Process and plant innovation for the sustainable production of edible oil
Salov has always worked to reduce the environmental impact caused by its production activities in particular, refining. In 2011 Salov decided to participate in the INNOVOIL project – the acronym intended to suggest INNOVATION in process and plant for the sustainable production of edible OIL.
Supported by the Region of Tuscany and implemented in partnership with ENERTECH SRL, with the collaboration of the University of Pisa and the Consortium of the Magona di Cecina technological center, the objective was to create an intervention plan for innovative production process technologies –aiming to reduce energy consumption, material use and waste production.
The key phases of the project were:
- The characterization and analysis of each phase of the refining process, aiming to increase the sustainability of the process by reducing energy and material consumption
- The design and implementation of a pilot plant reproducing each phase of the refining process
- The extension of the equalization section of the waste water treatment system to project the plant from any raw material variability
- Heat recovery from within the process to meet the system’s energy needs
- Recupero e riciclo di condense, precedentemente utilizzate in ciclo aperto, per la produzione di vapore
- Valutazione del rischio di esplosione nella fase di stoccaggio della materia prima e durante la lavorazione in seguito all’accumulo di solvente residuo dal processo di estrazione
- The implementation of a simulation of the refining process (with the ASPEN HYSYS simulator) to quantify the energy requirements in the various plant sections, identifying opportunities for the energy recovery and saving
- The analysis of the environmental impact of the process using the LCA methodology (life cycle assessment, UNI EN ISO 14040-14044) to verify improvements in the environmental sustainability of the process
