Slurry Atomization Anomaly Detection in Spray Dry Absorbers

Presented by: Stewart Nicholson – Primex Process Specialists

Many dry scrubbers are equipped with dual fluid nozzle systems for slurry atomization.  Nozzle malfunction in these systems can compromise slurry atomization resulting in excessive material accumulation in SDA hoppers, ductwork and fabric filters.  Related effects on safety, reliability and operating cost can be substantial.  At one facility, material accumulation within the SDA hoppers decreased significantly after implementation of a new method to detect nozzle malfunction. When combined with other operational improvements, this detection method has also helped reduce lime consumption, fly-ash production and maintenance costs. This paper will be presented as a case study describing the situation, solution, results and lessons learned.

Advanced Monitoring in Tight Windows

Presented by: Michael-Paul Jenkins – Gecko Robotics

What if there was a better way to monitor vessel thickness in scrubbers in between major outages?

Failure of dry scrubbers in the industry are well documented. We know that these vessels are exposed to corrosive and erosive environments in normal operating times. To get ahead, many utilities monitor wall thickness in spot checking during maintenance outages. These outages are usually very quick and because of this, not everything that should be monitored, can be. Time, funds, and access prohibit thorough inspections.

However, what if there was a way to monitor dry scrubbers in these tight windows that can not only monitor wall loss, but also lend insight into causes and possible solutions?

This presentation will cover the history and modern take on monitoring assets within tight turnarounds/windows, explore Rapid Ultrasonic Gridding (RUG) for liners, identify advantages and disadvantages of robotic inspection methods, and cover a case study with advanced monitoring and data-dense inspections.


If anyone has any questions for the speakers please let us know and we will be happy to follow up and try to get responses for you!

2021 In-Person Conference Cancelled – Monthly Webinars Will Continue

The DSUA remains focused on the health and safety of our attendees, partners, and conference staff.  We all anticipate and enjoy our time sharing, learning, and socializing during conference week.  Unfortunately, due to the events related to the COVID-19 pandemic and the uncertainty of how long quarantine and social distancing guidelines will remain in place, the board has elected to cancel the in-person conference for 2021.  We will proceed with monthly webinars in 2021 similar to what DSUA did in 2020 in an effort to continue sharing dry scrubbing knowledge and experience in a virtual format until we feel it is appropriate to resume an in-person conference.  DSUA hopes that by the end of 2021 we have better clarity on our plans for 2022.  We look forward to your participation in the 2021 DSUA webinars!  Please don’t hesitate to contact us with any questions, comments, concerns.
