It also encapsulates guidelines, challenges and opportunities to enhance profitability by reducing power consumption in high energetic-intensive chemical processes. For this purpose the application of heat pumps, vapor recompression, optimal design of heat exchanger network and self-heat recovery technology have been put into effect. Furthermore, with the fluctuation of oil prices in countries where economic energy sources are unavailable, this investigation provides a useful frame for critical decision making to minimize points of conflict between energy goals, production and revenue.Table of Contents Index of Tables xi List of Figures xii Chapter 1.
