Embodiment Construction
[0037] The specific implementation manner of the present invention will be described below in combination with specific implementation examples.
[0038] Such as figure 1 As shown, this embodiment is illustrated by applying the device and method of the present invention to desulfurization and sulfur recovery of syngas in an IGCC power plant. In the IGCC power plant, the coal first completes the gasification process in the gasifier, and generates 2 The crude synthesis gas of S pollutants must be purified and desulfurized before the synthesis gas is sent to the gas turbine for power generation.
[0039] After the synthesis gas from the gasifier is firstly deashed and washed with water, only H is left in the synthesis gas. 2 S pollutant composition, synthesis gas pressure 3.0MPag, temperature 40°C, of which H 2 The content of S component, determined according to the type of coal used, is about 0.147% of the total volume. As shown in the figure, the sulfur-containing synthes...
