Celanese Acetate manufacture cigarette filters which are made from acetate flake and this involves using both rotary washers and rotary driers in the manufacturing process.  However, as this process also involves the use of a lot of acid they are always in need of repair.  The equipment is generally hard to work on as they are usually in hard to reach places, inside a building making access extremely difficult.

We recommend that regular surveys are carried out on these items of equipment to highlight any work that needs doing to prevent breakdown of equipment and subsequently loss of production time and loss of income.
