Abstract

The invention provides a desulfurization tower used for desulfurizing of hydrogenation dry gas. The desulfurization tower comprises a tower body, a first material filling assembly and a second material filling assembly, wherein the tower body is provided with a desulfurizing reaction chamber, a desulfurizing agent inlet and an air outlet which communicate with the desulfurizing reaction chamber are formed in the upper end of the tower body, a desulfurizing agent outlet and an air inlet which communicate with the desulfurizing reaction chamber are formed in the bottom of the tower body, the first material filling assembly and the second material filling assembly are sequentially arranged in the desulfurizing reaction chamber from top to bottom, thus a desulfurizing agent sequentially flowsthrough a first material filling layer of the first material filling assembly and a second material filling layer of the second material filling assembly from top to bottom, and reacts with the hydrogenation dry gas flowing from bottom to top on the first material filling layer and the second material filling layer in a contact mode, and thus desulfurizing is conducted on the hydrogenation dry gas. According to the desulfurization tower used for desulfurizing of the hydrogenation dry gas, the problems of low desulfurization load and poor desulfurization capacity of a desulfurization tower in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a desulfurization tower. Background technique [0002] The oil product upgrading system is widely used in refineries because it can effectively improve the quality of oil products. The oil product upgrading system includes gasoline desulfurization units, diesel desulfurization units, hydrocracking units, and hydrofining units. The raw material of the hydrogen production unit: hydrogenated dry gas, and the hydrogenated dry gas directly produced by the above-mentioned device contains a large amount of sulfur; therefore, in order to fully recycle the hydrogenated dry gas, it is necessary to pass the hydrogenated dry gas into The desulfurization tower performs desulfurization. [0003] Existing desulfurization towers usually have a multi-layer tray structure, and the desulfurization load of this structural type of desulfurization tower is relatively low. The desulfurization...
