The invention discloses a methanol waste gas recovery process for deodorant extraction production, comprising the following steps: feeding collected methanol waste gas into an absorption tower, carrying out gas-liquid counter-current contact on absorption liquid sprayed out from a tower top at 0-15 DEG C, and discharging methanol-containing rich liquid from a tower bottom; feeding the methanol-containing rich liquid into a distillation tower, carrying out distillation under the condition that the temperature of the tower top is 65-80 DEG C, discharging methanol steam from the tower top, and carrying out cooling and condensing through a first condenser and a second condenser to obtain methanol distillate; and feeding the methanol distillate to the production processes for recycling, cooling the absorption liquid discharged from the tower bottom of the distillation tower to be 0-15 DEG C, and then feeding the absorption liquid into the absorption tower for recycling, wherein the absorption liquid is composed of 85-100% of biological diesel fuel and 0-15% of solubilization modifier. The methanol waste gas recovery process for deodorant extraction production, disclosed by the invention, is simple, capable of saving energy and reducing consumption and high in recovery rate.
