5th International Conference EnRe - Energy & Responsibility : book of extended abstracts
2022, proceedings

Abstract: The tendency to improve energy devices, the impact of environmental factors and the development of new technologies for the exploitation of sustainable resources contribute to the fact that we have witnessed intensive energy development in the last decade. The two most important Slovenian energy pools, located in Velenje and Krško, are at the turning point of renovation, and are facing major challenges in the design and planning of modern energy devices. The current generation faces a great ethical responsibility to leave their descendants a world with as little human impact on the environment as possible. Therefore, communication between experts and researchers, discussion and exchange of different views for the future is of the utmost importance, which is exactly the purpose of the EnRe Conference.
Keywords: renewable energy and energy storage systems, classic energy systems, policies and strategies for RES, alternative energy systems, energy conversions, energy transfer, electrical machine, thermal machines, mathematical methods in energy engineering, environmental protection, micro and nano energetics, hydrogen technologies, low carbon technologies and strategies, nuclear energy, smart buildings, smart cities and smart grids

Process integration of a steam turbine
Andreja Goršek, Peter Glavič, 2003, original scientific article

Abstract: Cogeneration consists of combined production of electricity and heat using only one fuel which allows remarkable energy savings in comparison with a system producing electricity and heat separately. The possibilities for integrating a cogeneration system with chemical processes has been studied in this paper. Improvement in the systems where high temperature streams exist can be achieved by direct integration of steam turbine with them. Hot reactor utility was used instead of fuel to produce electricity and steam for further process heat requirements. A thermodinamics oriented approach to identify and preliminary design a cogeneration plant that completely satisfies process heat and power demand is highlighted. Pinch analysis with extended grand composite curve enables rational choice of utilities. The acrylic acid process was used to illustrate the procedure proposed. Economic attractiveness based on payback time and net present worth indicated that the steam turbine based cogeneration system would yield return period of less than 3 months, showing that the investment in cogeneration could be of interest for this plant.
Keywords: process energetics, efficient energy use, process industry, cogeneration systems, acrylic acid, technological processes
