  • Publication number: 20190317819
    Abstract: A computer-implemented method of enabling distributed computers to communicate more effectively in an enterprise that provides flexible approval notifications in an organization, wherein at least one of the distributed computers stores a graph database in which attributes regarding individuals of the organization are stored. The computer-implemented method includes receiving, at a server computer in the distributed computers, a request for a task to be performed, wherein the task requires approval by at least a first person in the organization who has authority to approve the request. The computer-implemented method also includes traversing, by the server computer, the graph database, to determine an identity of the first person, wherein traversing is performed based on criteria determined at least partially by information automatically extracted from the request.

  • Publication number: 20190309233
    Abstract: A solids discharge system (SDS) is configured to separate solids from product gas. The system includes a solids separation device and at least one solids transfer conduit configured to receive solids from the solids separation device. The solids transfer conduit is selectively partitioned into a plurality of compartments (or “sections”) along its length by isolation valves. A gas supply conduit and a gas discharge conduits are connected to one of the sections to facilitate removal of solids. A filter in fluid communication with that section is configured to prevent solids from passing through the gas discharge conduit so that the solids can be removed from one of the sections of the solids transfer conduit. A product gas generation system incorporates first and second reactors, the latter of which receives products created by the second reactor.

  • Patent number: 10364398
    Abstract: A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

  • Publication number: 20190217353
    Abstract: A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

  • Patent number: 10286431
    Abstract: A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.
