Embodiment 1

[0050] Example 1: 45,000 tons / year fuel gas desulfurization unit of the Refining Division of Sinopec Shanghai Gaoqiao Petrochemical Company

[0051] The Refining Division of Sinopec Shanghai Gaoqiao Petrochemical Company adopts the micro-cyclone separation technology for the 45,000-ton / year fuel gas desulfurization unit. Avoid amine liquid foaming and tray blockage, and avoid amine liquid entrainment in desulfurization gas torch gas. The main equipment includes a desulfurization tower, a cyclone dehydrocarbonizer, and a cyclone deaminator.

[0052] The equipment has been running continuously and stably since it was put into use in November 2007. The Refining Division of Sinopec Shanghai Gaoqiao Petrochemical Company calibrated the device for a total of 24 hours from 10:00 on September 10, 2008 to 10:00 on September 11, 2008:

Abstract

The invention relates to a swirl reinforcing method and a device for removing hydrogen sulfide by gas, in particular to a swirl reinforcing method for removing hydrogen sulfide by gas. The method comprises the following steps of primarily carrying out a first swirl separation to mixed fuel gas so as to remove the heavy hydrocarbon components mixed wherein; desulfurizing the mixed gas after removing the heavy hydrocarbon components so as to remove the H2S components mixed wherein; carrying out a secondary swirl separation to the mixed gas after removing the H2S components so as to remove the amine-enriched component mixed wherein, thus obtaining a purified gas. The invention also provides a swirl reinforcing device for removing the hydrogen sulfide by gas.

Description

technical field [0001] The invention belongs to the field of chemical environmental protection, and relates to a method for removing heavy hydrocarbons, sulfur compounds and other components in a mixed gas by adopting a cyclone separator, in particular to a method for removing heavy hydrocarbons, H 2 A method for the S component and the rich amine component. The present invention also relates to the removal of liquid phase heavy hydrocarbons, H from the mixed gas 2 S. A device for rich amine components. Background technique [0002] According to the requirements of the national "Eleventh Five-Year Plan" plan, by 2010, the total national emission of major pollutants will be reduced by 10% compared with the end of the "Tenth Five-Year" period, and correspondingly, the total sulfur emission needs to be reduced by more than 10%. Therefore, in our country, the production of environmentally friendly products - clean fuel is imminent. [0003] When the mixed gas entrains heavy h...
