Abstract: An aerosol delivery device having a detachable power source is provided. A control body may be coupleable with a cartridge to form an aerosol delivery device. The cartridge may contain an aerosol precursor composition and be equipped with a heating element configured to activate and vaporize components of the aerosol precursor composition. The control body may comprise a housing and a power source detachably coupled to an outer surface of the housing. A control component may be contained within the housing and configured to operate in an active mode in which the control body is coupled with the cartridge. The control component in the active mode may be configured to direct power from the power source to the heating element to activate and vaporize components of the aerosol precursor composition.

Abstract: A process providing continuous or quasi-continuous sorption uses at least three fixed bed sorbent zones connectable in series by pipes, for the passage of a liquid phase containing a component to be sorbed. The approach of saturation of one or more of the zones is detected, e.g., using temperature sensors, and regeneration of the saturated zone or zones is initiated using hot gas. Compared to conventional sorption processes, energy savings, especially as regards energy consumed in blowing the hot gas through the fixed bed zone, are obtainable.
