Patent ID: 8280554

Claim:
A system for preventing an equipment failure from a potentially catastrophic exothermic reaction in a gas purifier bed, comprising: providing one or more dual temperature sensors at various locations in the purifier bed having one or more inlet and outlet valves and, wherein a first set of temperature measuring devices are disposed in close proximity to a corresponding second set of temperature measuring devices forming part of each individual dual temperature sensor; selecting a first predetermined temperature differential between a first and second temperature measuring device for each individual dual temperature sensor; selecting a second predetermined temperature; preventing failure by shutting down the gas purification bed upon determining that the differential between the first and the second temperature measuring device in each of the dual temperature sensors is below the first predetermined temperature differential but wherein the first and the second temperature measuring device of any of said dual temperature sensors exceeds the second predetermined temperature, thereby closing the inlet and the outlet valves to isolate the bed.
