Embodiment 1

[0036] Such as figure 2 As shown, a hydrogenation unit hydrogen joint optimal utilization process, for the hydrogen pressure from the hydrogen pipeline network is higher than the system pressure of the first reaction unit and the second reaction unit, between the hydrogen pipeline network and the first reaction unit 1 can be The supplementary hydrogen compressor is canceled, and the hydrogen from the hydrogen pipeline network 10 directly enters the first reaction unit 1 to carry out catalytic hydrogenation reaction with the raw material oil, and the remaining hydrogen enters the first cold high-resolution unit 3 for gas-liquid separation and is used as the second reaction unit 2 The supplementary hydrogen and the circulating hydrogen of the second cold high-resolution unit 4 are combined and processed by the hydrogen circulation unit 5, and then enter the second reaction unit 2 to carry out catalytic hydrogenation reaction with the raw material oil, and the remaining hydrogen ...

Embodiment 2

[0039] Such as image 3 As shown in Fig. 1, a joint optimized utilization process of hydrogen in a hydrogenation unit, when the pressure of hydrogen from the hydrogen pipeline network is lower than the system pressure of the first reaction unit and the second reaction unit, a hydrogen pipeline is set between the hydrogen pipeline network and the first reaction unit 1 There is a supplementary hydrogen compressor 61. The hydrogen from the supplementary hydrogen compressor 61 first passes through the first reaction unit 1 to carry out catalytic hydrogenation reaction with the raw material oil, and the remaining hydrogen enters the first cold high-resolution unit 3 for gas-liquid separation as the second reaction The supplementary hydrogen of unit 2 and the circulating hydrogen of the second cold high-resolution unit 4 are combined and processed by the hydrogen circulation unit 5, and then enter the second reaction unit 2 to carry out catalytic hydrogenation reaction with the raw m...

Embodiment 3

[0043] Such as Figure 4 As shown in the figure, a hydrogenation unit hydrogen combined optimal utilization process, when the hydrogen supply capacity of the first supplementary hydrogen unit 61 is greater than the hydrogen consumption of the first reaction unit 2, the first supplementary hydrogen unit 61 is divided into the first reaction unit 1 In addition to supplying hydrogen, hydrogen is also supplied to the second reaction unit 2 . The excess hydrogen from the first supplementary hydrogen unit 61 first passes through the first reaction unit 1 to carry out catalytic hydrogenation reaction with the raw material oil. After the reaction, the remaining hydrogen enters the first cold high-separation unit 3 for gas-liquid separation and then is separated with the second cold high-separation unit 3. The circulating hydrogen in unit 2 is processed by the hydrogen circulation unit and enters the second reaction unit 2 together with the hydrogen from the first supplementary hydroge...

Abstract

The invention discloses a hydrogen combined optimized utilization technology of a hydrogenation apparatus. Excessive hydrogen from a hydrogen pipe net passes through a first reaction unit and conducts a catalysis hydrogenation reaction with raw oil; residual hydrogen enters a first cold-high pressure separating unit for gas-liquid separation, then mixes with cycling hydrogen from a second cold-high pressure separating unit, is treated by a hydrogen cycle unit and enters to a second reaction unit to conduct a catalysis hydrogenation reaction with raw oil; residual hydrogen enters into the second cold-high pressure separating unit for gas-liquid separation, merges with residual hydrogen from the first cold-high pressure separating unit, is treated by the hydrogen cycle unit and returns to the second reaction unit. According to the technology of the invention, two sets of hydrogenation apparatuses can share a new hydrogen machine or a hydrogen cycle compressor and part of pipes, so as to reduce equipment quantity and energy consumption of the new hydrogen compressor and the cycle hydrogen compressor, and realize small investment and low cost.

Description

Technical field [0001] The present invention involves a hydrogen use process for hydrogenation device, which specifically involves a hydrogenation device hydrogen optimization and utilization process. Background technique [0002] The hydrogenation device in the petrochemical industry mainly uses the action of the hydrogenation reaction of the hydrogenation of the hydrogenation catalyst in the hydrogenation reactor under a certain temperature and pressure.The hydrogenation device is mainly divided into two types: hydrogen refined device and hydrogenation device. The hydrogen refined device is mainly device for the purpose of removing impurities of hydrogenation impurities of raw materials.As well 2 S, NH 3 H 2 O and remove, the metal is cut in the catalyst. At the same time, the olefin and aromatics in the oil products are saturated with hydrogenation;Cracking and heterogeneous reactions are transformed into light oil devices.The sulfur, nitrogen, oxygen and other impurities are ...
