WebThermal runaway reactions were involved in the Bhopal disaster of 1984, in which methyl isocyanate was vented from a storage tank of the liquid, and oc- cur in liquid peroxide explosions, yet to date there have been few investigations into the mechanism of thermal runaway in such liquid thermoreactive systems. Webdesigned. (For exothermic runaway, an increase in relief pressure also increases the relief temperature and, hence, the rate of pressure generation, so that a larger vent is needed). …

WebDuring venting of a runaway chemical reactor, the volume of the reactor contents rises or swells with the volume of gas and/or vapour bubbles formed within the liquid. The ability to model level swell is essential in order to determine how much liquid the disposal system must be designed to handle. WebMay 4, 2010 · Summary.

The lower part of the reactor was propelled off of its supports onto the building floor. The reactor agitator landed on the roof, and the top of the reactor was found about 500 ft(150 m) away. Fortunately, nobody was injured.
WebThermal runawaydescribes a process that is accelerated by increased temperature, in turn releasing energythat further increases temperature. Thermal runaway occurs in situations where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result.
