| 20110150711 | Loop Reactor for Emulsion Polymerisation - A polymerization reactor comprising a circulation loop, an inlet for raw material, an outlet, driving means for circulating a reactor charge within the circulation loop, and a pig station for storing, launching, and receiving cleaning pigs. The pig station comprises a lid to cover an opening enabling removal of the cleaning pig. The pig station is constructed as a box with a cylindrical bore connected at both ends to the circulation loop, the bore having a central part with a diameter which is larger than the inner diameter of the circulation loop. At a transitional part at the outer ends of the bore the bore diameter narrows down to be substantially equal to the inner tube diameter of the circulation loop. Over at least a part of the inner bore substantially half of the circular cross-section is formed in the removable lid. | 06-23-2011 |
