Potential Operating Strategies & Considerations – An SME Perspective

refinery_optimiztion
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 your business partner, Becht is committed to assisting you with Subject Matter Expert (SME) experienced-based solutions and guidance. We have extensive owner/operator expertise including previous industry downturns.  Below is a punch list of considerations for the current market. If you are considering a crude rate reduction & corresponding turndown or shut down of process and utility units:What are the challenges / limitations / risk to minimum rate capacities?Can we reliably shut down one train on dual train systems?How do we mothball / maintain equipment to prevent future degraded status?Should we use this opportunity to perform needed maintenance? What...

Design Rules for the Prevention of Failures by Fatigue in ASME B31 and ASME III

What_Markl_Did
A Seminal Publication...In the history of the ASME B31 pressure piping codes (and ASME III Div.1), there is a handful of publications that have set the design rules for generations to come. One such publication is A.R.C. Markl’s “Piping-Flexibility Analysis”, Transactions of the ASME, February 1955.Other publications by Markl and his associates are listed here, but the 1955 publication is where the design rules were fully set and explained:Fatigue Tests of Welding Elbows vs. Miter Bends - A.R.C. Markl, 1947Fatigue Tests of Flanged Assemblies - A.R.C. Markl and H.H. George, 1949Fatigue Tests of Piping Components - A.R.C. Markl, 1951Piping Flexibility Analysis - A.R.C. Markl, 1953Why Branch Connections Fail - A.R.C. Markl, E.C. Rodabaugh and H.H. George, 1955Effects of Internal Pressure on Flexibility - E.C. Rodabaugh and H.H. George, 1956Balanced Quality as a means of Attaining Maximum Economic Safety for Critical Piping - A.R.C. Markl, 1957Fabricated Pressure Piping as Related to Nuclear...

Are Your Capital Project and Turnaround Groups Aligned?

Turnaround-groups-aligned_Becht-Engineering
Here’s How To Get On TrackThere 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 of our projects require some amount of outage work to at least perform tie-ins.  Many projects may even require significant work when the unit is shut down.  This tends to drive up the cost of labor and drive down productivity.Most of the industry, including the sites that I have worked with over the years, have embraced the need for a unified TA/Construction effort during the turnaround window.  This has significantly reduced the need to have two organizations competing for a finite resource of safe work permits, real estate, etc.  Having one team planning a combined workload and...

Reaching Out Internally and Externally for Operational Excellence Improvement

operational-excellenc_20200223-162355_1
One of the major issues we see when we go into some plants to do a maintenance or reliability assessment Is that the plant is an isolated island even in a multi plant enterprise. Sharing of ideas across sites is discouraged or forbidden by corporate culture or site management and there are no enterprise scorecards comparing site to site KPI’s. These sites rarely participate in external industry organizations, take external training courses or collaborate with personnel at other sites. One might ask how these organizations keep up with best practice, solve problems common to most refiners and train their staff. The simple answer is they don’t. Without some level of benchmarking and external communication it is very difficult to determine where you are relative to industry peers and how to improve. This blog discusses how one organization developed programs to reach out internally and externally - even extending beyond our industry...
