Influence of initial binary mixture state of matter on heat costs at rectification

Тонкие химические технологии, 2014
Analysis of heat cost for rectification was performed taking into account the phase state of the original mixture. It was proved theoretically that increasing feed vapor fraction leads to decreasing energy consumption in conventional distillation process.

Management rectification column close to the optimal

Башкирский химический журнал, 2011
We solve the problem of robust control rectification column close to the optimal mathematical model which can be affected by parametric and external uncontrollable disturbances. The problem is solved by the introduction of the auxiliary circuit a specially structure, which allowed, how to select the uncertainty acting on the object management and ...

Simulation and Analysis of the Cascade Process for ¹³⁶Xe Isotope Separation Based on Microchannel Distillation Technology

Zhileng xuebao
Conventional distillation methods face significant challenges in xenon isotope separation. This paper proposes a cascaded distillation system based on a microchannel distillation （MCD） apparatus for 136Xe enrichment. The relative volatilities， saturation
