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

Dixit, P., Boroda India

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

Datta, A. K., Process Consultant

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

Forbes, B., AMETEK

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

Zardynezhad, S., TurboTech Consulting Corp.

Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.

Corrosion: Address damage caused by galvanic corrosion

Anwer, A., Qureshi, N., Contributing Writer

At petrochemical and refining facilities, it is common for U-clamps over piping runs to become corroded, sometimes to the extent where they are completely thinned out.

Stress qualifications for standard and nonstandard valves in piping systems

Various types of valves are used in refineries, petrochemical plants, fertilizer plants and utilities.

Engineering Case Histories: Case 110: A checklist for vibration analysis

Sofronas, A., Consulting Engineer

Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.

Safety: Addressing corrosion at petrochemical plants starts with carbon

Dalton, B., Thermo Fisher Scientific

Maintaining the structural integrity of a pipeline is a significant investment of time and resources for organizations in the oil and gas industry.
