Abstract

In a process and installation for removing solvent vapor from exhaust air sucked from a working space, the air is fed to at least two parallel activated carbon adsorbers. Each adsorber can be switched to and fro between a charging mode in which it adsorbs solvent vapors from the exhaust air flowing through the adsorber, and a regeneration mode in which it is separated from the flow of exhaust air and flushed with water vapor and desorbed. To save energy and to reduce environmental pollution, at the end of the regeneration period each adsorber has a drying phase in which exhaust air from the working space flows through the adsorber, the air thereafter being fed to an adsorber which is operating in the charging mode. In the periods in which an adsorber is operating in the charging mode, it firstly has an initial phase followed by a main phase wherein air flows from adsorbers which are in the main phase are returned directly into the working space while the air flow from an adsorber which is in the initial phase is kept separate from the first-mentioned air flows.
