In this eighth articles of the series, level settings and control in gravity separators are addressed.
Applying Subsea Fluid-Processing Technologies for Deepwater Operations
Subsea processing is an evolving technology in ultradeepwater development and has the potential to unlock a significant amount of hydrocarbon resources. In this paper, the authors have reviewed the application of subsea systems in 12 deepwater fields and discussed the significance of each.
Savvy Separator: Introduction to CFD for Separator Design
Why CFD should be part of your separator design? This goal of this goal is to allay any fears about CFD that you may have as a result of flashbacks to university class and a dizzying array of partial-differential equations.
Savvy Separator Series: The Effect of Shear on Produced Water Treatment
The sources and magnitude of shear and the effects on oil droplet size can have significant consequences for downstream separation equipment performance.
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.
Savvy Separator: Scrubber Debottlenecking
An underperforming scrubber that was suffering from too much oil carry-over is described along with options for debottlenecking and improving performance.
Savvy Separator: The Effect of Inlet Geometries on Flow Distribution
Efficient separation assumes uniform flow, but the reality of inlet geometries can invalidate this assumption, leading to separation problems and loss of separation efficiency.
Savvy Separator: Design of Cyclone Separators: Internals and Liquid Levels
Some internals components affect a separator's gas- and liquid-handling capability because of their effects on the liquid level. In this article, the interdependency of cyclonic inlets, cyclonic mist eliminators, and liquid level is highlighted.
Taking on the Technical Challenges of Sour Gas Processing
High H2S and CO2 content in natural gas pose significant challenges to processing equipment. This article explores the challenges of sulfur removal and high pressures in the presence of acid gas.
Topside Processing Plants Go Compact on FPSOs
The development of compact topside processing plants for floating, production, storage and offloading (FPSO) vessels is a growing industry trend that can reduce operating and capital expenditures over the life of the vessel, a researcher and scientist said recently.
Novel Leak Detection Method for Sulfur Recovery Unit Condensers
Tube leaks present in a water-cooled sulfur recovery unit (SRU) condenser can lead to a variety of process issues, including corrosion and the oxidative formation of acidic species. This work devised a novel method to verify such leaks within a SRU condenser.
Acoustic-Induced-Vibration Case Study for WDDM Onshore Facilities
In gas applications with high-pressure drops and/or high-velocity gas flow, acoustic-induced vibration (AIV) occurs when very high sound levels are propagated in piping. This can induce fatigue cracking of the pipe and potentially catastrophic pipe failure.
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.
Advancements in the Removal of Mercury From Crude Oil
Issues associated with mercury’s presence in hydrocarbon processing systems have become more apparent as deeper and hotter reservoirs (often with higher levels of mercury) were exploited, and with the low-temperature gas processing used for liquefied natural gas (LNG) and natural gas liquids.
Sulfate Removal—The Adoption of a Water Treatment Technology by the Oil and Gas Industry
The oil and gas industry is sometimes slow to adopt new technologies and other times quick to deploy a new approach. The decision whether to try something new weighs the perceived risks and rewards.
