Drying and Preservation

Nitrogen gas provided by FourQuest Energy nitrogen pumping equipment provides 99.99% pure nitrogen with a dewpoint of -70˚C.

This clean, extremely dry gas is effective for drying out any pipeline or process system. When combined with high temperatures, the drying time to achieve the required dew point is significantly reduced compared with conventional drying methods.

Because nitrogen gas is inert, it is ideal for filling pipelines or process systems that may go unused for long periods of time—months, even years. By maintaining a positive nitrogen atmosphere inside a pipeline or process system, ongoing corrosion can be reduced and even eliminated, provided the system is dry and there are no leaks present. This service is particularly effective for drying of chemically sensitive systems such as oxygen and hydrogen.
