1. Introduction to Supercritical Water Reaction

Supercritical water reaction technology is rapidly gaining attention in various industries due to its unique properties and capabilities. This innovative extraction method utilizes water at supercritical conditions—where it exhibits both liquid and gas properties—to effectively extract valuable compounds from a wide range of materials. As industries seek more sustainable and efficient extraction methods, supercritical water reaction equipment offers a promising solution.

2. What is Supercritical Water?

Supercritical water is water held at temperatures and pressures above its critical point, typically around 374°C (705°F) and 22.1 MPa (3200 psi). In this state, water becomes a supercritical fluid, where it can dissolve a range of organic and inorganic materials. This unique property allows it to act as both a solvent and a reactant, making it an ideal medium for extraction processes.

3. Mechanism of Extraction Using Supercritical Water

The extraction process using supercritical water involves several key mechanisms. These mechanisms are influenced by critical parameters that affect the efficiency and efficacy of the extraction.

3.1 Critical Parameters in Supercritical Water Extraction

Several critical parameters determine the success of supercritical water extraction, including temperature, pressure, and flow rate. The temperature must be high enough to maintain supercritical conditions, while the pressure must be sufficient to keep water in a supercritical state. Additionally, the flow rate affects the contact time between the supercritical water and the material being extracted.
