Separation/treating
This article is the second of a two-part series on produced-water management in the Gulf of Mexico and covers four themes: equipment, process configuration, operations, and effluent quality.
Sharing state-of-the-art design and troubleshooting methods, the workshop identified future separation needs and gap statements and proposed how to close the gaps.
The pitfalls of utilizing an existing vessel without proper review are highlighted.

This paper presents details of the retrofit scrubber design and shows the importance of using high-efficiency separation internals. -
An operator in the western Gulf of Thailand retrofit two partial-processing water-management systems on mobile-offshore-production-unit platforms for bulk removal and treatment of produced water. Water debottlenecking increased oil production by 80% and reduced the infield transfer volume by 62%. Th

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.

This article highlights some of the code and registration issues the Savvy Separator engineer encounters when retrofitting a vessel with internals to improve or restore the process performance of the separator.

Part 2 of this two-part series presents a new methodology for sizing and rating three-phase separators based on quantifying the actual mechanisms and physics that govern separation performance. An example illustrates the calculations needed to achieve the specified outlet fluid qualities.
-
By understanding the factors involved in oil droplet coalescence, the Savvy Separator engineer can assess the operational/chemical factors in the treatment system that are affecting droplet growth and make adjustments to enhance coalescence rates.
-
Operators are increasingly using existing offshore infrastructure for asset life extension, and developing new marginal stranded fields rather than develop new large greenfields. Subsea processing is an enabling technology in this goal.

Magnetic nanoparticles (MNPs) is a promising way to remove dispersed oil from produced water. In this study, the authors investigated the optimal operating conditions for MNPs and the mechanisms of MNP/oil attachments and magnetic separation.

A senior process engineer from TechnipFMC discusses the ways in which inadequate design and sizing methodologies can lead to poor scrubber performance.
