SOLVE PROBLEM 2

Problem 1 . A 500 gpm pump is used to provide water to a reactor vessel (MAWP = 100 psig). If the pump continues to operate, the reactor might be overfilled and overpressurized. Determine the relief area (in2) required to protect the vessel. Based on the GPSA list of relief valves (in notes), what size of valve body and orifice designation do you recommend? Clearly state all assumptions.

Problem 2. In part (i) of Homework #8, we estimated that the mass flow rate during the loss of cooling water relief scenario would be approximately 34,000 lbm/hr. In part (ii) of the homework, we determined that relief valve would open very quickly after the loss of cooling water. If we assume that the composition of the vapor flowing through the relief valve is most similar to the distillate product, what is the required orifice area of a conventional relief valve? You may assume that the relief is sent to a flare that is near atmospheric pressure. Clearly state all assumptions.
