A chemical industry in Muscat producing a product B as per the following homogenous gas phase second orders reaction, A----3R. The feed is entering at a rate of 4 m3/h of pure A at 623 K and 5 atm The experimental reactor having a size of 25 mm internal diameter and 2m length given 60% conversion of A

A commercial plant is to handle 320 m3/h of feed containing 60% A and 40 mole% inerts at 350 C and 25 atm for obtaining 80% conversion of A

(Assume: Plug flow reactor and ideal gas behavior)

(i) Calculate the volume of reactor for both experimental and commercial reactor

(ii) Calculate the no. of lengths of 25 mm ID x 2 m length pipe that are needed for 80% conversion

(iii) Calculate the number of pipe [Similar to specification of Q(iii)] by graphical method for commercial plant(attach the graph sheet)

(iv) Should they (pipe length) be arranged in parallel or in series? Give reason
