Title: "Modern Sieve Trays for
Liquid-Liquid Extraction"

Abstract:
Sieve trays continue for find a role in modern liquid-liquid extractions
where static devices are specified for various niches in the petroleum and
chemical process industry.
There are several equipment features that have demonstrated that can
improve the reliability and performance of sieve extractor trays. These
include: extruded orifice holes for deck perforations, downcomer restrictors, structural
truss orientation and using multiple downcomers for large diameter units.
Properly designed inlet devices and liquid-liquid coalescers are also important
considerations for achieving good performance in these applications.
This paper provides examples of recent industrial experience involving
sieve trays equipped with special features.
