This paper describes the design and modeling processes for a testbed developed to evaluate the performance of helium compressors, essential components in a 5 TPD hydrogen liquefaction plant. The compressor operates under inlet of 7.0 bar and 293.1 K, and outlet of 25.9 bar and 315.1 K, and resulting in a specific energy consumption of 11.42 kWh/kgLH2. The testbed is designed to supply gas, cooling water, and other utilities necessary for compressor operation. Furthermore, the testbed design was validated through static modeling using Aspen HYSYS, which included the compressor's performance curves, surge protection systems, stage-wise speeds, and detailed geometries of intercoolers and aftercoolers. The modeled calculations showed agreement within a 5% error compared to the testbed's design values.
