Thread Content
64. Under which operating conditions is it appropriate to equip the distillation column top condenser with a fractionator? A. Multi-component condensation, with the final condensation temperature being higher than the bubble point of the mixed components. B. Multi-component condensation involving inert gases. C. Multi-component condensation, with the final condensation temperature being equal to or lower than the bubble point of the mixed components. D. Condensation of multi-component gases with a high dust content. How should this question be approached, and where can relevant information be found? I couldn’t find any relevant information in either the \"Chemical Process Design Manual\" or the \"Petroleum and Chemical Engineering Design Manual\"
The Chemical Process Design Handbook contains the exact wording on heat exchangers in one section.
AB has no doubts. C is incorrect. D shows no relevant content
Answers: AB. Classification and selection of heat exchangers in the Fourth Edition of the Chemical Process Design Handbook, page 598
A. Multi-component condensation, with the final condensation temperature being higher than the bubble point of the mixed components. B. Multi-component condensation involving inert gases
