Title:
FORMING ASPHALT FRACTIONS FROM THREE-PRODUCT DEASPHALTING
Document Type and Number:
WIPO Patent Application WO/2019/014196
Kind Code:
A8
Abstract:
Systems and methods are provided for using a three-product deasphalter to produce advantageous combinations of deasphalted oil, resin, and rock. The desaphalted oil, resin, and rock can then be further combined, optionally with other vacuum gas oil fractions produced during the distillation that generated the feed to the three-product deasphalter, to produce a product slate of improved quality while also maintaining the quality of the resulting asphalt product and reducing or minimizing the amount of lower value products generated. The additional "resin" product from the three product deasphalter can be generated by sequential deasphalting, by using a resin settler to separate resin from the deasphalted oil, or by any other convenient method.
