Further downstream, Column 2 separates the lighter boiling impurities—1,2-dichloropropane, epichlorohydrin, 2-methyl-2-pentenal, 1,2,3-trichloropropane—in the overheads and obtains 1-dodecene and DCP at the bottom. Column 2, consisting of 30 equilibrium contacting stages or trays is operated at a design specification of 99.5 percent recovery of the incoming 1-dodecene in the bottoms and 99.5 percent recovery of 1,2,3-trichloropropane in overheads. This requires a reflux ratio (mass) of about 12.1 or a duty of about 9.34×105 J/kg (885 Btu/kg) HCl treated stream. Stream details for Column 2 are shown in Table 9.
