SAJ- Yes, a bit of a brain freeze on my part. I should have said "caustic potash" (KOH) not caustic soda which is NaOH. I will correct it.

High to low, the heat transfer quench list goes something like this:
2.06 - 10% NaOH solution
1.96 - 10% Brine (NaCl) solution
1.38 - 10% KOH solution
1.00 - water @ 65F / 18C
0.40 - very light fuel oil
0.30 - diesel fuel
0.20 - 20wt straight non-det. oil
0.03 - circulated air
0.015 - still air
