Title (EN) HYBRID GAS PURIFICATION
(FR) PURIFICATION DE GAZ HYBRIDE
Abstract:
(EN) A gas purification system (100) is described. The gas purification system (100) includes a Rotating Packed Bed (RPB) unit (102) and a Pressure Swing Adsorption (PSA) unit (104). The RPB unit (102) includes a gas inlet (106) to receive the mixed gas feed including multiple impurities, a solvent to eliminate a first set of impurities to obtain an enriched gas, and a gas outlet (108) to supply the enriched gas. The PSA unit (104) includes an inlet (124) coupled to the gas outlet (108) of the RPB unit (102) to receive the enriched gas, multiple adsorption beds (126) to eliminate a second set of impurities from the enriched gas, and a product gas outlet (128), to provide a product gas.
(FR) L'invention concerne un système de purification de gaz (100). Le système de purification de gaz (100) comprend une unité de lit fixe rotatif (RPB) et une unité d'adsorption modulée en pression (PSA). L'unité RPB (102) comprend une entrée de gaz (106) pour recevoir la charge de gaz mixte comprenant de multiples impuretés, un solvant pour éliminer un premier ensemble d'impuretés afin d'obtenir un gaz enrichi, et une sortie de gaz (108) pour fournir le gaz enrichi. L'unité PSA (104) comprend une entrée (124) couplée à la sortie de gaz (108) de l'unité RPB pour recevoir le gaz enrichi, de multiples lits d'adsorption (126) pour éliminer un second ensemble d'impuretés du gaz enrichi, et une sortie de gaz de produit (128), pour fournir un gaz de produit.
