Redundant control pilot valve system adds reliability in downstream operation

Emerson: Boltniew, G.

In downstream processing facilities, such as refineries and chemical plants, downtime is a significant source of lost revenue.

Air-to-air pneumatic booster fail-safe system for valves

Cowan Dynamics: Aguirre, M.

In pneumatic valve automation systems, it is common to hear the following terms for valve positions: “fail open (FO),” “fail close (FC)” and “fail last (FL)”.

Advanced methods for controlling boiler tube corrosion and fouling—Part 1

ChemTreat, Inc.: Kraetsch, K.  |  Buecker, B.

Many heavy industrial plants, such as refineries and petrochemical facilities, require steam for numerous processes, including powering turbines, providing energy for a variety of unit operations and even heating buildings in some locations.

Materials management: Data-centric execution to enhance organizational productivity—Part 1

Bechtel Corp.: Wyss, S.

As a veteran of many capital projects once observed, “All projects execute materials management—those that do so without a plan and the appropriate resources just do it very poorly.”

Monitoring hydrogen plant performance—Part 1

Johnson Matthey Process Technologies: Ramakumar, K. R.

Process monitoring is an indispensable practice to keep track of key performance indicators (KPIs) of the hydrogen (H<sub>2</sub>) plant.
