UPDA Chemical case studies
UPDA Chemical · Put your knowledge to work in context.
The UPDA Chemical Engineering Examination is a professional certification assessment for chemical engineers, intended to demonstrate that a candidate can apply core chemical engineering principles to practical process problems. It suits engineers preparing for or advancing into responsible process roles, and those who want an independent, exam-based validation of their technical breadth. The exam is multiple choice and is organised around ten domains: fundamentals and applied mathematics, material and energy balances, thermodynamics and phase equilibria, fluid mechanics, heat transfer, mass transfer and separations, reaction engineering and reactor design, process control and instrumentation, process design and economics, and health, safety, environment and ethics. Expect calculation-heavy items alongside conceptual and code-of-ethics questions; most numerical problems are solvable in a few minutes with the right equation, so familiarity with units and standard correlations matters more than deep derivation. The UPDA Chemical case studies are 5 cases and about 5,706 words.
1Reactor Temperature Runaway
A jacketed batch reactor is used to perform a first-order exothermic reaction A → B. The reactor is charged with 2000 kg of reaction mixture (density 1000 kg/m³, specific heat capacity 4.0 kJ/(kg·K)).
