Abstract: A process is described for preparing ammonium salts of aromatic carboxylic acids by reacting an aromatic carboxylic acid with ammonia in an aprotic solvent, which comprises carrying out the reaction in a closed vessel by continuously introducing a solution of the aromatic carboxylic acid in the aprotic solvent and passing in gaseous ammonia so that an ammonia partial pressure in the range from 0.1 to 3 bar is maintained in the gas space of the vessel, and discharging a suspension of the ammonium salt in the aprotic solvent. The process allows the preparation of ammonium salts of defined crystal size having a narrow size distribution.

Abstract: A gas-turbine supercharging system with improved control. A gas-turbine supercharger that preferably comprises a variable-pitch axial flow fan and a logger supplies, cooled, pressurized air to a gas-turbine power plant. The gas-power plant is preferably a part of combined-cycle power plant that comprises a steam cycle and a duct burner. A controller modulates the output of the fogger and the supercharging fan to maximize the total plant output and provide optimum efficiency without exceeding plant operating limits. The fogger and fan are preferably selected to maximize the allowable output from gas turbine at summer peaking conditions. For the case of a combined-cycle power plant, the preferred mode of operation is to reduce fog output while maintaining a maximum fan pressure as ambient temperature drops below the maximum design value.
