Consider new labyrinth seals to optimize compressor operations

Gresh, M. T., Flexware, Inc.; Whalen, J. K., John Crane Engineered Bearings

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

Kaupert, K., Energent; Krull, R., Iles, R., Energent Corp.

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

Bloch, H. P., Professional engineer

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..

Use new methods to optimize energy efficiency of hydrogen compressors

Vila Forteza, M., Repsol SA

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..

Top seven causes for lost olefin production

Cagnolatti, C. L., HSB Solomon Associates LLC

Long-term trends in production losses, showing total loss production measured in seven biennial studies, are discussed in this article to determine if these losses are increasing or decreasing over time.

Use multistage integrated chilling to increase ammonia production

Arora, V. K., Kinetics Process Improvements, Inc.

A new revamp approach for ammonia plants uses multistage integrated chilling (MIC). The MIC scheme provides an option that avoids expensive compressor upgrades for incremental improvements in ammonia production, with energy efficiency improvements up to 15%.
