Process Optimization
Revamped FCC debutanizer yields flexibility with more capacity
Since not achieving goals from an earlier retrofit, a refiner investigated this column's distillation internals to maximize value creation
HP Water Management: Sacrificial anodes in cooling water systems
Cooling water chemical treatment programs are designed to control deposition and corrosion. In most systems, there is a trade-off between corrosion and deposition control. When the chem..
Producing product and change together
These two process plant mandates seem to be in opposition. Here are some strategies for confronting the challenges
HP Water Management: Is it time to chemically clean your boiler?
Offline boiler cleanings used to be a very predictable event, especially in utilities. Deposits that form on the tube surfaces inhibit heat transfer and reduce boiler efficiency. Cleani..
Improve startup of an olefins complex
The operations team performed early dryout of plant systems before mechanical completion of the entire plant, thus enabling a trouble-free commissioning of new equipment
Distinguishing online optimization benefits from those of advanced controls
An FCCU case study illustrates the procedure
Consider modeling tools to revamp existing process units
In this case history, a refiner uses simulation models with plant test data to debottleneck a crude unit
HP Water Management: Whatever happened to deaerator cracking?
In 1983, three deaerators ruptured from cracking. Due to concern over potential cracking in other deaerators, many firms conducted independent surveys. Inspections by one refiner, Exxon..
Systematic procedure for reengineering process equipment
A refinery air-cooled heat exchanger problem illustrates the method
