Use of copolymer of ethylene with vinyl acetate as a promoter in oil dewaxing

Control of n-alkanes crystallization by ethylene–vinyl acetate copolymers

“…Among the various additives that have been developed for the control of paraffin crystallization in order to improve the behavior of petroleum distillates at low temperatures [26,27], ethylene-vinyl acetate copolymers (EVA) show good efficiency in diesel oil [13,14,28]. The crystals formed in the presence of EVA are much smaller and more numerous, and they exhibit a more compact habit [23].…”
