Supercritical fluid technology stands for processes that are performed at temperature and pressure either near or above the critical point of a substance. One of the most popular applications in 1970 was supercritical fluid extraction, which is also known as gas extraction. This is because of the use of CO2 at temperature and pressure above the critical point. For several applications, this supercritical fluid technology is worthwhile at the industrial scale. Through this blog, you will learn about the construction of SFE Equipment.
Equipment setup:
In equipment setup, the first step is constructing supercritical fluid extraction 0.1L unit is gathering of the component support structure. Moreover, the mainframe of supercritical fluid extraction 0.1L contains 4 pieces of 800mm, 5 pieces of 710 mm, and 7 pieces of 510 mm. These pieces units are attached to the primary structure and the two steel plates are designed based on the previous design. After that, all of the components are located with the objective of easy accessing the extractor, valve panel, separator, and process indicator.
Two raw materials, annatto, and sweet fennel are used to validate the equipment. The annatto is used to validate the extraction line without a separator. On the other hand, fennel is used to validate the extraction monitored by separation.
Extraction and separation
The extractor of critical fluid extraction 0.1 unit has a volume of 100 mL and an internal diameter relationship of 19. However, the two separators have a 90 mL volume, with a lateral entrance equipped with thermocouples that reach half the height of the cylinder. And permit estimates of the good boundary conditions and the temperatures at the central points of the cylinders. The extract masses are weight, and the yield after extraction is calculated as the mass of extract divided by the mass of dry basis. Overall extraction curve, which is cumulated mass of extract against the time of extraction and it can interpreted as containing three stages:
The constant extraction rate period
The falling extraction rate period
The diffusion-controlled period
Moreover, the overall extraction curve is adjusted to the spline model containing straight three lines. The funnel extraction is obtained at 200 bar and 313k according to the procedure with a flow rate of 12g/min and S/F of 10. The condition of the first separator is (80 bar, 312 k) and the condition of the second separator is (20 bar, 279K). After one hour of extraction, the extracts are stored at 255 K for late analyses.
Lastly
After reading the above information, you will be able to understand the construction of critical Fluid extraction equipment and its working process & working conditions.
