Abstract
A system for recovering gaseous dihydrogen produced in a distribution duct arranged between a main tank and a dihydrogen consumer device, the distribution duct comprising a pump. The system comprises: an auxiliary tank; a bypass duct, arranged between the distribution duct and the auxiliary tank, downstream of the pump; a valve arranged on the bypass duct; a module for obtaining a temperature of the dihydrogen in the distribution duct, upstream of the pump. A control module of the valve opens the valve when the temperature is greater than a predetermined value and closes the valve when the temperature is less than or equal to the predetermined value.
Claims9
A gaseous dihydrogen recovery system comprising:
- a distribution duct arranged between a main tank and a dihydrogen consumer device, the distribution duct comprising a pump for supplying dihydrogen to the dihydrogen consumer device at a predefined temperature and at a predefined pressure, gaseous dihydrogen being produced by evaporation of liquid dihydrogen in the distribution duct,
- an auxiliary tank,
- a bypass duct arranged between the distribution duct and the auxiliary tank, downstream of the pump in a direction of circulation of the dihydrogen in the distribution duct,
- a first controlled valve arranged on the bypass duct,
- a module for obtaining information representative of a temperature of the dihydrogen in the distribution duct, upstream of the pump, and
- a control module of the first controlled valve configured to open the first controlled valve when the information representative of the temperature of the dihydrogen in the distribution duct is greater than a predetermined value and to close the first controlled valve when the information representative of the temperature of the dihydrogen in the distribution duct is less than or equal to the predetermined value.
A gaseous dihydrogen recovery method, the gaseous dihydrogen being produced by evaporation of liquid dihydrogen in a distribution duct arranged between a main tank and a dihydrogen consumer device, the distribution duct comprising a pump for supplying dihydrogen to the dihydrogen consumer device at a predefined temperature and at a predefined pressure, the gaseous dihydrogen recovery method comprising:
- recovering gaseous dihydrogen from the distribution duct to a bypass duct, arranged between the distribution duct and an auxiliary tank, downstream of the pump in a direction of circulation of the dihydrogen in the distribution duct,
- storing the gaseous dihydrogen in the auxiliary tank,
- obtaining information representative of a temperature of the dihydrogen in the distribution duct, upstream of the pump, and
- controlling a first controlled valve arranged on the bypass duct so as to open the first controlled valve when the information representative of the temperature of the dihydrogen in the distribution duct is greater than a predetermined value and to close the first controlled valve when the information representative of the temperature of the dihydrogen in the distribution duct is less than or equal to the predetermined value.
