Thank you very much for attention to solving my problem.
For your information, I draw the average mass flow rate and temperature per day. Then I use from Q=m*Cp*?T and calculating Qc and Qh and we can calculate fouling factor by this formula: (1- Qc/Qh). (Of course I think).
Now if draw graph...
we can measure the input and output temperatures and mass of cold and hot stream in plate heat exchanger. (Mass of streams isn’t constant therefore we can’t know the losses of heat based on fouling)
I appreciate of allof you that response to my helping ask.
for calculating fouling factor ,i face to actual data in the plant .if i want to make a trend of( T in - T out) * flowrate on either side of the HX ,i have one problem(flow rate is not constant)and trends of Q and U don't go down...
Hi every body
I hope to get my response from your knwoledge.
I want to calculate efficeincy of plate heat exchanger five years after startup.
It's clear efficeincy reduce in during time because U(overall heat transfear cofficient)decrease.
decrease of U due to fouling factor(the amount of...

In Gas sweetening units MDEA(Methyl De-Ethanol Amine, as selective for H2S removal) uses to treat sour gas .
As we know in sweet gas co2 specification is equal 2%mol , in this unit the amount of co2 in sour gas is 1.8%mol that it dose not need to...

Thanks for your following
Briefly design of our plant is based on H2S removal in sweetening unit but now we had to remove CO2 additional H2S. For doing this, the rate of Amin was increased and the Amin’s feed tray was transited to the toppest of the column. I think it is better (if...
hi every body
Please help me in this matter:
I have feed in temperature and pressure in order 24 degree centigrade an 68 barg with 32 component to the Amin-Absorber. for this column ;I want to have equilibrium equation(or curve) , but I don’t know how I can get it.
