Guyed structures are common in petrochemicals, oil and gas and chemical industries. Half of the installed flare structures at many facilities are guyed. Various routine inspection programs are in place to examine these structures. This work describes some very basic checks, which should be in place to maintain their mechanical integrity.
Shock pulse technology is generally well known to vibration analysts and reliability technicians. A handheld combination of sensor and display meter would typically be used to detect discontinuities in bearings and would respond to the impact of two masses. The resulting shockwaves will create a shock pulse of a certain magnitude that commonly manifests itself at a particular repeat frequency. The respective magnitude of relevant excursions and their trends can be observed by the person entrusted with the monitoring task.
Due to Tropical Storm Imelda, Hydrocarbon Processing issued its first force majeure in postponing the third annual HP Awards.
Ball valves are often an economical solution for controlling flows in refinery high-temperature applications, but their application can be complex, particularly in high-temperature uses.
Refineries consume large amounts of energy and water to refine crude oil into products. Up to 10% of crude oil’s energy content is consumed during processing, and it takes 1.5 bbl of water to process one barrel of crude oil. Refining processes also generate large quantities of excess thermal energy that needs to be expelled into the environment using a once-through or recirculating cooling system.
Hydrocarbon Processing, the downstream processing sector’s leading technical publication, has announced the winners for its third annual awards. The HP Awards celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.
The need for a solid cybersecurity strategy has been discussed and debated for nearly half a century. However, the basic worm-type attacks first documented in 1972 are still with us today. Why? The reason is because even the most basic measures to protect control systems from these types of attacks are still not systematically employed.
In 1864, James C. Maxwell predicted the existence of radiowaves by means of a mathematical model. The so-called Maxwell equations are the most famous and successful formulas. In 1884, John H. Poynting realized that the Poynting vector would play an important role in quantifying electromagnetic energy. In 1888, bolstered by Maxwell’s theory, Heinrich Hertz first succeeded in showing experimental evidence of radiowaves using his spark-gap radio transmitter. The prediction and evidence of radiowaves were the beginning of wireless power transfer (WPT).
Two of the terms growing in popularity over the past few years are “digital native” and “digital immigrant.” Natives are those individuals young enough to have known computers and the internet since childhood. For them, such technologies have always existed. Immigrants, either through age or circumstance, had no exposure until later in life. Hopefully, for them, such technologies are a welcome addition to work and life, but they can remember times when most activities were more manual, local and isolated.
ARC Advisory Group’s 23rd annual Industry Forum included a panel discussion that explored the relative merits of integrated vs. non-integrated safety systems in an increasingly connected world.
