METHOD AND PLANT FOR ENRICHING A COMBUSTIBLE GAS MIXTURE IN AT LEAST ONE COMPONENT THEREOF

摘要

Part of the flux of a combustible gas mixture, flowing in a distribution line (1), is taken off (13), compressed (12) and treated as a recycle gas (10) in a unit (3) for production of an active gas (4) from a synthetic gas mixture (6). Said part of the flux in which the fraction of the active component has been effectively eliminated is reinjected (at 15) into the line (1). The above particularly finds application in petrochemical sites.
