Question 8 [10%] A simulation of the process for the manufacture of ethylchloride as shown in the figure below. The process involves a recycle flow, and it is noted that the recycle block has not converged. What is the reason? a. The maximum number of iterations needs to be increased. b. The operating pressure has to be changed. c. The value of Q Minimum needs to be reduced d. The operating temperature has to be changed. e. The flowrate of stream W has to be changed.
