Heat Exchanger Design Cooler E-100 Heater E-108

Assumptions Shell and tube heat exchanger counter flow is used because it is more efficient than the parallel flow. The value of the overall heat transfer coefficient was assumed based on the fluid assigned in both sides. outer, the inner diameter and the length of the tube were assumed.

Heat Exchanger Design Heat Load Where, Cp: Avg. specific heat of the fluid (cold or hot ). ΔT: Temperature difference . M : mass flow of the fluid

Heat Exchanger Design Log Mean Temperature difference Where; T1 is temperature of inlet hot stream. (C) T2 is the temperature of outlet hot stream.(C) t1 is the temperature of inlet cold stream. (C) t2 is the temperature of outlet cold stream.(C).

Heat Exchanger Design Correction factor: for more than one tube passes correction factor is used

No. Of Tubes Calculations Where; L is the length of tube (m). do is the outer diameter of tube (mm). di is the inner diameter of tube (mm). ut is the velocity of flow rate (m/s).

Thinkness Calculations where D is the shell diameter in m rj is internal radius in (in). P is the operating pressure in psi is the working stress (psi). E is the joint efficiency Cc is the allowance for corrosion (in). T is thickness of the column in (in).

Reactor Design Reaction type -> transkylation Reaction. The Reaction is to produce ethylbenzene from the recycled PEB and Benzene.
