Continuous process for adsorbtion-desorption

Claim 1

A PROCESS FOR CONTINUOUSLY SEPARATING ORGANIC COMPOUNDS CAPABLE OF BEING SELECTIVELY ADSORBED BY CONTACT IN THE LIQUID PHASE WITH A SOLID ADSORBENT WHICH COMPRISES CONTINUOUSLY MOVING PARTICLES OF A SUITABLE SOLID ADSORBENT AGGLOMERATED INTO A COLUMNAR MASS OR BED DOWNWARDLY IN A SINGLE VERTICAL ELONGATED COLUMN, CONTINUOUSLY FEEDING SAID ORGANIC COMPOUNDS IN THE LIQUID PHASE INTO CONTACT WITH THE MOVING MASS OF ADSORBENT AT A POINT BELOW THE TOP OF SAID COLUMN, CONTINUOUSLY WITHDRAWING A LIQUID NON-ADSORBED FRACTION FROM THE TOP OF SAID COLUMN AS A RAFFINATE PRODUCT, CONTINUOUSLY INTRODUCING INTO SAID COLUMN AT A POINT BELOW THE POINT OF FEEDING SAID ORGANIC COMPOUNDS A REFLUX STREAM COMPRISING A PORTION OF THE MORE READILY ADSORBED COMPONENTS OF SAID ORGANIC COMPOUNDS RECOVERED AS EXTRACT PRODUCT AS DESCRIBED HEREINBELOW AND FLOWING SAME UPWARDLY THROUGH SAID COLUMN TO EFFECT RECTIFICATION THEREIN, CONTINUOUSLY MAINTAINING IN SAID COLUMN A STATIONARY ZONE OF LIQUID BELOW THE POINT OF INTRODUCTION OF SAID REFLUX STREAM, CONTINUOUSLY INTRODUCING INTO THE BOTTOM OF SAID COLUMN A LIQUID DESORBENT LESS READILY ADSORBED THAN SAID EXTRACT PRODUCT PORTION OF SAID ORGANIC COMPOUNDS AND FLOWING SAME UPWARDLY THROUGH SAID COLUMN UNDER CONDITIONS EFFECTING DESORPTION OF THE ADSORBED PORTION OF SAID ORGANIC COMPOUNDS, CONTINUOUSLY WITHDRAWING FROM SAID COLUMN AT A POINT ABOVE THE BOTTOM THEREOF BUT BELOW SAID STATIONARY LIQUID ZONE A LIQUID STREAM COMPOSED OF SAID LESS READILY ADSORBED DESORBENT LIQUID AND DESORBED ORGANIC COMPOUNDS, SEPARATING SAID LAST NAMED WITHDRAWN STREAM INTO LIQUID DESORBENT AND DESORBED ORGANIC COMPOUNDS AND RETURNING THE FORMER TO THE BOTTOM OF SAID COLUMN, AND DIVIDING THE THUSRECOVERED DESORBED ORGANIC COMPOUNDS INTO A REFLUX STREAM WHICH IS RETURNED TO SAID COLUMN AS AFORESAID AND A STREAM WHICH IS RECOVERED AS THE NET EXTRACT PRODUCT.
