SHIP2FAIR – Martini & Rossi: integration of Solar Heat in Industrial Process – Preliminary evaluation

Abstract

SHIP2FAIR is a H2020 European funded project†, which aim to foster the integration of solar heat in industrial processes from the agro-food sector facilitating the integration of solar heat production in low temperature processes. Based on the assessment of the industrial process for the production of different spirits and the local solar potential in Pessione plant (TO) of Martini & Rossi – one of the four demosite of the project -, the preliminary results that guided the choice of the most suitable solar collectors (Fresnel) and the definition of the thermo-economic parameters for the solar plant are hereby presented. The preliminary assessment takes into account different perspectives from the industrial and economic point of view: the availability of suitable surfaces, the economics of the investment and the best processes to be fed by solar produced steam towards a preliminary techno-economic feasibility study. The starting points for the analysis have been the characterization of the thermal demand in terms of necessary temperature level (°C), overall consumption and time distribution. The following step has been the identification of the suitable collectors to be installed taking into account the thermal parameters presented before, the boundary conditions of the industrial facility (e.g. space available, orientation, etc.), the technical characteristics of the collector itself and the solar irradiation available considering the plant’s location. Moreover, the complex thermal facility in the factory, constituted by multiple (3) gas boilers and a Combined Heat and Power (CHP) plant in two different but linked pressurized steam loops, is taken into account for the definition of the solar collectors configuration and their integration via the proper management of heat generators and storage. The calculations are based on the expected thermal (steam) production guaranteed by the solar collectors and avoided GHG based on the reduction of gas fired boilers consumption.
