Meeting 8/15/2017

Attenders: Kelly Dixon, Shirley Yang, Nusair Hasan, Corey Butler, Nate Laverdure

• 1. Kelly announced that Dick Brown would join the team soon to help with the new 2K cold box concept design.
• 2. The draft P&I ws reviewed and the following issues were discussed:

      * I)LN2 is going to be used as the thermal shield. The return is going to be back to the 4K cold box same as the existing system. 
      * II) The 3 ATM He supply to the individual cold compressors will be removed per Nusair's suggestion.
      * III)Kelly suggested using smaller line and valve to get rid of the orifice on teh pipe from CC5 discharge to the He recovery system. 
      * IV) The primary relief valve will be installed on teh discharge of the CC5 cold compressor as the existing 2K cold box system. Kelly suggested Nusair to compare the relief system design on the existing 
        2K cold box to the design on the SCN 2K cold box.
      * Nusair will evaluate the bypass control valve on the CC3 once he gets the detailed cold compressors information.    

• 3. Nusair worked out the specification of the 2K-4K heat exchange.
• 4. Nusair is working on the P&I update of the CHL cooling water system.
