Water is used to extract sugar from 50 tonnes/h of sugar beets.
The beets have the following composition by mass: 48 wt% water, 40
wt% pulp, and 12 wt% sugar. The sugar syrup leaving the extractor
contains 5 wt% sugar and no pulp. Forty-five per cent of the sugar
in the original sliced beets is recovered in the syrup. The
residual beet stream leaving the extractor contains 3 tonnes of
sugar syrup (sugar + water) per each tonne of pulp.
a) Draw a flowchart of the extraction process.
b) Calculate the flow rate of each stream in tonnes per hour.
