Consider new labyrinth seals to optimize compressor operations
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..
Maximize energy recovery with small steam turbines
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.
Lubrication update for rotating equipment
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..
Improve relief-device sizing under supercritical conditions
Properly sized relief devices under supercritical conditions are vital to processing natural gas and gas condensates into olefins. These processes operate near the critical locus of the process gases ..
Improve measurement of heavy oil viscosity
This work will study the viscosity behavior of bitumen and its blends with diluent at different temperatures, as well as evaluating simulations for prediction of viscosity of the blend.A blend of bitu..
Use new methods to optimize energy efficiency of hydrogen compressors
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..
HP Reliability: Reassessing and updating electric motor bearing lubrication
Over the past 25 years, this column has often dealt with electric motor lubrication. As listed in the recommended reading list, this subject is often asked and, of course, there are updates to the rec..
HP Automation Strategies: Developing the best practices for operator effectiveness in the age of collaboration
Multiple converging trends make operator effectiveness even more important today than ever before. These include: loss of expertise in industrial plants and the transition to a new workforce, business..
HP Project Management: Build a better bid, or how to achieve a competitive advantage in capital projects
As backlogs and revenues continue to be strong and on an upward path for most global engineering and construction (E&C) firms, competition for the best projects has increased. The energy industry’..
HP Engineering Case Histories: Case 84: Remaining service life of plant equipment can be determined
For new plant machines and equipment, the life expectancy is determined by the original equipment manufacturer (OEM). Yet, different analysis techniques are often required in a failure analysis. In a ..
