Product Description
ZX Series Candle Filter for Chemical Solvent & Catalyst Recovery, 0.5-100μm Filtration
The ZX Series self-cleaning candle filter provides a fully enclosed, automated solution for chemical solvent purification and precious metal catalyst enclosed recovery. Designed for hazardous and volatile chemical environments, it ensures zero solvent vapor emissions while delivering reliable, repeatable filtration performance. Customizable with ATEX-certified components for Zone 1/Zone 2 hazardous area operation, it is ideal for Pd/C, Raney Nickel, and Pt/C catalyst recovery in hydrogenation and fine chemical synthesis processes.
Key Features
- ATEX Explosion-Proof Enclosed Design: Fully sealed system with optional ATEX-certified motors, instruments, and control panels prevents solvent vapor release into the atmosphere, ensuring safe operation in Zone 1 and Zone 2 classified areas.
- Compound Filter Element: Multi-layer sintered metal mesh candles provide deep-bed filtration with excellent chemical resistance for aggressive solvents, acids, and alkalis.
- Precious Metal Catalyst Recovery: Achieve catalyst recovery rates exceeding 99.5% with integrated cake washing and drying. Closed-loop design minimizes Pd/C, Raney Nickel, and Pt/C catalyst losses during hydrogenation and coupling reaction workups.
- Nitrogen Backflush Dry Cake Discharge: Inert gas backflush ensures safe, dry cake discharge for pyrophoric or moisture-sensitive catalyst residues. Sealed discharge chute connects directly to containment vessels.
- One-Pass Complete Filtration: Eliminates recirculation steps, reducing processing time and solvent exposure risks in batch chemical manufacturing.
- PLC Full Automation: Remote-controlled operation minimizes operator exposure to hazardous chemical environments, with recipe management for different products.
Applications in Chemical Industry
- Hydrogenation catalyst recovery (Pd/C, Pt/C, Raney Nickel)
- Activated carbon decolorization and spent carbon removal
- Fine chemical intermediate purification and polishing
- Solvent recovery, dehydration, and polishing filtration
- Polymer and resin melt filtration with high-viscosity handling

Frequently Asked Questions
Q1: Can the ZX Series handle hazardous solvents like hexane or THF?
Yes. The fully enclosed design with optional ATEX-certified components is engineered for flammable solvents. Nitrogen-purged backflush and sealed operation prevent vapor release, ensuring safe processing of Class I flammable liquids. Custom ATEX configurations are available for Zone 1 and Zone 2 hazardous areas.
Q2: What catalyst recovery rate can we expect for Pd/C and Raney Nickel?
Typical precious metal catalyst recovery rates exceed 99.5% with the ZX Series candle filter. The integrated cake washing displaces residual process liquid from the catalyst cake, and controlled drying further reduces solvent content, maximizing recoverable catalyst value while minimizing waste disposal costs.
Q3: Is the system compatible with high-temperature chemical processes?
Yes. Standard configurations handle up to 200°C using SS 316L construction. For higher temperatures or aggressive acidic/chlorinated media, Hastelloy C276 or other specialty alloys are available as customization options.
Q4: How is the dry cake discharged safely for pyrophoric Raney Nickel catalysts?
The system maintains a nitrogen atmosphere throughout the discharge cycle. The sealed cake discharge chute can be directly connected to a water-filled quench tank or inerted containment vessel, ensuring pyrophoric catalyst residues are never exposed to air during transfer.
