Guys, Do you know what is the max temperature that these wheel can handle? And can it utilize a hot plant exhaust stream on the regenerator side?

Steam moles ----------------- > 4 Carbon moles Steam = H20 moler flow Carbon = any hydrocarbon beside CO2 eg; if you have 3mol/hr of C2H6 = C moles = 3*2=6 mol/hr and you need to sum all the hydrocarbon to have the Total C mol/hr

You can't use those numbers without knowing the dT Check this old post: http://www.eng-tips.com/viewthread.cfm?qid=276525&page=7

overdesign! A1 = A*(1+x) x=20% , A1=1.2A

Why Burning when you can make electricity - google Fuel Cell Energy

Hi Mike, I bumped into your question during my forum search, and it sounds familiar :-) I found a nice paper (student thesis) that summaries Liquid/Liquid cyclone separation (hydrocarbon and Oil in particular)...

Well, you need something to balance you pH back - can you run your RO plant without acid? Or adding small amount of Alkalis to get pH > 6?

Sounds like you create a slug flow - I would move the mixing point before the valve (reduce the amount of flashing) but if you can't do that (pressure issues) I had a good experience with spraying cold fluid in a 2 phase separator vessel (similar to direct condensing) Tell me if you need a draft.

you can protect the SS with corrosion inhibitor (water additive) like film forming amines

Temp? water composition (TDS, Ion-)? pH?

Helium (don’t have to be pure) and a group test

Spectacle blind AKA figure-8 blank AKA Madka AKA scissor blind - Use the same pipe and valve flanges -so your "skilled" engineer won’t open the solvent line on the maintenance guys. -add a line in your check list to check them before starting up.

Hey All, Can a fuelcell work at 100% fuel utilization (Uf)without damaging to the cell? What will happen if we extract more power? Thanks J

Check with your electrical/PLC engineer and see if he has a spare AO (analog output). A control valve will give you more options. - How many times you need to drain the tank?

120% of the Total flow or one spare (if you have 5 PSV each will be 24% of the max flow) One with a lower set-point is a nice trick to overcome small bumps, but you need to make sure that your vent line stay atmospheric (otherwise you will cause back pressure on the others)
