Abstract:
A support rib for securing a rotor pole to a flange in a gearless drive is described. The support rib is undivided and passes through an opening of the flange. The support rib can be joined with the flange and/or the rotor pole using an adhesive. The rib preferably has at least one notch that engages an edge of the flange opening to establish mechanical connection between the rib and flange. An insert with two ends that slideably engages a rib edge and rotor pole channel can be used to couple the rib to the rotor pole.
Abstract:
A process for dewatering crude oil is described. The process includes feeding crude oil onto a separation of a cyclone separator that is at least partially disposed in a flash vessel. The temperature are pressure in the flash vessel are selected such that at least 20% of the water contained in the crude oil is flashed from the crude oil as it moves on the separation surface of the cyclone separator. The flow rate and angle of the crude oil inlet is selected such that the crude oil moves across the separation surface as a film in a helical pattern, providing a substantial foaming-free manner. The vapor that is flashed from the crude oil exits the flash vessel at a top outlet and the liquid crude oil exits the flash vessel at a bottom outlet.
Abstract:
A system of monitoring a black cell environment using sensors is presented, in which the sensors can be easily replaced during a sealed period of the black cell environment. The black-cell monitoring system includes at least one sealed vessel that is disposed within the black cell environment. The vessel is configured to store a hazardous mixed substance and is sealed from the external environment for a pre-determined amount of time. The black-cell monitoring system also includes at least one tubing that extends from the outside of the vessel to the inside of the vessel. The black-cell monitoring system also includes a fiber optic cable that is disposed within the lumen of the tubing. At least a portion of the fiber optic cable is disposed within a portion of the tubing located inside the sealed vessel.
Abstract:
A method and a system of integrating anew robot into a work environment are provided. A controller receives a signal indicating a presence of a new robot in the work environment. The controller then establishes a negotiation channel between the controller and the new robot and begins to negotiate with the new robot a set of robotic functions controllable by the controller. Based on a comparison between a set of function attributes the new robot and interface attributes of the controller, the controller generates a new robot user interface for controlling the set of robotic functions of the new robot.
Abstract:
Electronic comparison methods are described for determining changes in a current design model with respect to an earlier model and analyzing the impact of the identified changes. The method includes associating a priority value with a set of modified component objects using one or more algorithms and presenting a subset of the set of component objects, each of which has a priority value greater than a threshold value.
Abstract:
Systems and methods for pipeline network optimization are presented. The pipeline network can be represented through a flow model, which can include a plurality of modeled wells operatively coupled to production facilities through one or more flowlines. Risk profiles of the one or more flowlines can be determined based on flowline attributes of each flowline and based on a simulation of the flow model that uses production variation in wells connected to the respective flowline as a parameter to generate flow profile of the flowline. Understanding the risk profile of each flowline through a risk metric can help assess the production potential of each flowline and wells associated thereto and optimize the network cost of operation or maintenance.
Abstract:
Systems and methods are described for actuating a plurality of pneumatic valves to positively isolate one or more pieces of equipment. A manual valve can be disposed on a supply conduit that fluidly couples each of the pneumatic valves to a fluid supply source. To place the pneumatic valves in a safe position, the manual valve can be closed, which disrupts a flow of fluid from the source. Closing the manual valve can also open a drain conduit that allows the supply conduit to be depressurized.
Abstract:
Sulfur emissions from liquid sulfur are reduced, or even entirely avoided by degassing the liquid sulfur at pressure in an out-of-pit vessel and by sweeping the rundown pit (or vessel) with a sweep gas that is non-poisonous for a hydrogenation catalyst. Acid gases from degassing are fed at pressure to the Claus unit, while sweep gases are fed to the tail gas treatment unit to substantially recycle the acid gases to extinction. In preferred plants and methods, motive fluids and booster eductors or compressors are not needed, and incineration of the acid gases can be avoided.
Abstract:
A low cost and efficient design is used to convert a propane recovery process based on low nitrogen content feed gas to an ethane recovery process based on a high nitrogen feed gas while achieving over 95 mole % ethane recovery while maintaining a 99% propane recovery, and achieved without additional equipment.
Abstract:
A natural gas two-column processing plant allows for recovery of at least 95% of C4 and heavier hydrocarbons, and about 60 to 80% of C3 hydrocarbons from a rich feed gas stream in which the first column (absorber) operates at a higher pressure than the second column, with the absorber receiving a compressed gas from the second column, and a turboexpander discharging a two-phase stream to the top of the absorber. Most typically, contemplated configurations and methods operate without the use of external refrigeration.
