Sweco has carried out an extensive energy study in close collaboration with Vynova on the open cooling water system at their site in Tessenderlo. The resulting energy efficiency measures contribute to achieving the sustainability targets of the chemical concern.
Project: energy study and measurement campaigns on open cooling water system
Client: Vynova Belgium
Period: 2019 - 2020
This energy study is part of Vynova's EPA commitment (Energy Policy Agreement), within which the company makes year-on-year efforts in the field of energy efficiency. The depth of the study considered illustrates the efforts energy-intensive companies are making today in order to continue to achieve additional efficiency gains after a long process of energy efficiency programmes.
The electrolysis department’s cooling water system is an energy-intensive component of the site (primary pumps of 500 kW). Based on the electrical, hydraulic and thermal measurement campaigns and analyses carried out throughout this energy study, a significant technical and economically feasible savings potential has been identified. The savings measures mainly focus on (dynamic) cooling water flow and pressure reduction, optimisation of pump efficiencies and speed control of cooling tower fans.
