Composite filter aids for cleanup of additives
This article examines the properties of composite filter aids in additive cleanup using two- and three-component filter aid composites based on perlite, kieselguhr, diatomite, asbestos, and wood flour. Filtration tests were run on naphtha solutions of the additive zinc dialkyldithiophosphate. The laboratory studies indicate that composites of perlite and kieselguhr with fibrous materials (wood flour or asbestos) show great promise for the removal of solid contaminants from the zinc disalkydithiophosphate additive. The advantages of the filter aid composite based on perlite, kieselguhr, and wood flour in comparison with the two-component composites are the higher filtration rate (by 26%) and the smaller losses of additive (by a factor of 2.1) and isobutyl alcohol (by a factor of 1.6). It is demonstrated that the filtration rate with the three components is 50-60% higher than with the composite of perlite with kieselguhr. The filtration of the zinc dialkyldithiophosphate additive using the composite filter aid based on perlite, kieselguhr, and wood flour, has been adopted at the Volgograd Petroleum Refinery. Includes 2 tables.
