Should I choose a graphite heat exchanger or a polypropylene heat exchanger?
Thread Content
We have an acidic fluid with a temperature of around 50°C; it mainly consists of dilute sulfuric acid and sulfurous acid. The flow rate is approximately 25 m3/h. 316L stainless steel is not resistant to corrosion, so we are considering using graphite coolers or heat exchangers made of reinforced polypropylene and graphite. Could you help analyze which option is more suitable, taking into account the costs associated with using each type of cooler as well as their reliability? Thank you!
A graphite cooler is a good choice – a cylindrical porous graphite cooler. Send me the data and I’ll help you with the design. cyh980037@163.com
Those upstairs should explain the reasons and criteria for the choice, as well as provide a comparison of advantages and disadvantages, so that more people can learn*learn*, hehe~
If I had to choose, I would go for the block-hole graphite condenser, as it is more durable than reinforced PP graphite tubes. In our branch factory, there was a 20-square-meter reinforced PP graphite tube condenser that broke down after less than 2 years of use.
It’s better to consult a factory that produces graphite heat exchangers for this purpose; there are many such factories available online, and their choices are quite professional
