Recovering Energy From Ventilation and Process Airstreams
Abstract
The high cost of energy has prompted
industry to look for new ways to reduce
operating expenses. Often ignored are the
large amounts of recoverable energy present
in the ventilation and process airstreams
discharged from the plant. The recovery
methods available range from fairly simple,
well-known devices that have been around for
years to new sophisticated equipment that is
constantly entering the marketplace.
Commonly applied to plant ventilation
and process airstreams are these three
general energy-recovery methods:
1. Substituting source-capture hoods
and high-efficiency air cleaners for
exhaust ventilation systems to permit
recirculation.
2. Placing heat exchangers in process
stacks and general ventilation airstreams,
and
3. Collecting hydrocarbon contaminants
from process stacks and reusing or
selling them.
In this paper I will touch on condensation
and electrostatic precipitation as
methods that can be used to collect and reuse
in some form, hydrocarbons from process
stacks.
