Step 1 of modification to the CS instrument air supply
Today, I performed the 1st stage of modification to the instrument air supply setup for the Corner Station which, when completed, will reduce the compressor's runtime (duty-cycle) by ~65%. Step 1 - added double check-valves to the output of the drying towers. Also, added isolation valves and Tees w/swagelok ports between the reciever tank and the pressure switches (both LEAD and LAG).
This is an improvement in reducing energy and increasing equipment life. Additionally, we plan to replace this reciprocating piston style compressor unit with a scroll style similar to original.
