Carbon dioxide is gaining popularity among coffee manufacturers looking to move away from classic decaffeinating solvents. sCO 2 is forced through the green coffee beans which are then sprayed with water at high pressure to remove the caffeine. The caffeine can then be isolated for resale (e.g. to the pharmaceutical or beverage manufacturers) by passing the water through activated charcoal filters or by distillation, crystallization or reverse osmosis. Supercritical carbon d… WebThe triple point is −56.6°C and 5.11 atm, which means that liquid CO 2 cannot exist at pressures lower than 5.11 atm. At 1 atm, therefore, solid CO 2 sublimes directly to the vapor while maintaining a temperature of −78.5°C, the normal sublimation temperature.
