Zeolite VOC Rotary ConcentratorAre you looking to reduce your operating costs? Do
you have a high volume airflow to treat from your industrial process?
Because a rotary concentrator can reduce the air flow volume by as much as a 15:1 ratio, the final oxidation treatment (RTO) required is much smaller, therefore, greatly reducing ongoing operating costs. Which processes are suitable for a rotary concentrator? Adsorption takes place at low temperature, typically close to ambient, and desorption at elevated temperatures between 360 and 420º F.
The boiling point of the VOC should be above ambient temperature, and in practical terms, less than around 400º F. If higher, the concentrations must be very small. The VOC concentration in the inlet stream should be from 0 to around 1.5 gram per cubic meter air (0-3% LEL). The lower the inlet concentration, the higher the concentration factor can be. At the low end, 15:1 is feasible and at the high end about 5:1. Above the 15:1 concentration factor, there is too little energy in the desorption stream.

How
is this possible? The zeolite rotary concentrator uses temperature swing
adsorption to remove VOC from the high volume air flow. The concentrator
delivers the VOC to a smaller or ‘concentrated’ process stream,
which in turn is fed into the final oxidation treatment solution (typically
an oxidizer). 
Because
rotary concentrators use adsorption, to be suitable for this operation,
the process releasing the VOC into the air should operate at close to
ambient temperatures or somewhat higher. The air stream should be generally
less than about 100º F, although some applications run at 120º F without
cooling.
