摘要： Systems and processes disclosed herein relate to the utilization of direct contact condensing to provide heat to a solvent regeneration loop in an acid gas removal process. A first direct contact condenser can be included in the upper section of a concentrator that removes acid gas from a rich solvent stream. A first slip stream can be heated in the first direct contact condenser and can be combined with the rich solvent stream in the lower section of the stripper. A second direct contact condenser can be included in the lower section of an absorber that removes acid gas from a feed gas. A second slip stream can be heated in the second direct contact condenser, and can be combined with the rich solvent stream before the rich solvent stream is provided to the concentrator.

摘要： Systems and processes utilize one or more methods of providing overhead waste process heat to increase the feed temperature of the hot solvent stripping regeneration loop in an acid gas removal process. A heated rich solvent stream can be the primary feed for the hot solvent stripping regeneration loop, and one or more slip streams can be heated and then combined with the heated rich solvent stream to form a combined rich solvent stream prior to further processing in downstream units to remove acid gas from the solvent. A first slip stream can be heated in a stripper gas heat exchanger by heat exchange with a stripped gas stream. A second slip stream can be heated in a regenerator exchanger by heat exchange with an acid gas stream. A third slip stream can be heated in a recycle gas exchanger by heat exchange with a compressed recycle gas stream.

摘要： A simulation system includes at least one processor configured to execute a computer program product, stored upon a storage medium. The computer program product includes a spreadsheet application, a process simulation application, and an integration tool (e.g., eSim), where the spreadsheet application and the process simulation application are discrete, stand alone products. The process simulation application can simulate chemical processes using at least one flowsheet, which models a general flow of chemical plant processes and equipment. The integration tool can map process simulation application objects and properties to spreadsheet application objects, can convey information between mapped objects, can perform case management functions, and can perform orchestrated calculation functions.

摘要： A duplex optical transmission-reception module includes an optical fiber. A light-receiving element which corresponds to the optical fiber for receiving optical energy transmitted through the optical fiber from a distal end and converting the optical energy into electric energy which is output from an output terminal. A light-emitting element connected on the light-receiving element. The light-emitting element is projectively aligned with the end face of the optical fiber. When the light-emitting element is energized to project light beam outward, the light beam is projected right to the end face of the optical fiber and input to the optical fiber. The light beam is transmitted along the optical fiber to the distal end to be received by another receiver to output a signal. The function of duplex transmission can be achieved without mounting any refractive element between the optical fiber, the light-receiving element and the light-emitting element.

摘要： A semiconductor device and a method of fabricating thereof, including an insulator layer having alternately layered insulator films and boundary layers, wherein the boundary layers are more dense than the insulator films to prevent expansion and elongation of string-like defects across the boundary layers. The method includes mixing a nitrogen containing gas and a silane group gas to form an insulator film; temporarily stopping a flow of the silane group gas for approximately one to fifteen seconds to form a boundary layer over the insulator film; restarting the flow of the silane group gas; and repeating the steps of temporarily stopping and restarting for a predetermined number of times to form the plurality of alternately layered insulator films and boundary layers. The plurality of alternately layered insulator films and boundary layers is also etched at an etching rate for the insulator films greater than an etching rate for the boundary layers to form a step-shaped sloped opening.
