WebA typical runaway scenario involves reactants being charged into a reactor at room temperature and heated with stirring until the reaction temperature is reached. … WebUncontrolled, or runaway, reactions can occur as a result of various situations, such as mischarged raw materials, failure of a reactor's cooling system or the presence of contaminants. If the heat generation exceeds the reactor's ability to remove it, the reaction can accelerate - or run away - and cause the temperature and pressure to increase.

WebThe reaction occurs as liquid hydrocarbon contacts a fixed bed of catalyst with excess hydrogen at a high pressure. During normal operation, adding a cold hydrogen quench to sweep away the heat of reaction to the downstream heat exchangers controls temperature. In an emergency situation depressuring the reactor can stop the reaction.
