- Distillation column design. - Storage tanks design. - Air cooler design.

Introduction : Distillation column is used to separate components according to their boiling point temperature. Objective : To produce high purity of ethyl benzene and distillate product.

Assumptions: For c Sieve plate. - Material of the distillation is carbon steel - Column Efficiency =77.7%. - Tray spacing = Flooding Percentage=85%. - Down Comer Area=12%. - Hole area( 0.1 of Active area). - Weir height ( 50mm). - Hole diameter (5mm). - Plate Thickness (5mm). - Turn down Percentage (70%)

- Specify the properties of outlets streams for both vapor and liquid from HYSYS. - Calculating actual no. of stages: - Actual Number of stage = Nm/ efficiency Where, Nm : no of theoretical stages Efficiency = 77.7%

- Column diameter:

- Liquid flow pattern:

- Provisional plate design: Where lw, the weir length

- Checking Weeping: Where; h ow is the weir crest liquid in (mm). u h is the liquid velocity in (m/s). u vapor is the vapor velocity in (m/s)

- Residence time: - Entrainment:

- Number of holes: where, Ah: the total area of the holes Dh: the hole diameter

- Thickness calculation: where, - D is the column diameter in m - rj is internal radius in (in). - P is the operating pressure in psi - S 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).

- Cost estimation: where, H: column height V: volume of the column M: mass of the column

Introduction : Tanks are basically was made to hold, transport or store fluid and solid.

 Volume of the liquid= Total mass flow rate in* time hold-up  Time hold-up: the time where the liquid is hold inside the tank  Volume of cylinder = π R 2 H … (1)  Get the volume of the liquid (assume H=0.2D)  To determine vapor pressure Antoine equation is used:  Log 10 P* = A- (B/C+T) … (2)  T: the temperature in ˚C  The values of A, B, and C is taken from table Antoine equation constant  At this vapor pressure the top space in the tank can be determined.  the total volume=volume of liquid/0.12 … (3)  Diameter 3 = (5*total volume)/ П  Height = 0.2diameter  Area of the tank = total volume/ height … (4)  Thickness  t = (P r i / S E - 0.6P) + Cc …(5)

What is air cooler? Air coolers are devices to reject heat from a process fluid directly to ambient air.

1-calculate the heat duty : Q= m Cp Δ T Where, Q: heat duty m: mass flow rate Cp: heat capacity Δ T : Temperature difference

2- CALCULATE OVERALL HEAT TRANSFER COEFFICIENT 3-CALCULATE MEAN TEMPERATURE DIFFERENCE

4-Calculate correction on mean temperature difference 5- Calculate Area Δ Tm=lMTD*Ft Q=UA Δ Tm A=Q/(U Δ Tm)

7- # tube Nt=A/A assume 8-Calculate horse power requirement HP=mcp Δ T* Cost (from matche.com)
