  • Process For The Production Of Hydrogen/Carbon Monoxide
    Publication number: 20130009099
    Abstract: The present invention provides for an energy efficient process of producing hydrogen/carbon monoxide gas mixtures from one or more hydrocarbon gas streams treated in a syngas producing unit by utilizing a carbon dioxide removal unit that contains sorbent beds in which a magnesium based sorbent is transported and cycled between different beds for sorption and desorption of carbon dioxide. The carbon dioxide recovered during the process is recovered at high temperature and high pressure therefore allowing for at least a portion of the carbon dioxide stream to be recycled for further treatment with little or no compression of the stream.

  • Method for Melting a Batch of Raw Materials by a Crown Burner
    Publication number: 20120324951
    Abstract: The invention concerns a method for melting a composition of raw materials including introducing the composition in an oven to form a layer (2) at the surface of the molten pool (4). An oxycombustion burner (10) is arranged above the pool and directed towards the composition layer (2) to produce a melting front (3). Parameters of the burner are adjusted to produce a large covering flame (12) causing an essentially radiation-based thermal transfer. Additionally, a plane containing a longitudinal section of the flame (Z-Z) and a horizontal direction perpendicular to the axis of the oven (X-X) intersects the melting front (3) at a height (h) included ranging between one third and half of the thickness of the composition (e). Such a method provides for a stable operation of the oven and is particularly adapted to a large-capacity oven.
