How confident are you that you have the right chemicals?

Meeting state and federal compliance levels for mercury is challenging, especially when you’re managing more than just mercury. Are you adding chemicals to the coal or gas stream? Have you considered the impacts of chemicals on:

  • Boiler operation or tube life
  • SCR catalyst life
  • Corrosion
  • Ancillary stack emissions
  • Leaching from ash
  • Wastewater treatment impacts
  • All-in costs (including balance-of-plant impacts)

ADA M-Prove Additive Family

Our M-Prove Additives enhance mercury removal across a range of coal types and air pollution control devices. Our goal is to introduce just enough chemical to achieve target mercury emissions while minimizing impacts on your plant, providing a cost-effective alternative to other halogen-based coal additives used for mercury control.

M-Prove Coal Additive: Our flagship product

  • Effective with low halogen, subbituminous coal to achieve high mercury control while minimizing corrosion and other balance-of-plant risks often associated with halogen addition.
  • Effective with higher halogen, higher sulfur coal-fired units to achieve mercury trim control, especially when other mercury control technologies are ineffective.
  • Effective at extremely low chemical treatment rates
  • Significantly reduces the balance-of-plant risks attributed to other halogen-based coal treatments
  • Minimizes ancillary halogen emissions in the stack, fly ash and wastewater
  • Reduces sorbent consumption for ACI systems
  • Facilitates enhanced mercury removal by other downstream pollution control devices (ESP, FF, WFGD)

M-Prove 35 Blend

  • Proven technology on multiple configurations
  • Similar performance to calcium bromide (CaBr2)
  • Alternative to bromine mercury control products
  • Competitive pricing backed by ADA-ES expertise

An Experienced Approach

ADA provides solutions for challenging industry problems. In the late 90’s, we discovered that halogen was required to achieve high mercury removal in plants firing subbituminous coals. We also know that adding too much halogen to a plant designed to burn low halogen coals can cause costly, unintended impacts to metal surfaces that come in contact with flue gas.

Our patented M-Prove Additives were developed to provide the benefits of halogen for mercury control, without the negative impacts. We use halogen blends that can be applied at very low levels. This essentially eliminates the risk associated with halogen injection while achieving similar mercury control benefits.

Proven Results

Experiences from current users of our M-Prove Additive show:

  • Application rates up to 10 times lower than other halogen-based coal treatments
  • Significant reduction in halogen concentration in scrubbers or effluent associated with coal additives or brominated activated carbon due to very low treatment rates
  • Reduced risk of corrosion typically associated with high halogen addition rates
  • Reduction in costs associated with activated carbon injection through reduced carbon usage or lower quality requirements

Over 200 million tons of coal treated with no corrosion or balance-of-plant issues

Ease of Implementation

M-Prove Additive and M-Prove 35 Blend are liquid coal additives that can be applied at various stages of the coal feed process. We understand that adding a chemical to your process requires thoughtful consideration to minimize risks to the plant.

We assist you in evaluating our M-Prove Additives through:

  • Discussions with our technical experts
  • Full-scale testing using a portable system with minimal disruption to normal operations

We offer simple, low capital options to implement the M-Prove Additives. The injection equipment includes a simple, skid-¬based design with a small footprint.

  • Injection equipment available for purchase or lease
  • Existing coal additive systems can easily be modified to add M-Prove Additives

ADA – Your Trusted Advisor

ADA assists plants by helping identify the best solution for unit-specific operations. We evaluate many factors affecting mercury removal to help you determine the optimal control strategy for your plant. Key factors include:

  • Coal properties, including halogen, sulfur and mercury content
  • Boiler operation, load profile, flue gas temperatures, etc.
  • Emissions control equipment and operating practices
  • Relative costs and potential performance limitations of various control strategies
  • Potential balance-of-plant impacts
  • Environmental regulations for plant discharges (air, water, solids)

Our team has supported plants evaluating mercury control options since 1990, including conducting mercury control demonstrations at more than 100 plants. We developed mercury control technologies to reduce operating costs and potential balance-of-plant impacts. We have internationally recognized mercury control experts on staff. Put our expertise to work for you to save money and reduce risks of non-compliance.
