'Cox' chart which is useful in the design of a distillation column (particularly suitable for petroleum hydrocarbons) is a plot of the_____________?
Correct answer: A. Temperature vs. log (vapor pressure)
- A. Temperature vs. log (vapor pressure)
- B. Vapor pressure vs. log (temperature)
- C. Log (temperature) vs. log (vapor pressure)
Explanation
A Cox chart linearizes vapour-pressure data by plotting temperature against the logarithm of vapour pressure, which is especially useful for petroleum fractions. Hence the plotted variables are temperature and log(vapour pressure).
