HP Project Management: Case history: Hurdles in dismantling a vintage ammonia plant
Dismantling an ammonia plant is a daunting task under any circumstances. It is even more problematic when the facility is located in a remote place such as central Pakistan and managed by local contra..
HP Project Management: Pipeline expansion uses rerating to debottleneck services
The Colonial Pipeline connects refineries primarily on the US Gulf Coast with customer service markets across the southern and eastern US. In 2010, Colonial’s 5,500-mi pipeline was transporting a..
Improve performance of exchangers in quench-water services
Dual-enhanced (DE) tubes are widely used in shell-and-tube heat exchangers (HEXs) in a range of industries. They have become a standard in multiple clean services for the hydrocarbon processing indust..
HP Engineering Case Histories: Case 79: Integral compressor failures
Recently, the author received information regarding the failure of a large reciprocating compressor. In this example, the pistons for power and compressor cylinders are powered by the same crankshaft...
Honeywell automation technology selected for Asian gas pipeline
Asia Trans Gas selected Honeywell's Experion Process Knowledge System and Safety Manager technology to manage operations and to help prevent safety problems in a third pipeline to be built as part of the Central Asia–China Gas Pipeline project.
Evaluate piping for displacement-controlled loading
In a Canadian case study, new piping under construction suffered some settlement in the underground portion, as evidenced by soil movement and slight deflection of the above-ground section.
Continuous corrosion monitoring enhances operational decisions
Operators with permanently-installed continuous corrosion monitoring systems have better understanding of the corrosion and erosion rates occurring within their facility.
Reduce moisture intrusion in pipes, tanks and other equipment
Once water enters the system, even at high temperatures, the insulation system can retain large quantities of water. That can then lead to accelerated heat gain or loss.
Consider new steam system corrosion protection for refineries
New technology in volatile filming corrosion inhibitors and lower-salting neutralizing amines can provide cost-effective solutions for the steam-condensate system and minimize the risk of amine chloride salt formation.
Reciprocating compressors running together—Is that a problem?
A new maintenance engineer is assigned the task of overseeing large, critical rotating equipment in a petrochemical facility (Fig. 1). In this example, the facility has vent-gas compressors that, in g..
