摘要： A process for feeding a slurry of thermoplastic synthetic polymer particles such as polyethylene terephthalate homopolymers and copolymers in combination with a liquid such as water at a liquid temperature greater than the normal boiling point of the liquid, under a pressure greater than the vapor pressure of the liquid at the liquid temperature, into a separation zone such as a centrifugal dryer, and within the separation zone: a. separating the liquid from the particles, and b. drying the particles; while under a high pressure equal to or greater than the vapor pressure of the liquid. There is also provided a process for decoupling the dried particles from the separation zone to an atmosphere having a pressure less than the vapor pressure of the liquid while maintaining the vapor pressure of the particles prior to decoupling equal to or above the vapor pressure of the liquid at the liquid temperature.

摘要： A process and apparatus which reduces the fines in a liquid discharge stream and/or increases the dryness of a solids discharge stream while under a pressure equal to or greater than the vapor pressure of the liquid. There is provided a process for separating particles such as polyethylene terephthalate or polyethylene naphthalate from a liquid in a slurry comprising: a. feeding a slurry comprising solid particles and a liquid into a within a separation zone maintained at a pressure equal to or greater than the vapor pressure of the liquid; b. contacting the slurry in the separation zone with a porous filter, optionally a microfilter, nanofilter, reverse osmosis filter, or ultrafilter, and separating liquid from the particles, wherein the liquid flows through the filter into an outer annulus defined as a space between the wall of the separation device and the filter, and said porous filter optionally having a terminal point beyond which the separated liquid does not pass from the outer annulus back through the filter; c. accumulating no liquid in the outer annulus or accumulating liquid in the outer annulus at a level below or in front of the terminal point, and continuously discharging the separated liquid from the outer annulus through a liquid outlet; d. decoupling the particles from the separation zone through the solids outlet to a low pressure below the vapor pressure of the liquid at the liquid temperature within the separation zone while maintaining a pressure on the particles prior to decoupling at or above the vapor pressure of the liquid within the separation zone.
