Standard industry tests for activated carbon are not specifically adapted for mercury control applications. The Dynamic Mercury Index test is developed to specifically measure PAC performance in mercury control use cases.
You can learn more about Dynamic Mercury Control and how it can deliver better results for your plant in this paper by Chris Vizcaino and Sheila Glesmann hosted on Cemnet.com.
The US Maximum Achievable Control Technology (MACT) mercury (Hg) limit is regulated to 55lb Hg/Mt clinker on a 30-day rolling average. To stay in compliance with these limits, many cement plants carry out dry injection of powdered activated carbon (PAC) into the flue gas stream in a process known as activated carbon injection (ACI).
Each plant comes with its own set of unique challenges and the Dynamic Mercury Index test provides the findings necessary to make mercury compliance performance tweaks specific to your application.
