Improve thermodynamic equilibrium among light olefins in FCC operations
Worldwide propylene demand is strongly increasing. About 28% of the global propylene supply comes from refinery fluid catalytic cracking (FCC) units. The light olefins have relative selectivity due to..
HP Viewpoint: Ethylene production growth drives new global industry standards
Operators that understand global market drivers and the latest technologies will provide the best solutions to improve their profitability and comply with the latest HSE rules.
Reduce moisture intrusion in pipes, tanks and other equipment
Once water enters the system, even at high temperatures, the insulation system can retain large quantities of water. That can then lead to accelerated heat gain or loss.
Address inlet pressure loss concerns with restricted lift relief devices
For the past 30 years, standard-sized relief devices have been sized such that it is difficult to meet the installation criteria in American Petroleum Institute (API) standard (STD) 520. This problem ..
HP Industry Perspectives: The best modern-day inventions according to chemical engineers

Country spotlight: KazakhstanAccording to data from the Kazakhstan Ministry of Oil and Gas, the country’s three oil refineries processed nearly 14.3 million tons (MMt) of crude in 2013. The 2013 ..
Case history: Characterization of shale oils and heat exchanger performance
LTOs are paraffinic, low in asphaltenes but high in filterable solids. Understanding the impact of these mechanisms can shed light on preheat exchanger performance and the prediction of fouling rates.
Improve the isomerization of alkanes by catalytic distillation
The isomerization of light gasoline fractions is crucial to producing high-octane fuels and to reducing the benzene content in gasoline. One of the most promising options for isomerization is catalytic distillation.
Wide design margins do not improve engineering
Engineers use design and safety factors in sizing and specifying instrumentation or major process equipment, such as pumps, valves and compressors. Design factors are applied to cover the uncertainty ..
HP Reliability: Was that a failure or ‘just a repair’?
Purists among reliability professionals are sometimes concerned about the accuracy of the measurement of the mean-time-between-failure (MTBF) of an asset. There are many ways to conduct this failure f..
