Emanuela Mangiaracina
Location: Palermo, Italy
Position: Master's Student in Process Engineering at University of Palermo
Emanuela Mangiaracina is a passionate student of chemical and biochemical engineering at the University of Palermo, where she completed her bachelor's degree. Currently, she is pursuing a master's degree in process engineering at the same institution.
Emanuela's research is focused on energy recovery from natural saline gradients. Her work within the SEArcularMINE project involves testing and optimizing the performance of Reverse Electrodialysis (RED) technology at a pilot scale, utilizing the SEArcularMINE Second Generation prototype stack. This technology employs ion exchange membranes to achieve separation based on the charge of ions dissolved in a solution, converting ionic flux into electric current through redox reactions at the electrodes when connected to an external load resistance.
In her experiments, Emanuela tested the RED equipment and explored different configurations to enchance efficiency, including single-circuit, two-circuit, and four-circuit tests. Her efforts led to achieving a maximal gross power density of 5 W/m² and a maximal efficiency of approximately 26%.
Working in the pilot plant environment presented numerous challenges, but Emanuela found it immensely rewarding to collaborate with fellow project members and overcome these challenges to meet project objectives. This experience has been a source of personal growth and inspiration, solidifying her commitment to contributing to sustainable practices, particularly in achieving circularity to reduce waste.
Emanuela's enthusiasm for the SEArcularMINE project stems from its innovative approach and alignment with circular economy principles, which are crucial in today's environmental landscape. Looking forward, she aspires to pursue a career in the chemical industry, preferably focusing on bioenergy and biofuel sectors, where she can continue to apply her expertise and passion for sustainable engineering solutions.
