HP Reliability: Things to know and do before starting new initiatives

Bloch, Heinz P., Hydrocarbon Processing Staff

HP editors frequently attend technical conferences to keep informed on the many factors impacting the hydrocarbon processing industry (HPI). The focus of these conferences often differs. However, one ..

Automate furnace controls to improve safety and energy efficiency

Mickity, D., Phillips 66

Furnace firing is the biggest single operating expense in any refinery. Consider a medium-size refinery (250,000 bpd) that consumes 2,000 MMBtu/h. At a cost of $5/MMBtu, that’s $87.6 MM/yr being ..

Use online conditioning to monitor electric motors

Wilhelm, B., GE Measurement and Control; Neti, P., GE Global Research Center

Quality and health assessments of motor insulation are important aspects during the manufacturing, as well as the operation, of electrical motors. Today, there are several offline insulation quality a..

HP Reliability: Make equipment decisions with up-to-date technical information

Bloch, Heinz P., Hydrocarbon Processing Staff

Answering lube practice-related questions is important. These questions provide insight on the status of education and technology, along with trends in understanding equipment reliability, safety and ..

HP Reliability: Small deviations can compromise equipment reliability

Bloch, Heinz P., Hydrocarbon Processing Staff

In 2013, a major refinery was experiencing serious pump problems. The refinery had a massive thrust-bearing failure on a critical 3,560-rpm pump. The pump was designed and manufactured by a well-known..

Consider new steam system corrosion protection for refineries

Dale, T., Robinson, G., Rossi, A., GE Water & Process Technologies

New technology in volatile filming corrosion inhibitors and lower-salting neutralizing amines can provide cost-effective solutions for the steam-condensate system and minimize the risk of amine chloride salt formation.

HP Reliability: Consider single-point responsibility for compressors

Bloch, Heinz P., Hydrocarbon Processing Staff

Equipment purchasers are always interested in meeting the cost and schedule targets for projects. However, there could be conflicting goals when purchasing compressor drivers and/or auxiliaries from v..

HP Engineering Case Histories: Case 77: Random deck vibration with beats

Sofronas, A., Consulting Engineer

When something vibrates, it is usually in a predictable manner. Motors, pumps, compressors, turbines and centrifuges all vibrate when they are out of balance. Vibration analysis can help predict the s..
