Abstract

The invention provides a desulfurization tower for desulfurizing hydrogenated dry gas, comprising: a tower body, the tower body has a desulfurization reaction chamber, the upper end of the tower body has a desulfurization agent inlet and a gas outlet connected to the desulfurization reaction chamber, the tower The bottom of the body has a desulfurization agent outlet and an air inlet connected to the desulfurization reaction chamber; the first packing assembly and the second packing assembly are sequentially arranged in the desulfurization reaction chamber from top to bottom, so as to Make the desulfurizer flow through the first packing layer of the first packing assembly and the second packing layer of the second packing assembly sequentially from top to bottom, and at the first packing layer and the second packing layer Hydrogen dry gas contact reaction, and hydrogenated dry gas desulfurization. The invention solves the problems of low desulfurization load and poor desulfurization capacity of the desulfurization tower in the prior art.

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 Desulfurization tower for 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 effect o...
