"Air Pollution 101 A - Acid Gases, NOx and VOC Control"
Under the Clean Air Act, the U.S. EPA establishes national ambient air quality standards for six common air pollutants including carbon monoxide (CO), ground level ozone (O3), lead, nitrogen oxides (NOx), sulfur dioxide (SO2), and particulate matter (PM, PM10 and PM2.5). In parallel with this effort, the EPA, states, and local air pollution agencies have developed and set increasingly stringent emission standards to reduce the emissions of primary air pollutants NOx, SOx, PM, PM10, PM2.5, as well as VOCs and other types of acid gases.

Industry is obliged to install and operate myriad air pollution control devices, methods, and tactics to reduce air pollution. As a result, the air quality in the U.S. has improved significantly since 1980: emissions have dropped more than 50% between 1980 and the present despite the increase in gross domestic products, vehicle miles traveled, and the U.S. population.

The panel discussed the emission sources of acid gases, NOx, and VOC, the regulatory requirements, and the fundamentals of control technologies in this foundational workshop.

"Ceramic Catalyst Filter Systems for Control of Glass Furnace Emissions"
The glass industry is experiencing increased pressure from the EPA to control particulate, SO2, and NOx emissions. In today's regulatory environment, most rebuilds or furnace expansion projects will involve upgrading or adding air pollution control equipment. The challenge is particulate control with simultaneous control of NOx, SO2 HCl, and metals.

In the US, Tri-Mer has installed its catalytic ceramic filter system at three container plants, two flat glass plants, and one tableware plant. Additional projects are pending. The Tri-Mer Ceramic Catalyst Filter system is a dry filtration technology for the simultaneous collection of fine particulates, SO2, HCl, metals, and NOx. Ceramic filters have quickly become the pollution control technology of choice for glass furnace emissions. The core of the technology is a NOx catalyst impregnated within the walls of the low-density ceramic filters. Integrated dry sorbent injection of hydrated lime controls SO2 and HCl. The ceramic catalyst filter technology has been operating on glass plants in Europe since 2009; initial adopters of the technology have all ordered additional systems. The theory of operation for the UCF, along with performance data for commercial installations was presented.

"Tri-Mer Ceramic Catalyst Filter Systems for Cement NESHAP or CISWI Compliance"
The Cement NESHAP is a set of EPA rules regulating emissions of THC (Total Hydrocarbons) -- including specified Organic HAPS-- and particulate matter (PM).  Advances in technology allow simultaneous control of both pollutants using fibrous ceramic filter elements with catalyst embedded in the filter walls.

Catalytic ceramic filter systems destroy the Organic HAPS and are a practical approach for many sites to meet THC/O-HAPS requirements. At the same time, outlet PM concentrations are kept far below regulatory limits.  Pilot testing and laboratory results confirm the catalytic filter approach.  Systems can also be configured to comply with the CISWI standards, removing PM, SOx, NOx, dioxins, and other pollutants using a single system.  Tri-Mer Corporation, the largest supplier of catalytic ceramic filter systems in the world, has numerous large installations in a variety of U.S. industries.
