摘要:
The present invention pertains to a pervaporation membrane process for the separation of high octane fuel components from a gasoline feed stream comprising feeding a mixed phase vapor-liquid feed to a cyclone separation means to separate the liquid from the vapor, then sending the saturated vapor to the membrane, thereby extending the useful life of the membrane.

摘要:
The present invention relates to an improved delayed coking process. A coker feed, such as a vacuum resid, is treated with (i) a metal-containing agent and (ii) an oxidizing agent. The feed is treated with the oxidizing agent at an oxidizing temperature. The oxidized feed is then pre-heated to coking temperatures and conducted to a coking vessel for a coking time to allow volatiles to evolve and to produce a substantially free-flowing coke. A metals-containing composition is added to the feed at at least one of the following points in the process: prior to the heating of the feed to coking temperatures, during such heating, and/or after such heating.
摘要:
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.
