Why is dry desulfurization given priority?

Thread Content

With the rapid development of China’s chemical industry, the treatment of the hazardous substance sulfur has gradually been divided into two main categories: dry desulfurization and wet desulfurization. So what is the difference between the two? The main difference between dry and wet methods: In the dry method, the desulfurization agent reacts with SO2 in the flue gas to produce calcium sulfate ； By using electron beam irradiation or activated carbon adsorption to convert SO2 into ammonium sulfate or sulfuric acid, the advantages include a simple process, no issues related to wastewater or acidic waste treatment, low energy consumption. In particular, the temperature of the purified flue gas is high, which facilitates its dispersion through the chimney and prevents the formation of \"white smoke.\" The purified flue gas does not require further heating, and it has low corrosivity. Wet flue gas desulfurization is characterized by the desulfurization system being located at the end of the flue, after the dust collector; the reaction temperature during the desulfurization process is below the dew point, which means that the flue gas after desulfurization needs to be reheated before it can be released. Since it is a gas-liquid reaction. Wet flue gas desulfurization presents problems with wastewater treatment, requires a high initial investment, and also incurs high operating costs. Dry flue gas desulfurization is a gas-phase reaction; compared to wet desulfurization systems, it features simpler equipment, less floor space, lower investment and operating costs, easier operation, lower energy consumption, easier disposal of by-products, and no need for a wastewater treatment system. Our company has been engaged in gas desulfurization for 18 years, boasting extensive experience in this field as well as the capabilities to produce and sell related products. Our main products include: [iron oxide desulfurizer], [sulfur dioxide desulfurizer], [desulfurizer specifically for biogas], [desulfurizer designed for oil refineries], [hydroxyl iron desulfurizer], [hydroxyl iron powder], [powdered activated carbon], [inert porcelain balls], [activated carbon desulfurizer], [zinc oxide desulfurizer], [flue gas desulfurizer], and [high-efficiency ferromanganese desulfurizer]. Our products are widely used in the removal of sulfur-containing gases in natural gas, oil and gas fields, biogas, coal chemical industries, coking plants, landfills, and other similar applications. One-stop services for desulfurization projects are provided: technical consultation—solution design—engineering technical services—lifelong after-sales support—collection of waste agents on behalf of clients.
