Autoclave and Flash Vessel Lining

For about 50 years the mining industry has been using the technology of liquid phase oxidation as a treatment to remove sulphur from ores in a so called highpressure-acid-leaching (HPAL) circuit. Acid resistant brick-linings are state of the art for anti corrosion linings in these HPAL tanks like autoclaves, flash, heater and quench vessels.

The design of brick linings has to take into account the almost non-elastic behaviour of the brick lining inside a relatively highly elastic steel vessel. STEULER-KCH has got tools and data available to determine the thermal growth and pressure expansion for steel vessels as well as the linear thermal expansion and chemical swell for brick linings. Thermal shocks and pressure drops are not regular operating events but their negative influence on the lifetime of a brick lining has to be a part of the engineering study. Finite Element (FE) models as well as a lot of research and development on brick lining materials is the only way to find a path through the complex engineering work for pressure vessels (temp. 150 -220 °C, 5- 28 bars).

STEULER-KCH offers:

  • Sealing layers, cements based on synthetic resin and waterglass
  • Shaped bricks and special formats in various material grades
  • Finite element analysis and engineering for stress-analysis, temperature profiles and displacements of lining
