Abstract: Dehumidifier for photovoltaic modules, of a series of photovoltaic concentration modules, formed by a common air inlet and outlet access that communicates all the modules, and which passes through a bed of moisture absorbing material, having an electrical self-adjusted resistance (15) installed therein. The circuit is completed with a solenoid valve (13), a flow switch (19), a non-return valve (12); a pressure switch (16) and a timer relay (20). The process is based on pressure differences existing within the photovoltaic modules throughout the day, and consists of two steps: drying air by passing through the bed of absorbent material before entering into the photovoltaic modules and the regeneration of the drying system, which can be automatically or manually by connecting a compressor or fan.

Abstract: In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification.

Abstract: Fluorinated metal-organic frameworks (“FMOFs”) are capable of adsorbing and desorbing hydrocarbons, namely, C6-C8 hydrocarbon oil components (n-hexane, cyclohexane, benzene and toluene). FMOFs can be arranged in a variety of configurations and have internal hollow channels and cavities. In FMOFs, hydrogen atoms have been substituted completely or partially with fluorine atoms or fluorinated groups in each linking organic ligand. These FMOFs can adsorb C6-C8 hydrocarbons, up to 500 kg/m3 as demonstrated for toluene, through a combination of superhydrophobicity and capillary action. No water adsorption was detectable even under extreme conditions including moist air near 100% relative humidity and immersion in water for multiple weeks, demonstrating far superior water resistance to BPL carbon and zeolites. These materials are stable and can be readily recycled by simple desorption many times.

Abstract: The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (CO2), particularly from the air. The CO2 extraction methods and systems involve the use of chemical processes. Methods are also described for extracting and/or capturing CO2 via exposing air containing carbon dioxide to a solution comprising a base—resulting in a basic solution which absorbs carbon dioxide and produces a carbonate solution. The solution is causticized and the temperature is increased to release carbon dioxide, followed by hydration of solid components to regenerate the base.
