Catalyst Recovery Filters

A catalyst is any substance that induces a chemical reaction without participating in it directly, remaining unchanged post-process. The use of catalyst filtration systems, including precious metal catalyst filters, to effectively trap and reclaim catalysts like platinum and palladium can significantly enhance your system’s efficiency, reduce waste, and cut costs. Mott’s three precious metal catalyst filters are meticulously engineered to capture +99% of catalysts for recycling or reclamation, ensuring superior filtrate quality. The Mott HyPulse® LSI is perfect for various clean-in-place backwashes, from discharging an approximate 15 wt.% slurry to an approximate 50 wt.% wet cake. For capturing submicron particles, the HyPulse® LSX cross-flow filter ensures less than 50 ppm filtrate quality, preventing media blinding by small catalyst particles. Meanwhile, the HyPulse® LSM excels in applications with dense particles like Raney nickel, combining configurable filtration and backwash operations with gravity settling for high solids loading streams. All three technologies, designed for precise process conditions, can endure operating temperatures up to 1700°F, high operating pressures, and corrosive environments, making them invaluable for systems utilizing precious metal catalysts.

Mott LSI filters for catalyst processes are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or through a backwash cycle.

Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned.
