CONTUFILT-RN
Raney Nickel Catalyst Filtration
Raney Nickel Catalyst filtration in hydrogenation is one of the trickiest filtration processes in the chemical industry. The alkaline pH makes the catalyst very sticky and slimy, causing filters to choke instantaneously. CONTUFILT-R is specifically designed for this challenging application. It uses our proprietary vacuum-fused open channel media to handle these issues with ease.
With 35 years of experience in system engineering, we have developed CONTUFILT-R Raney Nickel Catalyst filters featuring vacuum-fused open channel proprietary media. This design offers high permeability and low-pressure drops, giving CONTUFILT-R an edge over other filters.
Process Operation​
- The system uses filter candles made from vacuum-fused open channel proprietary media, ideal for Raney Nickel Catalyst filtration.
- Filter candles are arranged on a tube bundle within a housing for effective filtration.
- The system performs filtration functions including in-situ reverse flow, washing, and gas-assisted discharge to handle collected Raney Nickel catalyst particles.
- The cake is collected in a semi-solid form or sent as a slurry, and the candles are cleaned and prepared for the next operation.
- A zero hold-up bottom design ensures complete removal of liquid from the vessel, crucial for API manufacturing where GMP standards do not allow mixing of batches or any liquid hold-up. This design achieves full liquid recovery and purges the Raney Nickel Catalyst out of the system without the need for opening the system or creating slurry.
Technical Specification ​
- The filter housing is made of SS 316 and includes nozzles for inlet, outlet, drain, backwash fluid, vent, and pressure taps, with suitable connection sizes and types as per flow parameters.
- The housing is designed and fabricated according to the ASME Boiler Pressure Vessel Code, Section VIII, Division 1 for safe operation.
- Special non-destructive testing requirements such as radiography, liquid penetrant inspection, magnetic particle inspection, and leak testing can be specified and are charged extra.
Features and Benefits ​
- Efficient cake release for seamless removal of cake material, simplifying maintenance and enhancing operation.
- Advanced filter construction with vacuum-fused open channel filters made of SS316L or special nickel alloys like RNC-Grade Elements for robust filtration.
- Choke-free structured matrix design prevents choking issues and maintains smooth filtration processes.
- Closed operation preserves catalyst lifespan by preventing air contact, resulting in longer catalyst life and increased efficiency.
- Safe operational environment with a design that prioritizes personnel and equipment safety.
- Leak-free operation ensures no spillage and minimizes wastage and mess.
- No need for filter-aids, streamlining the filtration process.
- Zero hold-up design for efficient heel filtration and thorough filtration without wastage.
- High catalyst recovery per batch for optimized yield and improved return on investment.
