The density is then increased by isobaric cooling for recycling. Operation of supercritical fluid extraction system is controlled from a PC
The isobaric cooling process is used to increase the density of the supercritical fluid in order to facilitate recycling. This cooling process is carried out while maintaining constant pressure, hence the term "isobaric". By decreasing the temperature of the supercritical fluid, its density increases, making it easier to separate and recover solutes from the mixture.
The operation of the supercritical fluid extraction system is controlled from a PC (personal computer). The PC is likely equipped with software and an interface that enables the user to monitor and control various parameters of the extraction process. This may include setting the desired pressure, temperature, and flow rates, as well as monitoring and recording data such as extraction efficiency and system performance. The PC interface provides a user-friendly and efficient way to manage the entire extraction process, ensuring optimal control and accuracy.
