Setting up flash vessels, 3-phase separators, and complex distillation, absorption, or stripping columns. 5. Logical and Advanced Tools aspen hysys user certification exam questions

: A Explanation : A Mixer requires zero additional inputs if the inlet streams are fully defined. HYSYS automatically calculates the material and energy balances to determine the outlet stream's temperature, pressure, flow rate, and composition. Question 3: Column Specifications Logical and Advanced Tools : A Explanation :

You have added a centrifugal pump to your flowsheet. You specified the inlet stream, the outlet stream pressure, and the pump efficiency. However, the pump block remains yellow and reads "Not Converged." What is the most likely missing input?A) Fluid Package definitionB) An attached Energy StreamC) Ambient temperatureD) Pump curve data You specified the inlet stream, the outlet stream

C (or specifically the Amine/Glycol enhanced packages). Standard Peng-Robinson often fails to model the polar interactions of water and glycol correctly.

You are modeling a crude distillation unit. You have an assay with TBP data from ASTM D86. In the Aspen HYSYS Petroleum Assay Manager, which step must you perform before you can send the crude to a distillation column?
