Traditional solvent recovery in the extraction step of edible oil processing is distillation,which consumes large amounts of *** the distillation is replaced by membrane process,the energy consumption can be reduced *** this work,two kinds of membrane,PDMS(polydimethylsiloxane) composite membrane and Zeolite filled PDMS membrane were prepared,in which asymmetric microporous PVDF(polyvinylidenefluoride) membrane prepared with phase inversion method was functioned as the microporous supporting layer in the flat-plate composite *** different function compositions of the PDMS/PVDF composite membranes were characterized by reflection Fourier transform infrared(FTIR) *** surface and section of PDMS/PVDF composite membranes were investigated by scanning electron microscope(SEM).The PDMS NF(nanofiltration) membranes were then applied in the recovery of hexane from soybean oil/hexane miscellas(1:3,mass ratio).The effects of pressure(0.5-1.5 MPa),cross-linking temperature and PDMS layer thickness on membrane performances were *** results indicated that both two kinds of NF membranes were promising for solvent recovery,and zeolite filled in PDMS NF membrane could enhance the separation performance.

Increasing demand to practice more sustainable processing has led to renewed interest in the area of solvent recovery within the pharmaceutical *** has been the conventional unit operation of choice,and though generating high purity solvent,distillation can be energy-intensive and a low energy alternative is desirable.A potential alternative has been identified in the emerging separation technique of organic solvent nanofiltration （OSN）.The work presented here demonstrates that OSN can be used effectively to recover solvent within the solvent specification while using less than 20 times the energy required for an equivalent distillation *** added benefit of using the athermal OSN approach can also be seen in that valuable solutes,such as active pharmaceutical ingredients （API）,can be recovered.

Fabrication of cost effective iron ore slime ceramic membrane for the recovery of organic solvent used in coke production

引用

International Journal of Coal Science & Technology 2016年第2期3卷 226-234页

Improvement of coking properties of sub-bituminous coal （A） and bituminous coal （B） was done using blended organic solvents, namely, n-methyl-2-pyrrolidinone （NMP） and ethylenediamine （EDA）. Various solvent blends were employed for the coal extraction under the total reflux condition. A low-cost ceramic membrane was fabricated using industrial waste iron ore slime of M/s TATA steel R＆D, Jamshedpur （India） to separate out the dissolved coking fraction from the solvent-coal mixture. Membrane separations were carried out in a batch cell, and around 75 % recovered NMP was reused. The fractionated coal properties were determined using proximate and ultimate analyses. In the case of bituminous coal, the ash and sulfur contents were decreased by 99.3 % and 79.2 %, respectively, whereas, the carbon content was increased by 23.9 % in the separated coal fraction. Three different cleaning agents, namely deionized water, sodium dodecyl sulphate and NMP were used to regain the original membrane permeability for the reusing.

Design and Operation of Batch Extractive Distillation with Two Reboilers

引用

Chinese Journal of Chemical Engineering 2007年第2期15卷 286-290页

作者：华超李鑫钢徐世民白鹏 School of Chemical Engineering and Technology Tianjin University

This paper proposes a modified operation mode of batch extractive distillation with two reboilers. The seoaration of ethanol and water using as ethylene glycol is well done to validate the feasibility, of this mode. The pilot-plant experimental data under the identical operational conditions between the regular mode and the modified mode are in particular discussed. The studied results prove more practical advantages of *** mode over the regular mode such as easier operation control, more flexibility and higher separation efficiency etc. So it suppues certain guidance for the industrial application of batch extractive distillation process.
