Can you please help me with this : For the HDA Process

1. Calculate the amount of heat required in E-101 to preheat thefeed stream mixture (Stream B) from your previously calculated temperature (say, -46C)

to 225C. Here you need to determine the boiling point temperatures ofthe individual vaporizing components (i.e. toluene and benzene), their corrected latent heatsof vaporization (AHY) while being heated in E-101. Remember that the heat

For the HDA Process 1. Calculate the amount of heat required in E-101 to preheat the feed stream mixture (Stream B) from your previously calculated temperature (say, -46C) to 225C. Here you need to determine the boiling point temperatures of the individual vaporizing components (i.e. toluene and benzene), their corrected latent heats of vaporization (AHY) while being heated in E-101. Remember that the heat load consists of 8 individual terms (3 for benzene, 3 for toluene, 1 for H2 and 1 for CH4). You need to list all eight Q's calculated. 2. Find the heat load of the fired heater (H-101) to preheat feed Stream 4 from 225C to 600C (Stream 6). 3. Find the bubble point temperature of the feed entering the distillation column (i.e. Stream 10). 4. Find the bubble point temperature at the bottom of the distillation column (i.e. Stream 11). 5. Find the dew point temperature at the top stream of the distillation column (i.e. Stream 13).
