PROCESS FOR THE RECOVERY OF HYDROCARBONS FROM A MIXTURE OF HYDROCARBONS AND CARRIER GAS AND, ESPECIALLY, RECOVERY OF METHANE INTO COAL MINES WITH POSSIBLE DECONTAMINATION OF THE AMBIENT AIR

摘要

The invention concerns the recovery of hydrocarbons, but also the enrichment of hydrocarbons thus obtained, with a view to their use as a fuel or as a starting chemical. / P p THE PROCESS CONSISTS OF MAKING THE INVENTORY OF HYDROCARBON RECOVERY. TRANSFERRING AN INTAKE CURRENT CONSISTING OF A MIXTURE OF CARRIER GAS AND HYDROCARBONS IN A FIRST ADSORBER 12 TO GIVE A FIRST EXHAUST CURRENT, HUNTING THIS FIRST EXHAUST CURRENT OF THIS FIRST ADSORBOR 12, TERMINATING THE CIRCULATION OF THE INTAKE CURRENT TO THIS FIRST ADSORBER, SCAN THE ADSORBENT BED OF THIS FIRST ADSORBER 12 BY A SCANNING CURRENT, HUNTING FROM THE FIRST ADSORBENT 12 THE CARRIER GAS CURRENT MOVES AND LOWERING THE PRESSURE OF THE ADSORBENT BED CHARGED WITH HYDROCARBONS OF THIS FIRST ADSORBER , IN ORDER TO DESORBER THESE HYDROCARBONS AND OBTAIN IN THIS WAY, A FIRST PRODUCT CURRENT CONSISTING OF A GAS MIXTURE RICH IN THESE ADSORBED HYDROCARBONS. / P P APPLICATION TO FUELS. / P
