The use of pinch analysis technology to assess the energy efficiency of oil refining technologies
Exergy pinch-analysis of the heat exchange system of the furnace of the primary oil refining unit is carried out. Composite curves are created using a mathematical model, and then the optimal structure of the heat exchange with minimal exergy losses is constructed. Exergy pinch analysis allows revealing the magnitude and location of exergy losses. In the heat exchange system of the furnace exergy loss is 9 MW. It is possible to increase the efficiency of the furnace by 18.5%. An additional heat exchanger connecting it to the oil stream is introduced for rational use of residual exergy.
