He catalytic dehydrogenation of propane is carried out in a continuous packed-bed reactor. one thousand kilograms per hour of pure propane is preheated to a temperature of 670 °c before it passes into the reactor. the reactor effluent gas, which includes propane, propylene, methane and hydrogen, is cooled from 800 °c to 110 °c and fed to an absorption tower, where the propane and propylene are dissolved in oil. the oil then goes to a stripping tower in which it is heated, releasing the dissolved gases; these gases are recompressed and sent to a distillation tower in which the propane and propylene are separated. the propane stream is recycled back to join the feed to the reactor preheater. the product stream from the distillation column contains 98% propylene and recycle stream is 97% propane. the stripped oil is recycled to the absorption tower. questions: 1. state the number of units involve in the catalytic dehydrogenation process of propane. 2. ascribe names to each unit identified 3. generate a block flow diagram for the process and give a detail labelling of the bfd based on the information given in the problem statement. 4. develop a process flow diagram (pfd) for the process 5. performed an overall material balance 6. state the degree of freedom based on the overall material balance

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
