1 You are involved in a project to purify a 30% methanol-water mixture from another process. Before distilling the mixture, it has been proposed that the mixture should be preheated to 80 C. An existing 1 shell- 1 tube pass AEL shell and tube heat exchanger is available. Data available: Tube side: Shell side: 41.67 kg/s of methanol-water mixture Inlet temperature = 25 C 3.81 kg/s of saturated steam at 4 bar to
