Advanced process control metrics: Closing the loop on APC performance
For more than 30 yr, advanced process control (APC) has established itself as an important and relatively routine and valued part of the industrial process control and operation landscape.
Dynamic simulation for FGRS design and controllability analysis
In this study, a dynamic model of a flare gas recovery system (FGRS) with a high-pressure eductor compression system was developed in a dynamic simulation for process design verification, control scheme evaluation and an availability study.
Improve refinery production and efficiency with asset monitoring
The sheer volume of equipment in a refinery—from vessels, columns, huge structures and mazes of pipes to pumps, valves, controllers and instruments—is staggering.
Onsite
Jenny Hebert and George Yaluris of Albemarle accept the <i>HP</i> Award for Best Catalyst Technology.
Engineering Case Histories: Case 103—Addressing heat exchanger tube leaks
Heat exchangers have multiple tubes with fluid passing through and over them that either heats or cools another fluid.
More residue processing in FCCUs
Resid units have more than 2 wt% Conradson carbon residue (Concarbon) in feed and more than 5,000 parts per million (ppm) of nickel (Ni) and vanadium (V) on equilibrium catalysts (Ecat).
Understand the installation of steam tracing for long-term application success—Part 2
One of the most misunderstood and misused components of conductive steam tracing systems is heat transfer compound (HTC).
Amine pumps upgraded for improved operations and reliability
A gas processing plant in Malaysia eliminated a source of expensive failures in its acid gas removal unit (AGRU).
Integrating fire and gas safety with process control systems: Why, what and how
If a fire, smoke or gas leak is detected in a hydrocarbon processing facility, prescriptive actions must be taken by the fire and gas (F&G) safety system, as well as by the process control system (PCS), to mitigate and control the hazard.
Built-up backpressure at the outlet flange of a pressure relief valve
Even for pressure relief valves (PRVs) discharging directly to the atmosphere through short tailpipes, API 520 Part 11 warns that choked flow may develop at the outlet flange, resulting in high backpressure.
