The present invention discloses a device and method for recovering the coldness of residual liquid in a synthesis gas CO cryogenic separation system, and belongs to the field of chemical process. When the synthesis gas CO cryogenic separation system is shut down and drained, the temperature can reach -190°C due to the large amount of low-temperature residual liquid stored in the cold box. The conventional treatment method is to send the low-temperature residual liquid to the flare gas heater through ambient gasification, and discharge it as room-temperature flare gas after heat exchange with saturated steam. When the amount of low-temperature residual liquid is large, this method takes a long time to vaporize the low-temperature residual liquid; or nitrogen is used to cool and gasify the low-temperature residual liquid to produce low-temperature flare gas, which is then sent to the flare gas heater for heat exchange. This method increases nitrogen loss, increases the load of the flare gas heater, makes its equipment size larger, and increases cost. The present invention utilizes the high-grade low-temperature coldness of the low-temperature residual liquid in the CO cryogenic separation system to convert room-temperature nitrogen into liquid nitrogen for storage and recovery, thereby reducing nitrogen loss, reducing 0.5MPaG steam loss, and reducing flare gas emissions.
