This is the easiest and most basic form of VOC control, wherein a particular grade of Carbon is chosen based on tests on the streams and on experience. The VOC`s are then passed through the Carbon bed to adsorb them and to ensure that the vapours coming out are harmless to the atmosphere. This is carried out in Carbon canisters or Tanks, depending on the flow and the site conditions. Basically, a Fixed Bed or a Fluidised Bed option is possible.

Heat recovery systems may be added in the field or included with the purchase order when originally ordered. Nacah Tech systems are designed with the optimum operating costs in mind and target the customer’s objectives. If minimizing fuel costs is the priority, an offgas preheater or combustion air preheater is incorporated. If capturing the heat that would otherwise exit up the stack via another method such as producing steam, hot water, or hot oil (as shown in photos), that heat recovery method is included. Sometimes, these methods are combined in the system to increase the heat recovered and increase the plant’s sustainability and lessen its carbon footprint. RTOs use ceramic media to preheat the incoming offgas, recuperative thermal oxidizers regularly use gas to gas heat exchangers for preheating, and those applications with high heat release or dirtier gas may require different options like the boiler or oil heater.
