Application of Silicon Carbide Ceramic Membrane

1.Application of silicon carbide ceramic film in high-temperature flue gas purification

Silicon carbide ceramic film has unique advantages in the field of high-temperature flue gas treatment due to its high temperature resistance, corrosion resistance, and thermal shock resistance. For particulate pollutants such as PM2.5, the dust removal mechanism of silicon carbide ceramic membrane is pore screening, interception, adsorption, etc. In addition, silicon carbide film has been widely used in high-temperature dust removal industries such as coal chemical, polycrystalline silicon, and steel.

2.Application of Silicon Carbide Ceramic Membrane in Oil Water Separation

Compared to other oxide ceramic membranes, silicon carbide ceramic membranes have higher hydrophilicity and are more advantageous in oil-water separation. This is because the hydrophilic silicon carbide film has a greater electrostatic repulsion effect on oil, resulting in higher water flux and better anti pollution performance. If silicon carbide flat membrane bioreactors are used to treat oilfield produced water, heavy metals (29% -97%), phenols (up to 100%), benzene derivatives (up to 100%), polycyclic aromatic hydrocarbons (up to 100%), and total organic carbon (96% -98%) can be successfully removed. Compared with polymer flat membrane, the flux of silicon carbide ceramic membrane has increased by more than 50%.

3.Application of Silicon Carbide Ceramic Membrane in Gas Separation

Silicon carbide membranes are widely used in gas separation fields such as hydrogen recovery, nitrogen recovery, acid gas treatment, greenhouse gas capture, and water gas reactions in refineries. They do not require the introduction of phase change processes and have the advantage of low energy consumption. SiC ceramic membrane has the advantages of high separation efficiency, easy operation, stable treatment effect, and good flux recovery after pulse airflow blowback due to its efficient barrier effect, excellent thermal shock resistance, and good high-temperature mechanical strength in this field.
