Quality issues of desalinated water
Thread Content
In refineries, does the desalinated water used in equipment, pipelines, and pumps cause scaling inside those devices? :lol:lol
It depends on the quality of your water; generally, scaling is unlikely in desalinated water, as the levels of calcium and magnesium ions that can cause scaling are very low in it.
Desalinated water and deionized water are used to reduce and prevent scaling inside the tube bundles and tube walls; once salts such as calcium and magnesium are present in the water, scaling occurs very easily in areas with high temperatures and low flow rates.
You also said it’s demineralized water; water without salts doesn’t tend to form scale, only corrosion occurs, and that corrosion is quite severe, so it needs to be taken seriously.
Desalinated water is not the same as “distilled water”; acid washing can be used in some cases to address the issue.
Meets the standards for boiler water and does not cause scaling
In a situation like yours, chemicals are generally added
It is best to consider anti-corrosion measures for the inner walls of all equipment and pipelines, without the need to add any chemicals.
