Energy consumption of equipressure and various pressures technical alcohol distillation
 Audy, Dan ; Leštinský, Pavel (referee) ; Smejkal, Quido (advisor)
This hork compares the heat consumption of two units for the production of technical alcohol. The aim is to compare ordinary arrangement of rectifying distillery with an alternative arrangement, based on a modified pressure device profile. The first unit is based on the classic arrangement brewhouse, working at atmospheric pressure. The alternative unit works with different pressures in columns. In this case, the pressures are chosen so that it was possible to use heat from the head of overpressure rectification column for reboiler of vacuum mash column. The principle of pressure differences between the two columns and appropriate choice for this difference also allows the beneficial use of surplus heat. It also reduces the risk of clinkering incrusts in reboiler mash column because this works at lower temperatures than the mash column atmospheric embodiment. The comparisons of the media in this work are: The amount of steam used for reboilers of both columns, the amount of cooling water used for condensation and cooling of process streams. Furthermore, an approximate estimate of electricity consumption for pumps and other machinery. For both units is considered the same amount of mash and the same amount of product of comparable quality. The product was a technical alcohol 96.4% aa at a temperature of 25 ° C.
