  • Patent number: 6434435
    Abstract: The systems and the methods relating to process control optimizations systems useful to manage oilfield hydrocarbon production. The systems and the methods utilize intelligent software objects which exhibit automatic adaptive optimization behavior. The systems and the methods can be used to automatically manage hydrocarbon production in accordance with one or more production management goals using one or more adaptable software models of the production processes.

  • Patent number: 6112126
    Abstract: The present invention relates to process control optimization systems which utilize an adaptive optimization software system comprising goal seeking intelligent software objects; the goal seeking intelligent software objects further comprise internal software objects which include expert system objects, adaptive models objects, optimizer objects, predictor objects, sensor objects, and communication translation objects. The goal seeking intelligent software objects can be arranged in a hierarchical relationship whereby the goal seeking behavior of each intelligent software object can be modified by goal seeking intelligent software objects higher in the hierarchical structure. The goal seeking intelligent software objects can also be arranged in a relationship which representationally corresponds to the controlled process' flow of materials or data.

  • Patent number: 6095336
    Abstract: A froth flotation cell comprising a tank and an impeller rotatably disposed in the tank for suspending solids and dispersing air in a pulp phase or slurry in the tank, thereby generating froth from the pulp phase. A plurality of radially oriented launders are placed near the top of the tank and have one end connected to an outer launder adjacent the outer periphery of the tank. A secondary launder, concentric with the outer launder may also be placed near the top of the tank and attached to the second ends of the radial launders. The secondary launder is attached to a dispersing mechanism located around the impeller. The secondary launder is in fluid communication with the radial launders, and the radial launders are likewise in fluid communication with the central launder. This provides a network of launders which collects froth at various locations throughout the flotation cell and causes rapid removal of froth from the flotation cell.

  • Patent number: 4752383
    Abstract: An apparatus and method for generating gaseous bubbles in a liquid body comprises a bubble chamber for mixing a pressurized gas with a liquid at a pressure greater than atmospheric and a fine injector tip for releasing the pressurized gas-liquid mixture from the bubble chamber under a high tip velocity and shear. The apparatus is adapted for supplying bubbles to a flotation column for the treatment of mineral ore materials.
