    Title: REDUCING ENERGY REQUIREMENT IN LATEX CONCENTRATION BY ULTRAFILTRATION
    Authors: SHEN, JJS;MIR, L
    教師: 沈君山
    Date: 1982
    Publisher: American Chemical Society
    Relation: INDUSTRIAL & ENGINEERING CHEMISTRY PRODUCT RESEARCH AND DEVELOPMENT, American Chemical Society, Volume 21, Issue 1, 1982, Pages 63-68
    Keywords: LATEX CONCENTRATION
    ULTRAFILTRATION
    Abstract: This paper discusses the industrial application of ultrafiltration technology for removing water from both the in-process and waste latex streams. Due to the high level of permeate flux attainable with stable latices, the + ultrafiltration process for latex concentration is becoming economical and practical on the commercial production scale. Recent process and product developments for latex ultrafiltration are presented, with particular reference to using tubular + ultrafiltration membranes. Several technical parameters of interest such as flux characteristics, concentration polarization, latex stability, and membrane cleaning are discussed. Performance data with PVC and SBR latices collected in laboratory and + pilot plant studies are presented. Finally, a comparison of operating energy costs among ultrafiltration and evaporative methods for PVC latex dewatering are tabulated. It is shown that the energy cost for the ultrafiltration process is only a fraction + of that for the more energy-intensive thermal evalporation processes.
