A.H. Lundberg-Turpentine recovery

Crude Sulphate Turpentine (CST) recovered from the kraft pulping process is typically used as a fuel or sold as a by-product. CST dumped to sewer in large quantities can upset the effluent treatment system (it is toxic to the bugs in high concentrations).

CST is toxic and extremely flammable so caution must be used when handling it.

Pulp mill foul condensates containing high levels of CST should be recovered and treated in the turpentine recovery system.

A.H. Lundberg-Soap Layer Detection

In kraft softwood mills, tall oil soap is a valuable by-product as well as a toxin in the wastewater treatment system. Thus it is necessary to properly manage foam and soap within the mill.

Managing this issue requires a number of steps including the handling and deaeration of foam, separation of soap from liquor, and the separation of liquor from soap. Once the soap is separated from the system, it should be kept separate and not remixed with the liquor.

New technologies emerging from the by-product recovery of black liquor soap include conversion of the soap to bio-diesel fuel (SDRF process) and the extraction of other valuable by products such as sterols.
