Electrochemical Scale Inhibitors

Electrochemical scale inhibitors utilize an electric field or current to alter the crystallization process of minerals. This prevents minerals from forming hard, strongly adherent scale on pipe surfaces, instead causing them to form softer, less adherent crystals. This non-chemical or low-chemical method uses a special alloy to create a galvanic cell, which increases the water solubility of the material, transforming scale into a spherical form, and even promoting the gradual dissolution of existing scale. This equipment is used in a wide range of industries, including oil and gas, power plants, and manufacturing, offering a maintenance-free and environmentally friendly alternative to traditional chemical corrosion inhibitors.

Working Principle

1. Galvanic Cell: The device uses special alloy electrodes to create a galvanic cell, which generates an electric current.

2. Crystallization Alteration: The electrochemical process increases the solubility of mineral ions, such as calcium carbonate, while also altering the activity of their solvents and solutes.

3. Morphological Change: Instead of crystallizing into dense, irregular scale, the mineral forms soft, spherical, and less adherent particles, which are easily washed away by water. 4. Ablation: Through electrochemical action, existing scale and rust on the pipe surface are gradually softened and removed.

Key Features and Benefits

1. Non-Chemical/Low-Chemical: Eliminates or significantly reduces reliance on chemical inhibitors.

2. Environmentally Friendly: An environmentally friendly solution that avoids the generation of hazardous chemical waste.

3. Reduced Maintenance: Provides long-term stable operation with low maintenance costs, typically with a service life exceeding five years.

4. Wide Application: Effective in high and low temperature environments across various industries.

5. Equipment Protection: Prevents equipment corrosion by maintaining surface cleanliness and inhibiting deposit formation.

Applications

1. Oil and Gas Industry: Prevents scaling issues in pipelines and downhole operations, including inhibiting the accumulation of asphaltene and wax.

2. Industrial Water Systems: Treats water in heat exchangers, pipes, and vessels.

3. Power Generation: Used in thermal power plants to maintain power generation efficiency and prevent scale formation. 4. Manufacturing: Applied in cement production, paper mills, pharmaceutical manufacturing and other fields.
