Phthalic Anhydride Production

This book is to innovate process and design and study the economic feasibility for production of Phthalic Anhydride plant.In this book,o-xylene chosen as raw material of the plant which contains mainly of reactor,vapor liquid separator then two distillations columns. A material and energy was made for the process to determine the total energy and flow in the process,both calculations was compared with HYSYS simulations results.A heat integration is applied for process to reduce energy costs(heating and cooling utilities) and losses. In addition, a detailed equipment design was conducted for the all major equipment to find the sizes and required number of items.Designs were made for all the ancillary equipment after heat integration(heat exchanges,fired heaters storage tanks,pump and compressor). After that, the basic safety requirements were determined and a hazard analysis was conducted, a simple layout was also created. A basic control scheme was developed for the overall process,to ensure that the produces meet the requirements.
