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..
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 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 ..

How caustic stress leads to failures of incinerator caustic spray nozzles
Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.
Extend heat exchanger lifecycle with hyper-duplex stainless steel
Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.
