Process for improving hydrogen rich gas effluent in refineries comprises adjusting low hydrogen gas effluent to specific pressure, treating gas effluent, reinjecting part of enriched flow into catalytic reforming unit and removing hydrogen
Process for improving hydrogen rich gas effluent in refineries comprises adjusting low hydrogen gas effluent to specific pressure, treating gas effluent, reinjecting part of enriched flow into catalytic reforming unit and removing hydrogen
The low effluent gases (3) are treated in a pressure swing adsorption unit of gases (4), which is supplied by the hydrogen rich effluent gas (1) results from the catalytic reforming unit (2) having two exits, an enriched flow (5) having a hydrogen concentration higher than the hydrogen rich effluent gas and a residual flow (6). The hydrogen from the circuit is removed and reinjected into another unit of the refinery.
