A HAZOP study primarily assesses the following three parts of a plant function: Step #1: Design. To assess the design's capability to fulfill its intended function and identify its weaknesses e.g. the composition of the chemical batch reactor. Step #2: Physical Environment. To assess the environment where the system or design will operate and ...
