Abstract:
Accumulation of polymer on equipment, which is in contact with polymerizable material during normal process operation, is minimized by the method and apparatus of the present invention. The method involves positioning and affixing the equipment, such as a pressure relief device, to process apparatus, such as a distillation column, proximate to a wetted region formed by liquid phase fluid in the process apparatus, such that the moving liquid phase fluid is at least intermittently in contact with the equipment and one or more of accumulated polymerizable material, condensate including same, and polymer, is washed off of the equipment. The apparatus of the present invention is effective for maintaining the service-readiness of the equipment, which provides for safe long-term operation of the process apparatus.
