    摘要: The present invention pertains to a method and an installation or system for drying fibrous material. The method comprises the step of ventilating very moist air through the fibrous material located in a drying zone. The moisture content of the moist air is less than that inside the drying zone, its pressure is close to atmospheric pressure and its temperature is higher than that of the material to be dried. The method additionally comprises the step of recovering the heat of condensation of the water vapor extracted from the fibrous material to heat the moist air, providing leaks between the outside ambient air and the ventilation circuit upstream and downstream of the drying zone, making possible a mass and heat exchange. It is possible to ensure heat and mass balance without expelling large amounts of moist air into the ambient air.

    摘要: The present invention relates to a method and a system for controlling the circulation of water films on the exchange walls of an exchange surface of a cooling tower. It comprises combining a tank and a dispenser lip to ensure that the film has a specific thickness and that it adheres to the exchange wall right from the moment it starts to flow and repeatedly so, on each exchange wall. The exchange walls between air and water are horizontally sloping at a small angle, thereby ensuring that the water flows by force of gravity and, at the same time, limiting the speed increase on the plate to avoid the droplets from being pulled away by the airflow. The water films are recovered in recovery troughs perpendicular to the flow of the water films on the plates. These troughs are tilted horizontally, and enable the recovery of the water films without being crossed by the air flows. The air is blown in by nozzles which are interposed between the water flow plates in such a way that the airflow is in a counter-current flow or, if necessary, in a cross-current flow, relative to the water films thus enabling the evaporation of the water that cools the water flow on the exchange plates without forming liquid aerosols.

    摘要: The invention provides a method and a system for extracting a substance comprised in a gaseous mixture, the extraction being carried out in a cyclic manner in 2N chambers (AA, BB, CC, DD), each provided with a heat-exchanger (A, B, C, D), N being an integer greater than or equal to 3. Each chamber carries out a cycle comprising the following four steps in succession: a frosting step, a defrosting step, a step of recovering the liquid phase and the residual gas phase, and a temperature-reduction step of reducing the temperature of the heat-exchanger. Further, sequencing the passage from one step to another in each of the chambers is such that the number of chambers carrying out the frosting step and also the total number of chambers carrying out the defrosting, recovery, and temperature-reduction steps are both equal to N.
