Disclosed is a system for liquefying a volatile organic compound and carbon dioxide. According to an embodiment of the present invention, the system for liquefying a volatile organic compound and carbon dioxide comprises: a volatile organic compound re-liquefying unit; and a carbon dioxide re-liquefying unit. The volatile organic compound re-liquefying unit includes: a compressor which compresses a volatile organic compound generated in an oil storing tank; a cooler which cools the compressed volatile organic compound; a separator which separates the cooled volatile organic compound into a gas-liquid; a moisture remover which removes moisture from a gas-phase component among components separated into the gas-liquid by the separator; and a condenser which cools the volatile organic compound from which the moisture is removed. The carbon dioxide re-liquefying unit includes: a collecting unit which collects the carbon dioxide from exhaust gas; a compressing unit which compresses the collected carbon dioxide; a pre-cooling unit which pre-cools the compressed carbon dioxide; a dehydrating unit which removes the moisture from the pre-cooled carbon dioxide; and a cooling unit which cools the carbon dioxide from which the moisture is removed. The moisture remover and the dehydrating unit share a dehydrator. The present invention can reduce costs of a device.
