Multiple-choice question: Cold reflux involves cooling the top product to a ( ) state before sending it back to the top of the tower, in order to control the temperature at the top of the tower, provide reflux within the tower, and ensure product quality. 1. Saturated liquid 2. Subcooled liquid. Correct answer: 2. +2 points for correct answer +5 points for in-depth discussion @Guan Gongyu
Cold reflux involves cooling the top product to state (2) and sending it back to the top of the tower, in order to control the temperature at the tower top, provide reflux within the tower, and ensure product quality. 1. Saturated liquid 2. Subcooled liquid
Cold reflux involves cooling the top product to state (1) and sending it back to the top of the tower, in order to control the temperature at the tower top, provide reflux within the tower, and ensure product quality. 1. Saturated liquid 2. Subcooled liquid
Cold reflux involves cooling the top product to state (2) and sending it back to the top of the tower, in order to control the temperature at the tower top, provide reflux within the tower, and ensure product quality. 1. Saturated liquid 2. Subcooled liquid
Cold reflux involves cooling the overhead product to state (2) and returning it to the top of the tower, in order to control the tower’s overhead temperature, provide reflux within the tower, and ensure product quality. 1. Saturated liquid 2. Subcooled liquid
2. Supercooled liquid. Cold reflux, strictly speaking, refers to reflux whose temperature is lower than the equilibrium temperature of the tray into which it is fed, such as top reflux and recycle reflux. However, the term \"cold reflux\" commonly used refers to the subcooled reflux at the top of the tower; that is, the product from the top of the tower is taken out, condensed and cooled outside the tower, and then fed back to the top of the tower as reflux for the uppermost tray.
Cold reflux involves cooling the top product to a (2) supercooled liquid state and returning it to the top of the tower, in order to control the temperature at the tower top, provide reflux within the tower, and ensure product quality.
