Natural Gas Chromatograph Liquid Injection System

The Liquid Injection System utilizes a true liquid inject valve to inject a liquid sample into a flowing gas stream. This injection, in effect, lowers the dewpoint of the sample to where it can now be measured by the NGC. Once the sample has been delivered to the NGC it can be measured by a variety of methods.

The Liquid Injection System if fully compliant with GPA 2177, as the liquid sample valve is outside the heated zone (GC). The Liquid Injection System comes as a fully integrated package, including the Liquid Inject panel, pilot valves and controller, in an environmental enclosure.Designed for NGL’s with dewpoint below 100°C/212°F.
