Improved measurement of water content in natural gas

Garza, A., Miller, S., Endress+Hauser

Consumers likely imagine natural gas as a stream of pure methane. Those who are closer to the energy industry know that methane is the major component, but there can easily be dozens of other substances making up a sizeable portion of the total volume.

Reliability: Pushing the limit can have unexpected consequences

Bloch, Heinz P., Hydrocarbon Processing Staff

A prominent manufacturer rediscovered the old axiom, “pushing the limit can have unexpected consequences,” after experiencing many bearing failures in its 40-hp air blowers. These lifetime-lubricated (sealed) bearings had been properly installed on 20-mm shafts, and it can be assumed that premium greases were being used.

Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation

Nichols, Lee, Hydrocarbon Processing Staff

Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.
