  • Separation of ternary Heterogeneous Azeotropic Mixture of 2-ethoxy-ethanol,4-methyl-2-pentanone and water
    2011
    Co-Authors: Zhang Wei-jiang
    Abstract:

    Liquid-liquid extraction,phase separation with salt,Azeotropic distillation were investigated for the separation of ternary Heterogeneous Azeotropic Mixture of 2-ethoxy-ethanol,4-methyl-2-pentanone and water(EC+MIBK+H2O).The result shows that the results of liquid-liquid extraction were not effective;phase separation with K2CO3 as isolates has good result but a large number of salt recovery make this method too difficult to be industrialized;Azeotropic distillation with methyl isobutyl ketone as entrainer can get EC with mass fraction of 99.4% and MIBK with mass fraction of 99.2%,and has perfect future for industrialization.

  • Azeotropic distillation process of ternary Heterogeneous Azeotropic Mixture of 2-ethoxy-ethanol-4-methyl-2-pentanone-water
    2011
    Co-Authors: Zhang Wei-jiang
    Abstract:

    The ternary Heterogeneous Azeotropic Mixture of 2-ethoxy-ethanol,4-methyl-2-pentanone and water was theoretically studied by the residue curve maps(RCM),the residue curve,the distillation boundary and the liquid-liquid equilibrium curve.Through process design,simulating and experimental validation,the separation process was set up.Five steps that were used to get 4-methyl-2-pentanone with mass fraction of 99.24%,2-ethoxy-ethanol with mass fraction of 99.17%,and water with mass fraction of 98.52% were designed,including Azeotropic distillation,phase condensed,partial reflux of oil phase,recovery of heavy components,recovery of light components.The experimental results are highly coinciding with the simulation results,which can ensure good industrial prospects of the separation process.

  • A nonequilibrium model for three-phase distillation in a packed column: modelling and experiments
    Computers & Chemical Engineering, 2004
    Co-Authors: Jens-uwe Repke, Olivier Villain, Günter Wozny
    Abstract:

    A nonequilibrium model is developed for the simulation of a three-phase distillation process in a column equipped with structured packing. The model is taking into account the mass transfer resistance between all three existing phases. Furthermore, the convective and conductive part of the heat transfer rate is calculated, which is crucial for the precision of the model. The development of the model is strongly connected with experimental investigations of a packed column. When a Heterogeneous Azeotropic Mixture is separated by distillation in a packed column, specific steady states can occur, which cannot be described by the use of an equilibrium model. The observed remarkable column behaviour is caused by the fluid dynamic situation of the two immiscible liquid phases on the structured packing surface. The simulation results are in good agreement with the experimental data of the packed column.

  • Azeotropic Distillation Process of Ternary Heterogeneous Azeotropic Mixture of Acetone,Methyl-Msopropyl-Ketone(MIPK) and Water
    2007
    Co-Authors: Ltd Northeast
    Abstract:

    Ternary Heterogeneous Azeotropic Mixture of acetone,methyl-isopropyl-ketone(MIPK) and water was studied with residue curve maps(RCM),and a decanter was set up in middle of a distillation column to fulfill the separation of acetone,MIPK and water in the column.The Heterogeneous Azeotropic distillation process was analyzed with residue curve,distillation boundary,rectifying profile and stripping profile,and liq-liq equilibrium in decanter.An energy saving distillation process was proposed based on separation process in MIPK production,and the results show that the process would not only reduce investment of equipment,but also simplify the operation,and reduce cost of production.
