parameter a=5

For a future distillation process - which is currently in the design phase - there are five fluid streams. The mass flow rates, specific heat capacities and target and supply temperatures for each stream are shown in Table Q3. Table Q3: Stream data (a) What is Pinch technology and explain why it is utilised in chemical and process industries? (b) Calculate the external heating and cooling requirements if there is no heat recovery between the streams? (c) If the minimum allowable temperature difference between the streams is (20+a)C, where parameter a represents the last digit of your student registration number. For example, if your student number ends in a '6' the minimum allowable temperature different between the streams would be 26C. Use the problem table method to determine the extemal heating & cooling duties and the Pinch temperatures. For each step write a short description to explain the methodology
