Abstract
The purpose of this paper is to present the design, the manufacturing and the commissioning of the heat exchangers (HEX) of the Rittershoffen geothermal plant. This plant is located in the Rhine graben and is design to deliver a power of 25 MWth to the “Roquette Frères” bio-refinery at Beinheim. Operating conditions of these heat exchangers are particularly aggressive. Different types of heat exchangers (plate, tubular…) and also several material options were available on the geothermal equipment market. The choice of these units and that of the downhole production pump posed a technical challenge for this project.
