  • Monitoring and profiling conditions in an enclosed vessel provides useful information for understanding reaction kinetics, catalyst performance, safety parameters, and system efficiency, among others. This information is particularly useful when the environment within the enclosed vessel is extreme or harsh.

To avoid undesirable process conditions that may impact system performance under these extreme/harsh environments, sensors are used to monitor parameters such as pressure and temperature and provide insight as to the conditions within the enclosed vessel.
