Yueyang Paper's high recovery rate of alkali recovery in 2002

In 2002, Yueyang Paper Industry Co., Ltd. made a number of technological transformations to the chemical pulping and alkali recovery production line, and achieved gratifying results. The alkali recovery amount reached 20,598 tons, the alkali recovery rate reached 76.14%, and the alkali recovery rate and alkali recovery rate were both. A record high.

In 2002, Yue Paper completed a number of major technological transformations and technological research topics such as chemical pulping, causticizing of wood pulp with alkali, high-performance long-grid washing presses, electrostatic dust removal, and refinement of white mud refining calcium carbonate process technology. The successful implementation of the project has further optimized the equipment and processes of the entire pulping and alkaline recovery production line, ensuring the continuous and normal operation of the production, the black liquor extraction rate of the two pulps has been improved, and the alkali loss rate has been greatly reduced.
