Process optimization integrated energy

The design and optimization of energy integration schemes has been an active research area from the early days of process systems engineering. Initial efforts (Rathore et al. 1974, Sophos et al. 1978, Nishida et al. 1981) focused on the... [Pg.3]

The distillation and rectification is conducted in columns with a variable number of trays, the construction and design of which vary significantly. The setup of the distillation unit is directly linked to the quality requirements for the ethanol produced. The distillation yields a raw alcohol with an alcohol content of approximately 85-87%. The rectification is necessary to increase the alcohol content and to remove so-called fusel oils, which are C3-C5 alcohols. In modern distillation units, these two basic steps are integrated to optimize the energy requirement for the process. [Pg.135]
