Process and apparatus for recovering condensable components from fluid streams
Abstract
Abstract THE SPECIFICATION DISCLOSES A PROCESS AND APPARATUS FOR RECOVERING CONDENSABLE, HEAVIER HYDROCARBON COMPONENTS, E.G., PROPANE, BUTANE, ETC., FROM NATURAL GAS STREAMS WHEREIN AT LEAST ONE OF SAID GAS STREAMS ORIGINATES FROM A SOURCE OF GAS RICH IN SAID HYDROCARBON COMPONENTS AND AT LEAST ONE OF THE OTHER GAS STREAMS ORIGINATES FROM A SOURCE OF GAS LEAN IN SAID HYDROCARBON COMPONENTS. THE RICH GAS IS STRIPPED BY OIL ABSORPTION, REFRIGERATION, OR OTHER WELL-KNOWN RICH GAS RECOVERY MEANS. THE LEAN GAS IS STRIPPED BY SOLID ADSORPTION MEANS WHICH UTILIZES AN OPEN-CYCLE REGENERATION SYSTEM WHICH IN TURN IS SUPPLIED WITH A PORTION OF SAID RICH GAS TO ACT AS THE REGENERATIVE GAS. THE REGENERATIVE GAS IS FLOWED THROUGH A SATURATED ADSORBENT BED WHERE IT DESORBS PREVIOUSLY ADSORBED HEAVIER HYDROCARBONS AND CARRIES SAID HYDROCARBONS TO A SEPARATOR WHERE SAID HEAVIER HYDROCARBONS ARE CONDENSED. THE GASEOUS PHASE OF THE REGENERATIVE GAS PLUS DESORBED HEAVIER COMPONENTS ARE RETURNED FROM THE SEPARATOR TO THE RICH GAS STREAM AND ARE STRIPPED THEREWITH IN SAID RICH GAS RECOVERY MEANS.
