Equipment Design Presented by Hanadi Al-Sendi Supervised by: Prof. M. Fahim Eng. Yousef Ismail
introduction • there are three main types of reactors which are: CSTR Batch FBR
Fixed bed ReactorCRV – (100 – 103) • Objective : Styrene Production • C6H5C2H5 + CO2 → C6H5C2H3 + CO2 + CO • Design Procedure: • State all the assumption for all reactors:
Apply Plug flow design equation: Eq.1 • Define A rate law: Eq.2 - Combining Eq’s 1&2 Eq.3
- Calculate the volume of the reactor: Where; ρb: isthe catalyst bulk density. W: is the weight of catalyst. Φ: is the bed porosity. - Calculate the reactor length.
- Calculate the thickness: Where; t: thickness of reactor. P: internal pressure = 14.696Psia r: radius of the vessel = 1.75m = 5.74147 ft. E: joint efficiency = 0.85 S: stress of carbon steal = 13700Psia. Co: corrosion allowance = 0.125in. - Calculate the cost.
CRV - 104 Oxidation reactor Objective : convert CO to CO2 Design procedure: The same procedure used in the first four reactors. • State all the assumption for all reactors:
- Apply a plug flow design equation: Eq.4 - Define a rate law: Eq.5 • Combining Eq’s 4&5 : Eq.6
CRV – 104 ( results) ε = -0.019057 x = 1 W = 40,000 kg L = 11.0134 m t = 0.5385 cm Cost $ = 148,600 $
