6. Distillation: Why do we need reflux to return back to
distillation columns? How the reflux ratio will affect the design
and operations of distillation process.
Is there a minimum reflux ratio for the batch distillation? If
so, how can we determine it experimentally? Please help me with
this. I'm not sure since batch operates like one stage but the
slope of the rectifying section is the same? Is it the same way as
finding Rmin for Continuous distillation? Thanks!
Define reflux ratio and explain its importance in distillation
process. (4)
4.2. Explain how the reflux ratio affects number of stages in
the distillation column. (4)
4.3. State six conditions of the nature of feed for fixed reflux
ratio. (6)
4.4. List six scenarios when liquid-liquid extraction is
preferred over distillation. (6)
Why do we need to maintain liquid level in the bottom of
distillation column? (also liquid level in accumulator)? Is there
relation between maintaining liquid level in the bottom of
distillation column with operability of kettle reboiler?
6) What is biodiversity? What are the components of
biodiversity? Why do we need to preserve biodiversity (give three
reasons and argument your choices)?
1. Define Current Yield and Yield to
Maturity. Why do we need two return measures on bonds?
2. Describe the assumptions we need to make for the
constant-growth dividend discount model.
3. Why risk can be measured by variance/standard deviation?
4. Briefly describe the CAPM model. Why stock/portfolio's
expected returns are associated with market risk premium?
