Abstract: Methods and systems for oxyfuel based low emission power generation in hydrocarbon recovery processes are provided. One system includes a plenum and is configured to encourage post-combustor conversion of gaseous components such that a desired chemical state is achieved. Another system includes a steam reformer for reforming a control fuel stream to generate a reformed control fuel stream characterized by an increase in hydrogen, as compared to the control fuel stream.

Abstract: A coupling assembly for sealing an interface between a pipe and a sump wall, the assembly comprising; a sleeve (21) configured to be inserted in an aperture in a sump wall (20) and having a bore suitable for receiving a collar (22), the sleeve (21) having in diametrical cross section along its inner surface one or more circumferentially arranged, longitudinally extending undulations (21a); a collar (22) configured to be received between the sleeve (21) and the pipe P, being fusible to the pipe P and having a stepped internal diameter (22a) for receiving a swaging bung (23), a swaging bung (23) configured to be received in the stepped portion (22a) of the internal diameter of the collar (22) and configured to receive a pipe P; at least one washer (24a, 24b) having a diameter sized to fit the outside diameter of the sleeve (21); and a quantity of matting (25) comprising a material which is leak tight bondable to the material of the sump wall (20).

Abstract: A grid assembly for use with an imaging cassette. The grid assembly includes an anti-scatter grid having a length and opposing first and second ends; first and second transport members disposed proximate the first and second ends, respectively, of the grid; at least one first roller disposed at the first end of the grid; at least one second roller disposed at the second end of the grid; and a pair of support members disposed substantially perpendicular to the length and proximate the opposing ends of the grid in spaced relationship to form a slot having an opening proximate one side of the grid adapted to removably slidably receive the imaging cassette adjacent the grid.

Abstract: A grid assembly for use with an imaging cassette, for example, a computed radiography cassette, particularly an elongated radiography cassette. The grid assembly includes: an anti-scatter grid; a radiographically translucent enclosure housing the anti-scatter grid and having two ends; a transport member disposed proximate a first end of the enclosure; at least one roller disposed proximate a second end of the enclosure; and a receiving member attached to the enclosure and adapted to removably receive and secure the imaging cassette.
