摘要： A scale suppression apparatus capable of suppressing in a low-priced manner the generation of silica-based scale and calcium-based scale in the influent water containing at least a silica component and a calcium component, a geothermal power generation system using the same, and a scale suppression method are provided. The scale suppression apparatus includes a chelating agent and alkaline agent addition unit injecting liquid containing a chelating agent and an alkaline agent into a pipe arrangement through which influent water such as geothermal water or the like flows, and a controller controlling a pump and a valve of the chelating agent and alkaline agent addition unit. The controller controls the injection of the chelating agent and the alkaline agent and stops of the injection based on the signal output from a scale detection unit for detecting a precipitation state of the scale.

摘要： A scale suppression apparatus capable of suppressing in a low-priced manner the generation of silica-based scale and calcium-based scale in the influent water, a geothermal power generation system using the same, and a scale suppression method are provided. The apparatus includes a first addition unit configured to add liquid containing a chelating agent and an alkaline agent to influent water flowing through a pipe arrangement to make the influent water higher than pH 7, a second addition unit configured to add an acid substance to the influent water to make the influent water lower than pH 7, and a controller configured to alternatively switch between the operation of the first addition unit and the operation of the second addition unit. The controller controls the switching of the first addition unit and the second addition unit based on the signals output from a scale detection unit and a pH meter.

摘要： A device for automatically detecting and removing air from a gas mixture of an organic gas and air includes calculating a saturation pressure value based on a temperature of the gas mixture in a reservoir 1, and obtaining a pressure threshold value by adding a margin value to the saturation pressure value. When the pressure value inside the reservoir 1 is higher than the pressure threshold value, air is detected to be in the gas mixture. After this detection, a controller 5 pressurizes and introduces the gas mixture into a pressure container 2 to condense the organic gas in the gas mixture, thus producing a diluted gas mixture. Subsequently, the diluted gas mixture is introduced to a supply side of a membrane unit 3, the organic gas in the diluted gas mixture is recovered at a permeation side thereof, and a residual gas is discharged outside of the device.
