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.
Claims20
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 coupled directly to the gas pipe, wherein each of the odorant injectors is fed by the liquid odorant with a respective feed circuit under pressure by the common injection manifold, each of the feed circuits being connected to the common injection manifold such that each of the plurality of odorant injectors injects the odorant directly into the gas pipe and each of the plurality of odorant injectors causes the odorant to be atomized in the gas pipe;
- and
- an electronic injection computer that controls the injectors and the high-pressure pump and maintains a pressure difference between the odorant to be injected and the gas in the gas pipe such that an instantaneous atomization of the odorant is caused upon directly injecting the odorant into the gas pipe.
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 odorant injectors coupled directly to a gas pipe;
- feeding each of the odorant injectors with the liquid odorant with a respective feed circuit under pressure by the common injection manifold, each of the feed circuits being connected to the common injection manifold;
- injecting the odorant, by each of the plurality of odorant injectors, directly into the gas pipe, wherein each of the plurality of odorant injectors causes the odorant to be atomized in the gas pipe;
- and
- controlling the injectors and the high-pressure pump using an electronic injection computer and maintaining a pressure difference between the odorant to be injected and the gas in the gas pipe such that an instantaneous atomization of the odorant is caused upon directly injecting the odorant into the gas pipe.
