CO2 (Carbon Dioxide)Plant
Super Gas Plant
- It is the by-product of alcoholic fermentation, fermentation Alcohol & CO2 are recovered.
- It has varied commercial uses but one of its greatest uses as a chemical in the production of carbonated beverages.
- Liquid carbon dioxide is used as a fire extinguisher because of its anti- flammable properties. The gas works by starving the flames of oxygen, which is the gas that supports burning. Fire extinguishers used to put out electrical fires are specifically filled with liquid carbon dioxide. This is because apart from putting out the fire by eliminating oxygen, the pressurised gas cools the burning surfaces preventing further damage.
- Fog effects: You have seen movies with foggy scenes but they were probably filmed in a sunny desert. Liquid carbon dioxide is used together with fog machines to produce a low-lying fog effect. Liquid CO2 is used to cool theatrical fog produced by the fog machines. The fog remains close to the ground when it is cold but when it warms it disperses evenly. The importance of pressurised CO2 in the food industry cannot be underscored enough. The food industry largely relies on this liquid gas for refrigeration, preservation, storage and softening.
- Cooling agent: Liquid CO2 is used as an important cryogenic cooling agent. It is used directly as a food preserve and in cooling applications where it maintains the food at a constant temperature. Liquid carbon dioxide is also used during the transportation of ice cream. It is preferred because of its high volumetric cooling capacity.
- Softening drinks: Compressed carbon dioxide gas is largely used in the production of soft drinks. Carbonation of drinks first happened by natural fermentation, but today bottled drinks are softened and preserved using pressurised co2. Liquid CO2 is also used to remove caffeine from coffee because it is a versatile solvent.
