FDC Gas System
Beni presented a preliminary P&I diagram for the FDC/CDC gas systems. Much discussion ensued.
- < 15 psig, non-flammable gases allow us to avoid many ASME issues. Engineers need to sign off anything > 15 psig.
- methane may be used < 5%, non-flammable, pre-mix with another gas the best strategy.
- may need special vents if there's a way for the methane to collect.
- may bubble through alcohol - anti-aging, quencher.
- CDC uses 3 L/min, FDC 1 L/min nominal.
- will use embedded controls, probably will not need any control loops in PLC.
