Carbon dioxide drying equipment

Supercritical fluid carbon dioxide drying technology is a separation technology of ethanol which has carbon dioxide as the medium. Supercritical fluid drying technology is a new chemical technology developed in recent years. Supercritical fluid is a kind of temperature and pressure above the critical point, without the difference of gas-liquid interface and the substance phase state with the properties of liquid and gas. It has special solubility, variable density and high material exchange rate, making it a superior value as a solvent and dry medium. The key of this technology lies in temperature and pressure control and proper drying rate control. Common drying media include methanol, ethanol, carbon dioxide, etc. In general, supercritical carbon dioxide drying process is adopted: storage tank, pressure pump, extraction heating, extraction, separation heating, separation, gas condensation, circulation
