Embodiment Construction
[0027] Such as figure 1 As shown, the reaction product 1 of propane dehydrogenation to propylene is compressed to 1.2-2.0 MPa (gauge pressure) through the three-stage compression system 2, cooled to 5-10°C through the compression outlet cooling unit 3, and enters the drying system 4, and the reaction product is The water content in the water drops below 1ppm. Under the action of the propylene refrigeration system 28, it is cooled to -35~-20°C by the first-stage refrigerator 5 and then enters the first-stage cryogenic tank 6 for gas-liquid separation. Under the action of the ethylene refrigeration system 9, it is cooled to -95~-85°C by the second-stage refrigerator 8, and enters the second-stage cryogenic tank 10 for gas-liquid separation. After the tank top gas is exchanged, most of it is returned to the reaction as circulating hydrogen 14 Part, the remaining gas is sent out to the device as propane hydrogen 13. The first-stage cryogenic tank liquid phase 12 and the second-s...
