Industry News: SCHWING Technologies Presents Fluidized Bed Process Technology at ACHEMA 2018

Vist SCHWING Technologies’ booth at ACHEMA to learn about the latest solutions in production processes

01 Jun 2018


From June 11 to June 15, 2018, SCHWING Technologies will once again be presenting innovative applications and production solutions for its Fluidized Bed Process Technology at the leading ACHEMA trade fair. In Booth C4 of Hall 4, SCHWING experts Ralf Sonnen, Michael J. Robinson and Julian Nienhaus will provide information on the latest solutions in production processes involving metal oxides, powders, catalysts and supports, pigments, additives, and novel materials. The low-maintenance and energy-efficient fluidized bed reactors from SCHWING provide consistent, reproducible, and efficient material processing in the food, cosmetic, and pharmaceutical industries, as well as many others.

Current application examples include energy storage, batteries and carbon-based superconductors in the electric automotive industry and renewable energy sector. “Reliable storage solutions are becoming more and more important in that sector,” stresses Ralf Sonnen, expert in Fluidized Bed Process Technology at SCHWING. “Our fluidized bed reactors often provide the optimal processing solution for the contents of these storage areas: fine powders, granulated solids, or component mixtures.” Through thermochemical implementation, the SCHWING Fluidized Beds ensure controlled, uniform handling and consistent product quality of the particulates.

SCHWING Fluidized Bed Process Technology


SCHWING’s Fluidized Bed Technique delivers excellent heat-transfer characteristics and transforms the bulk behavior of individual particles into an actively mixing, liquid-like solids/gas mixture. Michael J. Robinson is Head of Fluid Bed Process Technology at SCHWING and goes on to explain: “Our special plant design aims to create a gently mixing and non-abrasive solids bed in a gas-rich environment. We achieve this by using a proprietary gas distribution plate specially configured to the candidate material, which makes available a large surface area for exchange between gas and solids. Advantages include energy-efficient conversion as well as high gas utilization and high product yield.”

SCHWING Fluidized Bed Process Reactor


When components, compounds, and precursors require uniform processing and homogenous quality, the SCHWING Fluidized Bed Process Reactor is an interesting alternative to a rotary kiln, shaft furnace, or tray oven. “Our customers benefit from our many years of experience in the high-temperature thermal and chemical treatment of powders and granules,” points out Test Development Center Manager, Julian Nienhaus.

“Our plant concept is transferable to reactors with elevated pressures, temperatures up to 1100°C and a variety of process gases such as nitrogen, hydrogen, hydrogen chloride and ammonia, as well as reactant gases for chemical vapor deposition (CVD), such as hydrocarbons and silanes.”

Testing and pilot plants for safe scale-up


At its headquarters in Neukirchen-Vluyn, SCHWING offers all interested customers the opportunity to test new processes in 4 to 120 liter reactors at elevated temperatures or pressures for experimental purposes to establish the optimal process conditions. Based on an initial fluidization analysis in SCHWING’s lab, bench scale experiments under reaction conditions can be performed, and can then be further optimized in the scaled up pilot plant. The data gained is used to design customized production systems. Depending on requirements, customers can also use the SCHWING’s Tolling Center for contract toll-processing.
