TEPET
The Techno Economic Process Evaluation Tool (TEPET), developed at the Institute of Engineering Thermodynamics by the group Techno-Economic Analysis (TEA), enables an automated technical, economic as well as ecological process analyses. For this purpose, the processes are simulated in Aspen Plus®. The resulting material and energy flows and information on the process units are extracted from the process simulation. Automated sensitivity analyses can be realised by changing parameter/variables in the simulation through TEPET. As a result, this allows to automatically calculate for example the capital and operational expenditures, the net production cost and environmental impacts like the global warming potential.
Research goals
https://doi.org/10.1016/j.enconman.2021.114651TEPET allows to investigate processes from a technical (material and energy efficiencies), economic (net production cost, capital investment and operational cost) and ecological (e.g. global warming potential) perspective. A particular research focus is on processes for the production of alternative fuels (Fischer-Tropsch fuel, methane, methanol, ammonia, …) from electricity and/or biomass. Therein, the work targets to conduct in-depth process analyses (e.g. to identify and quantify cost and environmental impact drivers) as well as to improve the processes (e.g. efficiency increase through heat integration or optimal operating conditions of certain process units).
