Company: Dow Chemical
Case #: 13


Customer requirement for ethylene gas at elevated pressures without contamination from hydrocarbon type lubricants.

Customer's Need:

Single stage compressor unit to compress ethylene gas using a food grade lubricant.

ACI's Solution:

ACI selected a two throw, six inch stroke Superior frame and applied two custom engineered, four valve cylinders. Distance pieces and oil slingers on the piston rods prevented the migration of crank case oil from the sump into the cylinders. The cylinders featured all of the advanced design features associated with ACI cylinders and related components. The cylinders, with the use of new large bore liners readily offer an increased throughput to meet the customers future requirements.
