Improved Safer Fittings for a Process Reactor

1 It Is Difficult and Dangerous to Remove the Accumulated Pasty Sludge 

It is difficult and dangerous to remove the accumulated pasty sludge from the choked bottom nozzle of the reactor by simply opening the drain valve and inserting a rod from below. The sludge may suddenly come out and splash on the 

The wide angle observation nozzle shown at the right allows a good view of reactor internals such as agitator, baffles, and movement of reaction mass. This is not possible with a narrow angle view nozzle shown at left (Fig. 6.8). 

6 Pressurised Cooling System for Shell and Tube Cooler 

This system can be dangerous if water enters the hot fluid side in case of a tube leak and reacts with it. If the water flow is under siphon, the hot fluid will enter water side and wiU come out from the open end (Fig. 6.9).
