Natural gas for diesel replacement is an excellent opportunity for mineable oil sands operations to realize considerable fuel savings.
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..
Hydrogen (H2) is a key to efficient operation of refinery desulfurization units (DSUs). Process H2, both pure and recycled from DSUs, must be compressed to pressures up to 85 kg/cm2. Centrifugal compr..
Most engineers are familiar with adhesive-coated insulating tape used by electricians in the field and maintenance shop. If we use this tape in the engine compartment of an automobile, it will soon be..
Periodically, this author receives questions from readers throughout the world addressing what performance issues could be wrong with a centrifugal compressor that is vibrating. Note: It is impossible..
For many years, reliability-focused engineers have observed flawed procurement processes for mechanical equipment. Many requirements are supposedly aimed at the lowest possible lifecycle cost; however..
In this case history, a new monitoring system was installed on a critical service hyper compressor for a Middle East (ME) ethylene complex. This unit supported two 400 Mton polyethylene (PE) units; do..
