Porous Metal Powder Sintered Stainless Steel Catalyst Recovery Filters for Catalyst Recovery Process

A brief introduction to the working principle of catalyst filter (sintered filters) equipment: HENGKO Sintered Metal Catalyst Filter uses catalysts to recover and purify. We know that catalysts occupy an extremely important position in the modern chemical industry. According to statistics, about 80% to 85% of chemical production processes use catalysts to speed up the reaction rate and improve production efficiency.

Recycling deactivated catalysts have become necessary, especially for metal catalysts. The HENGKO catalyst filter is a catalyst recovery and purification system that recovers catalysts through automatic filtration and concentration, magnetic separation, fine filtration, and membrane separation. The economic benefits of HENGKO catalyst filters are

1、Reducing expensive material losses
2、Improve product quality
3、Reducing waste product discharge and meeting green environmental standards
4、Reduce maintenance cycle and cost
5、Reduce energy consumption
6、Improve recovery rate and purification rate

Traditional coarse separation of catalysts generally uses sink tanks or vacuum filters. This equipment is low cost and occupies a large area. By day its filtering area is vertical. Uneven thickness of the cake, easy to crack, not easy to wash, difficult to filter material, filter cloth wears fast, and easy to block, extremely troublesome to use, processing settling speed is not high, consuming a lot of time and labor, greatly increasing the total cost of investment. Compared with the traditional processing equipment, the cluster sintered metal filters can be used for flammable and explosive gases, toxic body powder, soft particles, deformable solids, high solid content filtration, and its high dirt holding capacity, completely as centrifugal equipment, drying equipment pre-stage equipment use.

Working principle:
The material liquid with a catalyst enters from outside the sintered filter and passes through the filter material from outside to inside. The impurities larger than the filter holes are intercepted and accumulate on the surface of the filter material to form a filter cake. Through bridging, the filter cake can capture some finer impurities in the water. When the impurities accumulate to a certain extent, the differential pressure rises to the system-set value, the import and export fluid valve closes, and the compressed gas enters and dries the filter cake. The back-blowing gas impurities are discharged in the back-blowing process, and the filter cartridge is regenerated.

Product Describe

Micron porous metal filtration system is used in petroleum and chemical production processes for all liquid-solid and gas-solid high-efficiency separation, the core of which is the metal powder sintered microporous metal filter element, typically made of 316L stainless steel powder, Hastelloy, titanium, etc. This porous metal filter can adapt to the higher process temperature and pressure of refineries and chemical plants, and ensure the filtration effect while achieving the minimum pressure drop and maximum backwashing Recovery rate.

Micron porous metal filtration system in petrochemical production has the characteristics of high-temperature resistance, high-pressure drop, high solid content operation; liquid (gas) and solid high-efficiency separation; system internal backwashing to remove solids; continuous automatic operation; also can avoid frequent replacement and disposal of waste filter material to the environment pollution.

Applications:

      Recovery of precious metal powder and precious metal catalyst
　　CTA, PTA, and catalyst recovery system in PTA production
　　Coal to olefin (MTO) catalyst recovery system
　　Filtration of oil slurry and circulating oil in the catalytic cracking unit
