Task :You were asked to evaluate the following process used to produceacetylene from methane. The following reactions takes place during theprocess:CH O CO H HO xOCH CHH xCHCHC H xCHCO HO CO H xCOThe feed flow of methane is given per group in kgmoleh pure andoxygen enough is used to have full conversion of oxygen and enough heatto trigger the desired pyrolysis of methane to produce acetylene.Calculate the molar composition of the products leaving the reactor by handusing material balance.Calculate the amount of carbon dioxide and hydrogen generated during theprocess. Support your calculations by the given data and balanced reaction.Determine the selectivity of acetylene over the side products.Calculate the extent of the reactionUsing HYSYS design the process considering the following aspects: The fluid package is Extended NRTL The acetylene production is achieved by pyrolysis of methane with aconstant feed of methane and oxygen at oC and constantpressure bar. The reaction is trigger by the heat generated by the exothermiccombustion reaction at constant pressure.Find the molar composition of the stream leaving the reactor for givenconditions.Compare selectivity and extend of the reaction obtained by HYSYS with theone previously calculated.Determine the amount of heat and energy that can be obtained from thereaction.Evaluate the effect of the feed temperature on the yield of acetylene.Design the optimal conditions and further unit operations required to obtainpure acetylene the required product to sell clean water and hydrogen.Use stream envelope analysis to adjust conditions of pressure andtemperature for unit operations.Save your HYSYS file as the main process.Make a process flow diagram including all required unit operations,streams, conditions, and hand calculations.Compare hand calculations with results obtained with HYSYSConsider recycling any unreacted components on the product compositionusing HYSYSSave your HYSYS file as recycled process.Note:It is important to check that the recycle feed is adjusted to the fresh feedconditions before mixed so that the conditions of the reaction are notconstantly modified. In the HYSYS model a recycle logic operation isrequired, you may need to purge solid carbon.
