Are your filters
choking instantaneously?
Raney Nickel Catalyst
filtration in hydrogenation is one the trickiest filtration in the chemical
process Industry. Alkaline pH makes the
catalyst very sticky and slimy and chokes filters instantaneously. CONTIFILT-R
is designed specifically for this application. happens with ease using our
proprietary vacuum-fused open-channel media.
35 years of experience in system engineering has helped us
design CONTUFILT -R – Raney Nickel Catalyst filters with vacuum-fused open
channel proprietary media. The USP of these filters is a highly porous
structure, which is characteristic of an open-channel fused media. This gives
an edge over other filters in terms of high permeability and hence low-pressure
drops.
Process Operation
The system comprises filter candles made up of our Vacuum fused open channel proprietary media, suitable for Raney Nickel Catalyst. Candles are placed on a tube bundle in a housing. The system performs specific filtration functions, in-situ reverse flow, washing, and gas-assisted discharge of collected Raney Nickel catalyst particles. The cake is collected in semi-solid form or is sent as a slurry. The candles are clean and ready to use for the next operation. The new ZERO HOLDUP bottom design ensures that complete liquid is removed from the vessel, very important for API manufacturing where GMP does not allow the mixing of batches, nor any liquid holdup is permitted. Full recovery of liquids is achieved, and the Raney Nickel Catalyst is purged out of the system without opening the system or slurried and sent back to the reactor.
Technical
Specification
The filter housing is made of SS 316 with Nozzles for the inlet,
outlet, drain, backwash fluid, vent, and pressure taps with suitable connection
sizes and types for proper operation as per the flow parameters specified. The
housing is designed and fabricated, generally in accordance with the ASME
Boiler Pressure Vessel Code, Section VIII, Division 1. as a result we get very
safe operating systems. Testing if required: Special requirements for
non-destructive testing like radiography, liquid penetrant inspection, magnetic
particle inspection, leak testing, etc. should be specified as required and are
charged extra.
