Piping
Corrosion under insulation on stainless steel
Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs on stainless steel (SS) that has been insulated.
External pressure design of large-diameter piping: Optimal analysis approach
Large-diameter piping used in the petrochemical, oil and gas, steel plant and power industries often carry toxic fluids and can pose significant safety hazards.
Analyze pressure loss during FCC standpipe catalyst transfer
The fluid catalytic cracking unit (FCCU) is the primary conversion equipment for modern refineries to obtain clean transportation fuels, along with high-grade petrochemical feedstock.
Is coating required on stainless-steel components?
Stainless steel is a generic term used for a large group of corrosion-resistant alloys containing at least 10.5% chromium (Cr), and possibly containing other alloying elements like nickel (Ni), molybdenum (Mo), manganese (Mn) and nitrogen (N).
Good distributor design for high-velocity feed debottlenecks a crude preflash tower
Bazan Group’s crude unit No. 3—not designed by any of the authors’ companies—was bottlenecked by the preflash tower.
Isentropic effects: Application and simulation
A process safety risk in industry is having unknown problems that are not accounted for.
Improve the reliability of a CO2 compressor in a urea synthesis/granulation plant
The carbon dioxide compressor is one of the key major equipment in a urea production plant that produces fertilizers.
Challenges and pitfalls in brownfield EPC projects
Job requirements and scope are well defined in engineering, procurement and construction (EPC) contracts because they are designed and engineered from scratch.
High-frequency acoustic excitation—Part 2
Failure of a piping section at the outlet of pressure safety valves (PSVs) and control valves—where significant differential pressure exists (particularly in gas processing industries)—is a common problem in industries.
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.
