Description
technical field [0001] The invention relates to a process gas dehumidification system and method according to the preambles of claims 1 and 15 . Background technique [0002] In many different industry sectors, such as agriculture, automotive, chemical processing, etc., it is very important to maintain the relative humidity of atmospheric or process gases (such as gases enclosed in or flowing into spaces such as storage rooms, production facilities, data centers, etc.), Within the limits specified to prevent undesired effects such as corrosion, electrical failure, bacterial growth, etc. [0003] One way to accomplish this is to remove process gas from the space and reintroduce it and / or introduce new process gas into the space through a dehumidifier that removes excess moisture from the process gas. [0004] A dehumidifier can absorb moisture from the process gas, for example using a hygroscopic agent in the dehumidifier. In order for the process gas to be continuously deh...
