2 Technology That Meets the Challenge The Thermo Scientific Arke SO 3 System, with built-in SO 3 generator, uses an advanced Quantum Cascade (QC) Laser-based platform to provide high sensitivity, optimum selectivity and a continuous, direct measurement of SO 3 within tough industrial-plant process environments.

3 Why Monitor? The continuous monitoring of Sulfur Trioxide (SO 3 ) in an industrial-plant process is critical in driving process control decisions. A by-product of coal combustion, SO 3 is most noticeable when resulting in a Blue Plume, an effect caused by light scattering through condensed droplets of sulfuric acid at the stack exit. Continuous SO 3 monitoring, through correlation with the opacity of stack emissions, forestalls the risk of Blue Plume, mitigating the risk of associated expenses and potentially adverse public opinion of the plant. The presence of SO 3 can hinder the capture of mercury by Activated Carbon Injection (ACI) systems. The SO 3 adheres to sorbents, displacing mercury that may otherwise have been captured. Monitoring the level of SO 3 allows the fine-tuning of the ACI systems, and consequently helps determine an optimal sorbent injection strategy. Despite the negative impact on the effectiveness of ACI systems, SO 3 can create a contrary effect that actually enhances mercury capture by decreasing the resistivity of fly ash and improving the efficiency of fly ash capture at the Electrostatic Precipitator (ESP). The trade-off between the performance of the ACI system and the ESP requires precise and continuous monitoring of SO 3 to help determine the optimal levels needed to maximize overall mercury capture. Monitoring and limiting SO 3 levels within the process can also prolong the life of plant equipment. The acidic nature of SO 3 can cause corrosion of equipment, resulting in more frequent maintenance, repair and ultimately causing heavy capital expenditure due to premature equipment replacement. SO 3 is also known to react with Ammonia (NH 3 ) slip, creating deposits of Ammonium Bisulfate, which can plug air heaters. These adverse effects emphasize the importance of continuously monitoring SO 3 levels at different locations in the plant process. increased sensitivity maximum selectivity

4 The Arke SO 3 System can help balance the trade-offs between material use and plant performance. Benefits of Continuous Monitoring Determining precise levels of SO 3 is vital to improving the efficiency of various control methods employed to limit acidic gases in the flue gas stream. Sorbent injection systems typically utilize many tons of dry sorbent powder, such as soda ash, or hydrated lime, to mitigate SO 3 in the process. A well-designed closed-loop control system, which includes the Thermo Scientific Arke SO 3 System, can minimize the amount of expensive sorbent injected into the process, and produce significant cost savings. In addition, limiting the amount of sorbent also prevents the plugging and fouling of plant equipment. In coal-fired plants that use low-sulfur coal, SO 3 injection systems work to improve the efficiency of the ESP. In other applications, there is a wide range of SO 3 control methods including fuel blending, alkali injection at the outlet of the SCR and wet FGDs. The use of these methods, in conjunction with the Arke SO 3 System, can help you balance the trade-offs between material use and plant performance. Arke SO 3 System

5 Product Solutions Removing the guesswork associated with manual methods and sorbent injection, the Arke SO 3 System provides true continuous SO 3 monitoring capabilities, which can assist you in optimizing your control systems. Utilizing an advanced QC Laser-based platform, the Arke SO 3 System maximizes the sensitivity and selectivity of SO 3 measurement, minimizing interferences with Sulfur Dioxide (SO 2 ) and water. Designed to operate anywhere within the plant process, the Arke SO 3 System is a comprehensive, easy-to-integrate system, complete with an advanced software program that is compatible with standard DAS or DCS programs. The Arke SO 3 System is calibrated by an SO 3 generator that is integrated into the probe. Using proprietary technology, the SO 3 generator produces precise and verifiable concentrations of SO 3 calibration gas through the oxidation of SO 2. The SO 3 generator has a high conversion efficiency, which is validated by the ability of the system to measure both SO 3 and SO 2. System calibration is accomplished by injecting SO 3 into the inertial filter near the point of extraction. Additionally, the probe is designed with a spiking port to bypass the filter and induce dynamic spiking to look for measurement bias, a critical feature to ensure reliable readings. System includes: 9800 SO 3 Analyzer 9805 Dilution Extractive Probe with built-in SO 3 generator The sample-measurement bench utilizes a QC Laser that allows excellent SO 3 detection and optimum selectivity. The measurement system reduces absorption line broadening, which limits the spectral features of SO 2 or water from overlapping with the SO 3 features. As a result, the spectral resolution has been determined to be one to two orders of magnitude better than the alternative spectroscopic methods.

Utilizing an advanced QC Laser-based platform, the Arke SO 3 System maximizes the sensitivity and selectivity of SO 3 measurement, minimizing interferences with Sulfur Dioxide (SO 2 ) and water.
