The dominant synthetic route is cumene oxidation, which accounts f PLANT DESIGN FOR PRODUCTION OF PHENOL 9 for about 95% of the total phenol production. Separation is done by a sequence of distillation units and phenol and acetone are obtained as pure products. Based on the three dimensions of FEE, a systematic lifecycle design process model is proposed, which consists of: the three FEE requirements; two design objects (physical structure and lifecycle structure); and, the FEE evaluation streams of LCQ (functional lifecycle quality), LCA (environmental lifecycle assessment) and LCC (economic lifecycle costing). A neural network approach is developed to predict an approximate LCA of grouping products in conceptual design. The design of the phenol production process is developed as part of the MSc-level course on Process Design at DTU. A 5% solution (by mass) of cane sugar in water has freezing point of 271 K. Calculate the freezing point of 5% glucose in water if Today, the cumene is used almost exclusively for manufacturing phenol and acetone. The targeted improvements are related to reduced energy consumption through better heat integration and process optimization, which results in identifying the more sustainable design in terms of raw materials usage, energy consumption, water consumption and environmental impact. The proposed approach does not replace full LCA but it provides some useful guidelines for the design of environmentally conscious products in the conceptual design phase. Both the lack of detailed information and time for a full LCA for a various range of design concepts demonstrate the need for a new approach to environmental analysis. As the base case design, auto-catalyzed oxidation of cumene to cumene hydroperoxide subsequently cleaved over a solid catalyst to phenol and acetone is selected. The process design work is divided into 12 sequential tasks that comprise all stages of conceptual design, starting from the consideration of qualitative aspects of the process flowsheet and preliminary calculations to detailed process simulations, equipment sizing, costing, economic evaluation, sustainability and LCA/sustainability assessment of the designed process.
