MEF 368 Design and operation of chemical aparatus Tutorial 2026

MEF 368: A 6-question pressure vessel design assignment covering ASME Section VIII Division 1 principles, with no institution or course code printed on the source. All 6 questions are fully answered, covering: definitions and classification of pressure vessels; design pressure, design vs. operating temperature, and minimum design metal temperature (MDMT) for a reactor; allowable stress determination and the effect of weld joint efficiency on required thickness and safety; a full numerical shell-thickness design calculation (including thin-wall validity check and corrosion allowance) for a cylindrical pressure vessel; buckling failure and the ASME UG-28 external-pressure design procedure, with a simplified-rule thickness estimate for a vacuum vessel; and nozzle area-replacement reinforcement principles, material selection strategies for corrosive service, and a corrosion allowance calculation.

From this paper

a.
Define a pressure vessel and explain its importance in chemical process industries. b) Classify pressure vessels based on: (i) Pressure levels, (ii) Function in chemical plants. c) Compare cylindrical and spherical vessels in terms of design advantages and applications.
A reactor operates at 12 bar and a maximum fluid temperature of 220 ◦C. a) Determine the design pressure according to ASME guidelines. b) Explain the difference between design temperature and operating temperature. c) Why is the minimum design metal temperature (MDMT) important in pressure vessel design?
