The characterisation of organic components in the calcium and magnesium effluent streams at Sappi Saiccor

Sappi Saiccor is one of the few pulp mills that use the acid sulphite pulping process with hardwood feedstock to produce a high-grade cellulose pulp. The major constituents identified in the calcium effluent stream and the magnesium condensate effluent stream were a mixture of lignan isomers, episyr...

More Information
Summary:Sappi Saiccor is one of the few pulp mills that use the acid sulphite pulping process with hardwood feedstock to produce a high-grade cellulose pulp. The major constituents identified in the calcium effluent stream and the magnesium condensate effluent stream were a mixture of lignan isomers, episyringaresinol and meso-syringaresinol and lignin-type precursors such as 3-(4'-hydroxy-3', 5'-dimethoxyphenyl)-prop-1-ene, 2, 6-dimethoxy-1, 4-benzoquinone, 3-(4-'hydroxy-3', 5'-dimethoxyphenyl)- 1-hydroxy-propane-2-one, syringaldehyde and vanillin.
