Title: DEVICE AND METHOD FOR THE ODORISATION OF A GAS CIRCULATING IN A PIPELINE
Abstract:
The invention relates to a device (100) for the odorisation of a gas circulating in a pipeline (200), comprising: a tank (105) for a liquid odorising compound; a means for detecting (140) differences in pressure between the pipeline (200) and the tank; a means (135) for pressurising the compound in the tank according to the pressure difference; a microperforated membrane (110) acting as an interface between the tank and an inner volume (115) of the pipeline; and a means (120) for vibrating the microperforated membrane in order to spray the liquid odorising compound, when it comes into contact with the membrane, into the pipeline.
