The Fluidized Bed Technology of Schwing Fluid Technik GmbH / Procedyne Corp., USA has made tremendous progress during the recent years. By using advanced materials and their combinations, combined with the advantages of the fluid bed technique, specially in the field of high temperature processing, possibilities now exists which allow meeting the expectations of exciting developments in the new centennial.

In the past, chemical reactions of powders with gases, especially at temperatures up to 1200°C could only be realized with extraordinary expenditures; and for the typical fluid bed applications like calcination, tempering, dehydration, reduction, oxidation, and other gas/solid reactions, the pilot and commercial systems were very expensive and none flexible. The interest in intermediate to high temperature material processing has increased during the recent years. This will continue in future considering the developments in catalyst manufacturing, advanced materials for high-tech industry, and ceramic products.

The fluidized bed technique has been used successfully for years, especially for moderate to high temperature (300-1200°C) applications.

An important factor for good fluidization is the design of the gas distributor plate. The larger the contact area between gas and solids, the more useful is the fluidized bed technique. With the Procedyne designed and patented gas distributor plate, a proven system has been designed which meets the highest demands of fine solids processing including temperatures up to 1200°C, temperature uniformity, and controlled atmosphere. Powders of very fine particle size can be fluidized perfectly at low gas velocity.

As important as the gas distribution system is the separation of solids from gas. Our latest filter system design, Mikro-Dyne™, guarantees that dust (> 1 µm) remains in the reactor, providing essentially the complete product yield. We offer internal, as well as external fines retention process gas filters capable of operating at temperatures up to 850°C for entrained solids removal from process gas streams.

Fluid bed reactors are supplied by Schwing Fluid Technik GmbH / Procedyne Corp., USA as a single component or as a complete system. Customer requirements determine the reactor configuration and the scope of the system supply.

Fluid bed reactors of various configurations are available to meet our Customer's processing needs. We have successfully designed and supplied fluid bed batch reactors, back-mixed continuous reactors, plug-flow continuous reactors, and horizontal multi-stage continuous reactors for moderate to high temperature (1200°C) applications. The retort may be electrically heated or natural gas heated (direct or indirectly fired).

We also offer Process Gas Filters to 850°C, Process Gas Heaters to 1090°C, and highly efficient Gas-Gas Heat Exchangers.

Systems can be designed and supplied as a single component or complete systems including controls, gas conditioning, energy reclamation, etc. Our systems are planned, designed, and manufactured according to CE requirements.
