Your catalyst is worth more than the batch. Stop losing it to the filter.

Up to 99 percent single-pass recovery of precious metal catalyst, using asymmetric dual-layer Clarysynt sintered elements as a positive surface barrier. Single-pass operation matters: it eliminates the multi-pass recirculation that older systems rely on, which shortens batch time and reduces catalyst attrition. For your specific slurry we establish the recovery figure in a bench or pilot trial before you commit.

Sparkler filters and open filtration steps expose the batch and the operators, lose fines below their retention capability, and consume filter aids and cloths every cycle. A closed sintered-metal circuit captures fines down to 0.5 micron, recovers the heel through an integrated heel filter, needs no filter aids, and returns the same elements to service for thousands of batches. The saving is counted in recovered metal, not in filter spend.

Yes. Raney nickel duty runs as a fully closed circuit under nitrogen blanketing, with no atmospheric exposure of the pyrophoric catalyst at any point in the cycle, including cake discharge. Safety interlocks are engineered into the automation, not left to procedure.

Elements regenerate in place by reverse-flow gas or liquid backwash on an automated cycle. Design life is up to 10 years or more per element set; some elements in continuous service have run beyond 5,000 batches. Actual life depends on the process fluid, catalyst, temperature, cleaning protocol and operator discipline. Because Clarysynt media is manufactured in-house in Ahmedabad, replacement elements and rebuild support do not wait on an import.

At 200 hydrogenation batches a year, losing 2 percent of a Pd/C charge per batch adds up to tens of lakhs of rupees a year in metal alone, before the reactor hours lost to multi-pass filtration and the disposal of catalyst-laden pads as hazardous waste. The number depends on your loading and the metal price, so we calculate it from your batch record.

Yes. We make drop-in replacement elements for sintered metal candles from other manufacturers, matching dimensions, end connections and seal configuration, so they fit the existing housing. Where the fine-rating dual-layer construction applies, lower differential pressure means less mechanical stress on the catalyst and less attrition into fines.

SS 316L is standard, with SS 304 where it suits. Hastelloy C-276 for strong acids and chloride environments, Inconel 600 for high-temperature oxidising service, Monel 400 for reducing environments, titanium for strong oxidising acids, and zirconium for sulfuric acid service. Send the process fluid, temperature and pressure for a recommendation.

In the anthraquinone process a palladium catalyst is suspended in the working solution during hydrogenation and must be separated before the oxidation stage. A sintered metal system captures the catalyst in a single pass, backwashes it for reuse, and passes clear working solution forward; a primary plus polishing arrangement is typical for the filtrate clarity H2O2 plants need.

Element replacements are typically quoted at 6 to 8 weeks, standard-design systems at 8 to 10 weeks, and custom-engineered systems with special alloys, large sizes or code-stamped vessels at 8 to 12 weeks. The lead time for your order is confirmed with the quotation.

Yes. Sintered metal elements and catalyst recovery systems have been exported to customers in the USA, Europe, the Middle East, Africa, Southeast Asia and Australia, with export documentation and sea or air freight packing.
