Abstract
A system is shown for injecting a chemical, such as an odorant, from a chemical supply into a fluid containing system such as a natural gas pipeline or an LPG pipeline. A tank of odorant is maintained at a pressure above ambient, but below the pressure of the pipeline. An injection conduit communicates the odorant tank with the pipeline. A hydraulic pressure booster is located in the injection conduit for pressurizing the chemical to a pressure above that of the pipeline, the hydraulic booster having a first side which communicates with the chemical in the injection conduit and another, isolated side which is exposed to hydraulic pressure but which is isolated from the chemical being injected. A flow control valve may be located within the injection conduit for metering chemical to be injected into the pipeline.
