CRYOGENIC PIPE FREEZING: SCIENTIFIC FOUNDATIONS FOR A COST-EFFECTIVE AND ENERGY EFFICIENT TECHNIQUE.

Author(s) : WIGLEY D. A.

Summary

THIS IS VERY COMPREHENSIVE PAPER DETAILING THE PROBLEMS, POSSIBILITIES AND DANGERS OF FREEZING PLUGS OF WATER OR OTHER LIQUIDS IN PIPELINES BY THE APPLICATION OF A CRYOGENIC REFRIGERANT. THE BASIC CHARACTERISTICS OF PLUG FORMATION ARE DESCRIBED TOGETHER WITH WARNINGS OF LACK OF COHESION DUE TO FOULING LAYERS ON INTERNAL PIPE SURFACES AND THE BREAKAWAY OF PLUG PORTIONS IN LIQUID FLOW STREAMS. THE EFFECTIVENESS OF PLUGS FOR WITHSTANDING PRESSURE, THE SPEED OF PLUGFORMATION, THE POSSIBLE DEGRADATION OF PIPE MATERIALS DUE TO COLD EMBRITTLEMENT, AND THE OPTIMUM AND SAFE POSITIONS FOR PLUGS RELATIVE TO OTHER PIPE FITTINGS ARE ALL INCLUDED. SO ARE THE SAFETY ASPECTS OF CRYOGEN HANDLING AND THE VENTILATION REQUIRED TO REMOVE CRYOGEN VAPOURS WHICH CAN BE LETHAL. D.W.H.
