TOPIC 3 Flashcards
when fluids are used to make solids flow the solids later must be
recovered
why was the separation method created
are designed to take advantage of the unique properties of the substance that have been mixed.
what is the desert tent method (much like distillation)
is inexpensive, but slow, and only practical in areas which receive a lot of bright sunlight
what are desalination plants
they are along the Red Sea use a lot of energy and are very expensive to operate.
what is the process called dehydration
the process of removing water from a solution.
during dehydration what happens
the solvent which is water in most cases is separated from the solution by means of evaporation
what is distillation
is a separation method that allows all the liquid fractions of a mixture to be separated from each other
this is an example of
distillation
this is an example of
desert tent mehod
what is petroleum
is a natural mixture of hydrocarbons
what is fractional distillation
the process that yields different petroleum products
when petroleum is heated
it changes into a gas ( petroleum)
when petroluem is collected and cooled it….
it changes back to a liquid (recodense)
what happenes to the recondesed liquid
is further seperated ( the parts recondense at different temperatures) into each of fractional parts that are soluble in eachother but not water.
fractional distillation is done in
two- toner structure and the fractional products can then be converted into different types of petrochemicals.
