Abstract: A monitoring system is configured to monitor an environment within an enclosure of a heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system. The monitoring system includes a sensor configured to acquire data indicative of an environmental parameter value within the enclosure. The monitoring system also includes a controller configured to receive the data from the sensor, to determine occurrence of a thermal event within the enclosure based on the data, and to instruct a circuit breaker of the HVAC&R system to transition to a fault configuration in response to determining the occurrence of the thermal event.

Abstract: A low pressure swing adsorption process and apparatus for the recovery of carbon dioxide from multi-component gas mixtures, utilizing the simultaneous purge and evacuation of opposite ends of the adsorber(s) to effect controlled depressurization in the adsorber bed(s) to maintain the constant purity of a carbon dioxide-enriched product stream recovered from the adsorber inlet(s).

Abstract: The invention comprises a PSA apparatus for the separation of a heavy component from a light component in a feed stream. The apparatus includes an adsorbent bed comprising either a mixture of adsorbents or composite adsorbent particles wherein each particle comprises two or more adsorbents. At least one of the adsorbents is comparatively weak and the other is comparatively strong. Another embodiment of the invention is a PSA prepurifier having a bed of adsorbent material which comprises a mixture of, or composite adsorbent particles wherein each particle comprises at least two adsorbents, at least one of the adsorbents being comparatively strong and at least another of the adsorbents being comparatively weak.
