Applying temperature-activated relief devices

Follow these system design and installation guidelines

Gollin, M., Carmagen Engineering, Inc.

Conventional, spring-activated pressure relief valve systems may not be effective for some types of exothermic reactions. The use of temperature-activated relief valves is discussed in detail. In this application, relief valves are opened and closed automatically at defined temperatures. This allows for control of the process variable (i.e., temperature) which most directly affects the reaction rate and, in turn, controls the rate of pressure increase. The design characteristics and requirements for the components of a temperature-activated relief valve system are presented, together with the factors that should be considered when analyzing the dynamic behavior of the process. Finally,
