Abstract
The invention relates to a system and a method for injecting liquid odorant into a natural gas pipe, the system comprising: a tank containing the odorant in liquid form; a high-pressure pump connected to the tank; a common injection manifold fed with liquid odorant by the high-pressure pump; a plurality of odorant injectors fed with liquid odorant under pressure by the common injection manifold for the purpose of injecting the odorant into the gas pipe so as to cause it to be atomized in the gas pipe; and an electronic injection computer for controlling the injectors and the high-pressure pump.

A system for injecting liquid odorant into a natural gas pipe, the system comprising:
- a tank containing the odorant in liquid form;
- a high-pressure pump connected to the tank;
- a common injection manifold fed with liquid odorant by the high-pressure pump;
- a plurality of odorant injectors fed with liquid odorant under pressure by the common injection manifold for the purpose of injecting the odorant into the gas pipe so as to cause it to be atomized in the gas pipe;
- and
- an electronic injection computer for controlling the injectors and the high-pressure pump.
A method of injecting liquid odorant into a natural gas pipe, the method comprising:
- using a high-pressure pump to feed a common injection manifold with liquid odorant coming from a tank, said common injection manifold being connected to a plurality of injectors leading into a gas pipe;
- and
- using an electronic injection computer to control the injectors to inject a predetermined volume of liquid odorant into the gas pipe at a predetermined pressure so as to cause the odorant to be atomized in the gas pipe.
