Stack scrubber reactor

Many emergency relief vents are therefore connected to a disposal system which may include knock-out dmms. quench tanks, flare stacks and scrubbers. The size and capacity of such systems needs to be checked once the relief area has been calculated, particularly where a new reaction is being sited in an existing reactor unit. In addition, consideration has to be given to the possibility of the reaction continuing in the disposal system. 

Pressure relief equipment includes relief valves, safety valves, rupture discs, piping, drums, vent stacks, pressure indicators, pressure alarms, pressure control loops, and flare systems. Pressure relief devices can be placed on pumps, compressors, tanks, piping, reactors, distillation columns, refrigeration systems, and many other kinds of equipment. Materials that cannot be released to the atmosphere are recycled back to the system, or sent to a scrubber or flare system. The discharge from pressure relief equipment is collected in a closed piping system and sent to a flare stack. Harmless gases are discharged at a safe distance from plant operations areas.
