Abstract der Vorlesung

Den folgende Text haben die Vortragenden bereitgestellt.

SynErgie is one of the four Kopernikus projects led by the German Ministry for Education and Research (BMBF). The partners in SynErgie develop technologies and digital tools for the flexibilization of the energy system, focused on flexibilizing the demand side, i.e., the industrial consumers. This lecture presents key findings concerning the chemical and process industry from the first eight years of SynErgie. The lecture begins with a brief review of the German electricity market. We will introduce the concept of demand-side management (DSM), which can exploit fluctuations in the energy supply through flexible plant operation. The lecture will further provide an overview of the different levels of decision-making required to flexibly operate a chemical plant while considering safety and feasibility limitations. All theoretical concepts will be explained through their application to the energy-flexible operation of air separation units (ASU) developed in cooperation with Linde AG. The lecture will show detailed results for the operation of the ASU and discuss techniques for the real-time applicability of DSM. In a second example, we will discuss a biodiesel plant and show how process modifications such as buffer tanks can be used to decouple the dynamics of process components, which increases the flexibility of the overall process.
