons (in NMHC) can be used as pollutant control items based on industry characteristics and environmental management requirements.
3.2
industrial organic waste gas
waste gas containing volatile organic compounds emitted in industrial production process
3.3
regenerative thermal oxidizer (RTO)
device that purifies industrial organic waste gas by combustion and applies heat transfer media for heat exchange and heating up of the waste gas to be treated as well as heat exchange and cooling down of the purified exhaust gas, which is usually composed of divert device, regenerative chamber, combustion chamber and control system, etc.
3.4
heat transfer media
functional materials that realize heat storage and exchange during the operation of the RTO
3.5
divert device
valve or rotary gas distributor that changes the flow direction of waste gas to be treated and purified exhaust gas
3.6
interval time
interval between changes in gas flow direction
3.7
purification efficiency
ratio of mass flow of VOCs processed by the RTO to that of VOCs entering the RTO, in %. The following equation applies:
