Can Oversized Separators Do More Harm Than Good?
Large separators are often designed to meet the requirements of higher-capacity facilities. But these vessels bring with them consequences on the operating conditions over the full life cycle of a field.
Clear Plans, Designs Necessary for Effective Three-Phase Separation
Operators must take a more practical and less theoretical approach to the design and construction of three-phase separators, with an honest assessment of their separation needs.
Savvy Separator: The Ghosts of Separators Past, Present, and Future
Lessons learned by the members of the SPE Separations Technology Technical Section, representing more than 250 years' experience, are presented so that the same mistakes are not repeated in the future.
STTS To Hold Special Session on Gas Scrubber Design at ATCE
"Gas Scrubber Design and Validation for Robust Separation Duty" is the title of a special session planned by the Separations Technology Technical Section.
Quantifying Separation Performance Taking Bothamley’s Work to the Next Level
Mark Bothamley's series quantifying separation performance in the August-December 2013 issues represents a significant addition to the literature in two-phase separator design. Ken Arnold proposes additional areas of study to take our knowledge even further.
Gas/Liquids Separators—Quantifying Separation Performance—Part 2
In this second article of a three-part series, methods for improved quantification of operating performances of the gas gravity separation, the mist extraction, and the liquid gravity separation sections of gas/liquid separators are discussed.
Gas/Liquid Separators: Quantifying Separation Performance—Part 1
Many two-phase and three-phase separators in the oil and gas industry continue to underperform. This article explores the weaknesses in different sizing methodologies and proposes manageable approaches to quantifying each.
Webinar Highlights Effects of Foam in Separators
In an SPE webinar, “Foaming in Separators: Handling and Operation,” Wally Georgie, principal consultant at Maxoil Solutions, presented an overview of foam generation and how the design of processes and chemical management can exacerbate its detrimental effects in separators.
New Method To Estimate Surface-Separator Optimum Operating Pressures
Setting optimal surface separation pressures are crucial for maximizing the surface liquid production from the wellstream feed. Where separator tests are not available, empirical calculations are often used, but with limitations. A method suitable across many conditions is proposed.
Selected Reading for Facilities Engineers; ATCE Reveals PFC Performance Shortfalls
Recent activities around career planning for facilities engineers led me to a list of "must read" books. The recent ATCE generated two revelations. As an industry, we do a poor job of managing major capital projects, and we do not know how to design separators.
Challenges in Heavy Oil Processing
At the end of the day, when you are working with heavy oil, the question is how to design your system, including both the layout and the functional aspects of various equipment.
Computational Fluid Dynamics-Based Study of an Oilfield Separator—Part I: A Realistic Simulation
A realistic computational fluid dynamics (CFD) simulation of a field three-phase separator has been developed. Further, a useful approach to estimating the particle size distribution in oilfield separators was developed. The predicted separation efficiencies are consistent with oilfield experience.
Importance of Flow Conditioning for Separator Performance
Fluid flows in separation vessels are key to effective performance. The flow distributions are affected by the vessel, the configuration of its internals, and the layout of the upstream piping connecting to the vessel’s inlet nozzle.
Highlights in Projects, Facilities, and Construction
ATCE included expanded content for project, facilities and construction professionals. Panels discussed our performance in managing megaprojects and our challenges in designing separation equipment. Two technical paper sessions were also included.
