Koch 1400 Helium Compressor Pump

This unit has some parts to the controller that need to be reconnected. Was reported to be working, we have not been able to test it due to our lack of knowledge and our lack of understanding of this type of compressor. The CTI-4000 re-commissioning is currently underway. Capacity upgrades include reutilizing the internal nitrogen precooling safely, increasing process pressure by recertifying two limiting pressure vessels to a higher MAWP, and adding a 3-inch reciprocating wet engine to the final expansion into the two-phase region. The process was modeled in EES by performing a first law analysis with mass balance and taking key parameters from the original T-S diagram. The model predicts the liquefier capacity could more than double with the upgrades, where the capacity increased from 5.5 g/s in J-T mode at 14bara to ~11.75 g/s in WE mode at 18 bara.
