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..
FS-Elliott opens new US compressor service hub
FS-Elliott’s service center houses the global services group, a team of professionals responsible for providing a full portfolio of support including remote technical assistance, operation and maintenance training, and performance upgrades designed to further improve machinery operation.
Phillips 66 picks Elliott to supply compressor train for Sweeny refinery
The project will enable the refinery to meet the requirements set forth by the Environmental Protection Agency's (EPA) Tier 3 clean fuels standards, according to Phillips 66.
Top seven causes for lost olefin production
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
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%.
HP Innovations
A joint industry project (JIP) has been launched between Swagelining Ltd., Saudi Aramco and The Welding Institute (TWI) to conduct investigations into the use of polymer lining in carbon steel (CS) pipelines.
MAN supplies compressor to record air separation project in South Africa
With a production capacity of 5,000 tpd of oxygen, the ultra-modern facility pushes the technical boundaries that have existed up to now, also with regard to efficiency, reliability and safety.
Cameron LNG picks Elliott to supply compressors
When the new liquefaction facility becomes operational in 2018, it will enable bi-directional service between the terminal and the liquefaction plant.
Contain ‘normal’ leakage from primary seals
Dry containment seals have gained popularity over the last few decades and provided reliable service. The refinery sector has used this sealing technology to limit fugitive emissions in a cost-effecti..
HP Engineering Case Histories: Case 83: What are useful questions to ask before starting a vibration analysis?
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..
