LO-CAT® process for sulphur recovery / odor control

The LO-CAT® Hydrogen Sulfide Oxidation System provides economical H2S removal to solve odor problems quickly and effectively. LO-CAT achieves H2S removal efficiencies exceeding 98%. The system also eliminates costly once-through chemicals, offers unique mobile bed contacting material, and reduces operating costs. Turnkey systems from specification to installation can be developed to meet stringent schedules. We also offer technical service and support.

LO-CAT systems provide proven, cost-effective solutions to H2S odor problems for a wide range of air flows and H2S concentrations.

Systems utilize a unique mobile bed contracting material which eliminates plugging and cleaning problems found in other chemical scrubbers. Chemical costs with LO-CAT systems are the lowest of any odor control process—5 to 10 times lower, in fact. It regenerates and reuses dual chelated iron catalyst material, rather than requiring expensive once-through chemicals.

The LO-CAT process also eliminates liquid blow-down with salt or spent caustic, as well as solid absorbent that may require special handling or additional treatment. Instead, it produces a sulfur cake which is readily acceptable for landfill applications.
