2 Environmentally friendly For high temperature applications, AQYLON s organic working fluids have a very low Global Warming Potential (320). Rugged AQYLON s ORC modules are designed for durability and fit into standard containers, allowing for modular deployment. Efficient AQYLON s ORC modules apply cutting edge technology to maximize efficiency according to the heat source. AQYLON holds four patents related to turbines and ORC technology, and eight more are pending. Heat recovery from industrial installations AQYLON s ORC modules convert waste heat contained in exhaust fumes and other industrial processes such as water loops and thermal oil loops into electricity. When the heat to drive the ORC cycle comes from waste process heat or exhaust fumes, the industrial process as a whole is unaffected. Electrical network or factory grid Aero water chiller Industrial building AQYLON ORC module ORC heat recovery: Flue gas from industry When recovering exhaust fumes, a heat exchanger (boiler) must be placed on the chimney to collect the heat and transfer it to a thermal oil loop that will feed the ORC module.

3 Create value from your exhaust streams Most industrial plants have exhaust streams that can be valorized. AQYLON proposes to produce electricity through heat recovery on the exhaust streams in: Cement factories Steel mills Foundries Glass furnaces Aluminum smelters Plants treating sewage through incineration Incinerators all heat generating plants These industries can all improve their global energetic efficiency by installing our ORC modules to simultaneously decrease both pollution and energy bills. In the figure above we can see a heat exchanger with its bypass, placed on the fumes of glass factory. The heat is sent to the ORC trough a thermal oil loop. Dry coolers are used for the cold loop of the ORC. ORCs can also be used to cool water or replace coolers. For example, in some incinerators, the fumes are cooled down with a boiler + water loop + coolers system before being processed. In this case, the coolers can be replaced by an ORC, making it possible to generate power instead of consume power to cool the fumes. This process not only generates power but also eliminates the parasitic loads of the coolers.

We also propose direct condensed solutions (when the coolers are directly condensing the working fluid) Reliable and decentralized energy The organic fluid is vaporized in the evaporator(1) and then supplied to the ORC turbine(2) that drives a generator(2), producing clean and reliable power. The vaporized fluid enters the regenerator(2) to give its remaining energy to the liquid organic fluid. The steam is then condensed in a condenser(2) which is supplied with cooling water. The condensed fluid is then pumped(3) into the regenerator(2) and finally into the evaporator(1) to close the circuit. AQYLON ORC modules are preassembled in our facility workshop near Paris in two 40ft containers for the 1MW unit.
