Abstract
To supply a consumer (13a, 13b) with liquid carbon dioxide with a desired temperature of more than 0° C. and a desired pressure of more than 30 bar, liquid carbon dioxide is taken from a tank (1) in which it is stored at a temperature below the desired temperature and a pressure below the desired pressure. The pressure of the carbon dioxide is increased (3) and subsequently the carbon dioxide is heated to the desired temperature (14a, 14b).
Claims10
A method for the supply of a consumer (13a, 13b) with liquid carbon dioxide with a desired temperature of more than 0° C. and a desired pressure of more than 30 bar, characterized in that the carbon dioxide is taken from a tank (1) in which the liquid carbon dioxide is stored at a temperature below the desired temperature and a pressure below the desired pressure, that the pressure of the carbon dioxide is increased (3, 21) and that subsequently the carbon dioxide is heated to the desired temperature (14a, 14b).
A device for the supply of a consumer with liquid carbon dioxide with a desired temperature of more than 0° C. and a desired pressure of more 30 bar, characterized through
- a tank (1) in which the liquid carbon dioxide is stored at a temperature below the desired temperature and a pressure below the desired pressure,
- a supply line (11) connecting the tank (1) with the consumer (13a, 13b),
- a pressure boosting apparatus (3, 21) to increase the pressure of the carbon dioxide supplied to the consumer and
- a heater (14a, 14b) arranged upstream of the pressure boosting apparatus (3a, 3b) for heating the carbon dioxide.
