Stability analysis of debutanizer columns with hot-vap or bypass pressure control
A debutanizer column was experiencing unstable operation, with frequent pressure swings and product composition fluctuations from the column overheads system.
Ensure a truly rigorous relief valve sizing method
Pressure relief valves (PRVs) protect equipment from excessive overpressure and, in case of emergency situations, they should ensure a sufficient discharge of mass to reduce the pressure below the recommended pressure limits.
Digital: Looking to boost safety? Reliable operations are the key
Equipment failures are the thorn in every industrial plant’s side.
Digital: Maximize return on capital investment with predictive maintenance
Oil and gas professionals are well aware of the pressures companies face in the market.
Show Preview: IRPC Europe returns to Italy this June
Gulf Energy Information and Hydrocarbon Processing are pleased to provide a preview of IRPC Europe 2018, which will be held June 5–7 in Milan.
Using valve diagnostics at startup to save time and money
Early detection of valve problems with diagnostics prevents small issues from escalating into major incidents when production starts.
Innovations
Ross Systems and Controls (SysCon) recently completed the qualification to self-certify its touchscreen purged panels as meeting the rigorous standards of Underwriters Laboratories’ UL-698A Code and the National Fire Protection Association’s NFPA-496 Code.
How the “LLF” condition monitoring technique can improve manufactured product profitability
Technological advances have allowed predictive maintenance (i.e., condition-based maintenance) to overtake preventive maintenance in plant operations. “Look, listen and feel (LLF)” is a condition monitoring technique that improves the reliability of equipment and machinery in manifolds.
Migrating from Fortran to ISA S-88
A major refiner operates two catalytic reforming units for gasoline octane improvement and aromatics production in Texas. In each of these units, five reactors filled with catalyst are operated continuously in series to reform paraffinic hydrocarbons in the presence of hydrogen (H2). During this process, some byproduct coke is unavoidably produced and deposits on the catalyst, which leads to gradual catalyst deactivation.
