Doing more with less: Extending critical fluid system resources

Menz, B., Swagelok

Fluid system operators are tasked with maximizing value from their systems to enhance plant and refinery operations.

Refining: Despite decline, Group 1 base stocks are here to stay

Nadasdi, T., ExxonMobil

Given increasingly stringent automotive specifications and the advent of the International Maritime Organization’s 2020 sulfur regulations, the continued decrease in Group I base stocks demand should come as no surprise for anyone in the industry.

Variable capacity control technology facilitates efficient operation for reciprocating compressors

Sanford, J., Siemens

Reciprocating compressors are used extensively in refinery and petrochemical operations to keep feedstocks and products moving through miles of piping.

Design of very-high-flow coefficient centrifugal compressor stages

Jariwala, V., Elliott Group

Centrifugal compressors are widely used in the oil and gas and petrochemical industries, with more than 15,000 operating in the U.S. alone.

Effectively clean air fan coolers with water and steam

In many refineries and petrochemical plants, air fan coolers (AFCs) become a major bottleneck to increasing plant capacity. Many plants suffer from lower heat duty than designed, especially during the summer months, which can lead to lower plant capacity.

Leveraging modern flow technologies to improve safety in refineries

The refining industry is facing increased pressures, such as crude oil supply changes, changing product distributions and increasing regulations. These pressure points create a highly competitive market where refiners are looking for options that include digitally transforming operations and adapting new technologies to enhance safety and improve uptime, flexibility and efficiency, while securing their competitive position in a dynamic market. Improving personnel and process safety remains a top focus area for refiners.

Reveal the unmonitored risks in your rotating equipment: The effects of torsional vibration—Part 2

O’Connor, D., Gutierrez, J., Bently Nevada, a Baker Hughes Business

In recent case studies, unexpected and unmonitored torsional vibration resulted in sudden failures, costly downtime and potential safety hazards. Part 1 of this article, which appeared in the January issue of Hydrocarbon Processing, examined the origins of torsional vibration and case histories to drive an understanding of the unmonitored risk existing at many industrial sites.

Reveal the unmonitored risks in your rotating equipment—Part 1

O’Connor, D., Gutierrez, J., Bently Nevada, a Baker Hughes Business

On December 15, 2002, an anomalous event occurred in a steam turbine of Unit 2 at the South Texas Project Electric Generating Station, a pressurized water reactor (PWR) nuclear reactor near Bay City, Texas. The ensuing investigation concluded that a blade was ejected from a low-pressure stage, and detailed inspections revealed additional cracked blades in several stages.

Reliability: Things rarely heard at reliability conferences

Bloch, Heinz P., Hydrocarbon Processing Staff

We can only guess how many reliability conferences we have attended since accepting job offers in the refining or chemical processing industries. In my case, starting in 1965, it is somewhere between 60 and 80. If, in each of these conferences I listened to six presentations, the number of sessions attended is perhaps 400.

Business Trends: EPC 2030: Five vital characteristics that will define the EPC firm of tomorrow

Donnelly, P., AspenTech

The state of the global engineering, procurement and construction (EPC) industry can accurately be described as “challenging.” Operating in an environment of volatile, uncertain, complex and ambiguous conditions, EPC firms are facing unsustainable levels of stress.
