AITESA participates in design, manufacture, supply, installation and commissioning of HTF Ullage system for ACCIONA Energy´s 50 MW Solar Thermal Plant in Orellana la Vieja, Badajoz.
The Ullage system consists mainly of air condensers, absorption filters, condensing exchangers, condensation tank and light and heavy waste tanks. Also included are the valves, structure, brackets and pipes required for integration into the plant´s system.
AITESA´s turnkey services also include the supply of: Basic and detailed engineering, inspection and monitoring, workshop testing of equipment, transportation, assembly and other services.
The purpose of this supply package is to clean thermal oil in 3 phases: High Boiler Treatment, Low Boiler Treatment and purification of Vents.
The system receives two process streams, one from the expansion tanks vent and another corresponding to intermittent extraction of hot HTF from the plant.
The removal of heavier elements (High Boiler) is performed in a flash tank, while lighter ones (Low Boiler) consisting mainly of phenol and benzene are separated from incondensable elements through condensers. Finally, vents leading to the atmosphere are treated with activated carbon filters to ensure that emissions comply with environmental legislation.
The system is expected to be operational in mid-2012.
