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)

We developed a coal additive that enhances mercury removal in plants firing low-halogen fuel. It introduces just enough chemical to treat the mercury without impacting your plant. We’ve treated over 100 million tons of coal without any reported issues.

ADA M-Prove Additives

Our M-Prove™ Additives provide a cost-effective alternative to other halogen-based, coal additives used for enhanced mercury removal. Our product minimizes corrosion risks to cut maintenance and repair costs, enhancing system reliability. M-Prove™ Additives also reduces additional halogen that could leach from your ash, or be present in the wastewater treatment system.

Key Benefits

  • Effective at extremely low chemical treatment rates
  • Significantly reduces the balance-of­-plant risks attributed to other halogen­ based coal treatments, including corrosion
  • 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)
  • Minimal capital investment

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 sub-bituminous 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 that comes in contact with flue gas.

Our patented M-Prove™ Additives was developed to provide the benefits of halogen for mercury control, without the negative impacts. We use a form of halogen 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

Our observations from current users of M-Prove™ Additives show:

  • Up to 85% reduction in mercury emissions achieved without activated carbon
  • ACI sorbent rates often more than 60% lower
  • Application rates typically 1/10 of other halogen-based coal treatments
  • Over 100 million tons of coal treated with no corrosion or balance-of-plant issues
  • Minimal application rates, which results in less ancillary emissions from facility effluent streams

Ease of Implementation

M-Prove™ Additives 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 them determine the best solution for their 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.
