Energy-Saving Potential of an Existing Monomer Production by Combined Process and Inter-Plant Integration

The problem of efficient use of energy is crucial for the industry as it affects final revenue and environmental issues. Petrochemical sites have extensive utility networks that are consuming and distributing energy to processes. This paper proposes the approach for analysing an interplant integration with the use of intermediate utilities applying individual (Tmin for all utilities. It was performed by the use of real temperature when plotting Total Site profiles, optimising the temperature of intermediate utility and rearranging remaining utility demands with existing utility. The case study analysed monomer production at the petrochemical site and assessed the potential for utility reduction by improving the existing process to process recovery and interplant integration. The cooling capacity reduction is 31 % and heating demands were reduced by 80 %. The additional option for power generation was considered.
