Porous Metal Powder Sintered Stainless Steel Filters Catalyst Recovery

Porous Metal Powder Sintered Stainless Steel Filters Catalyst Recovery

The Micron Porous Metal Filtration System is used in petroleum and chemical production processes for high-efficiency separation of all liquid-solid and gas-solid. The metal powder sintered microporous metal filter element, which is commonly constructed of 316L stainless steel powder, and 304 stainless steel powder, forms the basis of the system. While maintaining the filtration effect, attaining the lowest pressure drop and highest backwashing recovery rate, this porous metal filter can adapt to the increased process temperature and pressure of refineries and chemical plants.

The 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, and can avoid frequent replacement and disposal of waste filter material to prevent environmental pollution.

Why Recycle Catalysts

TOPTITECH Sintered Metal Catalyst Filter is a specialized system that utilizes catalysts for recovery and purification. Catalysts play an essential role in modern chemical industries, with approximately 80% to 85% of chemical production processes utilizing catalysts to speed up reaction rates and improve production efficiency.

Recycling deactivated catalysts has become necessary, particularly for metal catalysts. The TOPTITECH catalyst filter is designed to recover catalysts through automatic filtration and concentration, magnetic separation, fine filtration, and membrane separation. The economic benefits of TOPTITECH catalyst filters include reducing expensive material losses, improving product quality, reducing waste product discharge, meeting green environmental standards, reducing maintenance cycle and cost, reducing energy consumption, and improving recovery and purification rates.

Traditional coarse separation of catalysts typically employs sink tanks or vacuum filters, which are low cost but occupy a large area. Furthermore, their filtering area is vertical, leading to an uneven thickness of the cake, making it easy to crack and difficult to wash, filter material, filter cloth wears fast, and easy to block. They are extremely troublesome to use, and processing settling speed is not high, consuming a lot of time and labor, greatly increasing the total cost of investment. Compared to traditional processing equipment, cluster sintered metal filters can be used for flammable and explosive gases, toxic body powder, soft particles, deformable solids, high solid content filtration, and has a high dirt holding capacity. It can be completely used as centrifugal equipment, drying equipment pre-stage equipment.

Working Principle

The catalyst-containing liquid material enters the sintered filter from the outside and passes through the filter material before entering the filter. A filter cake is created when impurities that are bigger than the filter pores are caught and collected on the surface of the filter material. The filter cake can collect certain smaller water pollutants by bridging. When the contaminants reach a specific level, the import and export fluid valve closes, the compressed gas enters, and the filter cake is dried as the differential pressure increases to the system-set value. During the back-blowing procedure, the back-blowing gas pollutants are released, and the filter cartridge is renewed.
