Abstract

A METHOD FOR CONTINUOUSLY STRIPPING AN UNREACTED MONOMER FROM A VINYL CHLORIDE PASTE RESIN LATEX, COMPRISING THE STEPS OF CONTINUOUSLY SUPPLYING THE LATEX TO A VACUUM RECOVERY VESSEL (1), WHEREIN THE LATEX IS BOILING WITH GENERATION OF FOAM, UNDER THE CONDITION THAT THE TEMPERATURE OF THE LATEX TO BE SUPPLIED IS HIGHER THAN THAT OF THE LATEX IN THE RECOVERY VESSEL, WITHDRAWING A MONOMER GAS GENERATED IN THE RECOVERY VESSEL THROUGH AN EXHAUST LINE PROVIDED WITH A FOAM SEPARATOR (2), CONTACTING THE FOAM ENTRAINED INTO EXHAUST LINE (5) WITH STEAM INTRODUCED TO THE EXHAUST LINE AND/ OR THE FOAM SEPARATOR (2), THEREBY DESTROYING THE FOAM, AND RETURNING THE RESULTING LATEX IN THE SEPARATOR TO THE RECOVERY VESSEL (1). THE UNCREATED MONOMER CAN BE EFFICIENTLY RECOVERED FROM THE LATEX BY CONTINUOUS OPERATION, AND DEFOAMING CAN BE ACHIEVED WITHOUT DETERIORATING THE QUALITY AND WITHOUT LOWERING THE PRODUCTIVITY.(FIGURE 1)
