Editorial Comment: Petrochemicals: Changing technologies and configurations to satisfy future demand
For nearly a decade, capital investments in new petrochemical capacity have skyrocketed. This
Strategies to minimize piping thermal maintenance system cost without compromising performance
Where process fluid must be maintained within a certain operating temperature window, the piping will likely require the application of a thermal maintenance system.
Double-suction centrifugal compressor in ethylene plant inlet piping design
Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.
Optimizing failure data analysis
A critical objective of engineers who design an automatic protection system is to lower the false trip rate and to lower a key metric called average probability of failure on demand (PFDavg).

Sour water stripping is a common process in petroleum refineries and other processes where hydrogen sulfide (H<sub>2</sub>S) is present.
Best practices for pygas-based styrene extraction
Pyrolysis gasoline (pygas) is a by-produced fraction of hydrocarbons generated from a steam cracker.
Fuels and chemicals: Finding the right refinery configuration for a less predictable world
The refining industry links the upstream production of crude oil with the end markets for fuel products, as well as for the petrochemical/chemical industry.
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.
