Pinch technology in theory and its application to a biomass integrated gasification and humid air turbine process Garcia, B L 09 BIOMASS FUELS; 32 ENERGY CONSERVATION, CONSUMPTION, AND UTILIZATION; GASIFICATION; BIOMASS; ENERGY CONSERVATION; ENERGY RECOVERY; OPTIMIZATION; THERMODYNAMICS; ENERGY EFFICIENCY; EXPERIMENTAL DATA The Pinch Technology has become a powerful tool for the optimization of the design of heat exchanger networks during the last 20 years. In this work, the different aspects of the methodology have been studied both in a theoretical way and in a practical approach. The first part of the work is a systematic analysis of the pinch technology: what it is, how it works, what are its advantages and disadvantages. There is also a brief discussion about the pinch method and other methods which handle energy recovery problems. Once the philosophy of the pinch technology has been theoretically studied, the second part of the work is its application to two different processes. The first process analyzed is a relatively simple but realistically practical problem based on a two distillation columns system. The knowledge gained during the calculations of this process is used in the second and more complex one. This second process is an integrated biomass gasification and humid air turbine (IGHAT) which has been already optimized by a heat balance program. The application of the pinch technology to this process shows the huge potential for improvements that this technology can provide in order to save energy. All the calculations are handled by the pinch technology software program `SuperTarget`. This program is evaluated along the work. In spite of some shortcomings that have been noticed, the usefulness of the program can be claimed 26 refs, 28 figs, 7 tabs Lund Univ. (Sweden).
