Abstract:
1. A system ( 30 ) for continuously producing a liquid product (P) comprising at least two liquid components (k 1 , k 2 ) that are capable of being pumped, with a first and a second storage tank ( 1 a , 1 b ) for each component (k 1 , k 2 ) and a first and a second mass-flow control circuit ( 2 a , 2 b ) attributed to the first and the second storage tank ( 1 a , 1 b ), respectively, for establishing a target mass flow of the component (k 1 , k 2 ), wherein a first and a second supply device ( 3 a , 3 b ) pumps the component (k 1 , k 2 ) out of the respective storage tank ( 1 a , 1 b ) into the respective mass-flow control circuit ( 2 a , 2 b ), and a first and a second flow meter ( 4 a , 4 b ), respectively, for measuring a current mass-flow of the component (k 1 , k 2 ) and a first and a second regulating valve ( 5 a , 5 b ), respectively, for adjusting the current mass-flow are installed downstream following each other in a supply direction (F) of the component (k 1 , k 2 ), wherein a switch arrangement ( 14 a , 14 b ) is provided for each mass-flow control circuit ( 2 a , 2 b ), which on the one hand returns the component (k 1 , k 2 ) to the corresponding storage tank ( 1 a , 1 b ) in case of a deviation of the current mass-flow from the respective target mass-flow and on the other hand feeds the component (k 1 , k 2 ) into a first line ( 9 a ) at a first end ( 24 a ) in case of a match of the current mass-flow with the respective target mass-flow, which first line ( 9 a ) is connected with a second line ( 9 b ) for feeding carbon dioxide and is connected at a second end ( 24 b ) with a filling tank ( 1 c ), wherein the first line ( 9 a ) feeds the liquid product (P) containing carbon dioxide into the filling tank ( 1 c ), from which filling tank ( 1 c ) non-continuous amounts of the liquid product (P) are withdrawn via a filling line ( 22 ), wherein the storage tanks ( 1 a , 1 b ) and the filling tank ( 1 c ) are designed as pressure vessels and are interconnected by means of at least one pressure equalization line ( 1 ) for establishing a pressure equalization between the storage tanks ( 1 a , 1 b ) and the filling tank ( 1 c ) and form together with the pressure equalization line ( 1 ) a pressure equalization system.
