| Popis: |
The heat exchanger network (HEN) of the unit of benzene production at petrochemical plant was inspected and the obtained data were analyzed for possible plant retrofit targeting the minimal energy consumption and increasing of plant efficiency. The benzene-toluene-xylene fractionation, hydrogenation, hydrodesulphurization and hydrothermo processing units of the plant were analysed and the data of existing HEN flowsheets were extracted. The minimum temperature difference for the retrofit was determined by analyzing the cost parameters of the proposed modifications as well as the energy cost. Using Pinch Analysis methodology the Composite Curves and Grid Diagram were obtained for the integrated processes of these plant units. The new flowsheet of the HEN of the regarded units was developed; and the possible application of heat transfer equipment was analyzed and proposed. |
