Reactor fouling
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 … 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 …

WebMay 27, 2015 · Depending on the root cause of the reactor fouling, you can use a dispersant or coagulant to manage existing organic or inorganic fouling – chemical injections can … WebFouling can create a large secondary time constant that can is particularly detrimental in the near-integrating and true integrating response of vessel temperature. For runaway reactors, the secondary time constant can cause dangerous unsafe operation from a narrowing of the window of allowable reactor temperature controller gains.
WebThere are, however, reactor designs and operations that can prevent fouling, depending on the nature of the synthesis, i.e., the particle formation mechanism and kinetics. Although … 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.
