Use computational fluid dynamic analysis to revamp fired heaters
A refinery process fired heater system consists of multiple sub-units, of which the fired heater is the most critical, as it impacts the overall efficiency of the system.
Calculate thermal efficiency to optimize fired heater operation
In a Saudi International Petrochemical Co. petrochemical plant, fired heaters are designed to supply heat duty at 7 MW and are one of the major consumers of energy.
Minimize unplanned shutdowns of fired heater operations
There are many potential “rules,” or guidelines, for the safe operation of process heaters.
Control fouling on preheat trains with a two-stage approach
Fouling in heat exchanger preheat trains is a well-known problem in the refining industry.
Alfa Laval to supply heat exchangers for Korean petrochemicals complex
The order comprises the delivery of Packinox heat exchangers which will recover energy in the production of mixed xylenes, ingredients in the manufacturing of synthetic nylons and PET bottles.
Mitigate vibration issues in shell-and-tube heat exchangers
Heat exchanger tubes tend to vibrate when influenced by crossflow velocities.

The FM-approved FireChek thermal shutoff valve with resettable memory shape alloy can now be used to automatically shut down a pneumatic control system when a nearby fire occurs, or when the ambient temperature reaches 135°F, 150°F or 165°F.
GEA Heat Exchangers changes company name to Kelvion
Due to a change of ownership, the company previously known as GEA Heat Exchangers says it is now ready to take on global competition under the name Kelvion.
HP Refining: Maintain plant production with temporary heat exchangers
Of all the process operations in a refinery or petrochemical plant, heating and cooling streams are perhaps the most pervasive.
