Abstract: Methods are provided for the production of nitrogen, hydrogen, and carbon dioxide from an exhaust gas. Exhaust gas from combustion in a fuel rich (or reducing) atmosphere is primarily composed of CO2, CO, N2, H2O, and H2. CO may be converted to CO2 and H2 via the water gas shift reaction. Carbon dioxide may then be effectively separated from nitrogen and hydrogen to produce a carbon dioxide stream and a nitrogen/hydrogen stream. The nitrogen/hydrogen stream may then be effectively separated to produce a high purity nitrogen stream and a high purity hydrogen stream. The process may be done in any order, such as separating the nitrogen first or the carbon dioxide first.

Abstract: Methods are provided for predicting the properties of an asphalt fraction that contains two or more asphalt components based on measurements of the viscosity versus temperature profile for the components of the asphalt fraction. The viscosity versus temperature profile for each component can be used to determine characteristic (such as limiting) values for the viscosity and temperature for a component. Based on this ability to determine characteristic values for an asphalt blend based on the properties of individual blend components, appropriate blends of asphalts can be selected in order to arrive at an asphalt blend with desired properties.

Abstract: Systems and methods are provided for determining a content of a hydrocarbon or other compound, such as a C3 to C7 hydrocarbon, in a condensed steam sample. Cooled steam condensate can be flowed through a sample chamber including an inner overflow tube. When the flow stops, water can be drained from the sample chamber, and then the sample chamber can be opened to allow fluid communication with a vapor chamber above the sample chamber. This can allow hydrocarbons in the condensed steam (and/or other gas) to be transferred from the sample chamber into the vapor chamber. The vapor chamber can then be isolated from the sample chamber. At least a portion of the content of the vapor chamber can then be passed to a detection volume, such as the characterization cell for a gas chromatography system.

Abstract: Diesel fuel compositions are provided that have unexpectedly beneficial cold flow properties. Methods for forming such diesel fuel compositions are also provided. The improved cold flow properties are achieved in part based on dewaxing of a distillate fraction of the composition. The improved cold flow properties are achieved further in part based on inclusion of a cold flow additive and fatty acid alkyl ester in the composition, such as fatty acid methyl ester.

Abstract: Methods and systems producing gasoline boiling range hydrocarbons from light paraffins are disclosed. Such methods may include exposing a paraffin-containing stream to a catalyst in a side riser of a fluid catalytic cracking reactor under effective conditions for dehydrogenating at least a portion of paraffins in the stream into olefins and thereby producing an olefin-containing stream, wherein the paraffin-containing stream comprises greater than 50 wt % isobutane; and alkylating olefins in the olefin-containing stream to produce a product stream comprising an alkylate fraction comprising hydrocarbons boiling between 100° F. and 400° F.

Abstract: Systems and methods are provided for integrating a fluidized coking process, optionally a coke gasification process, and processes for production of additional liquid products from the coking and/or gasification process. In some aspects, the integrated processes can allow for conversion of olefins generated during a fluidized coking process to form additional liquid products. Additionally or alternately, in some aspects the integrated processes can allow for separation of syngas from the flue gas/fuel gas generated by a gasifier integrated with a fluidized coking process. This syngas can then be used to form methanol, which can then be converted in a methanol conversion process to form heavier products. In such aspects, olefins generated during the fluidized coking process can be added to the methanol conversion process to improve the yield. Additionally, in various aspects, the off-gas from the integrated conversion process can be used as an additional paraffin feed that can be recycled to one of the heat integration conduits in the fluidized coker for additional generation of olefins. This can provide a further increase in liquid yields using a carbon source (C4− paraffins) that is conventionally viewed as a low value product from coking.
