First day, morning: 100 points, 70 questions. 40 multiple-choice questions (1 point each) and 30 multiple-select questions (2 points each). First day, afternoon: 100 minutes, 70 questions. 40 multiple-choice questions (1 point each) and 30 multiple-select questions (2 points each). Second day, morning: 50 minutes, 25 questions. Second day afternoon: 50 minutes, 25 questions. 2. The content relates to the principles of chemical engineering; there are few questions involving purely pipeline calculations, with most focusing on pump head, shaft power, and installation height (a question was also asked regarding the head of screw pumps) ； The compressor compresses air, and plate-and-frame filtration is used to determine the filtration time ； Heat transfer is basically present in all cases ； Evaporation was also covered a little, but it can be solved using the law of conservation of mass; it’s recommended to take a look at that. Physical chemistry (mainly reaction heat, enthalpy of formation, Carnot cycle); distillation involves calculation problems related to finding the minimum reflux ratio, the number of theoretical plates, and two-point feeding. Absorption has a math problem. Comparison of several plate towers, calculation of the height of the packing layer. An extraction question was on the exam. There are several questions on drying, such as those related to wet-bulb temperature and the calculation of humidity, etc. There is one step in separation engineering. Reaction engineering has two calculation problems. Residence time of the plug-flow reactor. Several questions were also asked on project management, process design, and engineering economics. It’s best to take a look at them all and underline the various concepts so they’re easy to find during the exam. Materials brought: Principles of Chemical Engineering, Physical Chemistry, Reaction Engineering, Thermodynamics, materials for professional certification exams, and some standards.
