Material of acid vapor stripping heat exchanger
Thread Content
Dear friends, what materials are used for the acid water stripping heat exchangers in coal chemical industries, and how is their performance? Has anyone used dual-pass silicon carbide heat exchangers? Graphite heat exchanger? Manufacturing plant?
Operating conditions: type of medium, temperature, pressure, corrosive nature of the medium, etc.? Is it a reboiler, heat exchanger, or cooler? Petrochemical enterprises mostly use carbon steel
A graphite heat exchanger is used at this operating condition.
How is the performance of the graphite heat exchanger? What is the manufacturer?
120℃, 0.2 MPAG, vapor stripper cooler at the top of the tower
Made of carbon steel; the tube bundle only needs to be coated for corrosion protection.

If the tube bundle is to be coated, what medium should be used? How is it performing? Who is the manufacturer? Can it be inspected? Or communicate with relevant technical personnel
In the coal chemical industry, are there any applications for top coolers in acid water stripping towers? How is it performing?
