Abstract

The invention relates to a method for dehumidifying a gas including water vapour, said method including: a step of sucking the gas to be dehumidified into the driers (17); a step of cooling the gas in the driers (17), by means of the cooling system, down to a solidification temperature of the water contained in the gas to be dehumidified; a step of compressing the gas thus dehumidified; and a de-icing step during which the ice in the driers (17) is liquefied when the amount of ice accumulated in the driers (17) reaches a predetermined threshold.

Abstract

A method for cooling a product by means of a cooling machine (1) comprising: - a source (4) supplying a refrigerant; - a vent (32) for discharging the refrigerant; - a cooling chamber for receiving the product to be cooled; machine (1) within which the product is contained in a container (2), said container (2) being disposed within the cooling chamber, in which said method comprises an operation: - of cooling the cooling chamber by means of the refrigerant; - discharging the refrigerant fluid by means of the vent (32); the container (2) being in direct contact with the refrigerant.

Abstract

Device (1) for extraction of a chemical compound from a gas, of which the initial composition, the flow rate and the partial pressure of the chemical elements are known, this device comprises an inlet (7) through which the polluted gas rushes in and an outlet (8) through which the decontaminated gas escapes, the device (1) comprises at least one pollution-control stage (2) defining a flow area of the gas, this pollution-control stage (2) comprising means (9) for injecting an acid solution into the gas.

Abstract

The invention relates to a method for dehumidifying a psychometric gas mixture at room temperature, including one step, said step including: a compression phase, in which the psychometric gas mixture is compressed to a given pressure; a cooling phase, in which the previously compressed psychometric gas is cooled to a given temperature; a separation phase, including a step of extraction of the condensates from the previous cooling step, in the psychometric gas; the previously described step being repeated consecutively and a plurality of times, such as to reduce the water vapor concentration in the psychometric gas to a predetermined threshold.
