Refiners, when faced with a turnaround or unscheduled maintenance face pressure to complete the project on time. However, research suggests few projects finish on time or ahead of schedule. Thus, a critical factor to staying on or ahead of schedule and returning to profitability is having the towers, drums, and systems decontaminated and cleaned as quickly and safely as possible allowing for personnel entry maintenance without fresh air required. Detailed planning has proven to be a determining factor in a decontamination project's success.

Is it time to rethink your distributed control system (DCS) expectations and capabilities? Reliable and effective control systems are critical for safe and profitable operations across process industries. Still, many industrial facilities today continue to operate using legacy control systems from the past four decades, often nearing the end of their lifecycles. Migrating to modern control systems can be a complex venture. These projects require detailed upfront planning, a methodical implementation strategy, and astute project management.

With increased concern around data quality, calibration matrix matching has shown to improve low-level ASTM D2622 sulfur measurement accuracy to ensure regulatory compliance for gasoline. This bias correction combined with good analyzer precision can also help refiners reduce costs and decrease sulfur giveaway. Download our whitepaper to learn more.

Find out how GTC Technology’s Uniting Wall Column provides several advantages and benefits over conventional cryogenic or non-cryogenic LPG recovery processes.  GT-UWC^℠ is a process uniting the functions of the deethanizer and depropranizer into one column to achieve higher C3+ recovery at lower operating temperatures and pressures. As a result, both capital investment and operating costs for grassroots and revamped applications are reduced.

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.
