Material Balance without Chemical Reaction
Process:
Batch Process (Unsteady State)
Continuous Process (Steady State)
Input + Generation - Output - Consumption = Accumulation
At steady state condition, Accumulation = 0.
No chemical Reaction: Input=Output.
Some Unit Operations:
Drying
Evaporation
Distillation
Crystallization
Leaching
Extraction
Mixing
Absorption
Absorption
Solute gas in the inlet gas = Solute gas in lean gas + SXolute gas in Solvent
Inert gas in gas mixture entering the absorber = Inert gas leaving the absorber (inert gas in the lean gas)
Recovery or removal of a solute gas component from a mixture with another component gas (inert gas) with the help of a suitable solvent in which the solute gas is absorbed
Crystallization
Magma- is a mixture of Crystals and mother liquor.
4.Solubility: (weight of solute)/(weight of solvent)
Mother Liquor: the remaining part of solution separated from the Crystals
5.Weight fraction: (weight of solute)/(weight of solvent+weight of solute)
1.Super Saturated: Solvent contains more solute than it can ordinarily be accommodated at that temperature.
6.Crystal: weight % of solute = (molecular weight of solute)*100/(molecular weight of crystal of solute)
%Yield = Amount of solute in the Crystal/Amount of
solute in the feed(C
xC
100)/(F*xF)
Distillation:
High Volatility means high vapor pressure and low boiling points
2.Distillation column--Rectification and Stripping section
D/F = (xF-xW)/(xD-xW)
W/F = (xF-xD)/(xW-xD)
Reflux or Recycle Ratio = L/D
% Recovery = (Solute in Distillate)*100/(Solute in Feed)
%Loss = (solute in Waste)*100/(solute in Feed)
Drying is removal of relatively small amount of water from solids
Evaporation includes the removal of large amount of water from
solutions
Degree of Freedom:
No of Degree of Freedom (Nd) = No of Unknown variable (Nu) - No of Independent terms (Ne)
Nu = Ne (exact solution exists)
Nu>-Ne >0 (Underspecified)(more independent eq required)
Nu<-Ne <0 (Overspecified)(no sol exists)
