- In A Tubular Reactor The Dehydrogenation Of Ethane To Yield Ethylene As The Desired Product R1 Takes Place Simultaneo 1 (51.67 KiB) Viewed 49 times
In a tubular reactor, the dehydrogenation of ethane to yield ethylene as the desired product (R1) takes place simultaneously to other two side-reactions (R2 and R3), resulting in methane and propylene as sub-products, C2H6(g)→C2H4(g)+H2(g)C2H6(g)+H2(g)→2CH4(g)C2H4(g)+C2H6(g)→C3H6(g)+CH4(g) R1 R2 R3 The process is designed to produce n˙C2H4( g), out =15kmol⋅hr−1 of ethylene, with a fractional yield of YC2H4(g)=0.4. The selectivity of methane respect to hydrogen production is fixed to Calculate: (i) Fractional conversion of ethane, αC2H6(g). [25 marks] (ii) Molar composition of the outlet stream leaving the reactor. [5 marks] (iii) Considering that the inlet and outlet streams are at 25∘C and 1 atm, estimate the heat rate released or consumed in the reactor. [10 marks] NOTE. Consider εA=0 for all the compounds.
