Oil refineries and large petrochemical plants contain thousands of pieces of process and utilities equipment that are subject to wear, erosion, deterioration, aging, etc., resulting in increasing breakdowns and outages. Imagine being a maintenance engineer and receiving 50 work orders during an overhaul with a limited budget, time, labor, spare parts, tools, machines, etc. How does that engineer prioritize the work?
This case study aims to provide the root cause analysis behind bearing failure of an induced (ID) fan at a new refinery startup in 2015.
The drop in crude oil prices since 2014 has impacted both upstream producers and downstream players. Upstream producers—those responsible for exploration, drilling and production—were the first to feel the effects. While refining margins benefitted from the drop in crude oil pricing, they began to suffer when record surpluses of gasoline and diesel flooded the market a year later.
A scientific study was undertaken to evaluate the performance, under dry running conditions, of two types of diamond coatings applied to silicon carbide faces of mechanical seals.
Part 1 in this series, “Build a diesel fuel performance additive, the right way,” (Hydrocarbon Processing, October) detailed the required chemical additives and test methods for achieving ideal engine performance and fuel economy.
NEO Monitors’ mid-infrared (IR) sensors will help global industries better control emissions of nitrogen oxides and sulfur oxides.
Hubs connect one piece of machinery to another, usually with some flexible coupling between them. Installers have only limited time to work with the hot hub. When incorrectly positioned, it may have to be removed, which has the potential of damaging the shaft end.
Degradation of labyrinth seals in centrifugal impellers can have a significant impact on not only compressor power consumption but also on plant production rate. Upgrading to rub-tolerant seals can be..
Using smaller turbines (50 kW to 300 kW) can aid system efficiency and help conserve energy. We investigate examples in which the application of smaller steam turbines provided return on investment within two years.
API-610 is the most widely used pump standard in the petrochemical and refining industries. It includes experience-based recommendations for lubricant applications and one of those recommendations rel..
