## Application of supercritical fluids in integrated process of reactive extraction

### Mateusz Michał Dyngosz

#### Abstract

This paper describes the integrated process of reactive extraction with supercritical fluids and influence of process parameters on rate and efficiency of reactive extraction process, also evaluation if this process can be applied in practice. Process conducted with supercritical fluids was compared with conventional method, which uses organic solvents. This paper includes: review of literature connected with application of supercritical fluids in several industrial areas, investigation of reactive extraction process of citric acid with supercritical fluids and tertiary amine and influence of process parameters (temperature, mixing, time and chain length of tertiary amines) on rate and efficiency of the process. The investigation of the influence of temperature on efficiency of the process were conducted in temperatures: T=308,15K and T=318,15K, and pressure: p=140 bars. The results show that with the increasing of temperature, efficiency of the process decreases in supercritical carbon dioxide (scCO2), same as for conventional method with organic solvents. Experiments on the influence of mixing on the course of this process were conducted at stirrer speed from 200 rpm to 500 rpm. In general, results show that with increased speed, rate of reaction increases. For example maximum efficiency of the process for stirrer speed of 500 rpm was achieved after 5 minutes, and for stirrer speed of 200 rpm maximum efficiency was achieved after 30 min. The investigations of influence of time on efficiency were conducted from 30 seconds to 60 minutes.
