Isomerate is useful because it is paraffinic and contains no benzene, aromatics or sulfur. This pentane and hexane fraction of crude oil is known as light naphtha. The main objective of reactions is to increase the research octane number (RON) of the components. Decreasing fuel consumption without changing the product RON of isomerization units is discussed here.
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.
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.
There are many potential rules, or guidelines, for the safe operation of process heaters.
The four case studies cover component failures and multiple types of leakage: valve packing, expansion joint and corrosion.
Fouling in heat exchanger preheat trains is a well-known problem in the refining industry.
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.
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.
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.
