Cold flow properties are of particular concern with middle distillate fuels because they contain straight and branched chain hydrocarbons (paraffin waxes) that become solid at ambient winter conditions in cold climates. At sufficiently low temperatures, fuels with wax compounds will start to crystallize and impact the flow characteristics of the fuel. Three primary fuel specifications are used to minimize supply problems in cold climates including cloud point, pour point and cold filter plugging point.
Elessent offers IsoTherming® dewaxing technology for the improvement of cold flow properties for the production of low and ultra low sulfur diesel. The technology will be tailored to meet the specific needs of the refiner by proper selection of catalyst systems and operating conditions.
