ABSTRACT:
In a lube oil dewaxing plant in which waxy lube oil is firstly conditioned to promote wax crystallization, such as by adding an oil solvent and chilling the resulting admixture, and then filtered in at least one rotary drum filter (213), the filter includes at least one spray header (92') including a plurality of charge injectors (300) which inject charge by field emission into a field which is sprayed from orifices (246) in the underside of the header onto the filter drum (20). The injected charge has the effect of enhancing separation of haze from the lube oil in the rotary drum filter (213). The charge carrier fluid may for example be solvent-diluted waxy oil or oil solvent liquid alone.
