Abstract
Abstract A CONTINUOUS CHEMICAL REACTION IS CARRIED OUT IN A CLOSED LOOP TUBULAR REACTOR. SPHERICAL SEPARATORS SPACED APART IN THE TUBE DIVIDE THE TUBE INTO CELLS. THE CELLS AND SEPARATORS ARE PROPELLED PAST FIXED STATIONS AT WHICH OPERATIONS ARE PREFORMED WHICH INFLUENCE THE CHEMICAL REACTION. THE REACTION PRODUCTS ARE DISCHARGED AT THE END OF THE TUBE, AND THE SEPARATORS ARE RECOVERED THROUGH A LOCK AND REINTRODUCED AT THE BEGINNING OF THE TUBE.
