Reflux condenser
Reflux condenser
Introduction
A reflux condenser, also called a vent condenser or knockback condenser, is a vertical tube-side condenser in which the vapor flows upward. These units are typically used when relatively small amounts of light components are to be separated from a vapor mixture. The heavier components condense and flow downward along the tube walls, while the light components remain in the vapor phase and exit through the vent in the upper header.
Model: Vertical or horizontal;
Heat transfer area: 0.1- 1000 m2;
Tube: φ8, φ10, φ12, φ14, φ16, φ19, φ25, etc;
Material：CS, SS304, SS316, 2205, Tiatanium, Hastelloy C276, ;
Features
In distillation applications they are most often used as internal condensers, where the condensate drains back into the top of the distillation column to supply the reflux, or as secondary condensers attached to accumulators . These units have excellent venting characteristics, but the vapor velocity must be kept low to prevent excessive entrainment of condensate and the possibility of flooding. The fluid placement (coolant in shell) entails the same disadvantages as the tube-side downflow condenser.
- Usually used for reflux condensing.
- Low cost because of simple structure
- Easy cleanning by removing the head, but not for the dirty fluid
