Chapter 11 (Hazard Identification) question \#11-3 OTE that chapter 11 of the book hard copy may appear as chapter 10 in the online pdf irsion. The question is about HAZOP analysis on an heat exchanger as discussed. Question 11-3: A heat exchanger is used to heat flammable, volatile solvents, as shown in Figure 10-15. (Fig 11-5 hard copy).The temperature of the outlet stream is measured by a thermocouple, and a controller valve manipulates the amount of steam to the heat exchanger to achieve the desired set point temperature. a. Identify the study nodes of the process. b. Perform a HAZOP study on the intention "hot solvent from heat exchanger." Recommend possible modifications to improve the safety of the process
