    Sulfuric Acid dilution, H-X material of construction?

    Ametek's heat exchanger looks okay, but we'd prefer an exchanger with higher thermal conductivity, so the size is not too large. Also, we'd like to operate at higher presures, up to 100 psig if possible. Does anyone have experience with a silicon carbide exchanger, info found at...

    Sulfuric Acid dilution, H-X material of construction?

    Tantalum seems very pricey, I don't think that's an option. Anodic protection looks interesting, does anyone have direct experience with how long it lasts in a similar environment? Another option may be Ametek exchangers that have Teflon based tubes. Does anyone have experience with these...

    Sulfuric Acid dilution, H-X material of construction?

    I'm looking for a heat exchanger that can handle 78% sulfuric acid at 320oF. I am diluting 98% acid to 78%, therefore generating a great deal of heat. I've looked into several options inlcuding: Hastelloy B, C and D, teflon/graphite, fluoropolymer, etc. Does anyone have experience with these...

    Waste water treament - besides disposal

    Depending on the type of solvents in the waste water, there are several onsite treatment options that would work (e.g. carbon adsorption, chemical extraction (mpp), steam stripping, etc), since they can handle a wide variety of contaminants. My experience has been that shipping offsite can be...
