Advanced Separation Processes n-decane is to be recovered from nonvolatile oils

Advanced Separation Processes

n-decane is to be recovered from nonvolatile oils in a steady-state single-stage steam distillation. The feed is at a rate of 10kmol/h and contains 50mol%n-decane. A residue stream containing 17mol%n-decane in the organic phase is required. Assume feed enters at the temperature of the unit, and that the system operates at 1 atm. Assume also that the molar latent heats are equal. Find: Page 2 of 7 (i) the temperature of the still (ii) the feed rate of saturated steam to the unit. Data: lnPvep(mmHg)=AT(K)+CBforwaterA=18.3036B=3816.44C=46.1forn-decaneA=16.0114B=3456.80C=78.67
