4 Supercritical CO2 Extraction The extraction technology in food and pharmaceutical industries are commonly using organic solvent as the extraction agent. But in recent years, many advanced technologies have begun to replace organic solvent with supercritical R744, due to the higher solubility and higher permeability, R744 critical temperature is closer to the ambient temperature (31.7°C), and rare chemical reaction with the extraction substances. With all the above mentioned advantages, supercritical CO2 is one of the most important developments in many industries and countries. KAORI latest high pressure C series plate heat exchanger is the best solution for supercritical extraction, as a gas-cooler or sub-cooler. Comparing to traditional heat exchangers, KAORI C series has smaller model size, higher heat transfer performance, and easier installation. Hence KAORI C series is chosen by manufacturers of CO2 Extraction technology system.

To find an alternative and environmentally friendly medium, many car dealers are gradually introducing R744 (CO2) into their new vehicle air conditioning system for replacing HFO. Non-flam- mable characteristics, with only 1 GWP value, R744 (CO2) is more environmentally friendly and a safer refrigerant for vehicle air conditioning system. KAORI C series plate heat exchangers are dedicated for R744 (CO2) applications. C series working pressure could be customized up to max. 140 bar, with advantages of high thermal efficiency, and compact and lighter model, it is truly the best component for vehicle CO2 refrigeration system.
