Abstract:
A method of producing fuel from CO2 comprising introducing natural gas, steam, and recovered CO2 to a reformer to produce unshifted syngas characterized by a molar ratio of hydrogen to carbon monoxide of from about 1.7:1 to about 2.5:1; introducing the unshifted syngas to a water gas shift unit to produce a shifted syngas, wherein an amount of CO2 in the shifted syngas is greater than in the unshifted syngas; separating the CO2 from the shifted syngas to produce recycle CO2 and a hydrogen-enriched syngas; recycling the recycle CO2 to the reformer, introducing the unshifted syngas to a Fischer-Tropsch (FT) unit to produce an FT product, FT water, and FT tail gas, wherein the FT product comprises FT liquids and FT wax; and separating the FT liquids from the FT product to produce a fuel.
Abstract:
A method for operating a natural gas liquids processing (NGL) system, the system being selectively configured in either an ethane rejection configuration or an ethane recovery configuration, the method comprising, when the NGL system is in the ethane rejection configuration, collecting a reboiler bottom stream that, in the ethane rejection configuration, includes ethane in an amount of less than 5% by volume, and when the NGL system is in the ethane recovery configuration, collecting a reboiler bottom stream that, in the ethane recovery configuration, includes ethane in an amount of at least about 30% by volume.
Abstract:
The various processes of a plant may be segmented into separate process blocks, which may be interconnected using fluid conduits and/or electrical connections. These process blocks may be directly connected, for example without an external piperack interconnecting process blocks. In some embodiments, each process block may be formed of one or more modules. The process-based nature of this modular approach, along with the optional lack of an external interconnecting piperack, may provide benefits over conventional modular plant design.
Abstract:
Plants, processes, and methods for reducing the H2S and CO2 contents of shale gasses from fields that produce shale gasses having varying H2S and CO2 contents are provided. Acid gas enters an absorber and is scrubbed using a lean physical solvent, producing a treated gas and a rich physical solvent. The H2S content of the treated gas is further reduced in an amine absorber, producing a pipeline gas and a semi-lean amine. The pipeline gas contains lower levels of H2S and CO2 than gas produced using a polishing bed. A physical solvent regeneration unit regenerates the lean physical solvent from the rich physical solvent for feeding into the absorption unit. An amine regeneration unit regenerates the lean amine from the semi-lean amine for feeding into the amine absorber. Contemplated plants may further comprise a Claus Unit or a Redox unit for oxidizing H2S to elemental sulfur.
Abstract:
Electronic comparison methods are described for determining changes in a current design model with respect to an earlier model and analyzing the impact of the identified changes. The method includes associating a priority value with a set of modified component objects using one or more algorithms and presenting a subset of the set of component objects, each of which has a priority value greater than a threshold value.
Abstract:
A system for reducing SO2 emissions comprises a hydrogenation reactor, a tail gas cooler, a contact condenser, a hydrolysis reactor, and an absorber. The hydrogenation reactor is configured to receive a Claus tail gas and convert at least a portion of SO2 in the Claus tail gas to H2S to produce a hydrogenated Claus tail gas stream. The hydrolysis reactor is configured to convert at least a portion of COS to H2S. The absorber comprises an amine-based solvent and is configured to absorb at least a portion of the H2S and recycle the H2S to the Claus plant.
Abstract:
Advanced oxygen enrichment technologies for Claus plants are presented that provide an oxygen rich gas stream to the Claus burner of the thermal stage and one or more oxygen rich bypass gas streams to at least one of the catalytic stages to so increase the capacity of the plant while reducing the amount of recycle gases needed for flame temperature moderation.
Abstract:
Separating propane and heavier hydrocarbons from a feed stream by cooling the feed stream, introducing the chilled feed stream into a feed stream separation unit, pumping the separator bottom stream, introducing the pressurized separator bottom stream into a stripper column, reducing the pressure of the separator overhead stream, introducing the letdown separator overhead stream into an absorber column, collecting a stripper overhead stream from the stripper column, chilling the stripper overhead stream, reducing the pressure of the chilled stripper overhead stream, introducing the letdown stripper overhead stream into the absorber column, collecting an absorber bottom stream, pumping the absorber bottom stream, heating the absorber bottom stream, introducing the heated absorber bottom stream into the stripper column, and collecting the stripper bottom stream from the stripper column. The stripper column bottom stream includes the propane and heavier hydrocarbons and less than about 2.0% of ethane by volume.
Abstract:
A system for analyzing a coking system comprises a coking system comprising a first coke drum and a second coke drum, and a user device communicatively coupled to a hardware implemented analysis engine. The coking system configured to collect and transmit coke drum data to the hardware implemented analysis engine. The hardware implemented analysis engine is configured to: receive an estimation of an altered life span of the first coke drum relative to a design life span of the first coke drum, analyze an effect of adding an additional coke drum to the coking system based on the altered life span, and provide a result item related to the analysis to the user device. The estimation of the altered life span is based on the coke drum data.
