One method of producing propylene is the dehydrogenation of propane (C3Hs) to propylene (CsHs) according to the reaction: A schematic of the reaction is shown below. The fresh feed (Stream 1) has a total flow rate of 100. mol/min and is composed of 96 mol% propane and 4.0 mol% propylene. The single pass conversion of propane across the reactor is 40% and all of the hydrogen is separated in the flash drum. Stream 5 exiting the flash drum is...

Propane is catalytically dehydrogenated to produce propylene by passing it over a granuar solid catalyst. In parallel with the main gas-phase reaction of propane dehydrogenation, side reaction to methane and carbon occurs: C,H,C,H +H A single-pass conversion of propane of 80%Is achieved in the reactor. Out of the propane reacting, 20% reacts according to the side reaction. The reactor effluent gases undergo a two-stage separation. In the first stage all hydrogen and 90% of the methane is separated, in the...

Part 1:Propane dehydrogenation (PDH) is the extensive pathway to produce propylene, which is one of the most important petrochemical building blocks for the production of a diverse range of products, from solvents to plastics and other valuable intermediates. The other by product of this reaction is hydrogen gas. The reaction is happening at atmospheric pressure. Here is the balanced equation of the reaction: (7 marks) C3H8(e) C3H6(g) + H2(8) 1. How much propane in grams...

5) The most conventional method for producing propylene oxide is by the reaction of propylene with Hz and O2. However, propane is also produced from a competing reaction of propylene with Hz. If you mix a stream contains propylene, hydrogen and air (6, 18.6 and 27 mol/h, respectively) with an inert carbon dioxide (3000 mol/h) stream and fed them to a continuous reactor. The reactor effluents introduced to a condenser where the condensate liquids consisting propylene oxide, propylene and propane...

6.1. Propylene oxide (C,H,O is produced by reacting propylene (C,H) with oxygen and hydrogen. A side reaction resulted in reacting propylene with hydrogen and produces propane. A mixture of 35 mol/h Air, 4 mol/h propylene, and 12.6 mol/h hydrogen (H2) along with 5000 mol/h carbon dioxide (CO, is used as inert solvent) are fed to a continuous reactor. The percent single-pass conversion of limiting reactant is 10%. The fractional yield of C3Hs to C,H,O is 0.80 (i.e., fraction of moles...
