Reliability: Houston: We have another problem

Bloch, Heinz P., Hydrocarbon Processing Staff

The state of understanding science and facts on one side and distinguishing these from anecdotes and far-fetched opinions on the other side, should be concerning to us.

Control valve design challenges for green diesel processes

Prusha, J., Emerson Automation Solutions

Green (or renewable) diesel is a biofuel that offers several advantages over biodiesel, so many refineries are increasingly including it in their production portfolios.

Assessment of independent protection layers in an LOPA study—Part 1

Patel, H. J., Fluor

Industrial facilities, especially those operating in the chemical, oil and gas and petroleum industries, contain inherent risks in operations due to the processing of materials that are hazardous in nature.

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

Aguirre, M., Cowan Dynamics

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)”.

PSV sizing: An alternative solution to the homogeneous direct-integration method

Hojjati, H., Hojjati, B., WSP Canada Inc.

Pressure safety valves (PSVs) are designed to protect personnel and plant properties from an overpressure occurrence in equipment or piping by relieving fluid to a safe location.

Keeping fugitive emissions costs down with low-E valves

Hunsicker, S., Swagelok

Fugitive emissions have become an increasingly critical area of interest for chemical processing and refining facilities.

Case study: Reliability of low-flow, high-head pumps

Badughaish , M., Saudi Aramco
