Selection of condensers
Thread Content
Hello, everyone! I need to design a condenser now, with the following approximate parameters: system vacuum level of 200 Pa, water vapor flow rate of 50 kg/h, fatty acids flow rate of 5 kg/h, air flow rate of 10 kg/h, and inlet temperature of 50°C. How should I calculate the specifications for this condenser? Is it necessary to calculate anything else besides the latent heat of vaporization?
In a condenser operating under high vacuum with non-condensable gases present, it is appropriate to enhance heat transfer; I recommend using software for calculations. Performing manual calculations by determining the freezing point for each component at its corresponding partial pressure and then adding up the loads one by one is too cumbersome. It’s just that the flow rate is too low; I haven’t worked on devices of this size for a long time. Otherwise, I would submit a proposal for an internal finned condenser for you.
Our company specializes in vacuum equipment, and this condenser is also designed to work in conjunction with our equipment.
At 200 Pa, these substances—water vapor and fatty acids—cannot condense! At room temperature, it must be compressed to around 10 kPa in order to condense!
We have done this many times; if you’re interested, add me on QQ at 105786670
