Action Items from 10/7 meeting

1. Quantify the oil carryover? (Alicia)

  • Data gathering ongoing for C9 and other machines; ~1 order of magnitude difference between oil removed at 4th coalescer between CHL C9 and HDR C1.
  • Does it improve the oil removal to leave the drain valves slightly open?

2. What are the options for the oil sensors and would using a different oil sensor work better? (Nate)

  • ULTRASONIC
  • CAPACITIVE
  • FLOAT SWITCH

Visual indication of whether the automated control is working??

3. Flush the oil. (Mat)

  • On hold until more data can be collected with existing oil.

4. Check the piping for oil after the final oil coalescer with a swab. (Nate)

  • Will be done during shutdown for oil change.

5. Check the orifice size on the compressor. (Alicia)

  • Alicia contacted manufacturer and importer for this information.

6. Pump Oil out of compressors C7 and C8. (Alicia)

  • Withdrawing as much mineral oil as possible: will follow up with Isaac's crew to investigate. On hold until immediately before ready to install. Plan is to do an initial run for some duration, then replace oil (approximates a flush).

7. Add fitting to the tubing from the oil coalescer drain valves back to the compressor body. (Nate)

  • Options exist.
