Method and apparatus for minimizing accumulation of polymer on process equipment, especially safety devices

An apparatus for minimizing accumulation of polymerizable material on equipment affixed to said apparatus during use of said apparatus to operate a process comprising polymerizable material and at least one process fluid comprising moving liquid phase fluid, said apparatus comprising:

• (a) a process vessel having at least one wall forming an interior space for retaining the at least one process fluid therein, and during operation of the process, said interior space comprises at least one wetted region comprising said moving liquid phase fluid;
• (b) equipment affixed to said wall of said process, in fluid communication with said interior space, and positioned proximate to said wetted region such that, during operation of the process, said moving liquid phase fluid is at least intermittently in contact with said equipment such that one or more of accumulated polymerizable material, condensate comprising same, and polymer, is washed off of said equipment.
