What causes scaling on the tube walls during MVR operation, and how to deal with it: handshake
Our company has specialized technologies to prevent structural issues.
It’s scale formed by material crystallization; is there any way to clear the tubes?
Under the treatment with calcium and magnesium ions at the front end, if it’s not due to inorganic salt deposits such as calcium and magnesium ions, then it’s a problem with the system design; the issue lies in the incorrect control of concentration during material crystallization, and it’s necessary to reduce the concentration. If the CP value of the material itself is high, meaning it’s sticky in nature, then it’s necessary to increase the power of the forced circulation pump
Material scaling also forms on the tube walls. What we mainly address are calcium and magnesium-based structures.
From what you’ve described, it seems that the salt in the material has accumulated on the tubes; this issue is likely related to the selection choices made during the initial process design. It is due to an insufficient understanding of the properties of the materials at the initial stage, which leads to problems with the design of the heat exchanger as well as the selection of the circulation pump. This requires you to provide the process parameters so that a re-calculation can be carried out to determine exactly where the problem lies.
