TAMS Multi-Pollutant Emissions Control Technology

Novacon Energy Systems developed a process to reduce air pollutants produced by the burning of coal, waste materials, petroleum and other fuels used in power plants, industrial boilers and many other commercial applications. The process reduces the production of Sulfur dioxide, Oxidized Mercury, Sulfur Trioxide, and Unburned Carbon released to the atmosphere for clean coal technology.

It can also assist in improving combustion efficiency and the plant’s production capacity, adding to overall plant profits.

The Novacon Energy Systems TAMs Sorbent Process involves the introduction of a unique Calcium-based  sorbent directly into the combustion zone of the furnace through  simple pneumatic injectors.

Novacon’s development of the use of our patented TAMs sorbent demonstrates to the industry our ability to revolutionize in-furnace sorbent technology. The uniqueness of the process lies in its ability to reduce emissions to a higher degree at lower cost than other technologies now in use.

TAMs are capable of being used at very high combustion temperatures without sintering or losing efficiency and therefore can be used in a wide variety of combustion systems operating at temperatures from 1,600f to 2,600f. It is scalable for use in any size or type furnace, including Circulating Fluidized Bed, Pulverized Coal, Stoker Grate, Rotary Kilns, and industrial process combustors.

We are capable of reducing Sulfur Dioxide by over Ninety Five percent in CFBs at very low Calcium to Sulfur ratios, while simultaneously reducing carbon in ash by at least 30% and oxidized Mercury by over 75%.

We can reduce Sulfur Dioxide by 70 to 80 percent in PCBs at a Ca/S ratio of 2. Higher reductions may be attained, by simply feeding more sorbent to the boiler.

Low Capital, low operating cost, low maintenance cost, and lower labor costs, equals higher profits.

The Novacon Energy Systems TAMs Multi-Pollutant Emissions Control Technology and Solutions provides that elusive combination of high performance, low cost, and flexibility that the industry has sought for decades.

  • 1. Novacon Energy Systems, Inc. The TAMS Flue Gas Multi-Pollutant Control System For conventional utility boilers, TAMS holds the promise of extending the useful life of the plant while simultaneously reducing emissions and meeting higher future demand for electric power at competitive prices. For smaller utility boilers it would allows for substantial emissions Reductions without the high capital, labor, maintenance, and Operating costs associated with scrubbers. For Circulating Fluidized Bed combustors it would significantly reduce costs, increase efficiency, increase plant output, and provide for very high emissions reductions without additional capital investment. TAMS very low capital cost significantly reduces the financial risks of facilities planning and pollution control cost containment strategies. It may be used in any type of combustor and is applicable to Waste to Energy plants, Paper manufacturing, and many other industrial applications.

    • Fuel transportation cost can be as much as half of total cost
    • Local higher-sulfur coals can be used in place of low sulfur coals that may have to be shipped from thousands of miles away from the plant
    • Blending coals to achieve emissions standards is expensive, both from a capital equipment and labor viewpoint
    • Low sulfur fuel is available at higher cost, as compared to the TAMS process used with higher sulfur fuel
    • In many cases it would reduce the need for importing low sulfur coal or shipping fuel long distances, preserving coal mining jobs, while creating new ones in limestone mining, transportation and processing.

White Paper Catalytic Bag Houses for Multi-pollutant Control

The need for a Superior Sorbent

The evolution of air pollution control technologies that combine catalytic filtration with dry sorbent injection (The Catalytic Bag House, or C.B.H.) promises to be the preferred method for dealing with acid gases such as SO2, NOX, and particulates. The technology is being applied to coal –fired power plants, waste-to-energy facilities, steel mills, and in many other industrial applications.

The process has proven to be a better choice than wet or dry scrubbers, especially when used in older plants. Its primary advantages are a much lower capital cost, greater heat recovery benefits, and the potential for higher performance than scrubbers.

U.S., energy policy is not yet well defined, However, new Power, Waste to Energy, and other industrial facilities take many years to plan, permit and build.  Cleaner fossil fuel power is an indispensible bridge towards the creation of a modern and more efficient energy system.

Using the Paris Environmental Accord as a template, the rest of the world is moving forward rapidly. The main problem facilities are facing in complying with more stringent pollution control standards, are the costs involved in adopting new, cleaner technologies.

The C.B.H. process, coupled with a far less costly sorbent, would be an excellent solution since it provides that rare combination of low capital and operating cost and high efficiency. This would allow coal-fired and Waste to Energy plants to substantially reduce pollutants at a fraction of the cost of a scrubber.

For older plants and in emerging economies, where coal is, and will remain, the main source of energy for many years, the marketplace for an economically sound solution will undoubtedly expand dramatically.

In a study released by The N.Y. Times in July 2017, 1600 new coal-fired plants will be built over the next decade throughout the world. Conservative estimates concluded that  coal powered energy will INCREASE by 43%

The main impediment towards adopting Catalytic Bag House technology on a wider scale is the high cost of the special sorbents required! Both Hydrated Lime and micronized Trona cost between $140-160.00 per ton- F.O.B. mine or production facility.

Shipping costs can be very high as well. For example, the largest Trona deposit is in Wyoming: Often Thousands of miles from an object plant

We have developed a Calcium Carbonate based sorbent that is more efficient, has a much higher temperature tolerance, exhibits less fouling, and is:


The process is fully developed and has been run successfully for thousands of hours in power plants and Waste-to-energy facilities. The Pulverized Coal efficiency curves are shown below. Our sorbent is injected directly into the boiler, and is capable of operating at temperatures well in excess of 2,500f.

TACC Sorbent

As shown, TACC sorbent is 12.5 % more efficient than Hydrate in capturing SOX, as well as being able to operate efficiently within a wider range of operating temperatures. Partial loads have no effect upon the process due to the flat curve surrounding its ideal injection temperature of 2,450f.
