ESBR techniques

The techniques listed are rated according to the scheme shown in Table 12.9. 

Storage Minimise level variation (integrated plants only) L M 

Process equipment Collect the vents for offsite treatment H H 

Diffuse (fugitive) Monitoring of flanges, pumps, seals, etc. H M 

The feedstock is, in general, supplied by pipeline from nearby production facilities or marine terminals. In some plants monomers are delivered by road or rail tankers. The plant storage tanks must be designed and maintained to prevent leaks and resulting soil and water pollution.

ESBR and SSBR are made from two different addition polymerisation techniques one radical and one ionic. ESBR polymerisation is based on free radicals that attack the unsaturation of the monomers, causing addition of monomer units to the end of the polymer chain, whereas the basis for SSBR is by use of ionic initiators (qv).
