WASTE FATTY ACID ADDITION TO BLACK LIQUOR TO DECREASE TALL OIL SOAP SOLUBILITY AND INCREASE SKIMMING EFFICIENCY IN KRAFT MILLS PULPING MOUNTAIN PINE BEETLE INFECTED WOOD
Earlier research at Paprican showed that tall oil production at mills pulping grey stage mountain pine beetle (MPB) attacked wood has dropped substantially due to higher soap solubility in black liquor, a reduced tendency for the soap to "float" off in storage vessels and skimmers, and lower soap quality (acid number). Means to economically increase soap recovery by increasing the fatty acid/resin acid (FA/RA) ratio of the product tall oil were thus investigated. Lab tests showed that the addition of tall oil fatty acids, or waste fatty acids from canola processing, could decrease tall oil soap solubility and potentially increase soap skimming efficiency in the affected mills. Analyses indicated that waste fatty acid addition could be economic at FA/RA ratios of up to 2.5 even when the recovered tall oil is simply burned in the miU's lime kiln, if natural gas and oil prices were high. Full scale mill trials were subsequently run over a 4 day period. The mill trials confirmed that waste fatty acid addition decreased tall oil soap solubility, increased tall oil soap skimming efficiency and produced a higher quality soap that was readily processed in the mill's tall oil plant.
