Abstract :It is known that supercritical fluid extraction has many advantages over traditional extraction methods. This method, which has a wide application area, attracts the attention of many researchers. Due to its advantageous properties, carbon dioxide is generally used as a supercritical fluid in the studies. For this reason, the number of researchers using supercritical carbon dioxide extraction systems is quite high. These systems are known to include serious hazards such as high pressure. In this study, the hazards of a supercritical CO2 system have been evaluated by using Hazard and Operability (HAZOP) study. The implementation of this method has been carried out as follows: The design intention of the supercritical CO2 extraction system has been explained, guide words have been applied to process parameters to obtain meaningful deviations from the design intent, consequences arising from the deviations have been determined considering that all existing safeguards failed, possible causes of deviations have been listed, existing safeguards have been evaluated and actions have been suggested. As a result of the study, it has been understood that excessive pressure can occur for many different reasons and this excessive pressure can lead to serious consequences. To prevent high pressure hazards and other identified hazards from becoming a risk, some precautions have been proposed. Although the results are not dangerous, the causes of operability problems that may be encountered frequently, have been determined and suggestions have been made. This study will contribute to eliminating the deficiency in the literature on safety in the supercritical fluid extraction process, will help those who use similar systems or designers in terms of both safety and operability problems.
