Description: Das Projekt "Reduction of energy consumption in the process industry by pervaporation with inorganic membranes: techno- economical feasibility study" wird vom Umweltbundesamt gefördert und von Technische Hochschule Aachen, Lehrstuhl und Institut für Verfahrenstechnik durchgeführt. General Information: The general objective of the project is to study and evaluate the feasibility of inorganic membranes and inorganic membrane technology in pervaporation processes for application in the process industry in order to reduce drastically the energy consumption in these industries by substitution of conventional separation processes like distillation by pervaporation with inorganic membranes. The implementation of reliable pervaporation processes, based on stable inorganic membranes could lead to energy savings of more than 50 per cent as compared to conventional separation technologies, in particular distillation. For EU-I 6 full implementation of pervaporation could result in energy savings of approximately 400 PJ/year (= 840 MECU/year). Other advantages claimed are: - purer products, thus higher product quality, - increased throughput, thus cheaper production, - simplified (downstream) and/or novel processes, - less organic wastes and organic emissions through recycling of solvents, - avoidance of the use of entrainers in azeotrope breaking, - less emissions of CO2, SO2 and NOX. The approach is based on a combination of: - availability of applicable inorganic membranes; - inorganic membrane manufacturing and optimization expertise; - detailed knowledge of separation and pervaporation processes and, - process know-how on the relevant chemical production processes. The project will focus on four carefully selected cases in the following application fields: i) ether production ii) extraction of aromatics from hydrocarbon mixtures iii) ester production and iv) dewatering of solvents. These fields are representative for a large group of processes. The work comprises detailed technical and economic evaluations of the feasibility of the applications of pervaporation with several types of inorganic membranes by a combination of experimental laboratory and bench-scale studies i.e. membrane, reactor/separator and process testing, process modelling, system integration and design studies. With respect to the membranes, the first focus will be on tubular silica membranes, which are available on a sufficient scale, in a high quality and in proper modules. Performance data for pervaporation application for a number of component mixtures are already at hand. Other types (zeolite, carbon) are explored as well. Process specific inorganic membrane development and optimisation is foreseen. Attention will be paid to vapour permeation as alternative technique for the (limited) cases in which the available inorganic membranes prove to suffer from fouling or have insufficient durability Aspects such as membrane performance (flux, selectivity) in the specific applications, durability, producibility and full-scale chemical process pre-designs will be covered. Finally energy savings and costs reductions as compared to conventional options will be adressed. ... Prime Contractor: Netherlands Energy Research Foundation, Energy Efficiency; Netherlands.
