  • Patent number: 10343111
    Abstract: A method for disposing of excess sulfur dioxide in a flue gas from thermal oxidation of an acid gas stream including hydrogen sulfide recovered from a rich amine solution of an amine plant servicing at least one well head, includes cooling the flue gas to about 300 to about 650 degrees Fahrenheit, injecting a dry sorbent into the flue gas after the step of cooling the flue gas, reacting the dry sorbent after the step of injection, with the sulfur dioxide of the flue gas for sufficient time for formation of reaction byproduct and treated gas, and separating the reaction byproduct from the treated gas. Examples of the dry sorbent include calcium hydroxide, sodium bicarbonate, and trona, as well as magnesium hydroxide and sodium carbonate, and combinations.

  • Publication number: 20170173516
    Abstract: The system and method for preventing air leakage from the process side to the bearing side of a mill. The system includes a labyrinth seal ring comprising a series of knives defining first and second labyrinth paths from an air inlet to the process side and the bearing side of the system, respectively. The differences in the two paths such as provided by the number of knives used in each path creates a differential pressure drop which biases air from the air inlet to the process side. The labyrinth seal thus provides a reliable and superior method for reducing the potential for particulate in the process side of the mill from damaging the bearing system.

  • Patent number: 7798749
    Abstract: An improved pneumatic particulate conveyance system including a particulate diffuser plate is disclosed. The assembly includes a pipeline with one or more particulate inlets for introducing solid particulates to a prime mover, wherein the pipeline has at least one particulate diffuser plate located within the pipeline. The particulate diffuser plate has a length which runs parallel to the prime mover and occludes at least a portion of a particulate inlet so as to increase the surface area exposed to the conveying air, thus resulting in a more efficient momentum transfer to the particulate. The plate used in the assembly further includes an arcuate trailing edge so as to encourage more particulate falling into the middle (i.e., the higher velocity portion of the profile) of the prime mover.

  • Publication number: 20080178953
    Abstract: An improved abrasion resistant rotor assembly and valve and system related thereto is disclosed. The assembly includes a rotor body defining an annular opening which surrounds a drive shaft and a plurality of vanes radially extending from the rotor body. The rotor is made up of a unitary ceramic component, such as silicon carbide. The valve also includes a body for defining a bore that receives the rotor assembly, where the body bore is likewise comprised of a hardened ceramic material. This valve may thus be used to convey abrasive particulate in an efficient manner from a supply container to a pressured line for further processing or disposal.
