fractional distillation Flashcards
1
Q
fractional distillation
A
a separation technique to separate crude oil using fractions
2
Q
process
A
crude oil is heated at 400 degrees and passed through a fractional column
vapour from the column rises then condenses when cool enough
then the hydrocarbons will be split into fractions based on there boiling point
3
Q
fraction
A
groups of hydrocarbons of similar chain length
4
Q
properties
A
top of column
low bp
low viscosity
low molecules
bottom of column
high bp
high viscosity
low molecules
5
Q
crude oil
A
mixture of hydrocarbons and dead remains of animals
