Acrylate monomers and methacrylate monomers are used to produce many types of chemical products, but are themselves very reactive. Unwanted spontaneous polymerisation can take place with explosive rapidity, and specialised equipment is needed to prevent an auto-reaction occurring during storage or transport. The RESTAB system provides additional protection.
Increased safety with RESTAB
Based on a BASF patent, RESTAB restabilises acrylates which have already started to self-polymerise in a storage container. It complements, but does not replace, conventional safety measures.
RESTAB mixes the tank contents with an inhibitor when a reaction threatens to start or has already begun.
The RESTAB liquid is highly effective, and only 50 kg is needed to stablise a 100 m3 tank. This enables it to be filled into small mobile containers which can be used and adapted as required depending on the individual process.
Components of a RESTAB system
A RESTAB system consists of:
RESTAB is a trademark of BASF, registered in Germany and other countries
The telescopic lance is fixedly secured to a flange of the tank cap. In normal operation, the retracted telescopic elements are in the gas space of the tank.
Operation of RESTAB
The user connects an RS dry-disconnect coupling from the mobile tank hose to a fireproof pipe, and opens the nitrogen valve. The following sequence of events then takes place automatically:
