Why use Supercritical carbon dioxide instead of water and steam

Why use Supercritical carbon dioxide instead of water and steam

We know that since Watt invented the Steam engine, fire and water have been leading the process of heat, machinery, electricity and energy conversion. Watt's Steam engine uses coal to burn water, converts it into steam, pushes the piston to move, and generates mechanical power. Now, this principle is also used for thermal power generation, by causing the piston to move back and forth to rotate the turbine, to drive the generator set or use a Stirling engine for power generation. So, why use Supercritical carbon dioxide instead of water and steam?

State of the art of Supercritical carbon dioxide solar thermal power generation

State of the art of Supercritical carbon dioxide solar thermal power generation

The Supercritical carbon dioxide cycle power generation system is an advanced thermal power conversion technology. It uses Supercritical carbon dioxide as the working medium to work in a closed thermal cycle. When the heat source temperature exceeds 500, the Supercritical carbon dioxide cycle is suitable for the heat source temperature. It can use 400-700 heat sources, and the cycle efficiency is as high as 40% -50%. With a compact structure, it can achieve 10-20MWe modular design. Then, let's take a look at the State of the art of Supercritical carbon dioxide solar thermal power generation.

Application of Supercritical CO2 Extraction Technology in Plant Extracts

Application of Supercritical CO2 Extraction Technology in Plant Extracts

The supercritical CO2 extraction technology not only allows for one-time deacidification, decolorization, and deodorization in the extractor, but also uses CO2 as the extraction agent, ensuring environmental protection and no residue characteristics. Compared with traditional extraction methods, SFE has great advantages in the extraction of plant extracts and essential oils in terms of purity, yield, content of Active ingredient, color, aroma, etc. of plant extracts.
