Problem $1$

Liquid fuel type$-$A is produced from pure micron$-$size plastics via pyrolysis at high temperatures $($e$.$g$.850C).$ During the pyrolysis, $80\%$ is converted into the desired product A and other byproducts $(B$ and $C)$ while $20\%$ remains unconverted. The feed is a mixture of plastic bags with other wastes while the product must be pure$-$A stored at room temperature.
