Some of these questions include:

• Are my compliance objectives being achieved?
• Am I minimizing costs?
• Have alternatives been adequately assessed?
• Is my full-scale system cost-effective?
• Have balance of plant issues been adequately addressed?

What Apogee can do for you....

• Make Sure You Got What You Paid For - Obtain a thorough evaluation of your installed PAC system and verify its operation according to your specifications (load following, feed rate ranges, etc.). Also obtain a better understanding about balance of plant issues associated with PAC systems.
• Establish the Most Cost-Effective Sorbents - Conduct parametric and long-term tests on all commercially available sorbents at your sites. You will be provided with the most complete sorbent performance curves and information to gain the required reduction at the least cost with respect to both vapor-phase mercury capture and impact on fly ash sales.
  
  In addition, Apogee can economically interface our portable PAC injection system into your permanent PAC system that will enable quick sorbent evaluations using 1000-lb super sacks of prospective sorbents without the need to empty hard PAC silos and ordering tanker quantities of test sorbents.
• Confirm Optimal Injection Locations - Quantify the benefits or effectiveness of PAC injection upstream and/or downstream of air heaters (hot- and cold-side injection) as well as across electrostatic precipitators and baghouses.
• Evaluate Sorbent Distribution Efficiency - Confirm the sorbent distribution efficiency throughout the duct and its impact on mercury removal rates.
• Confirm Operations of Plant Mercury Monitors - Temporarily install a redundant CMM to confirm mercury data from current plant monitors and to establish mercury concentrations upstream of PAC mercury control systems.

Apogee Qualifications:

• We have over ten years experience in mercury monitoring and controls and have made over 30,000 hours of mercury measurements at a wide variety of plants burning bituminous, subbituminous, and lignite coals throughout the country.
• We own and maintain four field-ruggedized and portable CMMs that are each capable of measuring from two distinct sampling channels or locations.
• We own and operate a portable injection system that features real-time loss-of-weight load cells to accurately establish sorbent feed rates.
• We developed the original mercury sampling hardware from which were developed the manual mercury sorbent trap Appendix K and Method 30B procedures.
• We designed and developed full-scale manifold and sorbent injection lances for permanent PAC systems at over twenty power plants.
• We revolutionized the way vapor-phase mercury is measured by developing the patented Quick Silver Inertial Separation (QSIS^TM) Filter. This technology is utilized by the major commercially available CMM systems.
• We also developed a patent-pending Dry Sample Conditioning System that converts total vapor-phase mercury to vapor-phase elemental mercury for measurement purposes and can operate in high selenium flue gas streams.

• Experience: Take advantage of Apogee's unique experience in the mercury field that no other group can match.
• Professionalism: Apogee respects our colleagues and competitors and will provide you with an honest assessment of any potential product or system.
• Quality: We promise quality, accurate mercury measurements that provide insight and answers to your mercury questions.
• Scheduling: We use flexible scheduling to meet your timing and requirements.
