Patent CA-2557560-A1 (CA)
Inventor: JUDGE JOHN FRANCIS
IPC: F04C28/08
Filed: 2005-02-25
Abstract: A system and method are provided for variable speed operation of a screw compressor (108) to obtain increased capacity and efficiency. The screw compressor (108) is connected to an induction motor (106) driven by a variable speed drive (104), wherein the screw compressor (108) has a variable output capacity that is dependent on the output speed of the motor (106). To obtain increased capacity and efficiency, the screw compressor (108) is operated at a speed greater than the screw compressor's rated speed and does not include a slide valve. The maximum operating speed of the screw compressor (108), which speed is greater than the rated speed, is related to the maximum operating speed of the motor (106) when operated at a voltage and frequency provided by the variable speed drive (104) that is greater than the motor's rated voltage and frequency in a constant flux or constant volts/Hz mode.

Title: Method for optimizing operational parameters on wind farms
Inventor: ALTEMARK JENS
IPC: F03D7/02
Filed: 2005-11-22
Abstract: The invention relates to a method for optimising operational parameters of a wind farm, in particular in relation to the rotor/generator system thereof, by determining an upper and a lower interval threshold value (110) for a parameter which is to be optimised. The method according to the invention is characterised by a cycle of the wind farm having alternating operations (112, 114, 118, 120), provided with interval threshold values. A data set is generated (116, 122) having a target variable, and repeated (126) according to an adjustable number of times. The data set is evaluated in relation to the interval threshold values and a quality level is formed. The interval threshold value is identified by means of the low quality level (130). At least said interval threshold value is modified by displacing about a step value .DELTA. in the direction of the other interval threshold value (134, 136). Said cycle is repeated (137). Said inventive method is simple to carry out and enables optimum parameters to be automatically detected even under difficult conditions, for example, stochastically acting disturbances (wind fluctuations). The invention also relates to a wind farm for carrying out said method.

Abstract: A low cell density fermentation process for the production of heterologous proteins in microorganisms. The cell culture obtained by cultivating host microorganisms transformed with a vector carrying genetic material for the said proteins and an inducible promoter under batch fermentation conditions is fed with a feed medium after an OD600 of 0.16 to 8 has been achieved or after 0 to 4 hrs from the start of the fermentation process. The feed medium comprises 5 to 30% of carbon source and 1 to 30% of nitrogen source and 0 mg to 400 mg antibiotics and 2.5 to 4.25% inorganic phosphates and trace elements. The concentration of the carbon source in the feed medium is 10 to 30 and the amino acid content in nitrogen source is 45 to 95%. The initial feed rate is in the range of 0 ml/hr to 12 ml/hr and is raised exponentially by an exponent in the range of 0.1 to 0.4 and/or linearly with the slope of the curve in the range of 0.5 to 3. The production of the heterologous proteins is induced with 0.01 - 4% inducer at a cell density of OD600 0.1 -OD600 50. The feeding of the cell culture with the feed medium and the feed rate described above is continued after production has been induced. The pO2 is adjusted between 10% to 60% by passing sterile air into the fermentation broth and the temperature and pH of the fermentation broth are maintained at 33~C - 41~C and 6.9 - 8.5, respectively during the entire fermentation.

Title: In situ heavy oil and bitumen recovery process
Inventor: ADAMS JENNIFER JANE
IPC: E21B43/16
Filed: 2007-07-13
Abstract: The present invention is directed to an in situ reservoir recovery process that uses a horizontal well located near the top of a reservoir and an inclined production well to extract bitumen or heavy oil from a reservoir. The process may consist of a first stage in which the top well is used for cold production of reservoir fluids to the surface. In cold production, reservoir fluids are pumped to the surface in the absence of stimulation by steam or other thermal and/or solvent injection. In the present invention, a lower production well is drilled into the formation below the top well. The top well is converted to an injection well or, if no cold production then a top well is drilled as an injector well. A portion of the bottom well is inclined so that one end of the incline is closer to the injector well than the other end of the incline. Alternatively, the new bottom well is inclined at an angle so that the interwell distance between the toes of both wells is less than the interwell distance between the heels of both wells. In the process, steam circulation creates a heated zone at the point of the two wells that are closest together in the reservoir. For example, for an inclined bottom well, this is at the toes of the wells. After thermal communication between the two wells is established, then the wells are switched to a SAGD-like mode: steam or other injectants are injected into the top well and reservoir fluids are produced from the bottom well. The process preferentially produces the relatively lower viscosity oil from the upper portions of the reservoir in the early stages of the process. Later, as the steam chamber expands downwards into the reservoir along the wells, the produced oil contains higher amounts of the heavier, higher viscosity oil found nearer the bottom of the reservoir. The process is particularly useful in the recovery of heavy oil or bitumen from a reservoir that exhibits vertical and lateral areal oil phase viscosity variations. The method is also very useful in reservoirs with bottom water.
