The Principles and Practice of Engineering (PE) Chemical Engineering Exam is the definitive credential for professional chemical engineers in the United States, signifying the highest standard of competency and ethical practice. Administered by the National Council of Examiners for Engineering and Surveying (NCEES), this rigorous examination is the final step toward licensure as a Professional Engineer (PE). Earning the PE license grants the legal authority to sign and seal engineering drawings, submit plans to public authorities, and take responsibility for chemical engineering projects. It validates an engineer's ability to protect public health, safety, and welfare through advanced knowledge in areas such as process design, thermodynamics, reaction kinetics, and plant operations. This certification is not merely a test of academic knowledge but a comprehensive assessment of practical, experience-based judgment essential for independent practice. It is widely recognized by employers, government agencies, and clients as the benchmark for technical proficiency and professional reliability in the chemical process industries.

A fired heater burns 100 kmol/h of propane completely with 20% excess dry air. Dry air is 21 mol% O2 and 79 mol% N2, and water is condensed before dry gas analysis. What dry-basis O2 mole percent is expected?
A liquid feed contains 60 wt% solvent. A bypass sends 25% of the feed around a membrane; the treated branch leaves at 90 wt% solvent. Neglect losses. What solvent concentration is in the recombined product?
At a solvent recovery unit, a preliminary cost estimate for a heat exchanger is $250,000 at 500 ft^2. A similar exchanger is needed at 800 ft^2. Using a 0.6 capacity exponent, what purchased cost is estimated?
A slurry transfer line carries 0.040 m^3/s. To limit erosion, design velocity should not exceed 2 m/s. What inside diameter is the smallest reasonable starting point before allowances?
At a resin unit, an air-to-open valve supplies cooling water to a jacket on an exothermic batch reactor. Loss of instrument air is credible. What fail action is normally preferred?
