Questions 1.What is a distillation column ? 2.What is separator? 3.What is evaporator? 4.What is Aspen HYSYS? 5.What is volatility? 6.What is simulator? 7.What is process modeling? Answers: 1.A distillation column is an essential item used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities 2.A machine or device that separates something into its constituent or distinct elements. 3.An evaporator is a device in a process used to turn the liquid form of a chemical substance such as water into its gaseous-form/vapor 4.Aspen HYSYS is a chemical process simulator used to mathematically model chemical processes, from unit operations to full chemical plants and refineries. 5.Tendency of a substance to evaporate at normal temperatures 6.a program enabling a computer to execute programs written for a different operating system. 7.Chemical process modeling is a computer modeling technique used in chemical engineering process design. It typically involves using purpose-built software to define a system of interconnected components, which are then solved so that the steady-state or dynamic behavior of the system can be predicted
