Steam temperature 110 °C

Seawater intake temperature 35 °C

Terminal Temperature Difference 40 °C

Thermodynamic loss 2 °C

A single stage MSF Distillation Plant has the following data:

Seawater salinity 42,000 ppm

Data same as previous

Overall heat transfer coefficient for brine heater 2.0 KW/m2 °C

Overall heat transfer coefficient for stage condenser 1.6 KW/m2 °C

Calculate the following:

- Logarithmic mean temperature difference of the brine heater =______ °C

Specific area of the brine heater = __________m^2/(kg/s)

- Logarithmic mean temperature difference of the Condenser=________ °C

- Specific Area of the condenser= _________ m^2/(kg/s)

Specific area of the plant= ___________m^2/(kg/s)

A+B \rightarrow R, \text { with }-r_{A}=k C_{A}^{0.800} C_{B}^{0.500} \frac{m o l / b r}{m^{3}}, \text { where } k=12.87 \frac{m^{09}}{m o l^{2} 3 h r}

When the feed rate is 100. m³/hr, you need to obtain 75% conversion of A in afeed stream with CAO = 30.0, CB0 = 30.0 and C10 = 60.0, all in mol/m3.

Complete the table shown below and use the "Simpson's 4 rule" the CHE 443 numerical integrals handout to evaluate the appropriate integral required, then calculate the required volume of a PFR in m³ to obtain the specified conversion for this feed stream.

(Ans: VPFR = 4.16 m³)
