This paper presents a case study on improving the energy integration of a gasbased ethylene process by focusing on major sources of thermal exergy losses.Exergy analysis is used to find the main sources of thermal exergetic inefficiency. Thermal solutions are then developed, leading to a comprehensive list of cold and hot process streams that could potentially reduce exergy losses from these sources. Pinch analysis is then carried out to screen these streams so only those, which can minimize the energy requirement, are maintained.Besides this, pinch analysis is used to select utilities and to explore cogeneration potential. Thus, the methodology used in this paper takes advantage of both exergy and pinch analyses, in a way that all the possible thermal solutions supported by exergy analysis are considered, preventing exclusion of any hot or cold process stream with high potential for heat integration during pinch analysis.

“…The authors demonstrated practical limits such as steam mains superheat and turbine exhaust dryness and improved the accuracy of the targeting, and overcome the shortcomings of previous targets. The combination of different methods was used for utilities pre-design in [18]. The authors proposed a preselection algorithm for utilities, focused on chillers, heat pumps, Organic Rankine Cycles (ORC) units and Combined Heat and Power (CHP) units.…”

Appropriate integration of geothermal energy sources by Pinch approach: Case study of Croatia

et al. 2016

Geothermal energy is a widely available renewable energy source. In Croatia geological data has been indicating promising potential, especially in the NorthEastern part of the country with a geothermal gradient higher than 49°C/Km and terrestrial heat flux of 76 mW/m 2. Nonetheless, despite this potential, this resource is not highly exploited to date. Efficient use of geothermal energy can contribute on reducing Croatia's energy dependence. In this paper, a methodology of a possible integration of geothermal energy within residential, commercial and industrial systems was attempted. Pinch analysis was used to find the best ways to fulfil the energy system requirements in an efficient, clean and cost-effective way. The used approach gives a good overall picture of energy targets for process, site and utility levels. The recommendation for cost-effective integration of geothermal energy into regional energy network is considered by use of Pinch Analysis. Additional attention was paid to geothermal energy utilization in low enthalpy sedimentary environments. The obtained results can be used for integration of geothermal energy in different cases and "countries". It gives general recommendation for geothermal sources placement as well as for energy planning and regional sustainability.
