Consider the following flash drum system shown in FIGURE Q1. The purpose of the V-40 flash drum is to separate multiple mixture of mostly A and B plus some other heavy components to produce main products leaving the top at 90 mol% of A. Steam at 5 bar is used to bring the temperature at the desired saturation temperature. As a process safety engineer, you a required to perform a HAZOP study on the V-40 by focusing on the process parameters of LEVEL and PRESSURE, using the guide words of LESSand MORE. Suggest all possible causes, consequences and actions for each guide word.
