When frequent fouling of the vacuum column was constraining the run length of PTT Global Chemical's (PTTGC) vacuum distillation unit (VDU) to significantly less than the downstream hydrocracker's three-year cycle, the refiner was quick to take decisive action. Discover how with a low-cost revamp of the unit to a Shell HVU using Shell's deep-flash, high-vacuum technology, the unit is now equipped to achieve run lengths in excess of three years.

Refiners continuously search for the best available options to maximize the return on investment for purchases. Since catalyst purchases are reoccurring and typically planned, these investments are critical to meeting financial targets. The optimum catalyst solution may incorporate different amounts of existing catalysts, replacement of one catalyst for another, or possibly a new, innovative catalyst approach to meeting refinery objectives. This paper examines three different refinery intentions related to catalyst selection for an upcoming hydrocracking unit reload: 1) reducing catalyst spend, 2) improving steady state operation, and 3) meeting new refinery objectives.

Lubricants are comprised of base oil and an additive package. Additives make up as much as 30% of the formulated lubricant and often contain elements such as phosphorus, calcium, and zinc. Petra MAX™ offers a simple analysis technique to measure these elements and ensure that blended lubricants meet the required specifications.

For years, single seals were the go-to option for North American refineries and petrochemical companies, but now the industry preference is shifting toward dual seals. Learn about the trends driving dual pressurized seal adoption and how they are helping refineries and petrochemical plants lower emissions, increase safety, improve reliability and reduce costs.

The new Rosemount™ 928 Wireless Gas Monitor extends toxic gas coverage to applications previously too challenging and costly to monitor. This white paper focuses on the complexities of remote H₂S gas monitoring, wireless gas detection technology cost advantages, and device features that take wireless gas monitoring to the next level.

Adopting a risk-based approach to cybersecurity can help you make strategic decisions based on the likelihood and impact of each vulnerability. Emerson’s Cybersecurity Guidebook highlights six strategies to help protect your process control system and network against potential threats.

• Tighten System Access
• Establish Strong Policies
• Upgrade to a More Secure Control System
• Go Beyond Perimeter Protection
• Keep Remote Access in the Right Hands
• Know Your Control System

The procedure for selecting the best automation technology is not as easy as it once was. Recently, technologies have evolved so the functionality between the types of tools has appeared to converge.

In this white paper, we will shift away from some of the classic stereotypes of DCS, PLC, and SCADA to help show which system will best meet your goals.

In the modern blending plant, spectrometric analysis is no longer a matter of just measuring common lubricating oil ingredients and contaminants. Magnesium (Mg), phosphorus (P), calcium (Ca), and sulfur (S) aren't enough. As formulations grow more complex and additive packages proliferate, you may need precise analysis of elements from tungsten (W) to cobalt (Co) to bismuth (Bi) — as many as 27 in total. Can your existing instrument handle all these? If not, consider advanced new ED-XRF models such as the SPECTRO XEPOS analyzer. It can measure them all, using only a single analytical method! And it delivers everything else your lab requires, from precision and throughput to lower costs and greater ease of use.
