The Tech Inc. Closed Catalyst Candle Filter Skid separates hydrogenation catalysts such as palladium on carbon and Raney nickel from reaction mixtures inside a closed vessel. The catalyst is held on filter candles, washed and discharged as a slurry under nitrogen, so operators are not exposed to the solvent or to pyrophoric catalyst.

Main components

Pressure vessel with sintered metal or cloth-covered filter candles
Nitrogen blowback system to release the cake from the candles
Slurry discharge valve to a closed catalyst receiver
Feed, filtrate and wash connections with sight glasses
Differential pressure and pressure instruments
Stainless skid with valves arranged for operation from one side

Applications: API and fine-chemical hydrogenation, catalyst recovery, and pilot and production reactor bays.

Closed Catalyst Candle Filter Skid

Single candle filter – one vessel for batch filtration.

Twin filters – two vessels for continuous operation.

Pilot size – small vessel for kilo-lab and pilot plants.

Packaged with the hydrogenation bay – supplied with gas panels and samplers.
Design pressure: to client specification

Design code: ASME VIII, or client specification

Materials: SS316L, or to client specification

Candles: sintered metal or cloth-covered, grade chosen for the catalyst

Blowback: nitrogen, with automatic or manual sequence
Operator safety – catalyst and solvent stay inside a closed vessel.

Catalyst recovered – precious-metal catalyst collected for reuse or refining.

Less handling – cake washed and discharged without opening the filter.

One supplier for the bay – filters, gas panels and samplers from one supplier.
Established manufacturer – part of the Davey Group since 1990, exporting to more than 110 countries.

Everything under one roof – in-house mechanical fabrication, electrical works, PLC and SCADA automation, and R&D.

Complete scope – design, supply, installation, commissioning, factory acceptance testing (FAT) and site acceptance testing (SAT).

Trusted by Saudi Aramco – an established supplier to Saudi Aramco.

Certified management systems – ISO 9001, ISO 14001 and ISO 45001, with CE marking.

Close to your project – offices in Chennai (India), Toronto (Canada), Tallinn (Estonia) and Al Khobar (Saudi Arabia).

For this product – we build the hydrogenation bay kit, closed samplers and high-pressure reactors, so the candle filter fits the rest of the bay.
Engineering to your P&ID, data sheets and company standards; drawings submitted for approval before manufacture; factory acceptance testing (FAT) with client or third-party inspection; export packing and full documentation dossier; installation, commissioning and site acceptance testing (SAT); operator training, spares and after-sales support worldwide.
