More about the topic.
This fluidized-bed homogeneous crystallization technology is primarily applied in the recovery of heavy metals from wastewater and can also be extended to recover nitrogen and phosphorus from water. Additionally, it can absorb carbon dioxide emitted by stacks and convert it into calcium carbonate through crystallization technology, helping to slow down global warming. By converting waste produced after treatment into reusable resources, this technology embodies the principles of the circular economy.
Traditional heterogeneous crystallization technology for treating heavy metal-containing wastewater results in low-purity crystal grains. In contrast, fluidized-bed homogeneous crystallization technology is more advanced and can effectively process large volumes of heavy metal-containing wastewater and high-water-content sludge, achieving waste recycling and reuse. This technology recovers heavy metals that are harmful to the environment, thereby protecting environmental safety and reducing carbon emissions.
This presentation will also introduce the innovative application of combining carbon dioxide alkaline absorption with fluidized-bed homogeneous crystallization technology. This integrated process transforms carbon dioxide from factory flue gas into carbonate, which then undergoes a crystallization reaction in the fluidized bed, forming calcium carbonate particles with calcium ions. The resulting calcium carbonate crystals are of high purity due to the advanced homogeneous crystallization technology. The absorption liquid used in the crystallization tank is recycled back to the absorption tank for further use, enhancing process sustainability. Furthermore, the calcium carbonate crystal particles can be reused as additives in various industrial processes, contributing to resource conservation and waste reduction. A key strength of this technology is its high carbon dioxide capture efficiency, with the process achieving a cross-sectional area loading of up to 40 kg CO2/m²/hr, demonstrating its effectiveness in capturing carbon dioxide from flue gas streams. Additionally, the granulation mechanism, which is crucial for forming high-quality crystals, will also be introduced.
