Process for inerting a transport pipeline with a cryogen media and system for transporting cryogen media

摘要

The method involves partially filling a storage volume, which is integrated and/or fluid-connected with a transport pipe (2) with a cryogenic medium during conduction of the pipe. Production stop of several sections (5, 9) of the pipe that are fluidically separated from each other is started. The cryogenic medium remaining in the storage volume evaporates. The evaporated medium of low temperature is introduced into the pipe section (9) to generate an atmosphere that comprises high pressure when compared to outside atmosphere. An independent claim is also included for a system for transporting a cryogenic medium in fluid or solid state through a transport pipe.
