DATUM® compressors achieve high pressure for low-molecular-weight gas

Hoping to ramp up its production of clean fuel from sour crude, a client invested in a new production process with demanding hydrogen compression requirements. We helped them meet these demands by installing a unique DATUM® solution that consisted of a net gas compressor train with two nine-stage compressors driven by a double-ended variable speed motor with a speed increasing gearbox. This powerful solution generated a total of 275,000 feet of head—a number that would likely require three of our competitors’ compressors.

Key benefits:

  • Achieved high pressure ratios for low-molecular-weight gas
  • 275,000 feet of head with two cases
  • Lower cost and smaller footprint
