Description	Often the most cost effective way of enhancing mass transfer through improved mixing and settling of droplets in liquid-liquid extraction applied to lube systems is by way of using internals (packings). Although, such retrofits are generally performed to increase capacity, they also have been used to increase separation efficiency. Liquid extraction quite often proves to be an economical means of effecting a component separation. Packing material promotes mass transfer between the continuous and dispersed phases by forcing the phases to pass through interstices of the packings causing the dispersed phase droplets to follow a tortuous path through the packed bed. Most of the investigations in this direction have been carried out with respect to liquid and gas loadings. Commercial considerations have been the drivers to force the refineries and chemical plants to adopt new packings. However, there is room for carrying out R&D studies with respect to packings vis-à-vis lube extraction. An attempt has been made to initiate studies with relatively new generation packing, namely berl saddle, applied in lube systems, using N-methylpyrrolidone and comparing the findings with a standard conventionally employed packing (i.e., raschig rings). Preliminary studies indicate that the berl saddle performs better as compared to rasching rings in lube feed range (interneutral) taken from present studies.
