ir-pollution control (APC) equipment
is used to prevent pollutants from
being released into the atmosphere
and is required for regulatory compliance.
However, there are many APC options
depending on the specific needs of an organization.
Proper maintenance and operation
of an APC system are crucial and will impact
upstream equipment efficiency, production
output and compliance. This article focuses
on providing an overview of APC systems,
explains their basic operating principles and
describes the application for each.
There are a number of factors to consider
when choosing APC equipment. The best
equipment for you must meet your exhaustemission
needs,
which depends on the
process gas to be treated. The selection of
equipment typically involves evaluation of
other factors, including initial costs, longterm
costs, maintenance and longevity. Understanding
which factors are most important to
you when meeting your APC needs can help
guide the decision-making process.
The APC equipment
best
suited
for
your site depends on the pollutants to be
mitigated. Here, those pollutants are categorized
into the following groups, which
are described in further detail throughout
the article:
* Acid gas
* Mercury and heavy metals
* Dioxins and furans
* Oxides of nitrogen (NOx)
* Particulate matter (PM)
* Volatile organic compounds (VOCs)
* Hazardous air pollutants (HAPs)
Acid-gas control (SOx, HCl, HF)
Choosing the right acid-gas control equipment
can have a significant impact on operation
cost and is crucial to a plant's operating
efficiency. Acid-gas control equipment
can target a number of pollutants, including
sulfur oxides (SOx), hydrochloric acid (HCl),
and hydrofluoric acid (HF). The best equipFIGURE
