The determination of wax crystal particle size and population is used to monitor the performance of wax crystallizers used in lubricant oil processing using solvent dewaxing. The wax crystal particle size is monitored using online measurements. The information obtained from on-line monitoring is then used to control crystallization in the dewaxing equipment in order to optimize performance of the dewaxing units.

Method for on-line monitoring of wax crystallization

The invention relates to a process for preparing lube oil basestocks from lube oil boiling range feeds. More particularly, the present invention is directed toward a process wherein a wax containing feed is solvent dewaxed to produce at least a partially dewaxed lube oil boiling range stream, which is hydrodewaxed to produce a first lube basestock. The first lube basestock is added to an independently selected second lube basestock and additives to make a lubricating oil.

Method for making a lubricating oil with improved low temperature properties

All catalytic process for producing white oils is provided. More particularly, medicinal grade white oils are produced from a process including hydrotreating and/or hydrocracking, catalytic dewaxing followed by hydrofinishing to produce a medicinal white oil.
