Acquiring data for a proper balance is difficult in this situation. The Hx's are in the flow of feed to the multiple evap station and in theory I do think that we will be able to generate enough vapor from each effect. Perhaps I will check out the application and toy around with it a bit...

Hello Gentlemen, I am working on replacing some existing plate and frame HEX with units that can handle more process flow, about 30 percent more. With that, more steam mass flow will be required to give the desired heating. The steam comes from multiple effect evaps. What would be the best way...

"Gbur, calculate the control valve opening for both rated and turndown cases and select the size that is between 10% and 90% open for both cases. Bear in mind that both the flow rate and pressure drop across the valve changes between the rated and turndown case." Do you have a...

Thanks Big Inch... That is the advice I have also received else where.

I need some practical insight here, gentlemen. I have a flow of about 350 cubic meters per hour. This works fine for 10 inch piping (falls well within the range of recommended velocities). What would work better: A) having a 10 inch control valve straight on the line with no reducers? B)...

Thanks everyone - you have all been very helpful :)

Such that an included head loss term in Bernoulli will be able to show me a velocity decrease with the pressure decrease?

Hi All, Lets say you have a pipeline of 100 ft with various fittings, reducers etc, and a velocity of about 5 ft/s entering the pipe line intially. I want to find how much allowable pressure drop there can be so that 5 ft/s does not reach 0 ft/s after its journey through the pipe. Which...

Hi All, I am trying to verify that the external piping arrangment for a plate heat exchanger train (pressure drop on each HEX is 0.2 bar) has been designed for a as-close-to constant velocity. There are currently some elbows, bends, and reducers that add resistance and will of course increase...
