  • Publication number: 20100324158
    Abstract: A reactor module for Fischer-Tropsch synthesis having a generally rectangular reactor block with a stack of plates defining flow channels for coolant and flow channels for the synthesis reaction arranged alternately in the block. The synthesis flow channels extend in a generally vertical direction between upper and lower faces of the reactor block and are defined by plates in combination with either bars or sheets such that each channel is of width no more than 200 mm. The coolant flow channels are oriented in the same direction, and communicate through distributor chambers with inlet and outlet ports at side faces of the reactor block. A plant may contain a multiplicity of such reactor modules operating in parallel, the modules being interchangeable and replaceable. The temperature control is enhanced by allowing the coolant flow to be parallel to the synthesis gas flow.

  • Patent number: 7842256
    Abstract: A compact catalytic reactor for Fischer-Tropsch synthesis defines a multiplicity of first and second flow channels arranged alternately in the reactor, for carrying a gas mixture which undergoes Fischer-Tropsch synthesis, and a coolant fluid, respectively. Each first flow channel contains a removable gas-permeable catalyst structure incorporating a metal substrate. A multiplicity of flow paths are defined through the catalyst structure, and the voidage, that is to say the proportion of the cross-sectional area of the first flow channel constituted by the said multiplicity of flow paths, is between 25% and 70%. This provides an optimum balance between productivity and selectivity, so that operation of the reactor can be economic and controllable.

  • Publication number: 20100269866
    Abstract: A wash fluid distribution system for dishwashers includes a spray arm mounted in one of four quadrants of a chamber floor. The spray arms can have lengths that maintain full rotation within their respective quadrant. Spray arms can also have lengths that impinge or overlap into an adjacent quadrant during full rotation of the spray arms. Each spray arm operates with a corresponding, independently controlled wash pump system. Adjacent spray arms can rotate at a same speed in opposing clockwise or counter-clockwise directions. Spray arms can also rotate in different rotation planes. A slanted surface on the chamber floor terminates at a shared particle collection area, which is centered on the chamber floor.

  • Publication number: 20100209084
    Abstract: A heat pump water heater and systems and methods for its control are disclosed. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.

  • Publication number: 20100083007
    Abstract: A method, system, and computer usable program product for improving processor performance during power supply failure are provided in the illustrative embodiments. A throttled condition of a processor is detected in a data processing system. A voltage of the electrical power being provided to the processor is reduced. The processor is un-throttled. Additionally, a frequency of electrical power being provided to the processor may also be reduced. A determination is made whether a condition that caused the throttling has been corrected. In response to the condition having been corrected, the frequency is returned to normal frequency and the voltage is returned to normal voltage. The reducing the frequency operation and reducing the voltage operation may each be performed by distinct components communicating over a data network external to the data processing system.
