Double-tubesheet heat exchangers: Necessities and challenges

Misal, P. M., Fluor

Among all types of heat exchangers, shell-and-tube heat exchangers are in huge demand for industrial applications.

Use infrared thermal imaging for pump system condition monitoring and early failure detection

Brashler, K., Alshahrani, Y., Saudi Aramco

Thermal imaging technology has evolved over the years, and investment costs have decreased significantly.

Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation

Nichols, Lee, Hydrocarbon Processing Staff

Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.

Determining the indeterminate

Chaudhuri, D., Fluor Daniel India Pvt. Ltd.; Van de Ruit, H., Fluor

Standards such as API, ASME and NFPA are applied widely in the refining industry.

Converting a petroleum diesel refinery for renewable diesel

Chan, E., Burns & McDonnell

As refiners consider renewable, low-carbon alternatives, renewable diesel—refined from agricultural products using petroleum refinery processes—is gaining traction.

The use of tube inserts in fired heaters

Martin, M., XRG Technologies

In 1896, Whitham1 reported the successful use of twisted tapes (originally called retarders, and now also called turbulators) to increase heat transfer in boiler fire tubes—their effectiveness in increasing heat transfer is well known.

Getting the most out of your process burner tiles

Baukal, C., Johnson, B., John Zink Hamworthy Combustion

It is often incorrectly assumed that the burner tile is simply a piece of refractory or firebrick. Nothing could be further from the truth.

Specifying internals in sour water strippers—Part 1

A sour water stripper (SWS) system is a common process in petroleum refineries and other processes where hydrogen sulfide is present.

Optimizing for viability—VDU revamp in a brownfield project

Revamping an existing column in an operating plant for higher throughput is a challenge, especially when the column is already operating at its rated capacity.

Stop oxidation and scale growth with high-emissivity coating

Poth, J., Integrated Global Services

Oxidation of external tube surfaces is responsible for metal loss at around 0.25 mm/yr, which limits tube life.
