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.
