Goes easy on the flames please,
I operate a textile plant that averages 140,000 gallons of fresh water daily at 115gpm the temp is 80F. The plant loses 11% to evaporation so the waste water averages 125,000 gallons daily at 105gpm the temp is 110F. The plant as plenty of storage capacity for both sources. All the water is softened to 0 grains hardness and all temps are gained from direct contact steam.
Being in california, there is huge potential to save with the rising natural gas prices. This makes it easier to prove return on investment.
My questions are,
A) Where can I find the formula's I'll need to determine sizing, number of passes and flow rates for a heat exchanger that will give the best results.
B) Where can I find the formula's needed to determine the amount of heat transfer that can be recaptured. I ask this second question because I can not exceed 100F with the fresh water. I also need to consider the effects that the higher temp will have on the plant process.
Thanks for you help. Kenny
