摘要:
This invention relates to a process for producing a product stream with improved reduction of Conradson Carbon Residue (“CCR”) and a reduced average boiling point from a heavy hydrocarbon feedstream utilizing a high-pressure, low-energy separation process. The invention may be utilized to reduce the CCR content and reduce the average boiling point in heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, bitumen, oil from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams. This invention also results in a process with an improved CCR separation efficiency while maintaining permeate flux rates.

摘要:
The present invention provides methods and systems for discretized, combinatorial processing of regions of a substrate such as for the discovery, implementation, optimization, and qualification of new materials, processes, and process sequence integration schemes used in integrated circuit fabrication. A substrate having an array of differentially processed regions thereon is processed by delivering materials to or modifying regions of the substrate.
摘要:
Parallel semi-continuous or continuous reactors are disclosed. The parallel reactors preferably comprise four or more reaction vessels. The reaction vessels are preferably small volume reaction vessels, preferably pressure reaction vessels, and/or preferably integral with a common reactor block. The reaction vessels can comprise shaft-driven stirrers. At least two, preferably at least three or at least four liquid feed lines can provide selective fluid communication between each of the reaction vessels and one or more liquid reagent sources. Additional features, suitable in connection with parallel reactors or with single reaction vessels are also disclosed.
