Glatt Ingenieurtechnik GmbH

Glatt, the pioneer of fluid bed and spouted bed technology for bulk solids processing, will be presenting cutting-edge safety concepts at POWTECH 2023 in Nuremberg (Germany) that go far beyond current legal requirements. As a plant manufacturer and operator, Glatt combines professional engineering with extensive technological know-how from its own practical experience. Visitors to the stand can discover which comprehensive concepts and innovations Glatt has developed and how they pay off in terms of product quality, fire/explosion protection, operational safety, heat recovery and environmental compatibility.

Glatt takes a holistic approach to planning new facilities and converting existing ones. This not only focuses on optimal particle design, but also ensures sustainable operation, especially in bulk materials processing industries. In addition to optimised space concepts and complete building solutions, Glatt’s expertise extends to waste and environmental management, energy concepts and the handling and containment of toxic and highly active substances.

Hygienic design and product safety

Particular attention is paid to hygienic and safe production, especially in the food sector and for items destined for the consumer market. Glatt has implemented robust processes in production facilities to meet the requirements of the Global Food Safety Initiative’s Food Safety System Certification 22000 (FSSC), which minimises product liability in the event of damage.

Glatt specialists take structural and conceptual aspects into account, as well as the process itself, to develop new concepts for the dust- and contamination-free handling of highly active toxic products, for example. Design improvements such as securing individual components against overpressure-induced bursting are also part of the process and make cleaning and maintenance work on fluidised bed and spouted bed systems significantly safer for employees.

Tailor-made explosion protection

Glatt offers various explosion prevention devices and measures that have been assessed theoretically and subsequently proven in practical tests. Ignition sources are avoided as far as possible, all parts are earthed and an appropriate plant design is chosen to ensure maximum safety. Customers can select from the most appropriate option, whether that’s explosion suppression, pressure relief, inert gas or vacuum operation.

At the Glatt Technology Centre in Weimar, not only are tests done on the production and functionalisation of powders, granulates and pellets, but further trials are run to optimise the process. Safety-relevant processes can also be tested at laboratory scale before being used in production.

“Our many years of experience as a plant manufacturer and operator enable us to offer our clients customised safety concepts that meet their specific requirements. We focus on forward-thinking action and stand for maximum protection, efficiency and quality in bulk solids production,” says Dr Michael Jacob, Head of Process Technology at Glatt Ingenieurtechnik.

We are looking forward to your visit!

Lecture on: Aerosol-based processes for the production of battery materials

27.09.2023 | 15:00 – 15:30 | POWTEC stagetalks I,  Halle 4, Stand 4 -100

Speaker: Arne Teiwes, Glatt Ingenieurtechnik, Lecture in English language

What to learn: With the introduction of the lithium battery by Sony in 1990, the development of active materials has gone through a steady process with the aim of increasing energy density. This is realised through the development of novel, nickel-rich and cobalt-free cathode materials, the production of silicon-carbon composite materials and the development of solid-state batteries. The increasing demand for applications within electromobility or stationary energy storage requires the implementation of novel, sustainable and continuous manufacturing processes as well as processes for coating active materials. Aerosol-based methods based on spray drying / spray calcination and spray granulation are presented using selected examples. First results on electrochemical characterisation are shown.

Lecture on: Pulsed multiphase flows – Investigation of the influence of frequency and amplitude induced flow conditions

28.09.2023 | 9:40 – 10:00 | PARTEC 2023 Hall Tokio, NCC Ost

Speaker: Arne Teiwes, Glatt Ingenieurtechnik, Lecture in English language

What to learn: Although the benefits of pulsed multiphase flows and the associated potential to intensify heat and mass transfer processes, e.g. for drying, extraction or chemical reactions, have been known for some time, industrial implementation is still limited. This is mainly due to a lack of understanding of the fundamental factors such as the amplitude and frequency of the pulsating flow and the resulting particle dynamics. With the aim of process intensification and targeted control of sub-processes, or even the development of completely new process routes for the formation, drying or conversion of particulate solids in pulsating gas flows, a basic understanding of the transport processes occurring is becoming increasingly important. In the present study, the influence of different flow conditions and particle properties on particle dynamics and the resulting agglomeration behavior is investigated. With the help of CFD flow simulations and unilaterally coupled modelling of gas-particle micro-processes by DEM, parameter dependencies are highlighted. These provide a basis for better control of product particle properties resulting from pulsation conditions during the proprietary powder synthesis process by spray pyrolysis or spray calcination of Glatt Ingenieurtechnik GmbH.

Lecture on: Thermal processing of particles for innovative powder materials

28.09.2023 | 11:10 – 11:30 | PARTEC 2023 Hall Tokio, NCC Ost

Speaker: Dr. Johannes Buchheim, Glatt Ingenieurtechnik, Lecture in English language

What to learn: Established powder technologies, such as fluidized bed processes, were typically run at temperatures between room temperature and 200°C. This appropriate for a lot of materials which might even be damaged or destroyed by higher temperatures. On the other hand, certain materials processed that way, will need a subsequent thermal treatment to achieve the desired chemical composition or crystalline structure. As every additional process will produce supplementary costs and handling efforts, thermal processes that can combine the particle formation and thermal treatment turned out to be very beneficial for these applications. Within the presentation different high temperature powder treatment processes should be explained and their benefits shown on different examples.

Poster on: Recovery of valuable materials from sewage sludge ashes – Phosphorus recycling for the production of compliant fertilizers

Authors: Johannes Buchheim, Arne Teiwes, Michael Jacob; Glatt Ingenieurtechnik GmbH, Weimar/Germany

PARTEC 2023 Poster Session

Introduction: Phosphorus is essential as a macronutrient for plants and for the production of fertilizers for use in agriculture. In the future, phosphorus as a critical raw material must be increasingly recovered through recycling and returned to a new use. Due to the increasing tendency to thermally recycle phosphorus-containing sewage sludge, more phosphorus-containing sewage sludge ash is produced, which can be seen as a raw material for the production of phosphorus-containing fertilizers. In urban areas, sewage sludge ashes often have elevated heavy metal contents. To prevent excessive input into the environment, heavy metal removal is necessary.

Technical implementation: With the PHOS4green process, Glatt Ingenieurtechnik GmbH has developed an innovative patent-protected process with which the essential and sought-after nutrient phosphorus can be recovered from sewage sludge ash and used for new phosphate or compound fertilizers. To date, this process can be used to produce fertilizers from sewage sludge ashes that meet the quality requirements of the German Fertilizer Ordinance (DüMV, Annex 2) and EU-V 2019/1009. Economical heavy metal depletion increases the raw material potential of the available sewage sludge ashes. The PHOS4green process, which has been modified with regard to heavy metal depletion, thus provides greater planning security with regard to possible future stricter limit values or strongly fluctuating ash loads.In the course of this event, strategies for the reduction of heavy metal contents will be presented.
