Describe three different separation processes and identify the physical/chemical/biological principle on which the separation is based.

Expert Solution

Chromatography:

Chromatography is a separation technique used to separate the different components in a liquid mixture. It was introduced by a Russian Scientist Michael Tswett. Chromatography involves the sample being dissolved in a particular solvent called mobile phase. The mobile phase may be a gas or liquid. The mobile phase is then passed through another phase called stationary phase. The stationary phase may be a solid packed in a glass plate or a piece of chromatography paper.

The various components of the mixture travel at different speeds, causing them to separate.

Distillation

It based on the principal seperatins the components of mixture containing two miscible liquid that boil without decompsition and have sufficient difference in boiling point.

Extraction

is a separation process which separating substance from matrix. The mixture is brought into contact with the

a solvent in which substance of interest is soluble but other substance is insoluble.

. Draw a block flow diagram for a petroleum refinery that includes three different separation processes, five different conversion processes along with one or more finishing processes, and one supporting process to produce altogether nine commercial fuels and materials from a sour crude oil. Clearly label all the feedstocks, processes, and products on your diagram including the type of process (separation, conversion, finishing, and support) and the intermediate products. Make sure that all processes are correctly connected. Write down the...

Discussion Question : Describe one physical, chemical, biological or psycho-social stress hazard that workers can be exposed to on the job, and one strategy that can be implemented to prevent or reduce the exposure. Why is it important for primary healthcare providers, (physicians, nurse practitioners, and physician assistants) to ask patients about their occupation when performing routine physical exams?
