(40 pts; 2 pages) Energy balance without reaction. Researchers at Michigan State University have developed a sustainable process for converting biomass to sugars that can then be converted to fuels

and chemicals. This process involves using liquid ammonia (NH3)at high temperatures and pressures to pretreat the biomass. Consider the recycling process for the spent ammonia at the pilot scale. Spent ammonia vapor at 130°C and 40 bar is condensed and compressed back to liquid at 120°C and 100 bar. The condenser removes 1.45 kW of heat from the inlet ammonia stream. Determine the work in hp required by the compressor. The heat capacity of ammonia in liquid phase is 0.0808 kJ/mol/°C and assume that heat capacity is independent with temperature. The specific gravity of liquid ammonia is0.604. a. (20 pts) Determine the unknown specific enthalpies H1 and A2 in units of kJ/kg. To help your calculations, please use the inlet-outlet enthalpy table below and explicitly state your reference states! (20 pts) Set up and simplify the appropriate form of the energy balance equation. Use this to solve for the work added to the system by the compressor in units of hp.
