Real-Time Acid Dew Point Measurement for Process Control
Breen Energy Solutions understands the unique application requirements of the mining & metals industry and develops robust solutions to meet them. The Breen Probe can measure acid dew point in real time for process control.
Avoid excessive formation or condensation of weak acid
Metals are typically found in nature in the form of ores comprised of a chemical compound of the metal with other elements, such as oxygen (as an oxide), sulfur (as a sulfide) or carbon and oxygen together (as a carbonate). In the case of carbonates and sulfides, a process called “roasting” drives out the unwanted carbon or sulfur, leaving an oxide which can be directly reduced. Roasting is usually carried out in an oxidizing environment. The metal oxide is then “smelted” into the metal.
The Breen-ADM Acid Dew Point Monitoring System is ideally suited for these applications to measure the dew point of weak acid in the process. This measurement can then be utilized to modify operating conditions, such as sulfation air or process temperatures, to avoid excessive formation or condensation of weak acid. Shown below is an application of the Breen-ADM System to control sulfation air in the waste heat boiler in a copper smelting process.
