SHELL DEWAXING TECHNOLOGIES FOR DISTILLATE APPLICATIONS

摘要

In the last decade improving the cold flow properties of distillatesnin a selective and cost efficient way has gained increasing importance.nIn addition to providing a product in the specified cold flownproperty range, refineries apply cold flow improvement processes tonavoid using cold flow additives, to reduce their kerosene blendingnrequirements, to upgrade heavier feedstocks with higher cloud and/ornpour points, and to create room in the distillate blending pool fornheavier feeds. The growing interest in cold flow improvement technologiesnstems from increasingly stringent engine specifications,nprocessing of more paraffinic crudes, and selling the products at marketsnwith demanding cold flow property specifications.
