Method for non-intermittent provision of fluid supercool carbon dioxide at constant pressure above 40 bar as well as the system for implementation of the method

摘要

The inventive process for the uninterrupted provision of liquid subcooled carbon dioxide at essentially constant pressure greater than 40 bar comprises the following process steps: liquid carbon dioxide is supplied at low pressure; the carbon dioxide is charged into a low-pressure tank ( 1 ) and is stored there temporarily; the carbon dioxide is pumped by means of a pump ( 4 ) from the low-pressure tank ( 1 ) into a high pressure tank ( 2 ), the pressure of the carbon dioxide being increased; the carbon dioxide is stored or temporarily stored in the high-pressure tank ( 2 ) until removal in a thermodynamic disequilibrium between a liquid phase and a gas phase. The process and the supply system ( 3 ) suitable for carrying out the process are distinguished by their high performance and efficiency for the uninterrupted and inexpensive supply of liquid subcooled carbon dioxide at an essentially constant pressure greater than 40 bar.
