Abstract

An apparatus comprising a processing unit; a feed conduit and an effluent conduit connected to the processing unit; at least one operating parameter device associated with the processing unit, the feed conduit, the effluent conduit or a combination thereof; a catalytic alloy hydrogen sensor in fluid communication with the processing unit, the feed conduit, the effluent conduit or a combination thereof; and a computer processor electrically connected to the catalytic alloy hydrogen sensor, has been developed. A pressure indicator may be positioned to indicate the pressure of fluid passing through the catalytic alloy hydrogen sensor and there may be an electrical connection between the computer processor and the pressure indicator. The catalytic alloy hydrogen sensor may be a palladium-nickel catalytic alloy hydrogen sensor.
