WebFouling of a reactor zone is partially overcome by a periodic increase of the reactor pressure by means of the operation of a control valve located near the reactor exit. The periodic operation of the valve results in an increase of the velocity of the reaction mixture that tears away the polymeric deposits. Fouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms (biofouling) or a non-living substance (inorganic or organic). Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined and useful function and that the fouling …
