AI Technical Summary
Technical Problem
Existing cryogenic fluid distribution stations suffer from significant fluid loss and pressure risks due to venting of residual hydrogen during thermalization and refilling operations, leading to inefficiencies and environmental impact.
Method used
A distribution station with a transfer line comprising a main circuit and a return circuit allows for the reuse of residual cryogenic fluid, incorporating a compression system with asynchronous pumps and a branch line for fluid recycling, along with a controller to manage valve operations.
Benefits of technology
Reduces fluid loss and pressure risks by recycling residual cryogenic fluid, enhancing efficiency and reducing environmental impact while maintaining safety and cost-effectiveness.

Abstract
The invention relates to a pressurized fluid distribution station (100) such as hydrogen, comprising a transfer line (TL) connecting in this order a source (10) of a cryogenic fluid, a cryogenic fluid compression system (20), and a distributor (30) configured to distribute the cryogenic fluid to a tank (8) to be filled, the transfer line (TL) comprising a first circuitry (L1) configured to ensure a flow of a gaseous stream of the cryogenic fluid from a first zone of the source (10) to a first region of the compression system (20), and vice versa, a second circuitry (L2) configured to ensure a flow of a liquid stream of the cryogenic fluid from a second zone of the source (10) to a second region of the compression system (20), and vice versa, and a third circuitry (L3), called the main circuitry,configured to ensure the flow of a stream of cryogenic fluid from an outlet of the compression system (20) to the distributor (30). According to the invention, the distribution station (100) comprises a branch line (L4) from the transfer line (TL) at the compression system (20), the branch line (L4) comprising a first end connected to the first circuitry (L1) at a first junction point JP1 located upstream of the compression system (20), and a second end connected to the main circuitry (L3) at a second junction point JP2 located downstream of the compression system (20).
