Résumé

Cryogenic tanks for application with cryogenic reciprocating high-pressure pumps have been equipped with thermosiphon, which ensures sufficient hydrostatic pressure head at the pump inlet. However, what the pump requires is sufficient NPSH, which is further influenced with hydrodynamic pressure losses and heat leak during the liquid flow through the pumps. On requests of the industrial gas companies, Chart Ferox, a.s., designed high thermosiphons with well sized inlet and outlet pipes. The paper is dedicated to analysis of the design of the outer piping with respect to its sizing and insulation. The main aim is ensuring the full function of the pump for complete emptying of the tank without any need of controlled increase of pressure in the tank. Recommendations on the design of the outer piping and its insulation are specified. Operation experience validates suitability of the design to the application.
