Abstract: A process and its relating plant for thermal conversion of aluminum chloride hydrate into aluminum oxide and gaseous hydrogen chloride. In a first step, aluminum chloride hydrate is fed into a decomposition reactor where it is heated to a temperature between 120 and 400° C. Afterwards, the partially decomposed aluminum chloride hydrate is finally calcined to aluminum oxide at a temperature between 850 and 1200° C. in a second reactor. The aluminum chloride hydrate is admixed with aluminum oxide in an intensive mixer with a mass ratio between 1:1 and 10:1 aluminum chloride hydrate to aluminum oxide for using a fluidized bed reactor as a decomposition reactor.

Abstract: The invention relates to a system and a method for storing electrical energy which are based on a closed thermodynamic cycle. They make it possible to store electrical energy in a very efficient, cost-effective, and safe manner. No environmentally hazardous or expensive materials are required. The system comprises a compressor, a turbine, and two packed-bed storage units which are operated at different temperature levels. In order to load the packed-bed storage units, the cycle is operated as a counterclockwise heat pump process. In this process, the heat generated at the outlet of the compressor is expanded at a high temperature level into a first packed-bed storage unit and stored therein. The “cold” produced during the subsequent expansion of the gaseous working medium in a turbine is stored in a second packed-bed storage unit. This requires mechanical energy which is provided by an electrical machine. In order to discharge the energy storage system, the cycle is operated in reverse (i.e.

Abstract: A method, an installation and a system for processing optical workpieces in which workpieces are conveyed to individual processing apparatus or processing lines corresponding to an assignment. The respective assignment preferably takes into consideration assignment parameters, such as the availability and capability of processing apparatus and/or processing lines. The assignment that already has been carried out is examined before the actual or ultimate conveying and/or when there is a change in the assignment parameters and optionally is changed in a corresponding manner, taking into consideration the current assignment parameters, in order to adapt to current circumstances. As an alternative or in addition, jobs for processing workpieces are forwarded to the processing installations at different sites based on corresponding assignment parameters. Optionally, an examination and, as appropriate, a change in the assignment are made when new jobs or significant changes in the assignment parameters are detected.
