Claim 3:
4. The VOCs recovery system of claim 1, wherein an outlet of the VOCs precooler is connected with an inlet of the VOCs condenser in the VOCs recovery cold box, and an outlet of the VOCs condenser is connected with an inlet of the gas-liquid separator, and
wherein the VOCs gas passes through the VOCs precooler to remove moisture in the VOCs gas and to form a dried VOCs gas, the dried VOCs gas enters the VOCs condenser in the VOCs recovery cold box and exchanges heat with the liquified air and the VOCs gas is condensed into a liquid state to form a gas-liquid mixture, which enters the gas-liquid separator to separate liquid from gas in the gas-liquid mixture.
