Embodiment 1
[0035] The application of two reactors in the "200,000 tons / year catalytic cracking gasoline hydro-upgrading unit". The design parameters of the two reactors are as follows:
[0036] One-stage reactor: operating pressure 2.55MPa, operating temperature 430°C, medium gasoline, hydrogen, specification size φ1400×19190×34.
[0037] Second stage reactor: operating pressure 2.65MPa, operating temperature 430°C, medium gasoline, hydrogen, specification size φ2400×16450×54.
[0038] The specific design steps are as follows:
[0039] According to the above parameters, it is calculated by the professional reaction of the process that the gas-liquid two-phase flow characteristics of the two reactors are basically the same during operation, the mass flow rate of the liquid phase flow is greater than that of the gas phase flow, and the flow rate between each bed of the catalyst The gas-liquid two-phase flow velocity is small, and the liquid phase flow ρv 2 =210~260kg / (m.s 2 ), gas phas...
