Abstract: A computing system can include a radio transceiver and tracking manager software for tracking the location of objects such as tools. Radio frequency identification tags are attached to the objects and can communicate with the radio transceiver. During an initial registration process, the tracking manager software sends an initial registration signal to each object so that the object can be identified in a registered objects file. In one instance, the tracking manager software subsequently sends periodic interrogation signals to the objects to confirm that the objects are within a certain proximity. In another instance, after completing a task a worker can check-in each object wherein the tracking manager software sends interrogation signals to the objects to confirm that all of the objects are accounted for.

Abstract: A process for shutting down a hydroprocessing reactor and for removing catalyst from the reactor, wherein the reactor includes a quench gas distribution system. The process comprises shutting off hydrocarbon feed to the reactor, stripping hydrocarbons from the catalyst, and cooling the reactor to a first threshold reactor temperature in the range of from 375-425° F. (190-218° C.). At least a portion of circulating gaseous medium flowing to the reactor is then routed through a temporary heat exchanger and cooling the gas to not less than 40° F. (4° C.). Once cooled, mixing the cooled gas with the circulating gaseous medium flowing to the reactor. Continuing steps routing and cooling until a second threshold temperature is reached wherein the reactor temperature is in a range between 120° F. and 250° F. (49° C.-121° C.). The reactor can then be purged with N2 gas, followed by introducing water into the reactor via the quench gas distribution system. The catalyst can then be safely removed from the reactor.
