Abstract (EN): This work addresses the application of a detailed Pinch Analysis modelling technique, developed in Excel/VBA, for a multipurpose refinery batch plant. This application is focused on developing a tool that enables a quick analysis of Heat Integration to improve the energy-efficiency by rescheduling the operations. The developed tool was used with a real case study process data of a vegetable oil's refining plant. Several scenarios of re-scheduling were used to still accomplish the demand from the downstream plant production. This study show that a reduction of about 15 % in both utilities consumption can be achieved by some scenarios compared to the current vegetable refining scheduling. Also the results show that the integrated approach leads to better synchronization between production plant and the utility system. Thereby, the integrated approach leads to significant reduction in energy costs and gas emissions, showing advantages for future improvements based on rescheduling and indirect/direct heat exchange opportunities. Also the results of this work indicate a great potential of the use of HENs in real Batch Process systems for refining vegetable oils and present an important enhancement on the industrial plant thermal energy efficiency.
