  • Patent number: 8073654
    Abstract: Process for controlling the energy performance of an industrial unit, in which process: the value of a set (V) of variables relating to the industrial unit and to the environment are measured, as is the value of a quantity representing the energy performance (W), an estimate (We) of the quantity representing the energy performance is calculated, the value of an energy performance indicator (TE, TE+) is determined and the value of this indicator is compared with at least one threshold value (S) determined so as to detect a drift in the energy performance. The invention proposes the learning of a model based on the best energy performance (W) observed for each value of a set (V) of input variables and in the proposing in real time to the operator of a best configuration and of best settings (CR) of the equipment based on those associated with this best energy performance (W) observed in the past for the current value of the set (V) of input variables.

  • Patent number: 8065879
    Abstract: A process for the integration of a cryogenic air separation plant and an oxy-combustion power plant is presented. This process includes producing a pressurized nitrogen stream and a pressurized oxygen stream, burning a fuel stream thereby generating a steam stream from a boiler feed water stream, wherein the stream is used for work expansion within the oxy-combustion power plant. This process also includes heating the pressurized nitrogen stream and the pressurized oxygen stream with a compressed air stream, thereby forming a heated pressurized nitrogen stream and a heated pressurized oxygen stream. This process also includes heating the heated pressurized nitrogen stream to form a hot pressurized nitrogen stream, work expanding the hot pressurized nitrogen stream to a lower pressure thereby forming a hot exhaust nitrogen stream and recovering energy, and heating the boiler feed water stream by indirect heat exchange with the hot exhaust nitrogen stream.

  • Patent number: 8061682
    Abstract: A valve for controlling the flow of a pressurized fluid, in particular a medical or industrial gas, a fluid inlet, a fluid outlet, and a internal fluid passage that connects them. A valve for controlling the fluid flow can prevent the circulation of a fluid in this passage, and an actuator utilizing a pivoting lever can be manually actuated by an operator. This lever pivots around a pivot point and can move between at least three stable, angularly staggered positions including a rest position where there is zero fluid flow in the internal fluid passage a intermediary released position where the fluid flow remains zero and an active position with fluid flowing thorough the internal fluid passage at a non-zero rate.

  • Patent number: 8056580
    Abstract: A valve to control the flow of pressurized fluids, such as medical or industrial gases, consists of a body with an internal fluid distribution circuit, comprising a fluid inlet, a fluid outlet, and a internal fluid passage connecting them. Fluid flow can be controlled by an operator manually actuating a lever. This lever can move between at least three stable positions that are angularly staggered in relation to each other. In the rest position, the lever is fixed and solidly connected to the body of the valve, and there is zero fluid flow in the internal fluid passage. In the intermediary released position, the lever is disconnected from the body, but the fluid flow remains zero. In the active position, the lever is disconnected from the body, and fluid flows thorough the internal fluid passage at a non-zero rate. Application also to gas cylinders equipped with such valves.
