Research of cryosystems reservoir–pump

In cryogenic plants, systems involving different combinations of cryogenic pumps and storage vessels are utilized to transport high pressure liquids and gases. Understanding the effective design and operations of such systems, referred to as CSRP (cryogenic system reservoir–pump), is of great interest as they contribute significantly to the capital cost, energy efficiency and operational reliability of the overall plant or facility. Despite the significant use in practice and experience with CSRP in operation, the theoretical basis of their design and criteria for selecting a particular design combination from among the available schemes have been poorly studied in the past. This paper presents the results of research dedicated to elaborating the theoretical basis of CSRP. A mathematical model has been developed and is presented and the model has been validated by experimental testing. The model can be applied to evaluate the efficiency associated with a particular scheme and possible improvements. We believe that this paper provides, for the first time, a theoretical basis for CSRP which can be applied in the design and evaluation of such systems.
