Only applicable to plants using raw materials with a high olefin content
b.
Clay material selection
Use a clay that lasts as long as possible for its given conditions (i.e. having surface/structural properties that increase the operating cycle length), or use a synthetic material that has the same function as the clay but that can be regenerated
Generally applicable
