Q: Figure below shows the process flow diagram (PFD) for the hydrodealkylation of toluene (HDA) to produce 500 kmole h of benzene. The main reaction takes place at temperature of 600C with toluene conversion of 80% (ignore the side reactions): C6HCH3 + H + C6H4 +CH ENO tos Carrasco Pedia T-1C1 - 10 C-10A -101 od MOM Hydrogen -161AA 101 6-165 SV Banane 6-192 103 65 1. List all the components that are expected to leave the HDA reactor? and assign destination code to each components? [8 Marks) 2. Vessel V-104 is to be replaced in a plant with a vessel that provides essentially the same process function as the old unit. What should this new vessel be numbered? What each number and letter of equipment C-101A/B means? [10 Marks) 3. Why two different types of heating equipment (E-101 and H-101) were used to heat the same stream? [8 Marks) 4.
