DEVICE AND METHOD FOR INJECTING DIHYDROGEN INTO A FLOW OF NATURAL GAS ORIGINATING FROM A FIRST NATURAL GAS DISTRIBUTION NETWORK

摘要

The device (10, 20, 30) for injecting dihydrogen into a flow of natural gas originating from a first natural gas distribution network (105) comprises: a gas pipe (110) for connecting to the first distribution network through which a flow of natural gas passes, a pipe (115) for feeding dihydrogen, comprising a reservoir (120) for intermediate storage of dihydrogen, a sensor (125) for sensing the flow rate of the flow of natural gas passing through the connecting pipe, said sensor providing a signal representative of the flow rate measured, a means (130) for regulated injection of the dihydrogen stored in the reservoir for intermediate storage into the gas passing through the connecting pipe, depending on the flow rate measured, a sensor (185) for sensing at least one characteristic of a composition of the gas mixture, and a means (135) for feeding the mixture of natural gas and dihydrogen, injected at a second natural gas distribution network (140), depending on each characteristic of the sensed composition of the mixture.
