#FTPL1501
Overview
Fowlerex was engaged to develop a concept design for a high-temperature baghouse solution as part of a treatment plant project supporting a uranium calciner operation at an African mining site.
The treatment process generates continuous high-temperature process gas containing valuable dust material. The objective of the system is to capture and recover dust prior to atmospheric discharge, supporting environmental compliance while also enabling recovery of commercially valuable product material.
Scope of Work
Fowlerex was responsible for developing a concept-level engineering design for the proposed dust capture system, including:
• High-temperature baghouse filtration concept
• Induced draft fan selection and airflow control strategy
• Gas cooling and temperature management methodology
• System monitoring concept including broken bag detection
• Redundancy and emergency shutdown considerations
• Integration concept with client treatment plant process
Challenges and Engineering Solution
The main challenge is to cool down the process gas coming from the calciner at a temperature of about 800°C to a temperature of about 200°C that the baghouse can handle.
To address this, Fowlerex developed a dedicated ambient air intake to dilute and cool process gas prior to filtration, supported by induced draft fan control and continuous bag integrity monitoring. The ambient airflow is achieved by an induced draft fan, which forms part of our proposed solution.
In addition to emission control, the system is designed to recover dust material with significant commercial value. Engineering calculations indicate potential recovery yields capable of generating ongoing operational return while reducing environmental discharge.
We have also proposed a broken bag detector on the exhaust side to permanently monitor baghouse operation.
The project is currently in the conceptual engineering phase, with potential progression to equipment supply and system integration in future project stages.
