Problem 13-9
The double block and bleed system shown in Figure 13-2 is an excellent
design feature that is often added to all monomer lines. However, it has one
problem; i.e. it creates another tank with a hazardous monomer. Develop a
new design of the double block and bleed system that is inherently safer than
the one shown in Figure 13-2.
Solution 13-9
As illustrated below, the bleed line and tank can be replaced with a source of
nitrogen. The nitrogen is added when the double block valves are closed.
