The raw material used in the production the new Covid 19 drug presented in question 1 is made in a plant where a counter -current heat exchanger is used to cool a gaseous process stream. The stream (20 kg/s) enters at 431 K, has a heat capacity of 3.45 J/g°C, and needs to be cooled to 402 K. Cooling water is available at 302K and has a specified maximum temperature of 322K. The overall heat-transfer coefficient is approximately 570 W/m²K. You are assigned to design that heat exchanger. How much area must the heat exchanger have?

3 As an engineer in a production facility, your assignment is to specify the size of a CSTR reactor needed to produce the new Covid-19 drug (C19P). The secret ingredient A as liquid stream (concentration=0.85 M) enters the reactor at 20 Litre per second, where it is consumed by irreversible reaction and too form C19P in the presence of a catalyst, called C19-enzyme. The equation of the reaction is: A + C19-enzyme – C19P Treaction A = KpCa=0.020C, a) What is the difference between a plug-flow reactor and a continuously stirred tank reactor? Please provide detailed, fully labelled diagrams to support your answer b) What is the role of a catalyst for any reaction? Please provide detailed, fully labelled diagrams to support your answer c) What reactor volume is needed so that the concentration of species A leaving the reactor equals 0.05 M? The density can be assumed to be constant. 4 The raw material used in the production the new Covid 19 drug presented in question 1 is made in a plant where a counter -current heat exchanger is used to cool a gaseous process stream. The stream (20 kg/s) enters at 431 K, has a heat capacity of 3.45 Jlg°C, and needs to be cooled to 402 K. Cooling water is available at 302K and has a specified maximum temperature of 322K. The overall heat-transfer coefficient is approximately 570 W/m²K. You are assigned to design that heat exchanger. How much area must the heat exchanger have?
