A West Australian mineral processing plant approached HydroChem with a complex task. The internal surfaces of a gas scrubber were showing
signs of severe scaling. The significant level of scaling was restricting regular flow and leading to elevated temperatures and low pressure drops.
Downtime for rectification work was limited to a brief annual maintenance shutdown. The HydroChem team recommended a chemical clean of
the scrubber system with the commitment to performing the work in the required time frame.
As the scrubber had never been cleaned previously, a thorough technical evaluation and operational review was carried out. HydroChem developed a new set of procedures to ensure the complex task was carried out safely, effectively and within the rigid timeframe allocated.
The successful clean removed an estimated 1,360kg of calcium salts from the scrubber circuit.
