Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings:
[0029] as attached figure 1 As shown, the tail gas emission recovery system of this gasoline desulfurization production unit comprises gasoline desulfurization reactor 1, and the top feed line of described gasoline desulfurization reactor 1 connects gasoline pipeline 2 and non-purified air pipeline 3; gasoline desulfurization reactor 1 1. The bottom outlet pipeline is connected to the oil and gas separation tank 4.
[0030] The 4 tank bottom pipelines of the oil and gas separation tank are connected to the refined gasoline pump 12, and the refined gasoline is drawn out and sent to the tank farm through the refined gasoline pump 12; Condensed into a liquid phase for recovery; a control valve 13 is connected to the top pipeline of the oil and gas separation tank 4.
[0031] The rear tank of the cooler 5 is connected to a buffer tank 6, which is used to contain the gaso...
