SELECTIVE SEPARATION OF FLUID COMPOUNDS UTILIZING A MEMBRANE SEPARATION PROCESS

摘要

APPARATUS AND PROCESSES ARE DISCLOSED FOR ECONOMICAL SEPARATION OF FLUID MIXTURES UTILIZING PERM-SELECTIVE MEMBRANES. BROADLY, APPARATUS OF THE INVENTION COMPRISES A PLURALITY OF MEMBRANE MODULES COMPRISING A SOLID PERM-SELECTIVE MEMBRANE AND MEANS FOR CONTROLLING ENTHALPY OF SELECTED FLUIDS WITHIN THE APPARATUS. ADVANTAGEOUSLY, THE MEMBRANE MODULES ARE DISPOSED IN A FIRST PRODUCT GROUP, A SECOND PRODUCT GROUP, AND AT LEAST ONE INTERMEDIATE GROUP. APPARATUS OF THE INVENTION IS PARTICULARLY USEFUL FOR SIMULTANEOUS RECOVERY OF A VERY PURE PERMEATE PRODUCT, AND/OR A DESIRED NON-PERMEATE STREAM, FROM FLUID MIXTURES OF TWO OR MORE COMPOUNDS WHICH WHEN SUBJECTED TO APPROPRIATELY ALTERED CONDITIONS OF TEMPERATURE AND/OR PRESSURE EXHIBIT A BUBBLE POINT.FIG. 1
