DEVICE FOR CONTINUOUS CONCENTRATION butanol from dilute binary aqueous-butanol medium

摘要

The invention relates to the field of chemistry, namely the separation of fluid mixtures, and can be used in various industries, agriculture and energy. An apparatus for continuous separation and concentration of the dilute aqueous butanol-butanol medium includes stripping column to transfer fluid in the vapor phase, blower, two membrane modules installed after the second membrane module capacitor, the lower the output of which is connected with a container for collecting target butanol concentrate. Log blower connected to the output stripping column. The first membrane unit comprises a water-selective membrane polyvinyltrimethylsilane second - butanol-selective membrane of poly (4-methyl-2-pentyne) a. The scheme provides a recycle carrier gas due to the fact that the upper output capacitor submembrane space of the first membrane module and nadmembrannoe space of the second membrane module connected with the entrance to the stripping column.;The technical result - providing highly concentrated butanol extraction from dilute aqueous butanol medium. 1 yl., 2 tabl., 10 pr.
