Section 8: disposal
regeneration
In practice, the most common regeneration method used is temperature increase. When desorbing water
vapour from silica gel, the temperature shall be above 100°C. A regeneration temperature between
150°C and 175°C is recommended. However, it should be noted that a color indicator applied to the
silica gel will be damaged at these temperatures. Therefore a regeneration temperature of 120°C is
indicated for silica gel with colour indicator and should not exceed 140°C.
