VAPOR-PAC - Model 10 -VOC Control Equipment

The VAPOR-PAC Roll-Off Service units use a transportable adsorber that contains granular activated carbon and can treat contaminated air. When the activated carbon`s capacity to remove VOCs has been reached, the on-stream adsorber is removed and replaced with one containing fresh carbon. Use of the VAPOR-PAC Roll-Off Service units minimizes capital expenditure because the only site facilities typically required are ductwork and a fan. Calgon Carbon provides the entire service for the adsorption process which includes spent carbon removal, transport, and reactivation or disposal. The VAPOR-PAC Roll-Off adsorbers are owned by Calgon Carbon, and the company maintains the units in operable condition.* VAPOR-PAC Roll-Off Service units are ideally suited to remove low concentrations of VOCs from applications such as industrial plant emissions, soil remediation vents, and air stripper off-gases. The VAPOR-PAC Roll-Off Service units are offered in two sizes to cover a wide range of flow requirements. The VAPOR-PAC 5 contains approximately 6,000 lbs of activated carbon and can treat up to 5,000 cfm. The VAPOR-PAC 10 contains approximately 12,500 lbs of activated carbon and can treat up to 10,000 cfm. In order to handle a wider range of flows and VOC concentrations efficiently, the VAPOR-PAC Roll-Off Service units can also be configured as two separate adsorber beds. Each bed contains half the total amount of activated carbon. Depending on the flow and VOC concentration, the beds can be used one at a time, operated in parallel, or in series. A three-foot deep carbon bed is provided in the VAPOR-PAC Roll-Off Service unit for effective removal of VOCs, even during periods of peak concentrations.

To determine carbon life in the VAPOR-PAC Roll-Off Service units, Calgon Carbon recommends monitoring the performance via the provided sample ports. Frequency of unit exchange will depend on the types and concentrations of VOCs being treated. Exchange should be scheduled before carbon breakthrough occurs. If the beds are used sequentially, the timing of the breakthrough from the second bed can be estimated by comparing it with the breakthrough time for the first bed (assuming that they operate under similar conditions).

When an exchange is required, Calgon Carbon delivers a replacement unit. Upon delivery of the replacement, the unit containing the spent carbon is removed from the process and the replacement unit is placed on-line to continue treatment. In many cases, the delivery trailer can manage both the setting of the new unit and pickup of the old, eliminating the need for a crane. The unit removed from the process is returned to Calgon Carbon`s facility where it is emptied, inspected, refilled, and stored for the next exchange. Your Calgon Carbon Sales Representative can help evaluate the suitability of the VAPOR-PAC Roll-Off Service to satisfy your air treatment requirements. If required, evaluation studies to determine applicability and economics can be arranged. Calgon Carbon offers a wide range of adsorption equipment and activated carbon including permanent installations or smaller service equipment.
