This work presents a reactive distillation column for the catalytic disproportionation of trichlorosilane to silane which includes three consecutive reversible reactions. This reaction system is however characterized by a large distinction in the boiling points of the components, which make the reactive distillation extremely favored. Nevertheless, the normal reactive distillation column posses...

This paper presents the system adopted for the Faceted Blog Distillation task by PRIS team. The PRIS system is submitted by Pattern Recognition and Intelligent System Lab at Beijing University of Posts and Telecommunications. And a two-stage strategy is involved for this task. First, an adaptable Voting Model is carried out for blog distillation. Then, different models are designed to judge the...

Ethanol production from agro-based raw materials normally involves two major steps, fermentation and distillation. These steps are reviewed, mainly in relation to molasses, which is the most common raw material in tropical countries. The specific effect on fermentation efficiency of molasses quality in terms Fermentable Sugars, the ratio of fermentable to non-fermentable solids, Volatile Acids,...

This paper presents steam temperature models for steam distillation pilot-scale (SDPS) by comparing Pseudo Random Binary Sequence (PRBS) versus Multi-Sine (M-Sine) perturbation signal Both perturbation signals were applied to nonlinear steam distillation system to study the capability of these input signals in exciting nonlinearity of system dynamics. In this work, both linear and nonlinear ARX...

ABSTRACT-This paper proposed a control scheme based on fuzzy logic for a methanol water system of bubble cap distillation column. Fuzzy rule base and Inference System of fuzzy (FIS) is planned to regulate the reflux ratio (manipulated variable) to obtain the preferred product composition (methanol) for a distillation column. Comparisons are made with conventional controller and the results conf...

1,3-butadiene, bd is produced from c4-cut by extractive distillation. the separation of 1,3-butadiene from c4-cut is not possible through the conventional distillation processes, because several mixtures have consisted of close boiling points constituents and make azeotrope. the basf extraction distillation process in bd unit of jam and amirkabir petrochemical company improves the relative vola...

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...

Methyl propionate, also known as methyl propanoate, is a clear colourless liquid with a characteristic odour (fruity smell and taste). In this study, the formation of methyl propionate through the esterification of propionic acid and methanol was investigated in the reactive distillation system using a conventional (CBD), single feed (SF-SBD), and double feed semi-batch distillation (DF-SBD) co...

Hybrid separation systems have recently been hailed as one of the inost promising alternatives to conventional capital and energy intensive separation processes. Hybrid separation systems are able to effectively separate inixtures commonly encountered in the fine chemical and pharmaceutical industries that are difficult or impossible to separate by conventional distillation processes due to aze...

When a quantum cryptographic system operates in the presence of background noise, security of the key can be recovered by a procedure called key distillation. A key-distillation scheme effective against so-called individual (bitwise-independent) eavesdropping attacks involves sacrifice of some of the data through privacy amplification. We derive the amount of data sacrifice sufficient to defend...
