THEORETICAL FOUNDATIONS FOR CONTROLLING THE PROCESS OF EXTRACTION OF PLANT RAW MATERIALS AT HIGH PRESSURES

Abstract

Annotation. This article discusses the technology of extraction of vegetable raw materials for the complete extraction of oils. The issue of process control in the extraction-distillation unit is also being solved. The modern extraction industry is forced to use solvents that not only have a higher extraction capacity, but also do not meet the requirements of quality and fire safety standards. One of the solutions to this problem is the use of liquefied carbon dioxide as an extractant. The process is highly profitable, moretechnologically advanced, allows processing not only high-quality raw materials, but also production waste in order to extract the main components from them to give higher quality to low grades of the product. Extraction with carbon dioxide in a liquefied state significantly expands the range of biologically active compounds released.
