Thank you for the CEMA references. They will do nicely.

Can anyone point me to a source for bulk densities of solids like limestone, pebble lime, fly ash, sodium bicarbonate, and soda ash? The best method, of course, is to test the actual material to be stored, but this is often impossible at the quotation stage. I am looking for reasonable values...

I've got a problem with a cooling tower. The cooling tower is cooling service water that is basically city water with the normal, small concentrations of biocide and dispersants which are added and monitored by the water chemical company. The tower is performing well thermally, but has failed...

Thank You!

The application is to drive a high-pressure atomizer array. The service is continuous. You can assume the water is river water that has been passed through a sand-filter to remove the leaves, crawdads and silt. There may be a few granules of sand and an occasional fleck of scale from the...

Can anyone recommend pump type/manufacturer for the following application? Service water at 90 deg F, 100 gpm to be delivered at 1500 psig (3500 ft tdh). Thanks! ppeng01

Thank you for your help!

I must not be making myself clear. If I have a condenser that feeds into a reflux accumulator drum (that is vented), is it realistic to expect that I can get away with one outlet in the condenser that will convey both the condensed liquid and noncondensible vapor through the outlet piping into...

The partial condenser is going to be on an amine regenerator unit. The vapor coming off the regenerator will be water and carbon dioxide. The condensed liquid and vapor will pass from the condenser to a reflux accumulator drum. Most of the water will be condensed and will be used as reflux...

I have a question about a partial condenser. When I am condensing a liquid out of a gas mixture, I always thought there needed to be a gas outlet at the top of the partial condenser and a separate flowpath for the non-condensibles to prevent accumulation and vapor binding of the condenser. I...

Thanks!

Thank you! The 33,000 is the conversion from ft-lbf/min to Horsepower and the equation I posted is for acfm. I am talking about 7.5 million pounds per hour of gas or 2.5 billion scf/day. Thank you for the reference to axial compressors. I knew I would have to use multiple compressors, if it...

Am I slipping a decimal point somewhere? 2E6 acfm * 60 min/hr * 24 hr/day * 88% = 2.5e9 scf/day = 2500 mscf/day Theoretical Hp if one stage is approximately 144/33,000*(1.4/(1.4-1))(14.7 psia)*(2e6 acfm)*((115/15)^((1.4-1)/1.4) - 1) = 354,500 Hp It looks like...

I may not have been clear about the flowrate. The flowrate should be 2,000,000 acfm @ 14.7 psia, 130 deg F, and at a density of 0.06 lbs/ft^3. This is just a thought problem, but I am curious about the feasibility of compressing fluegas from a power boiler from 15 psia to 100 psig.

What is the largest practical limit for a compressor? Is it feasible to compress a gas stream as large as 2e6 acfm to 100 psig?
