HYDECAT OPTION


In contrast to traditional methods of hypochlorite destruction, the HYDECAT™ process offers a simple, low cost, highly reliable, extremely efficient and environmentally friendly solution. It can also be used to improve the operability, performance and safety of an existing chemical reduction system, whilst significantly reducing the running costs.

The HYDECAT process is a modular, fixed-bed technology which can quickly and easily be retrofitted or integrated into the operator’s existing plant. It is designed to provide maximum efficiency with minimum maintenance.

Containing no moving parts, a HYDECAT module requires little supervision or upkeep.

The supported nickel HYDECAT catalysts are extremely resistant to compounds which traditionally poison nickel catalysts. They have a long active lifespan. If performance declines after several years’ service, the catalyst can easily be replaced with minimal downtime. Patented HYDECAT process modules are designed for easy loading, unloading and inspection, and to allow safe catalyst and effluent handling.

The HYDECAT process can operate continuously, decomposing hypochlorite concentrations of up to 15% wt to any required outlet concentration (<1ppmw) in a single pass. The reaction is mildly exothermic (H = 60 kJ/mol, 15 kcal/mol) and the HYDECAT process operates at low temperatures, 10-50 °C (50-120 °F) in the pH range 9-14. It can also lower the chemical oxygen demand of effluent streams.
