Small extraction equipment manufacturer: CO2 supercritical extraction refrigeration effect

Small extraction equipment manufacturer: CO2 supercritical extraction refrigeration effect

Small extraction equipment manufacturers: Similar to supercritical extraction, subcritical conditions refer to the conditions in which substances exist. Some substances have a higher boiling point but lower than the critical temperature, exist as a fluid, and the pressure is lower than the critical pressure. When the temperature does not exceed a specific value, pressurized gas can be liquefied, but above this temperature, no matter how much pressure is applied, gas cannot be liquefied. This temperature is called the critical temperature of this gas. The pressure required for liquefied gases at critical temperatures is called critical pressure.

Do you know about the supercritical CO2 extraction process and its influencing factors?

Do you know about the supercritical CO2 extraction process and its influencing factors? The process flow of supercritical CO2 extraction varies according to different extraction objects and tasks. It is generally divided into an extraction section and a separation section, where the extraction section refers to the transfer of solute from the raw material to the carbon dioxide fluid, and the separation section refers to the separation of solute and carbon dioxide, as well as the separation between different solutes. In the process of supercritical CO2 extraction, we are also affected by many factors, which requires us to use different extraction processes for operation. These impacts mainly include:

The Conceptual Characteristics and Applications of Supercritical Water

The Conceptual Characteristics and Applications of Supercritical Water

274 ℃, 2.18 × At 10 ^ 7Pa, it is the critical point for pure water, and supercritical water refers to the water that exceeds this critical point. Supercritical water is often presented in a gaseous state, but its properties are greatly different from low-pressure water vapor and liquid state, and naturally there is no coexistence of liquid and gas. When in the state of supercritical water, inorganic substances are almost insoluble, but organic substances can dissolve (during this process, organic substances have been oxidized and destroyed). When this phenomenon is applied, it can be developed into supercritical water oxidation (SCWO) technology, which is used to treat various toxic chemicals in waste gas, wastewater, and solid waste

How to Understand Supercritical Water in a Lifelike Language

How to Understand Supercritical Water in a Lifelike Language

This small issue can be said to have been bothering me all along, and now I will explain it in detail. We all know that in our daily lives, we can divide the substances we see into solid, liquid, and gas.

Carbon dioxide extraction equipment can be used to extract volatile elements

Carbon dioxide extraction equipment can be used to extract volatile elements

Critical liquid was first discovered in 1822. The gases tested at that time were triafluoromethane, ethane, Nitrous oxide, Sulfur hexafluoride and propane. Finally, people chose carbon dioxide extraction equipment to extract volatile elements, which can be used for flavoring, perfume production and treatment.

What are the benefits of supercritical extraction?

What are the benefits of supercritical extraction?

Supercritical fluid is a kind of supercritical fluid, which is neither gaseous nor liquid state between gas and liquid. This kind of material can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is larger, similar to that of liquid, and its viscosity is closer to that of gas. So supercritical fluid is an ideal extractant.
