PTFE Tank Linings & Equipment
Sulfuric acid is a highly corrosive and equipment design to handle sulfuric must be corrosion resistant. Exotic alloys are available which provide excellent corrosion resistance and long service life. The disadvantages of these alloys are their high costs. PTFE Sheet linings have been used since the early days of sulfuric acid manufacture. They provide excellent resistance to sulfuric acid at a reasonable cost since less expensive materials such as carbon steel can be used for the walls of the vessel or tank.
PTFE-lined Tanks, Vessels, Reactors and Columns
PTFE lined columns and tanks can be employed in various processes, such as:
- Distillation or rectification
- Absorption columns for Hcl/Hbr, etc.
- Liquid extraction
- Storage tanks.
The application range of PTFE-lined columns is from -10°C to +200°C. However, under particularly harsh operating conditions such as those involving high and sudden pressure and temperature changes, or in case of special shapes, etc. these application limits become narrower. Tank lining in PTFE is obtained from virgin materials which are then processed with particular techniques to guarantee high hydrophobicity and dimensional stability. The PTFE linings are available in thicknesses from 3 to 5 mm.
The well-known non-stick properties of PTFE ensure high resistance to fouling and excellent cleanliness, as a result reducing or even eliminating downtimes. Columns and tanks are available in nominal diameters from DN 300 to 2000 in flanged sections up to 2 metres in height (depending on the DN), flat or taper end plates, welded or machined nozzles, along with a range of PTFE internals such as distributors, supports, rings, diffusers, suction tubes, etc.
In case of certified and tested equipment, the use of standard PTFE-lined components allows the repair of the lining without the need for testing the metal substrate again. Tanks and Columns manufactured to customers requirements.
