What are the benefits of rigorous modeling in heat exchanger design?
This article examines three applications where rigorous heat exchanger models can boost value derived from process simulation and provide more accurate results.
Prevent external corrosion of boiler tubes under refractory lining
A leak developed on the water wall for several boiler tubes within five months of the commissioning of a plant boiler. In this case, the boiler tubes were partially covered with a castable refractory ..
Largest ethane cracker: Borouge’s Ruwais manufacturing complex
The latest expansion project includes an ethane cracker (EU3), two PE and two PP plants, and a low-density PE (LDPE) unit.
HP Engineering Case Histories: Case 69: Heat-up rate and rubs on a steam turbine
This column has suggested using simple analytical models to troubleshoot equipment. However, in some cases, a more detailed solution may be required. The following case histories examine the heat up o..
HP Water Management: Avoid failures in water projects: Part 2
Last month, we discussed the need for project engineers to talk to process engineers about the water systems as a capital project takes shape. This month’s column discusses additional ways to bri..
Achieve optimal heat recovery in a kettle exchanger
Improve operations by avoiding buildup of sensible duty or by using baffles
Debottleneck crude-unit preheat exchanger network inefficiencies
Simulation models can be effectively used to optimize heat transfer and boost operational performance
Selecting the right steam methane reformer: Can vs. box design
Simulating various configurations and cost estimates aids in the selection of a steam methane reformer for hydrogen production
Investigation: Failure of a steam generator
In case history, engineers search for root cause of water-side tube failures for a 23-year-old boiler
HP Water Management: Don’t let water be the reason for a turnaround
Several years ago, while arriving onsite during another unit turnaround, I joked to a process engineer at the refinery “I get it. . . every time I ‘turn around,’ you have a turnaround.&..
