Vapor
Phase Carbon Adsorption Systems are
designed to remove certain gaseous contaminants, including Dioxins/
Furans, Hydrogen Sulphide, Hydrogen Chloride, Ammonia and Mercaptans.
Branch
Environmental Corp.
offers a Deep-Bed design that may be used as part of a new pollution
control train or system, or as a retro-fit unit to be added to an existing
system.
The
construction of the shell and internal supports of the Deep-Bed Vapor Phase Carbon Adsorption System
are fabricated of corrosion resistant fiberglass.
Access man-ways are provided for each bed of activated carbon, for
routine inspection and replacement. Lifting
lugs and hold-down lugs are provided. |
The
process air stream,
at a temperature of approximately 140ْ
F (60ْ C),
enters the Deep-Bed Vapor Phase Carbon Adsorption System between two
horizontal beds of selected activated carbon.
The air stream separates, flowing through the upper and lower beds
of activated carbon, where the contaminants are removed, prior to the air
being discharged from the system.
Typical
removal efficiencies
are as follows:
| Contaminant |

| Ammonia |
99% |
| Mercaptans |

Numerous
types of activated carbon are
available, including pelletized, granular, powdered, impregnated, virgin
and reactivated, made out of several different materials such as coal,
coconut shell and wood. Experience
determines the optimum selection of activated carbon for each specific
application.
Benefits
of the Deep-Bed design include:
- Can
be added to an existing pollution control system as a final stage for
removal of certain contaminants.
- Made
of corrosion resistant fiberglass material for long service.
- Compact
modular design for easy and economical installation.
- Various
types of activated carbon available for different applications.
