Design, operation and troubleshooting of sulfur-handling plants: Challenges and practices
The transportation of large quantities of liquid sulfur is costly and often impractical since it requires a continuous supply of heat energy to maintain its liquid form.
Control valves for carbon sequestration applications
Greenhouse gas (GHG) reduction projects have become a focus for many nations around the world—carbon capture technologies are a way to reduce the release of carbon into the atmosphere and help contribute to meeting emissions targets.
The effect of viscosity on centrifugal pumps and predicting performance for different fluids
Centrifugal pumps are used for a wide range of applications and services in the refining industry. In today’s dynamic scenario, changes in pumped fluid characteristics are common, especially for transfer/loading pumps.
Liquid applications for ASME Section I service
Extensive guidance is available for relief protection of American Society of Mechanical Engineers (ASME) Boiler & Pressure Vessel Code (B&PVC) Section VIII process equipment for scores of applications, such as run-away reactions, distillation and heat exchangers. Sources include ASME, American Petroleum Institute (API) and the Design Institute for Emergency Relief Systems (DIERS), among others.
Innovations
Endress+Hauser’s newly developed iTEMP TMT31 temperature transmitter (FIG. 1) for analog 4-20mA signals is characterized by its long-term stability, high accuracy and ease of use for reliable temperature measurement.
New state-of-the-art in sulfur recovery?—Part 2: Environmental benefits
It is widely accepted that state-of-the-art sulfur recovery technologies utilize the modified Claus process as well as some extension technology on the tail gas.
Hot oil pump warm-up system best practices and failure case study
Many industries utilize pumps in hot applications, including oil and gas facilities.
2022 HP Awards Finalists
<em>Hydrocarbon Processing</em>, the downstream processing sector’s leading technical publication for 100 yr, has announced the finalists for its sixth annual <em>HP</em> Awards, which celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year.
Choosing the proper regulator configuration can reduce droop
Many factors go into selecting the proper regulator for your system. One of those factors is sensitivity to changes in outlet pressure as downstream flow fluctuates, which is often characterized as “droop” as illustrated within a regulator’s flow curve.
HRSG water/steam sampling: Do it right or face potential consequences
Many large industrial facilities—including refineries, and chemical and petrochemical plants—are increasingly turning to co-generation for process steam and power production.
