Process industries across the globe grapple with producing dozens or even hundreds of different products.

Refinery revamp opportunities with welded plate heat exchangers

Kauders, P., CDE Projects Ltd.; Broad, R., GESMEX Exchangers GmbH

The plate-and-shell (P&S) heat exchanger has three significant advantages over the shell-and-tube (S&T) type traditionally used in refinery processes.

Fatigue damage assessment of coke drums based on temperature monitoring

Soare, M., Minea, I-S., Predoi, M. V., Bunesco, C., Diba, C., Nuclear NDT Research & Services Srl

Coke drums are expensive equipment with a long manufacturing cycle, so a realistic and accurate life prediction can save significant time and money.

Asset life assessment: A strategic reliability tool for the process industries

Pyne, T., Reliability and Asset Strategy Specialist

Asset life assessment (ALA) has become a strategic tool for process plants (e.g., petrochemical, chemical, and oil and gas) to determine the extent of degradation and the ability of assets to bear static and dynamic loads while sustaining the desired production processes.

Best options for a reboiler revamp

Pramanik, R., Srinath, N. R., Fluor Daniel India

It is always a challenge to reconfigure and resize existing reboilers, especially vertical thermosiphon ones, for the revised design and operating conditions of a brownfield project, since hydraulics external to the reboiler must match the reboiler hydraulics under the revamped conditions to ensure trouble-free operation.

Analyze machinery failure data with a spreadsheet

Perez, R. X., Consultant

Some basic, yet insightful, machinery reliability tracking tools are introduced here that can be developed with common spreadsheet applications, such as Excel.

Pumps handicapped by not using best available technology

Bloch, Heinz P., Hydrocarbon Processing Staff

Pump lubrication deficiencies are often denied, and the outstanding reliability performance of oil mist is vastly underreported.
