Question is ⇒ Flash distillation is, Options are ⇒ (A) same as differential distillation., (B) used for multicomponent systems like crude refining., (C) same as simple distillation., (D) most useful for handling binary systems., (E), Leave your comments or Download question paper. See below example: This is one of the most common examples of industries using flashing systems. The left image is about Ethylene Dichloride and the right side video is Methanol production from Syngas. Methane and Ethane will be recovered later on, while the stream must be further treated. Binary ash In a binary ash there are two components, 1 and 2. Multicomponent Flash Distillation 34 Example 2-2. Simultaneous Multicomponent Convergence Example 2-3. It is a shortcut multicomponent distillation rating model used to separate an inlet stream into two product streams. When a multicomponent liquid stream undergoes a sudden decrease in pressure (by, for example, flowing through a valve), part of the feed vaporizes. Have you ever wonder how useful is Flash Distillation? May be you think it is a very simple process that is not actually used in the industry, or maybe you think it is just a simple unit operation… well, let me tell you it is not! 2.6 Multicomponent Flash Distillation.
