A method for degassing flowable fluids, in particular liquids used for hydrogen storage, uses a device including a desorber () that can be filled with fluid to be degassed and through which the fluid can flow. A circulation pump () circulates the fluid during a degassing process in the desorber (). A vacuum pump () generates a vacuum in the desorber () during a filling step with fluid and for discharging the gas from the desorber () during the degassing step. At least one sensor () measures the pressure in the desorber () and/or a dwell time. A control unit ends the degassing process when a predefined pressure is measured by the sensor () and/or when a predefined dwell time of the fluid in the desorber () is measured.

Method for degassing flowable fluids

A filter element () is designed as a replacement element and has filter medium () formed as a hollow body and extending between two closure parts in the form of end caps (). The filter medium is pleated with individual filter folds (), and includes a filter material () made of cellulose.
