Background
Titanium dioxide is mainly produced via two processes: the sulfuric acid method and the chloride method. The production involves harsh working conditions with high temperature and high pressure throughout the process. Pipes and valves suffer severe wear as they constantly contact acid-base corrosive media and slurry containing solid particles.
Production lines are required to operate continuously. Conventional valves are prone to leakage, poor wear resistance, low regulation accuracy, short service life and low automation, which easily lead to production malfunctions, product quality fluctuations and high operation and maintenance costs. GRAT electric hard-seated ball valves feature excellent temperature and pressure resistance, superior wear resistance, zero leakage and intelligent regulation. They are perfectly tailored for the complex working conditions of titanium dioxide production, ensuring stable and efficient operation of production lines.
Key challenge
- Poor sealing performance: Acid, alkali and particle-laden slurry tend to leak, resulting in raw material waste, equipment corrosion, potential safety hazards and unplanned downtime.
- Insufficient flow regulation accuracy: Fails to meet process requirements of each working procedure and causes unstable reaction parameters, which directly affects the quality and yield of finished titanium dioxide products.
- Low automation: Relies heavily on manual operation without remote intelligent control, leading to low production efficiency and high labor costs.
- Bulky and redundant valve structure: Restricts installation in complex pipeline layouts, and increases difficulties and costs of installation, operation and maintenance.
