Application

Titanium Oxide Hydrate (TiO(OH)₂) Dryer

Optimization Potential

Titanium Oxide Hydrate is dried before it gets calcined and converted into TiO₂. This patented process helps to increase the capacity of the calciner. After drying the Oxide Hydrate still contained some sulphuric acid which caused corrosion on the process equipment and damage to the filter bags. Filter bags were only lasting 3–6 months. There was also no backup system so dryer and baghouse had to operate 24/7 all year round.

Solution

Enhanced acid resistance GORE™ Aramid Filters were installed and we worked with the customer to optimize the whole system including reducing air flow, installing better temperature control, and providing regular bag analysis to predict remaining baglife.

Results

By replacing generic membrane filters with GORE™ Acid Resistant Filters, and optimizing airflow, life was extended to 9–12 months with continuous system operation.
