The Indus3Es project received funding under H2020-EE-18-2015: New technologies for utilization of heat recovery in large industrial systems, considering the whole energy cycle from heat production to transformation, delivery and end use. Funded under the Grant Agreement 680738, the main objective of the project is to develop an economically viable solution for industry, appropriate for existing plants and adaptable to various industrial processes, consisting on the technology of Absorption Heat Transformer. The developed system will be demonstrated in real environment in Tu¨pras, the main petrochemical industry in Turkey, enabling to analyze besides integration aspects, operational and business issues. Indus3Es System will be defined and optimized for different specificities in different sectors and industrial processes, for which up-scaling of the demonstrated technology and replication studies will be performed. Indus3Es is a project funded by the European Commission. This project has received funding from the European Union’s Horizon 2020 Research and Innovation program under Grant Agreement n° 680738.
