Embodiment 1
[0038] Example 1: as Figure 1-Figure 3 As shown, the oil and gas recovery method of the oil tanker terminal of the present invention comprises the following steps:
[0039] (S1) The oil and gas to be treated sent from the oil and gas inlet is sent to the oil and gas system, and passes through the regenerative heat exchanger, pre-cooling heat exchanger, shallow cooling heat exchanger, deep cooling heat exchanger and gas-fluorine exchange in the oil and gas system in turn The heat exchanger liquefies the oil and gas by exchanging heat with the refrigerant sent from the refrigeration system, and the oil and gas treated by the gas-fluorine heat exchanger is sent to the regenerative heat exchanger again, and is discharged after heat exchange in the regenerative heat exchanger;
[0040] (S2) The refrigeration system includes a primary refrigeration system, a secondary refrigeration system and a tertiary refrigeration system; the primary refrigeration system sends the refrigerant to...
