The BCTMP process, particularly in evaporation plants, faces challenges from inorganic deposits or scaling. Scaling occurs when minerals like calcium sulfate (CaSO₄), barium sulfate (BaSO₄), calcium carbonate (CaCO₃), and silica (SiO₂) solidify on equipment surfaces. These deposits often form in high-temperature, high-pressure areas where dissolved solids concentrate, making evaporation plants especially vulnerable.
Scaling and fouling significantly impact efficiency. Thick scale layers reduce heat transfer in evaporators, increasing energy use. Frequent cleaning is required, leading to higher chemical consumption and downtime. Over time, scaling can cause equipment wear, unplanned stoppages, and production losses, driving up costs and reducing plant efficiency.
Banmark offers innovative solutions to control inorganic deposits, keeping evaporation plants clean and efficient. Using advanced chemical technologies and process expertise, we tackle scaling challenges to ensure productivity and cost-efficiency for BCTMP mills.
Properties and Benefits
Banmark’s inorganic deposit control solutions are designed to target the root causes of scaling and fouling, offering state-of-the-art technologies that mitigate deposit formation. These solutions utilize:
- Crystal modification technology to alter crystal structure, preventing the formation of hard and adherent deposits on equipment surfaces.
- Threshold inhibition techniques that disrupt the growth of crystalline deposits even at low concentrations.
- Dispersing agents to keep particles suspended in the liquid phase, reducing the likelihood of solid deposit formation.
- Process stability under extreme operational conditions, including high temperatures and pH variations, ensuring reliable performance in challenging BCTMP environments.
The use of Banmark’s deposit control solutions brings tangible benefits to evaporation plants and other BCTMP operations:
- Maintains evaporator efficiency by minimizing scaling and associated heat transfer losses.
- Reduces the frequency and duration of acid cleaning, allowing for longer uninterrupted production runs.
- Extends the lifespan of equipment by preventing scale-induced damage and wear.
- Cuts down on energy consumption by preserving optimal heat transfer rates.
- Enhances the overall efficiency of chemical recovery systems, contributing to operational sustainability.
These benefits demonstrate how proactive deposit control translates into measurable cost savings and continuous process improvements.
Usage and Applications
Banmark’s inorganic deposit control solutions are versatile and specifically tailored for use in critical areas of the BCTMP process, including:
- Evaporation plants, where scaling risks are amplified due to elevated concentrations of dissolved solids.
- Heat exchangers and concentrators, where mineral deposits compromise thermal efficiency.
- Process water systems, which are vulnerable to scaling induced by calcium, barium, and silica.
- Black liquor circuits, where the quality of liquor affects overall performance and recovery operations.
Optimal results require proper application. Banmark offers clear dosing recommendations to boost chemical efficiency, along with system monitoring to adjust treatments as conditions change. Our solutions are also designed to work seamlessly with other process chemicals, ensuring stability across systems.
