LH-2001 Sulfur Transfer Agent Regeneration Flue Gas Desulfurizer Highly Efficient Flue Gas Desulfurization

Product description

Regenerated flue gas desulfurizer is also called sulfur transfer agent. Its function is to reduce SOx emissions in flue gas to meet environmental protection requirements. Regenerated flue gas desulfurizer is an important environmentally friendly material which used to treat sulfur dioxide in industrial flue gas. It has many properties that make it an effective tool for reducing atmospheric pollution.

First, the regenerated flue gas desulfurizer has high efficiency. It can quickly convert sulfur dioxide in flue gas into easily processed sulfate, thus reducing the impact on the environment. Compared with traditional desulfurization methods, regenerated flue gas desulfurizer has higher treatment efficiency and shorter reaction time.

Secondly, regenerated flue gas desulfurizer is renewable. It can be recycled and reused through a series of process steps, thereby reducing resource consumption. This not only reduces production costs, but also conforms to the concept of sustainable development. The renewable characteristics of regenerated flue gas desulfurizers have attracted widespread attention and application in the field of environmental protection.

In addition, regenerated flue gas desulfurizer is environmentally friendly. It uses physical adsorption and chemical reaction to remove sulfur dioxide in flue gas without producing harmful by-products.Therefore, the use of recycled flue gas desulfurizer for desulfurization can effectively reduce the emission of air pollutants, improve air quality, and protect people's health. In addition, the regenerated flue gas desulfurizer has a long service life.Due to its high efficiency and regenerative characteristics, regenerated flue gas desulfurizer has lower losses during treatment and can be used continuously for a longer period of time.This reduces the need for frequent desulfurizer replacement and lowers maintenance costs.

Besides, regenerated flue gas desulfurizers have a wide range of applications.It can be used for various types of industrial flue gas treatment, including electric power, metallurgy, chemical industry and other industries.

Flue gas components vary greatly under the same process conditions, but the regenerated flue gas desulfurizer has good adaptability and can be optimized and adjusted for different situations to ensure the best desulfurization effect.

To sum up, the regenerated flue gas desulfurizer is an environmentally friendly material that is efficient, renewable, environmentally friendly and has a long service life.It can not only effectively reduce the emission of atmospheric pollutants and improve environmental quality, but also reduce production costs and achieve sustainable development. In industrial flue gas treatment, regenerated flue gas desulfurizer will play a positive role and contribute to building a clean and beautiful environment.

Instructions:

The blank SOx emission mass concentration is below 800mg/m³. Add ~4.0% sulfur transfer agent, the sulfur transfer rate can reach more than 75%, and the SO2 mass concentration can be controlled below 200mg/m³.The total SOx emission mass concentration in the blank flue gas is between 800 and 1200 mg/m³. By adding ~5.0% sulfur transfer agent, the sulfur transfer rate can reach more than 75%, and the SO2 mass concentration can be controlled below 300 mg/m³. Generally, the method of adding quickly first and then adding smoothly is adopted.

Transfer Agent Mechanism:

Sulfur transfer agent is a solid adsorption aid with fluidization properties similar to cracking catalysts. Its mechanism of action is that the sulfur transfer agent selectively catalyzes and oxidizes SO2 in the flue gas under the oxygen-rich atmosphere in the regenerator to generate SO3 and form metal sulfates.The sulfur transfer agent loaded with SO3 enters the riser together with the regenerated cracking catalyst.The sulfur in the metal sulfate is reduced and hydrolyzed in the reaction section and stripping section to generate H2S and enter the FCC gas product, which is recovered by the sulfur recovery device to avoid sulfur being discharged into the atmosphere. At this time, the sulfur transfer agent itself is also reduced and regenerated, and the cracking catalyst deactivated by coke is circulated into the regenerator to resume its role in adsorbing SOx.

Regenerator mechanism:

In the FCC unit, mix the sulfur transfer agent and the catalyst (the sulfur transfer agent accounts for about 2-3% of the total catalyst), enter the system, or add it through the combustion accelerant feeding port.The sulfur transfer agent reacts with SO3 in the regenerator to form metal sulfate.The sulfur transfer agent after sulfate formation is recycled to the reactor together with the catalyst.The sulfur on the sulfur transfer agent is released as H2S or converted into metal sulfide under the reducing conditions of the reactor. Then H2S is converted and released in the stripper, and together with the H2S generated by the cracking reaction, it is used as the raw material for the sulfur recovery unit for sulfur recovery. The desulfurized sulfur transfer agent is recycled to the regenerator and reused.
