Abstract: A method for selecting one or more crude oils from a plurality of crude oils. In some embodiments, a plurality of scenarios may be generated, each scenario comprising a plurality of values corresponding, respectively, to a plurality of uncertain parameters, the plurality of uncertain parameters comprising at least one uncertain parameter relating to a quality of a crude oil of the plurality of crude oils. In some embodiments, a stochastic programming model may be solved to obtain a solution that optimizes an objective function, and one or more crude oils may be procured based on respective procurement amounts in the solution of the stochastic programming model. In some embodiments, a chance-constrained programming model may be solved to obtain a solution that optimizes an objective function, and a plurality of feedstocks may be blended into a final product based on the solution of the chance-constrained programming model.

Abstract: Systems and methods for the separation and capture of carbon dioxide from water are generally described. In some embodiments, a vapor stream containing carbon dioxide and water is separated using a cascade of at least two flash drums. Additional flash steps may be incorporated to remove atmospheric gases, such as nitrogen and argon, from the feed. Carbon dioxide may be condensed and pressurized at purities suitable for pipeline transport and eventual storage in geological formations. In addition, water may be recovered at high purity. In some embodiments, fuel cells may be used in combination with fuel reforming or gasification to produce syngas. Certain aspects of the invention involve innovations related to the combined reforming and fuel cell process, that, in certain embodiments, do not depend upon water and carbon dioxide separation.
