Abstract
This invention relates to a process of producing an upgraded product stream from steam cracker tar feedstream suitable for use in refinery or chemical plant processes or for utilization in fuel oil sales or blending. This process utilizes an ultrafiltration process for separating the steam cracker tar constituents resulting in a high recovery, low-energy process with improved separation and product properties.
