Design and Commissioning of a Medium-Scale Hydrogen Liquefaction Plant
Abstract This study presents the design and commissioning of a medium-scale hydrogen liquefaction plant of 1.5 tons of liquid hydrogen (LH 2 ) per day (TPD), utilizing a helium Brayton refrigeration cycle with Liquid nitrogen(LN 2 ) pre-cooling. The specific energy consumption (SEC) of the plant was calculated to be 17.1 kWh/kg LH 2 . An exergy analysis was performed to identify the processes within the plant that contribute most to exergy destruction. The analysis revealed that the exergy efficiency of this plant is 15.1%, The commissioning and performance tests were conducted, the measured hydrogen liquefaction rate is 1.59 TPD, the SEC is 15.1 kWh/kg LH 2 , and the Para-H 2 content in the liquid hydrogen output is 98.6%.
