Shanghai Prime, as an engineering and technology company, also has an environmental materials production and processing base, which enables a close integration and complementarity between engineering projects and core materials production.
Based on this, we can simultaneously provide the following services:
Supply of environmentally friendly materials.
Integrated services such as operation and maintenance(if needed)
Recovery of calcium-based desulfurization byproducts
Assisting the client in achieving closed-loop recycling and comprehensive utilization of by-products.
By-products can be further utilized and formed into a closed-loop recycling system.
The by-products, which are calcium-based, primarily consist of Ca(OH)2. With calcium sulfate (gypsum) as the main component of the final by-product, it can be utilized in subsequent processes such as brick making and cement plants. It can also serve as a raw material for wet flue gas desulfurization, forming a "closed-loop recycling of by-products" (as mentioned in note 1).
Note 1:
Closed-loop recycling of by-products refers to the application of calcium-based desulfurization by-products in alkaline liquid preparation, such as wet flue gas desulfurization, to form a self-contained closed-loop recycling system.
Fixed-bed dry desulfurization agent.
Fixed-bed dry desulfurization principle
The fixed-bed dry desulfurization technology operates within the temperature range of ambient to 350°C. In this process, O2 in the flue gas reacts with the oxidizing catalyst component in the desulfurization agent, oxidizing SO2 to SO3. Subsequently, a gas-solid reaction occurs between SO3 and Ca(HO)2 particles in the desulfurization agent, resulting in the formation of CaSO4 and achieving desulfurization.
Main reaction equation:
SO2 + 1/2 O2 → SO3
SO3 + Ca(OH)2 → CaSO4 + H2O
The desulfurization process is implemented in engineering through a quasi-fixed-bed technology (or intermittent moving bed). Alkali (in this case, calcium hydroxide) and catalyst-containing formed particles are loaded into the desulfurization reactor. The flue gas from industrial furnaces enters the desulfurization reactor through the flue. As the flue gas passes through the desulfurization agent, the sulfur dioxide present in the gas is oxidized to sulfur trioxide, which then reacts with the desulfurization agent and solidifies into calcium sulfate (gypsum). This achieves the purification of the flue gas.
The desulfurizing agent is introduced into the desulfurization reactor from the top of the desulfurization tower and moves downward. Once the reaction is complete, the spent desulfurizing agent is periodically discharged from the bottom of the reactor through a discharge valve. The entire process does not use water and does not generate wastewater. It achieves high desulfurization efficiency and can achieve 100% removal of SO2. It can adapt to fluctuations in flue gas temperature and flow rate. The equipment is simple, the process is straightforward, and the operation and maintenance are easy. The equipment has low investment and operating costs and occupies a small footprint. The desulfurized agent obtained after desulfurization consists of formed particles containing calcium sulfate, which has a stable composition and is not easily decomposed. It can be considered as general solid waste and can be recycled as an industrial raw material.
