Process plant leak testing

During the commissioning of refineries as well as other chemical process plants that handle flammable substances, the facility is pressure tested for leaks and for proper operation of the safety devices. These tests are done in a planned staged fashion, and can sometimes take many months to complete.

The test is usually done with nitrogen, which can be supplied either in cryogenic form but is most often far more economical if supplied by Membrane Nitrogen Generating Units. The MNGU’s can produce the “membrane nitrogen” on site and in limitless quantities, thus facilitating logistics – especially in remote areas.
