I usually seen fan or compressor curves in Nm3/hr. But if its actual, usually its the suction flow.

Hi, I'm not an expert in filter vessel with polymer powder but I can suggest just getting from brochure from vendor that is nearest to your application. Then add a generous amount of margin. You may contact vendors directly for more precise pressure drop vs flow curve. SAMPLE...

Refer to AGA Purging Principles and Practices

I supposed that the vent of this "atmospheric equipment" be routed to a safe location. Normal purging of 200 kg/hr would be detrimental indoor. As georgeverghese mentioned, please make sure to do a backpressure backwards calculation with CV failure flowrate. Do not account for the closing of...

1 horsepower = 0.746 kilowatt (NOT kilowatt-hour)

I agree that there is no code that dictates piping be protected against fire. But on my experience, to be conservative on relief load, pipings are accounted to the PSV on the upstream drum of the pump.

Hi, I just want to ask if there is a chance to have a pressurized gas exiting drain lines of gas turbines? I'm suspecting turbine casing and the enclosure skid drains. Christopher Kenneth Choa

Just want to ask typically how much coupling hubs a compressor have? A typical gas turbine rated about 20+MW. Nany Thanks. Christopher Kenneth Choa

I would like to ask where to find molecular weights and latent heat of vaporization of complex lube oils (Shell Tellus ISO 360 and Aeroshell ISO 560). I would also like to ask if one can simulate them in HYSYS/UNISIM? Christopher Kenneth Choa

What if I don't do not have the lighter fluid (oil) during start up... Will I have inaccurate reading? Christopher Kenneth Choa

I think radar is possible alternative, but I really do want to stick with dP (cheaper). Christopher Kenneth Choa

@danw2: How will the transmitter know the percentages? I know that it only measure pressure difference, how come it can know the percentage? Is the formula like this? dP = x1*rho1*g*h1 + (1-x1)*rho2*g*h2 where x1 and x2 are mass fraction. However, there is 2 unknowns... x1 and h1... And...

Can DP transmitter read interface level? Christopher Kenneth Choa

HI, I done simulation with ELECTROLYTE NRTL, with the electrolytes like H+, OH- and others defined as composition. I am just wondering why in my simulation run, none of them have values on the composition workbook. Are they just intermittent species which HYSYS consider them non existing when...

Thanks TD2K, I think I will add several reactions in the package environment first. Christopher Kenneth Choa

Thanks MortenA for the reply. But I do want to clarify things. The reaction is a reversible reaction by double displacement only. Should I still have a reactor even if I'm building a plant without reactor? Many Thanks for the reply. Christopher Kenneth Choa

Its from a compressor system. So from a burner. Christopher Kenneth Choa

Hi, I'm definitely new to HYSYS and other process simulation tools. I just have a question in HYSYS.. If I do want a sour water stripper with a caustic injection on it (this will entails having an equilibriun reaction between the NaOh and other components inside the stripper), should I still...

Thank poli60. :) Christopher Kenneth Choa

I know its a Shell license design, however, is there any meaning or logic why its ADIP? Thanks! Christopher Kenneth Choa
