(ZA9907050-A)   NOVELTY - Recovery of additional expansion agent from the expansion process of tobacco and other agricultural products comprises withdrawing the expansion agent in the impregnation vessel (12) at the end of the second depressurization step during multi-step depressurization sequence, and transmitting a portion of the expansion agent to low pressure gas tank (16).    USE - For the recovery of additional expansion agent from the expansion process of tobacco or other agricultural products.    ADVANTAGE - The method results in an improved hydrate formation and improved efficiency in the recovery of the expansion agents.
