A hot benzene vapor stream at 500oC and 1 bar is rapidly cooled by mixing with liquid benzene at 25oC and 1 bar. The stream leaving the mixer must be 200oC and 1 bar. Assume the reactor is at constant volume. Determine the flow rate (in mol/hr) of the liquid benzene feed stream assuming the flow rate of the hot benzene vapor stream is fixed at a certain value x (specified in the quiz question). Use the polynomial approximations for heat capacity and Table B.20 when appropriate. Assume the flow rate of the hot benzene vapor stream is fixed at 1,253 mol/hr and the liquid benzene feed stream is your reference state. What flow rate (mol/hr) of the liquid benzene feed stream must be used? Round your answer to the nearest tenth and do not include units. Use Tables B.17 and B.20 to tabulate relevant data.  Remember that temperatures for polynomial heat capacities are in Kelvin.

3. A device is being designed to separate a natural gas having a molar analysis of 94% CH4 and 6% C2H6 into components. The device will receive natural gas at 208C, 1 atm with a volumetric flow rate of 100 m3/s. Separate streams of CH4 and C2H6 will exit, each at 208C, 1 atm. The device will operate isothermally at 208C. Ignoring kinetic and potential energy effects and assuming ideal gas behavior, determine the minimum theoretical work input required at steady state, in kW.

Methane is burned with air in a continuous combustion reactor that is at steady state.The feed to the reactor contains 7.80 mole % CH4, 19.4 mole % O2, and 72.8 mole % N4. The percentage conversion of methane is 90.0%, and the gas leaving the reactor contains 8 mol CO2/mol CO. Carry out a degree of freedom analysis of the process, and calculate the molar composition of the product stream.

Stoichiometry is a significant part of chemical engineering. In industrial practice, stoichiometry followed by material and energy balances (MEB) is particularly important for each unit process/operation. This task focuses on the understanding of a chemical operation and its input-output stream characteristics involving MEB adapted in the entire process. select any sub process from a major unit and complete the following tasks                                                                                                                              Process Flow Diagram and stoichiometry Provide the complete Process Flow Diagram (PFD) and explain the concept of stoichiometry including the calculations involved in the process

To produce superheated steam at 300 oC and 1 bar in the output stream (stream 3), saturated steam at 1 bar discharged from a turbine at a rate of 1150 kg/hr to stream 1 is mixed with superheated steam available from another stream (stream 2) at 400 oC and 1 bar. The mixing unit operates adiabatically. Calculate the amount of superheated steam at 300 oC produced in kg/hr and the required volumetric flow rate of the 400 oC steam in m3/hr. the value of H1 is 2,675 kj/mol. find the value of h2 and h3. Calculate the amount of produced superheated steam at 300 oC in kg/hr. Calculate the required volumetric flow rate of the 400 oC steam in m3/hr.
