Abstract:
A mobile device for monitoring and controlling systems while moving about within a facility is described. The mobile device includes a processor, memory, a display, and software for viewing and managing system data. The device provides produces augmented views of the facility by overlaying actual facility video camera images with other sensor derived data, identification data, and control recommendations. The device generates the control recommendations based, in part, on the device's location and orientation, and on system operation rules and parameters.
Abstract:
A system and method for creating a project workflow involves tracking all activities from all disciplines within a company in a database, such that when a new workflow is created, a project architect is forced to consider every activity ever performed to the workflow in relation to every discipline. Only after activities have been assigned to their appropriate disciplines, can a user filter a view of the map to hide disciplines and activities from view. This ensures that every task ever performed by various disciplines within a company is always considered whenever designing a project workflow.
Abstract:
A headgear assembly for a baghouse filter can include a headgear configured to allow for concentric arrangement of first and second filters coupled thereto, where at least one of the first filter, second filter, and headgear can include an opening through which accumulated particulate from the second filter can pass. The headgear assembly can also include a cleaning assembly configured to facilitate cleaning of at least one of the first and second filters. Methods of facilitating on-line cleaning of a baghouse filter are also described wherein an exhaust stream is passed through concentrically arranged first and second filters to produce a filtered stream. At least one of the first and second filters can be cleaned using a cleaning assembly to remove accumulated particulate, which can pass through an opening in at least one of the first filter, the second filter, and the headgear.
Abstract:
Produced water is treated by raising the pH to a level that significantly increases silica solubility and breaks emulsions. So treated water is then de-oiled, filtered, and subjected to ion exchange chromatography to reduce water hardness prior to feeding into a steam generator to form an intermediate quality steam. If desired, the intermediate quality steam is directly used in SAGD, or separated into a high quality steam and condensate, which is further treated to obtain additional water that can then be used in the steam generator.
Abstract:
A sulfuric acid production plant has a discontinuously operating back-up absorber to allow for sulfur emission control in situations where part of or even the entire sulfuric acid production plant is shut down, inoperable, or otherwise compromised. The back-up absorber receives lean solvent from a storage tank that is configured such that continuous operation of the back-up absorber is possible for several hours.
Abstract:
Disclosed is a reactor, a retained catalyst structure, and a method for increasing the rate of decomposition of polysulfides and removal of hydrogen sulfide in liquid sulfur. The reactor, the retained catalyst structure, and the method include a retained catalyst structure arranged and disposed for contacting a first stream and a second stream in a reactor including a catalyst. The catalyst increases the rate of decomposition of polysulfides and facilitates the removal of hydrogen sulfide in the liquid sulfur of the first stream with the second stream. The first stream includes liquid sulfur containing polysulfides and dissolved hydrogen sulfide. The second stream includes an inert gas or a low oxygen-containing gas.
Abstract:
A syngas treatment plant has a decarbonization section and a desulfurization section that use the same solvent to remove various acid gases. Contemplated methods and plants are highly effective in removal of CO2, recycle sulfurous contaminants to extinction. Minimal loss of H2 while maximizing H2S concentration in a Claus plant feed during regeneration of the solvent is achieved by stripping the solvent with both treated syngas and a flash vapor of the desulfurization section.
Abstract:
An ultrasound time-of-flight diffraction reference block has a plurality of notches that extend into the block to simulate cracks, wherein the notches have a normal and transverse orientation with respect to a test path formed on the block.
Abstract:
A skim tank includes a flow-control structure that forces a solid-depleted phase of a mixed-phase feed into a toroidal motion within the container to thereby provide an up-flow movement within the structure. Most preferably, at least a portion of the solid-depleted phase is recirculated to further increase up-flow movement within the structure.
Abstract:
High-pressure feed gas is chilled and expanded to condense a portion of the feed gas into a C2+ enriched liquid phase and a C2+ depleted vapor phase. The liquid phase is expanded to provide additional cooling for the feed gas and deethanizer reflux prior to being fed to the deethanizer while the vapor is combined with residue gas of a deethanizer.
