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.
