Problems solved by technology

Since the hydrogenation process is an exothermic reaction, the feedstock oil is unevenly distributed on the radial section of the catalyst bed, which will lead to different reaction degrees and radial temperature differences, and even local overheating, which will damage the performance of the catalyst and greatly reduce the catalyst performance. life cycle

Embodiment 1

[0043] Compared with Comparative Example 1, Example 1 adopts the hydrogenation reactor of the present invention, and the flushing reduction and equalizing plate of the present invention is arranged in the upper head of the hydrogenation reactor, using such as figure 2 The flush reducing and equalizing plate shown is used in combination with a common ERI type bubble cap gas-liquid distributor. The parameters of the fouling plate are as follows: the height of the folded edge set on the flush-reducing and equalizing plate is 80 mm. The slits set in the hemming of the impulse reducing and equalizing plate are semi-circular. The height from the bottom edge to the top edge of the seam is 1 / 2 the height of the hem. The total area of ​​slits on the folded edge of the shock-reducing disc is 1 / 3 of the total area of ​​the folded edge. The height of the outer cylinder of the scaler is 400mm. The height of the inner cylinder is 100mm higher than the height of the outer cylinder. The ...

Embodiment 2

[0045] The same as Example 1, the difference is that the conventional ERI type gas-liquid distributor in the field in the original hydrogenation reactor is cancelled, and only the toothed weir type flush-reducing and equalizing flow plate provided in the present invention is retained, and the bed diameter See Table 1 for the temperature and temperature difference.

Abstract

The invention discloses a hydrogenation reactor with a buffer element. The fixed-bed hydrogenation reactor of the present invention comprises a material inlet pipe, an inlet diffuser, an upper head of the reactor, a flow-reducing equalizer plate, a catalyst bed, a catalyst support grid, a reactor cylinder, a lower head of the reactor, Outlet collector, material outlet pipe and unloading pipe. The shock-reducing flow-distributing plate is set in the idle space of the upper head of the reactor, or above the top of the reactor cylinder and the top distribution plate; the described shock-reducing flow-distributing plate is provided with several distributors, including Disc, material drop pipe and connecting rod, the flow sharing plate and material drop pipe are connected by connecting rod. The hydrogenation reactor of the invention is suitable for the hydrofinishing or hydrocracking process of oil products.

Description

technical field [0001] The invention relates to a hydrotreating reactor with a flushing element, belonging to the field of chemical equipment, in particular to a hydrotreating reactor suitable for oil hydrorefining or hydrocracking treatment. Background technique [0002] In recent years, with the rapid economic development and the enhancement of environmental protection awareness, the quality and environmental protection requirements of petrochemical products are getting higher and higher. As a technical means to produce clean fuels, hydrogenation technology plays an increasingly important role in the refining industry. In the hydrogenation unit, like the hydrogenation catalyst technology and the hydrogenation process technology, the hydrogenation reactor technology is an important part of the reactor system, and the three constitute the three factors of the reactor performance. In the hydrogenation unit, the hydrogenation reactor, which is the key equipment, completes the...
