Abstract

The invention relates to a tower-top cyclone purification method and a device for a recycling hydrogen desulfurization tower. The invention provides a tower-top cyclone purification method for a recycling hydrogen desulfurization tower, which comprises the following steps: carrying out a countercurrent contact reaction between sulfur-containing mixed gas entering the recycling hydrogen desulfurization tower and absorption liquid in the recycling hydrogen desulfurization tower, sequentially performing countercurrent absorption and cyclone absorption on the sulfur-containing mixed gas so as to remove sulfur in the mixed gas, and obtaining the mixed gas with the absorption liquid; and performing gas-liquid cyclone separation on the mixed gas with the absorption liquid so as to obtain the purified mixed gas. The invention also provides a tower-top cyclone purifying device for the recycling hydrogen desulfurization tower.

Description

technical field [0001] The invention relates to a treatment method for removing liquid phase components from a mixed gas of a desulfurization tower, in particular to a method for swirling and removing absorption liquid (ie, amine liquid) components from a sulfur-containing circulating hydrogen mixed gas. The invention also relates to a device for removing liquid phase components from the mixed gas of the desulfurization tower. Specifically, the present invention provides a method and device for purifying swirling flow at the top of a circulating hydrogen desulfurization tower. Background technique [0002] Dry gas, liquid hydrocarbons, and recycle hydrogen operating units are important components of the coker. Since crude oil usually contains sulfur (crude oil from the Middle East-Arab countries is highly sulfur-containing crude oil), dry gas, liquid hydrocarbons, and circulating hydrogen contain hydrogen sulfide (H 2 S). The content of hydrogen sulfide increases with the...
