Danmar Industries Custom Engineers for Oil and Gas

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

The items included three 550 horsepower (hp), oil-flooded, water-cooled, single-stage air compressors with inlet valve modulation capable of providing 1,540 scfm at 165 psi (11.4 bar), two heatless desiccant, 3,138 cfm, 165 psi (11.4 bar) compressed air dryers, and two nitrogen generators for the main station, as well as two smaller air compressors and heatless desiccant compressed air dryers for each of three smaller facilities. Air compressor packages typically meet API 619, but the customer did not request that in this case. The motors, however, need to meet API 547.

Four Action Items Save Money and Energy at a Refinery

By Hank Van Ormer

This refinery currently spends \$735,757 annually on the electricity required to operate the compressed air system at its plant. The group of projects recommended in the system assessment will reduce these energy costs by an estimated \$364,211 (49% of current use). Estimated costs for completing the recommended projects total \$435,800. This figure represents a simple payback period of 14.4 months. The firm also reduced compressed air demand by 732 scfm allowing them to save \$441,544 by down-sizing the back-up rental diesel air compressors.
