Regenerative thermal oxidizers A series of beds made from heat-resistant material which alternately store heat from the combustion chamber exhaust gases and release heat into the cooler gases entering the combustion chamber.

A schematic of a rotary concentrator is shown in Fig. 9. The wheel rotates slowly (1-3 rotations per hour) with about 90% of its face exposed to the incoming air stream. The remainder of the face is in a regeneration sector where a counterflow of hot air desorbs the VOCs for subsequent incineration. The rotary adsorber increases the VOC concentration by a factor of 100, so there is little need for supplemental fuel in the small oxidizer that can be used to destroy the VOCs. This technology has been used for the removal of styrene emissions in the plastics molding industry. The process is also used with automotive paint booths where modular rotary concentrators and a regenerative thermal oxidizer are used to capture and destroy VOCs.

A comparison of variable operation costs for a devolatilisation extruder versus purge air treatment through a regenerative thermal oxidation unit is given in Table 12.8 below. The calculation is based on an electricity price of EUR 0.05/kWh and a fuel price of EUR... 

The cost comparison, based on variable operational costs for an LDPE homopolymer train, shows that devolatilisation extrusion and purge air treatment through regenerative thermal oxidation lead to similar operational costs.
