SYSTEM FOR MONITORING SUPERCRITICAL FLUID PROCESSES

摘要

A system for monitoring and obtaining spectral data from a supercritical fluid process. The system includes a process vessel containing a supercritical fluid, a light source, and a spectrometer. Sampling light emitted by the light source is transmitted into the internal cavity of the process vessel and reflected back to the spectrometer for processing and analysis. The reflected sampling light includes spectral data about the supercritical fluid, thereby allowing process parameters such as the concentration levels of the fluid in the vessel to be generated and monitored for determining the progress of the reaction. Carbon dioxide may be used as the supercritical fluid, in one embodiment, the system may be used in a supercritical fluid textile dyeing process to monitor the progress of the textile colorization.
