Pressure Swing Adsorption: An Energy Conservation Success Story
Abstract
Pressure swing adsorption is being successfully
used as an efficient separation process in
refining, chemical, petrochemical and gas processing industries. This separation process provides
a simple and economical alternative to
conventional means.
Gasoline vapor recovery is a good example
of a pressure swing adsorption solution to an
air pollution problem. A net income of more
than 25 million dollars each year is realized by
bulk gasoline loading terminals in the United
States which utilize pressure swing adsorption
for vapor recovery and pollution abatement.
A relatively new application of pressure
swing adsorption is found in the gas processing
industry. Raw fuel gas currently used in gas
engines for compressor drivers can be conditioned
by pressure swing adsorption to improve
fuel quality. Conditioned fuel can increase
efficiency and decrease maintenance costs.
This paper discusses the technical principles
of adsorption and how these principles are
related to energy conservation concepts. Discussions
of specific applications provide
insight into pressure swing adsorption as a
separation process and stimulates ideas for
viable new applications.
