  • Method for on-line monitoring of wax crystallization
    Patent number: 8029661
    Abstract: 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.
