After further processing through the first or second receiving tank, the air in the first palm oil tank V-2206, the first biodiesel tank V-2208, and the first oil tank V2210 is discharged through the nitrogen source. This ensures that when petrochemicals are stored in the first palm oil tank V-2206, the first biodiesel tank V-2208, and the first oil tank V2210, air can react with the air, further ensuring the purity of the petrochemicals.
