What are the factors to be considered for Solvent Selection ?
The factors to be considered are: 1. The gas solubility should be high, thus increasing the rate of absorption and decreasing the quantity of solvent required. 2. The solvent should have a low vapour pressure to reduce loss of solvent in the gas leaving an absorption column. 3. The materials of construction required for the equipment should not be unusual or expensive. 4. The solvent should be inexpensive, so that losses are not costly, and should be readily available. 5. Low viscosity is preferred for reasons of rapid absorption rates, improved flooding characteristics in packed column, low pressure drops on pumping, and good heat transfer characteristics. 6. The solvent should be non-toxic, non-flammable and chemically stable.
How to Calculate Operating Line Slope for Absorption Column?
Operating Line Slope for Absorption Column calculator uses Operating Line Slope of Absorption Column = (Solute Free Mole Fraction of Gas in Inlet-Solute Free Mole Fraction of Gas in Outlet)/(Solute Free Mole Fraction of Liquid in Outlet-Solute Free Mole Fraction of Liquid in Inlet) to calculate the Operating Line Slope of Absorption Column, The Operating Line Slope for Absorption Column formula is defined as the slope for operating line of absorption column plotted on solute free basis mole fraction. Operating Line Slope of Absorption Column is denoted by LGratio symbol.
