Special Focus: Valves, Pumps and Turbomachinery
CFD modeling of mixing tees—Design of a thermal sleeve
Mixing tees—in which two fluid streams with different physical and/or chemical properties mix—are widely used in the petrochemical industry.
Working together, MTBR can be improved
This article provides an overview of the actions carried out in recent years at Repsol’s Cartagena refinery in Spain to improve the mean time between repairs (MTBR) of the plant’s rotating equipment.
Myth busting: Unlocking the hidden value of Coriolis flowmeters in refining
Process engineers must make many decisions to meet production targets, while maintaining the safe and efficient operation of a process unit.
External chloride stress corrosion cracking: Phenomenon and protection
After carbon steel, stainless steel remains the most commonly used material in the petrochemicals and oil and gas industries.
Improve API and ASME centrifugal pumps reliability with permanent magnet shaft couplings
Many factors reduce centrifugal pump reliability. Internal factors include pump design aspects, manufacturing deficiencies, maintenance deficiencies such as lubrication, or process related problems. Other factors are external: the shaft coupling is one of the external elements causing reduced mean-time between failures (MTBF) and pump life through misalignment, friction and unbalance forces.
Process effects on Coriolis flowmeter calibration
The oil and gas industry is increasingly installing Coriolis flowmeters as an alternative to the more traditional turbine and positive displacement meters.
Maintenance and Reliability
Improve stability of ammonia plant steam systems to reduce unscheduled plant shutdowns
Dyno Nobel runs a 2,300-metric tpd purifier plant in Waggaman, Louisiana.
Mitigate water-side fouling in fire tube boilers
One of the most important pieces of equipment used in many industries is the fire tube boiler.
Preventing and treating amine solvent foaming in tail gas treatment units
Amine systems in refineries and gas processing plants are used to remove H<sub>2</sub>S, CO<sub>2</sub> and mercaptans (RSH) from gas streams.
Design of deaerator storage vessel for hydrotest condition in fully assembled position
Deaerators are mechanical equipment used to remove dissolved gases from boiler feedwater to protect the steam system from the effects of corrosive gases.
Performance deterioration by weep hole in a lube oil cooler
The hydrocarbon processing industry (HPI) uses various rotating machines, such as pumps, compressors, blowers and turbines.
Cooling tower heat transfer basics—Part 3
Refineries, chemical plants and numerous other industrial facilities utilize open recirculating cooling systems equipped with cooling towers for cooling in scores of heat exchangers.
Process Control, Instrumentation and Automation
Avoid common data preparation mistakes to improve analytics results
Time series data preparation in process manufacturing applications presents complex challenges, such as differences in data sampling rates, inconsistent or custom units, and the need to access data in multiple systems, among other issues.
Improve grab sampling results and enhance analyzer accuracy
Accurate laboratory grab sampling is a delicate process, requiring operators to follow sound best practices to ensure accurate analyzer measurements.
Chemical treatment program for closed-loop cooling system
Closed-loop cooling water (CLCW) systems are utilized in areas where cooling is critical.
