Abstract
Supercritical carbon dioxide extraction (SFE) is a method of separating substances or groups of compounds by dissolving them in supercritical carbon dioxide and then precipitating them in a separator under subcritical conditions. In order to introduce carbon dioxide into a supercritical state, it is necessary to raise the temperature and pressure above the critical point (31.06°C, 73.8 bar). The supercritical carbon dioxide extraction has been used in the food industry since the 1970s. Currently, the supercritical carbon dioxide extraction is also used in the cosmetics, pharmaceutical and fuel industries. As a solvent, carbon dioxide has many advantages. It is an inert gas, inexpensive, easily available and environmentally friendly. In addition, CO2 is classified as GRAS solvents. It is generally believed that SFE is a relatively expensive extraction method. It is true, however, the supercritical fluid extraction is expensive at the equipment investment stage. However, the operating costs are not high and are comparable to other extraction technologies. It also often happens that the cost of the supercritical carbon dioxide extraction is lower than that of liquid extraction. The cost of manufacturing (COM) includes direct and indirect costs, such as the cost of materials, labor and overhead. However, it may also include other aspects of supercritical fluid extraction, including media and residues utilization. The COM is calculated according to the formula : COM= 0,304FCI + 2,73COL + 1,23(CRM +CWT +CUT).
