PRODUCT BULLETIN
VAPOR-PAC® ROLL-OFF SERVICE
Equipment for VOC Control
Description
The increasing emphasis on cleaner air presents the industry with new
challenges to control and reduce toxic volatile organic compounds
(VOCs) at air emission sources. To help facilities comply with current
and future VOC regulations, Calgon Carbon offers VAPOR-PAC Roll-Off
Service units, which use adsorption on granular activated carbon to
remove VOCs from high volume air emissions. The service also
minimizes capital expenditures and eliminates on-site spent carbon
transfer and regeneration.
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
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.*
Features / Benefits
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.
VAPOR-PAC 10 Pressure Drop
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.
• Eliminates on-site carbon handling
• Minimizes spent carbon disposal concerns
• No major capital investment required
• Wide variety of activated carbons
• No on-site equipment required for loading or offloading
*Damage to VAPOR-PAC Roll-Off Service units caused by negligence or
misapplication is the responsibility of the user.
Example using 12,000 lbs AP4-60, 60°F. Other carbon products
will produce different curves. Please contact a Calgon Carbon
representative for additional, information. ,

Pressure Loss (inches w. c.)
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.

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

Safety Message
Wet activated carbon preferentially removes oxygen from air. In closed
or partially closed containers and vessels, oxygen depletion may reach
hazardous levels. If workers are to enter a vessel containing carbon,
appropriate sampling and work procedures for potentially low oxygen
spaces should be followed, including all applicable federal and state
requirements. Please refer to the MSDS for all up to date product
safety information.
