The EPA developed the Maximum Achievable Control Technology
Standards (MACT Standards) to reduce the effects of Hazardous Air Pollutants
(HAPs) generated by industry. The standards that were developed through this
MACT approach became known as the National Emission Standards for Hazardous Air
Pollutants (NESHAPs). The purpose of these NESHAPs is to protect the public
health by reducing discharges of HAPs from major air emission sources.
Magnesia-based chemistries are employed regularly for the
treatment of acid gas emissions in both manufacturing processes and at
utilities. Effective at neutralizing acidity at the source, our products
effectively treat to MACT regulatory standards, and in addition help to
streamline the treatment process by way of in-line addition.
Environmental regulations require coal and gas-fired power
plants to sequester SOx gas particles as they form, and to continually improve
SOx gas removal processes and efficiencies. Such processes are conducted
through filter membranes and chemical scrubber processes. Caustic soda is the
most commonly-used chemical for pH control in sulfur dioxide (SO2) scrubbers, but it also tends to fluctuate in price and can be hazardous for employees to
handle. Alternatively, magnesia-based products can help to reduce chemical
usage, as well as the cost of compliance in a safer way for the environment and
Hydrochloric Acid (HCl) Treatment
The generation of acid gas by industry has necessitated
in-line treatment processes to reduce environmental impact. Our
customized products, when added to wet scrubbing systems prior to the stack,
effectively reduces emissions.
