There are still many problems in supercritical fluid CO2 extraction technology, but it does not mean that supercritical fluid extraction technology cannot be used. With the improvement of material living standards and the increasing emphasis on health, people are more and more advocating “return to nature”, while the demand for “green food” and natural products such as food and spices is increasing, and the quality requirements are also getting higher and higher.
Therefore, the use of new technology to improve product quality and research and development of high-value-added, high-grade, high-quality products is to meet the requirements of the market economy and people’s health. It can be said with certainty that due to the inherent superiority of supercritical CO2 fluid extraction, its application prospect is very broad.
5 major factors determine that CO2 extraction technology will be in urgent demand in the foreseeable future
The following factors determine that supercritical fluid extraction technology will be urgently demanded in the foreseeable future.
- Stricter environmental and food regulatory restrictions;
- Demand for all-natural products;
- Demand for new health foods and medicines;
- The need for green processes;
- In modern society, the restrictions on harmful volatile solvents are becoming more and more stringent, and the residual standards of organic solvents in food and pharmaceuticals are also getting higher and higher so relevant manufacturers have to switch to supercritical CO2 fluid extraction technology.
Some Difficulties in Manufacture of CO2 Extraction Equipment
Supercritical fluid extraction technology is a comprehensive technology and modern science and technology crystallization. It involves technologies in chemistry, chemical engineering, machinery, thermodynamics, and automatic control.
Since supercritical fluid extraction technology still has many difficulties in process, equipment, and engineering and is limited by the current comprehensive technical level of the industry, a lot of work is still needed for the development of this technology. If the design of the device does not solve the problems of fluid mechanics, Problems such as engineering thermodynamics and process scale-up will lead to unstable operation and even failure to start.
Therefore, the importance of supercritical CO2 fluid extraction technology should be understood from a long-term strategic height, and the modern process system theory should be adopted to study the composition of each level of the processing system and the interrelationship and interaction between components, and carry out the process according to certain goals. Optimize, and formulate research plans based on this, increase investment, and strengthen the development and research of the basic theory and application technology of this technology, so that it can be truly applied to industrial production and benefit mankind and society.
