Publication number: 20040108077Abstract: The present invention provides a contactor apparatus and method for removing solvent from a polymer cement. The resulting polymer is substantially free of solvent and exhibits improved porosity and more uniform particle size distribution. In one embodiment, a contactor apparatus consists of a cylindrical casing having a high pressure section, a convergence section, a high velocity section, a divergence section, and a discharge section. The polymer cement is introduced into the high pressure section to significantly and unexpectedly improve solvent removal. The convergence and divergence sections preferably have cross-sectional areas that correspond to an effective angle from about 4° to about 65°. The polymer cement is mixed with high pressure steam. After converging, the polymer cement forms more uniform droplets due to high shear of steam. In the divergence and discharge sections, the polymer is substantially devolatized.Type: ApplicationFiled: November 18, 2002Publication date: June 10, 2004Inventors: Joe Jerry Flores, Rong-Her Jean, Chin-Yan George Ma

Publication number: 20030205335Abstract: The present invention provides a contactor apparatus and method for removing solvent from a polymer cement. The resulting polymer is substantially free of solvent and exhibits improved oil absorption and lower fines. In one aspect, a contactor is provided comprising a cylindrical casing having a high pressure section, a convergence section, a high velocity section, a divergence section, and a discharge section. The polymer cement is introduced into the high pressure section to significantly and unexpectedly improve solvent removal. The convergence and divergence sections have cross-sectional areas that correspond to an effective angle from about 4° to about 65°, such as 6°. The polymer cement is mixed with high pressure steam. After converging, the polymer cement forms more uniform droplets due to high shear of steam. In the divergence and discharge sections, the polymer is substantially devolatized.Type: ApplicationFiled: May 2, 2002Publication date: November 6, 2003Inventors: Rong-Her Jean, Chin-Yuan George Ma
