  Abstract

In this study, we observed the oxygen removal process, which is the initial control process during CA storage, to identify the factors affecting precise gas environment control and to secure theoretical basic design data. For this purpose, the PSA-type nitrogen generator and carbon dioxide scrubber were connected to the airtight storage by exhaust and circulation-type, respectively, and the oxygen removal process was observed from the atmosphere (O2 21%) to 2%. The operating conditions of the CA system were divided into the presence or absence of cooling operation for temperature control, single operation of the nitrogen generator, and combined operation of the nitrogen generator and carbon dioxide scrubber. In addition, the basic data needed for the design was obtained by comparing the results of the gas replacement prediction formula calculation with the experimental results. As a result, the oxygen control time of the low oxygen (5-2%) section according to the operation of the cooling device was 34 and 99 hours, respectively, and the outside air inflow effect by the cooling operation was confirmed. At this time, the carbon dioxide scrubber was predicted to be the same performance as the nitrogen supply of 6 N㎥/h.
