Evaluation of Two Chemical Treatments in Outside Chip Piles.
Abstract
Three experimental chip piles, two of treated chips and one of untreated, were built at a pulpmill woodyard in South Carolina. The chips for one of the two treated piles were immersed in mill green liquor; those for the other, in a 0.25 percent solution of sodium N-methyldithiocarbamate. The sodium N-methyldithiocarbamate treatment suppressed the initial heating for about 1 month, and significantly reduced losses of tall oil and turpentine in the samples removed after 2 months. Both treatments reduced losses in wood substance by 1% (absolute) after 2 months, but neither had a significant effect after 6 months. Six-month storage in the untreated pile had little effect on the overall yeild or on the strength of kraft pulp from the chips.
