Reduce maintenance and production losses by benchmarking asset performance
Benchmarking can help operators identify assets with chronic failures, and it can also drive failure elimination efforts to improve their reliability and availability while cost cutting.
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.
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 ..
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..
