Thanks for the input.
Boiling point elevation occurs as the solution concentrates.
When the solution approaches 30% NaOH, the boiling point rises by 30degrees C requiring an evaporator temperature of 90degrees C.
Delta T is the difference between steam temp and evaporator solution temp.
Or...
It goes on to request evaporator economy
Economy = Vapour product
steam supplied
=0.2934
1
= 0.2934
Again, appears suspect?Other parts require to calculate heat required to raise the feed to boiling temp - I have attempted this...
Below I am unsure of.
Guessing I am wrong though but would require some explanation as to where I am going wrong please:
Calculate
Required Heat Surface Area:
Using Q = U A ΔT
Q = Heat Load
U = Overall heat transfer coefficient 3000W m-2 K-1
A = Heat Transfer Area
ΔT =...
Hi All.
Please can someone help?
I have a question regarding calculating heat load and required surface area for a single effect evaporator.
Details:
Solution Feed rate 1.1kg s-1
Solution feed concentration 8%, concentrated to 30%
Feed solution at 60 degrees Celsius with Specific Heat Capacity...
