Heat Transfer
Rethink placement of preflash drum in crude preheat train network
Strategic location of the preflash drum not only resolves network problems, but, in some cases, reduces operating costs
Selecting the right steam trap
In addition to the type, consider the installation, maintenance and wasted energy costs during its operating life
Understand the difference between solid and serrated fins
Here are the advantages and disadvantages of each type and how to calculate their surface areas and efficiencies
Optimize air-cooled heat exchanger performance
Use these guidelines to troubleshoot and correct cooling problems
Optimizing O2 levels in fired heaters
Here's the procedure this plant used to reduce fuel consumption and emissions
Selective withdrawal flows from storage tanks
Using this technique can improve costs and product quality
Update design and maintenance methods for refractory systems
Better design methods and repair efforts reduce failure of these systems
Solving hydraulic problems in crude preheat train networks
Heat transfer and hydraulic problems need to be considered simultaneously
High temperature air combustion for steam reformers
This novel technology can reduce facility NOx emissions
Repair critical-service exchangers with innovative methods
In this case history, unconventional maintenance techniques stopped chronic leaking for an olefin's heat-exchanger circuit
