The effluent from a reactor contains a mixture of various chlorinated derivatives of the hydrocarbon \(\mathrm{RH}_{3}\), together with the hydrocarbon itself and \(\mathrm{HCl}\). Based on the following information and the heuristics of Section 9.4, devise the best two feasible separation sequences. Explain your reasoning. Note that \(\mathrm{HCl}\) may be corrosive.
