Hydrocarbon gas is separated from a gas mixture by concentration swing adsorption in a system consisting of a pair of adjacent adsorption beds that are contained in a cylindrical vessel and separated by a flat partition wall. The system is operated with the beds out of phase, such that one bed is in adsorption service while the other bed is regenerated by purging the bed with air. The pressure and temperature in the bed undergoing adsorption does not differ from the pressure and temperature, respectively in the bed being regenerated sufficiently to create significant stresses in the partition separating the beds. In a modified version, the gas mixture and purge air are dried by simultaneously passing these gases through one pair of adjacent adsorption beds that are contained in a cylindrical vessel and separated by a flat partition wall with the respective pressures and temperatures in the two beds being substantially equal, while a substantially identical pair of adjacent adsorption beds are being regenerated by passing heated nonadsorbed gas from the hydrocarbon adsorption system through the beds at a substantially constant temperature and pressure.
