Handling and storage

Reactor/mixer includes mechanical seals and packing to assure good sealing.  

Pumps include mechanical seal to avoid leakage.

Manufacturing process is automated and controlled by a distributed control system (DCS).

Maintenance and plant production staffs are in charge of close system supervision.

The intermediate is pumped trough manufacturing process and to storage tanks using heat-insulated pipes. Storage tanks (one of 90 m3 and another of 55 m3) are heat-insulated too. Used pumps have pressure-relief valves or safety-relief valves. Storage tank venting is driven to an acid gases washing tower. Off-site transport is not intended.

Exposure controls / personal protection

maintenance and cleanning of facilities:

Before maintenance or repair operations, the involved part of the system must be cleaned following the internal procedure (CA-I-58-A). It basically consists in:

-System is loaded with a neutral solvent (mineral oil) containing a 5-10% of concentrated sulphuric acid. Recirculate for 30 minutes.

-System is emptied and the washing mixture is recycled into the production process through a closed pipes system.

-System is loaded and recirculated for one hour with a neutral solvent (mineral oil).

-System is emptied and the washing mixture is recycled into the production process through a closed pipes system.

-If there is any residue, repeat cleaning operation.

-After all residues have been removed, maintenance staff may work using the following appropriate protective equipment:

Respiratory protection: Mask with filter type 92 E1

Eye protection: EN166:2001

Hand protection: PVC gloves (EN 388).

Protective clothing: Category III.

Method and equipment used for sampling the intermediate during manufacturing:

There is an internal procedure (CA-I-59-A) for sampling. Only trained staff with appropriate protective equipment takes samples of the on-site isolated intermediate. After the samples are analysed by the Laboratory, samples are recovered into the production process (emission reduction). Control sampling points and analyses frequency are:

-Storage tank (analytical control 15 times per month)

Personnel exposure:

No exposure, manufacture takes place in a closed system of vessels and pipes.
