![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 second stage the effluent from Separator 1 is divided into a product stream, containing also the rest of the methane and a waste stream, containing propane (98 wt%)and propylene (2 wt%) that is recycled to the reactor inlet. The requirement for the propylene content of the product stream is for a minimum of 98.8% by weight. (a) Draw the Process Flow Diagram (PFD) of the system and annotate it with the components for each of the streams.

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...

Problem #1: Haber-Bosch process. The Haber-Bosch process is an equilibrium-limited catalyzed reaction that converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3). The process won Haber a Nobel Prize since it provided a way to produce fertilizer for millions of people at the beginning of the 20th century. However, this process typically has very low single pass conversion due to a low equilibrium at the prevailing temperature and therefore a recycle stream is required to achieve a high overall conversion....
