A centrifugal separator (1) for separation of liquid particles from a gas stream, comprising a stationary frame (2), a gas inlet (3) and a gas outlet (4). The frame comprises a tubular element (24) defining a rotor space inside itself and a liquid transportation space (39) outside the tubular element. A centrifugal rotor (5) is arranged in the rotor space and rotatably supported in the frame around a rotational axis (x) and comprising a separation means (6). A stationary device (10) is configured to bring the gas stream in rotation, thereby bringing the rotor (5) into rotation. At least one opening (40, 41) is provided in the tubular element, between the rotor space and the liquid transportation space, for conducting liquid separated from the gas stream from the rotor space to the liquid transportation space.

SINFONIA utilizes EU funds to bolster public/private resources and provide European added value to already committed district refurbishment master plans of two middle sized European cities (Bolzano, Italy and Innsbruck, Austria), the targeted performances of which combine three key features thanks to industry involvement: i) unique cooperation between the cities belonging to the same climate zone in Europe, but working under different regulatory regimes (Austria, Italy), ii) single collective ambition in reducing energy needs to meet human activity requirements, and the related CO2 emissions (40 to 50 % primary energy savings per district, 20 % increase of the share of renewable energy uses), iii) several innovations in network infrastructures and technology interfaces that enable smarter use of energy at district level, a stepping stone to guarantee a reliable and progressive transition toward low carbon cities. Moreover, SINFONIA aims at validating a comprehensive, interdisciplinary, refurbished city district model where the potential for scalability and replication by middle-sized European cities is built and validated during demonstration, based on energy technologies deployed by the two pioneer cities. This model emphasizes the role of an innovative integrated energy system approach, linking energy efficiency and CO2 abatement. The model robustness is reinforced by five early adopter cities which are full project partners in Cyprus (Pafos), France (La Rochelle), Germany (Rosenheim), Spain (Sevilla) and Sweden (Bors). They use the tested scalability and replication rules to reinforce their impacts on the five future city district refurbishment processes, thus showing that district renovation can be prepared under different sizes, climate and regulatory conditions (Scandinavia, Central Europe, Atlantic, and Mediterranean). A robust exploitation plan with a complete European perspective is then designed involving replication cluster cities and industry.

The use of renewable resources in the process industries is socially desirable and a market pull for products has started to develop in recent years, but renewable products have to compete with identical or similar-in-application products based on fossil raw materials in terms of quality and production cost. One of the main reasons for currently higher production costs of products based on renewable resources is that the production routes involve processing complex dilute aqueous solutions from which the desired products have to be separated during downstream processing. Consequently, a major challenge the process industry is facing, is the development of cost- and energy-efficient water removal and product-recovery techniques. Today downstream processes for products based on renewable resources are often developed using methods from the petrochemical area being insufficiently adapted to the new applications. A re-thinking of downstream process development and the development of suitable methodologies for a fast-track development of tailored downstream processes as well as the optimisation of separation technologies are urgently needed in order to unlock the potential of the renewable-based product market for the European process industry. PRODIAS addresses this challenge by developing and implementing: - a toolbox of highly innovative, cost-effective and renewable-tailored separation technologies; single technologies and/or hybrid systems - novel, optimized apparatus and machinery to enable for and host the developed technologies - in combination with an integrated design approach for the fast-track selection of appropriate technologies. The main advantages of the PRODIAS toolbox and integrated design approach for processes based on renewable resources are - significantly decreased production cost - increased productivity and efficiency - faster process development and commercialization - significantly lower energy consumption leading to less CO2 emmissions.
