    Abstract: A process for treating a gas comprising hydrogen suilfide and carbon dioxide by contacting the gas with a scrub solution comprising ammonium sulfite and ammonium bisulfite in a first contact zone to produce ammonium thiosulfate. The scrub solution can be formed in a second contact zone by contacting ammonia and hydrogen sulfide with an aqueous solution. The oxidation potential of the first contact zone effluent liquid can be controlled by modulating the amount of sulfur dioxide supplied to the second contact zone. Alternatively, the sulfite concentration of the first contact zone effluent can be measured with an infrared analyzer and the amount of sulfur dioxide supplied to the second contact zone modulated in response. Additionally, the amount of ammonia supplied to the second contact zone can be modulated in response to the pH in the second contact zone. The process can further comprise a solvent scrubber to remove carbon dioxide from the first contact zone overhead gas. A third contact zone can be included in the process to separate the hydrogen sulfite from the carbon dioxide in the solvent regenerator overhead gas.

    Abstract: An optical device having a variable index of refraction across its surface includes a light transmissive material with a plurality of regions in the light transmissive material. Each region has an index of refraction which is different from the remainder of the material. The regions may be arranged in the surface of the material such that the density of the regions on the surface varies across the surface. Each region may be a bore, including a hole that extends through the light transmissive material. Variations in the density of the regions or bores as well as the depth and shape of the bores may be utilized to create variations of the refractive index within the light transmissive material.

    Abstract: An imaging device (10) has a plurality of unit cells that contribute to forming an image of a scene. The imaging device includes a layer of semiconductor material (16), for example silicon, that has low noise photogate charge-mode readout circuitry (20, 21, 26, 28) (e.g., CCD or CMOS readout circuitry and structures) that is disposed upon a first surface (18) of the layer. A second, opposing surface of the layer is a radiation admitting surface of the layer. The layer has a bandgap selected for absorbing electromagnetic radiation having wavelengths shorter than about one micrometer and for generating charge carriers from the absorbed radiation. The generated charge carriers are collected by the photogate charge-mode readout circuitry. A thermal sensing element (22) is disposed above and is thermally isolated from the first surface of the layer. The thermal sensing element may be, by example, one of a bolometer element, a pyroelectric element, or a thermopile element. A layer (12) of narrower bandgap semiconductor material can also be employed with this invention, wherein the layer of narrower bandgap semiconductor material (such as InGaAs or HgCdTe) is atomically bonded to the second surface along a heterojunction interface that is continuous or apertured across the second surface. The bonded layer is used to absorb NIR and visible light.

    Abstract: Carbonaceous materials are thermally upgraded in a pressurized steam environment to remove moisture and other byproducts. A variety of water/solid separation devices may be employed in a process vessel to maximize moisture removal from the upgraded charge. Heating media inlet nozzles and process chamber vents are strategically positioned at the process vessel wall to minimize short circuiting of heating media to vessel outlet vents and to continuously separate hot water removed from the charge and condensed steam, such that the upgraded material removed from the process vessel is not discharged with accompanying free moisture. After upgrading, the charge may be rehydrated to improve its stability during shipping and storage.
