LATIHAN 8.5-4. Concentration of NaOH Solution in Triple-Effect Evaporator. A forced-circulation triple-effect evaporator using forward feed is to be used to concentrate a 10 wt % NaOH solution entering at 37.8°C to 50%. The steam used enters at 58.6 kPa gage. The absolute pressure in the vapor space of the third effect is 6.76 kPa. The feed rate is 13 608 kg/h. The heat-transfer coefficients are U₁ = 6246, U2 = 3407, and U3 = 2271 W/m² K. All effects have the same area. Calculate the surface area and steam consumption. 8.5-1. Boiling Points in a Triple-Effect Evaporator. A solution with a negligible boiling- point rise is being evaporated in a triple-effect evaporator using saturated steam at 121.1°C (394.3 K). The pressure in the vapor of the last effect is 25.6 kPa abs. The heat-transfer coefficients are U₁ = 2840, U₂ = 1988, and U₁ = 1420 W/m² K and the areas are equal. Estimate the boiling point in each of the evaporators.

The power generation unit in a plant uses a hot exhaust gas from another process to produce work. The gas enters at 10 bar and 350°C and exits at 1 bar and 40°C. The process produces a net amount of work equal to 4500 J/mol and it exchanges an unknown amount of heat with the surroundings. 1.1 Determine the amount of heat exchanged with the surroundings. Is this heat absorbed or rejected by the system? 1.2 Calculate the entropy change of the exhaust gas. 1.3 As a young and ambitious chemical engineer, you seek ways to improve the process. What is the maximum amount of work that you could extract from this system? Assume that the inlet and outlet conditions of the exhaust gas remain the same. Additional data: Assume the surroundings to be at the constant temperature of 298 K and the exhaust gas to be ideal with CP = 29.3 J/mol.K
