Question:

Decide which types of relief devices and configuration should be used for the following situations. Explain.

a. The process fluid is highly toxic.

b. The process operates close to the MAWP of the vessel.

c. The process fluid tends to polymerize and plug.

d. A very large relief is required.

e. Two relief scenarios are identified: runaway reaction requiring a very large relief and a relief for more routine and much lowerpressure excursions.

f. The process has regular and large pressure cycles.

g. The fluid in the process contains liquid with small-diameter solid particles.

h. The process and vessel operate at very high pressures.

i. A high-pressure scenario occurs very quickly.

\(\mathrm{j}\). The process is at a high temperature.

\(\mathrm{k}\). The relief discharges into a header with pressure fluctuations due to other activities elsewhere in the plant.

1. The relief must discharge a high volume of fluid.
