Abstract
This invention relates to a process of producing an upgraded product stream from the products of a resid visbreaking process to produce an improved feedstream for refinery and petrochemical hydrocarbon conversion units. This process utilizes an ultrafiltration process for upgrading select visbreaking process product streams to produce a conversion unit feedstream with improved properties for maximizing the conversion unit's throughput, total conversion, run-time, and overall product value.
