The invention provides an ethylene propylene rubber production solvent recovery method comprising the following steps: conveying a pressurized and heated to-be-treated rubber solution to a first flashtank to carry out flash evaporation deacidification and recover a first part of solvent in the to-be-treated rubber solution; and repressurizing and reheating the to-be-treated rubber solution whichis subjected to flash evaporation deacidification and in which the first part of solvent is recovered, and conveying the to-be-treated rubber solution to a second flash tank to carry out flash evaporation so as to recover a second part of solvent. The invention further provides an ethylene propylene rubber production solvent recovery system. The invention aims at providing the ethylene propylene rubber production solvent recovery method and system capable of removing acidic corrosive substances in the to-be-treated rubber solution.
