Ethanol distillation: the fundamentals
Certain fundamental principles are common to all distilling systems. Modern distillation systems are multi-stage, continuous, countercurrent, vapor-liquid contacting systems that operate within the physical laws that state that different materials boil at different temperatures. Represented in Figure 1 is a typical distillation tower that could be employed to separate an ideal mixture. Such a s...
متن کاملRegimes of extractive distillation in ethanol production
The influence of operating conditions to the effectiveness of extractive distillation process was investigated by using the method of gas chromatography. The experiment took place on an industrial vacuum plant of purification ethanol from impurities formed during fermentation. It is obtained that the concentration of different micro impurities at the selection zones depends on the temperature a...

متن کاملIXIR: A statistical information distillation system
The task of information distillation is to extract snippets from massive multilingual audio and textual document sources that are relevant for a given templated query. We present an approach that focuses on the sentence extraction phase of the distillation process. It selects document sentences with respect to their relevance to a query via statistical classification with support vector machine...
