Title: Separation and/or sequestration apparatus and methods

Abstract

Apparatus for separating CO.sub.2 from an electrolyte solution are provided. Example apparatus can include: a vessel defining an interior volume and configured to house an electrolyte solution; an input conduit in fluid communication with the interior volume; an output conduit in fluid communication with the interior volume; an exhaust conduit in fluid communication with the interior volume; and an anode located within the interior volume. Other example apparatus can include: an elongated vessel having two regions; an input conduit extending outwardly from the one region; an output conduit extending outwardly from the other region; an exhaust conduit in fluid communication with the one region; and an anode located within the one region. Methods for separating CO.sub.2 from an electrolyte solution are provided. Example methods can include: providing a CO.sub.2 rich electrolyte solution to a vessel containing an anode; and distributing hydrogen from the anode to acidify the electrolyte solution.

  • In one embodiment, a CO.sub.2 leak detection instrument detects leaks from a site (e.g., a CO.sub.2 sequestration facility) using rapid concentration measurements of CO.sub.2, O.sub.2 and optionally water concentration that are achieved, for example, using laser spectroscopy (e.g. direct absorption laser spectroscopy). Water vapor in the sample gas may not be removed, or only partially removed. The sample gas may be collected using a multiplexed inlet assembly from a plurality of locations. CO.sub.2 and O.sub.2 concentrations may be corrected based on the water concentration. A resulting dataset of the CO.sub.2 and O.sub.2 concentrations is analyzed over time intervals to detectmore » any changes in CO.sub.2 concentration that are not anti-correlated with O.sub.2 concentration, and to identify a potential CO.sub.2 leak in response thereto. The analysis may include determining eddy covariance flux measurements of sub-surface potential carbon.« less
  • Sample component separation apparatus and methods are described. An exemplary sample component separation apparatus includes a separation channel having a turn portion configured to reduce band-broadening caused by passage of a sample through the turn portion. To reduce band broadening caused by passage of a sample through a turn portion, the turn portion may be constructed and arranged to have a sample transport characteristic that is different from the corresponding sample transport characteristic of a substantially straight portion of the separation channel. For example, the turn portion may be configured with an effective channel width that is smaller than themore » effective channel widths of the substantially straight portion of the separation channel. The actual channel width of the turn portion may be smaller than the channel widths of the substantially straight portion; the effective channel width of the turn portion may be reduced by placing one or more sample transport barriers or constrictions in the turn portion of the channel. Alternatively, the sample velocity through the turn portion may be controlled so as to reduce band broadening. For example, sample transport barriers may be disposed in the turn portion so that sample components of a given band travel through the turn portion at substantially the same effective rate, whereby the band orientation remains substantially aligned along radial directions characteristic of the turn portion. Other a sample transport characteristics, such as electrical resistance or fluid flow resistance, of the turn portion may be adapted to reduce band broadening caused by passage of the sample through the turn portion.« less
  • This patent describes a method of selectively detecting an analyte in a gaseous mixture by a chemical sensor. It comprises pumping ambient air through a chemical filter so as to purify the air from these constituents to which the sensor is responsive, pumping the purified air through a sorbent-containing tube and through the sensor, drawing a portion of the gaseous mixture into a sample port, flushing the portion with purified air from the sample port into the sorbent tube, through an inlet end of the tube, directing analyte-containing eluent from the sorbent tube into the sensor, and preventing at leastmore » one other mixture component to which the sensor is responsive from reaching the sensor, the sorbent having a different retentivity for the analyte than for another component of the gaseous mixture to which the sensor is responsive.« less
  • A method and apparatus are described, including liquid-vapor contact and mass transfer arrangements involving the injection of liquid into vapor in combination with liquid-vapor separator arrangements of the rotating type. The liquid-vapor separator arrangements may be used alone and the combination may be used as a single unit or as a number of units connected in series relation to effect stripping scrubbing or rectification processes. The apparatus has utility in processes involving the exchange of mass and heat between liquid and vapor phases, including processes involving scrubbing and stripping operations. (16 claims)
  • Downhole fluid injection systems are provided that can include a first well extending into a geological formation, and a fluid injector assembly located within the well. The fluid injector assembly can be configured to inject a liquid CO 2/H 2O-emulsion into the surrounding geological formation. CO 2 sequestration methods are provided that can include exposing a geological formation to a liquid CO 2/H 2O-emulsion to sequester at least a portion of the CO 2 from the emulsion within the formation. Hydrocarbon material recovery methods are provided that can include exposing a liquid CO 2/H 2O-emulsion to a geological formation havingmore » the hydrocarbon material therein. The methods can include recovering at least a portion of the hydrocarbon material from the formation.« less
