Why do outlet collectors only rarely fail, even when subjected to pressure-drops well above the design basis of the collector? The answer lies in the design approach which incorporates simplifying assumptions to accommodate a tractable and conservative approach. These conservatisms can be relaxed where necessary to give results much more in line with actual experience […]
Introduction Operational reliability is a priority for any process unit facility. A definition of Reliability is: “The ability of an apparatus, machine, or system to consistently perform its intended or required function or mission, on demand and without degradation or failure.” Reliability is something that owners and operators consider a priority, but achieving stable reliable […]
Current market conditions are forcing many refiners into an unfamiliar operating state. A different approach may be required to rebalance and reduce refinery intake and maximize products that are still in demand. Unit and equipment specific impacts of this approach will depend on the severity of the rate reduction as well as the duration. As […]
Becht is pleased to announce the grand opening of our Buenos Aires, Argentina office in February 2020. Mariano Bertaina, former Executive Technical Director of the Axion Refinery, will serve as Becht’s Director, LATAM Operations. Derek Becht, VP Plant Services, commented that “This is an important step forward for Becht allowing us to better serve our […]
Here’s How To Get On Track There are two sure things in life: Death and Taxes. There are other things in life that are not for sure, nor pre-ordained, but stand a pretty good likelihood of occurring such as: Executing Capital Projects during a Turnaround and having an outcome that is less than desirable. So many […]
Without exception, capital projects undertaken today call for comprehensive planning and closely managed project control. Project Planning and Cost Control have never been more important. An individual’s capacity to deal with change is a must in a rapidly changing world, and the effective use of management practices can contribute to an individual’s ability to effectively […]
Major Maintenance – work commonly called “Pitstops” or “Squats” – can be forgotten in the hectic world of Turnarounds and Routine Maintenance, so how do you judge the readiness and whether you are doing the right work? Pitstops or Squats are normally smaller events in size and duration that fall between doing everyday routine maintenance […]
The first two articles of this series provided a methodical approach to identifying a chloride problem in a hydroprocessing unit, determining the size of the problem, and narrowing it down to a likely source or sources. This final article addresses approaches to dealing with various sources. Step 4 – Managing the Chlorides Now that you […]
The first article of this series introduced the symptoms of a chloride problem in a hydroprocessing unit. In this article, we will explore how to interpret the symptoms by determining how much chloride-containing material we are looking for and identifying the possible or likely source(s) for this amount of material, embodied in Steps 2 and […]
Introduction This series of three articles explores the impacts chlorides may have on hydroprocessing units (hydrotreaters and hydrocrackers). It provides a methodical approach to identifying the typical effects that point toward chlorides, the sources of chlorides in process feed streams, chloride-induced failure mechanisms, methods for identifying chlorides, strategies for chloride control, and a step-by-step process […]
