CHBE 241 Material and Energy Balances Department of Chemical and Biological Engineering The University of British Columbia Problem Session #1 Tuesday, 12 September 2006, CHBE 101, 2–4pm 1. Balanced Chemical Reaction Equation: Ammonia Synthesis . Ammonia synthesis proceeds by reacting methane (CH 4 ) with steam (H 2 O) to make CO and H 2 . Then CO and H 2 O react to form CO 2 and more H 2 . Finally, N 2 and H 2 combine to produce NH 3 . Write the three balanced reactions for this process. 2. Generation-Consumption Analysis: The LeBlanc Process . In this process, salt (NaCl) and sulfuric acid (H 2 SO 4 ) are heated in batches to produce sodium sulfate (Na 2 SO 4 ) and hydrochloric acid (HCl). The balanced chemical reaction is 2NaCl + H 2 SO 4 Na 2 SO 4 + 2HCl (1) The sodium sulfate is then cooked in furnaces with coal (C) and limestone (CaCO 3 ) to produce a “black ash”. Sodium carbonate (Na 2 CO 3 ) is washed out of the black ash with water, leaving behind calcium sulfide (CaS). These reactions are
