Batch distillation in a column with a middle vessel can avoid many of the disadvantages associated with the regular batch distillation processes. In this paper we present an experimental investigation of the separation of a zeotropic ternary mixture via total reflux operation and of the separation of an azeotropic binary mixture via batchwise extractive distillation. Moreover, the results obtai...
for the gas stream in the distillation unit. Coagulation of the beer samples, especially when running a large number of samples, can arise in the distillation unit. Coagulation interferes with the smooth flow of sample through the distillation unit and gives erratic results. Coagulation was prevented by mixing the sample with a M potassium hydroxide solution (Figure 2) before pumping it into th...
the yield performance of 23 barley (hordeum vulgare l.) genotypes in sixteen test environments across a barley growing region of china was evaluated. the experiment was conducted using a randomized complete block design with three replicates, in two cropping seasons (2010-2011, in the south; 2012-2013, in the north). the gge biplot was applied to analyze the data obtained in the multi-environme...
This paper presents a new strategy for synthesizing an appropriate process with multi-objective under uncertainty. The uncertainty is classified depending on its sources and mathematical model structure as deterministic or stochastic. The proposed methodology is a two-layer algorithm. In the outer layer, the synthesis problem is represented by a multi-objective optimization problem considering ...
Multi-effect distillation (MED) systems are considered to be the most energy-efficient thermal desalination methods. This paper introduces development of a novel system for performance superior MED same operating temperature limits. Such an unprecedented achievement was attained by upgrading heat source using chemical potential adsorption phenomena. The proposed Adsorption Heat Transformer (AHT...
Vapour recompression system has been used to enhance reduction in energy consumption and improvement in energy effectiveness of distillation columns. However, the effects of certain parameters have not been taken into consideration. One of such parameters is the column heat loss which has either been assumed to be a certain percent of reboiler heat transfer or negligible. The purpose of this st...
