The Nexus approach in the process industry in times of energy turnaround
What is being implemented only slowly or only through the pressure of statutory regulations at local authority level has long since found its way into many production sites of process-oriented industries. Rising raw material prices and costs in wastewater disposal make the treatment and reuse of process water and process wastewater and the recovery of auxiliary and process materials an economically attractive challenge for companies.
In the wake of the energy revolution and the expansion of decentralized electricity production from renewable energies, the initial situation is changing: Whereas electrochemical processes – above all for the chemical synthesis of basic chemicals – were previously considered uneconomical because of their power requirements, they are gaining in importance in times when electricity from fluctuating sources (wind power and photovoltaics) which is not needed at the moment is driving down prices on the electricity exchanges.
