  1. Part 5 Nasser Faleh Al-Ajmi 205114238 Cooler E-107 distillation column

  2. Heat exchanger • Sample calculation • Specification sheet

  3. Sample calculation • Calculating the heating load  Qh = mh *Cp * (T1-T2)hot • Calculate cooling flow rate  Fcooling = Q / (cp*ΔT) cold • Temperature correction Factor calculation:- assume two tubes and for shells and calculate R , S and ∆Tlm R = (T1-T2) / (t2-t1) and S = (t2-t1) / (T1-t1)  Ft ∆Tlm =(T1-t2)-(T2-t1) / ln((T1-t2)/(T2-t1))  ∆Tm = Ft * ∆Tlm • Calculating Provisional area A=Q/U*∆Tm ((U is assumed)) • Calculating the no. of tubes Nt= (provisional area/area of one tube) • Calculating the shell diameter Ds=Db+Bundle diametrical clearance Db=Db = (do)*( Nt / K1)^ (1/n1)  ((k1 and n1 are constants))

  4. Total flow area = tubes per pass * cross sectional area • mass velocity = mass flow rate / total flow area • linear velosity (ut ) = mass velosity / density • Calculate inside coefficient for water hi = (4200* (1.35+0.02t)* ut0.8)/(di0.2) ((di tube inside diameter))
