摘要： The present invention provides a method for precipitating (separation) of lignin, using small amounts of acidifying agents, whereby a lignin product or an intermediate lignin product is obtained which can be used as fuel or chemical feed stock (or as a chemical or a raw material for further refining), from a lignin containing liquid/slurry, such as black liquor. The present invention also provides a method for separation of lignin from a lignin containing liquid/slurry, such as black liquor, whereby a more pure lignin is obtained. The present invention also provides a lignin product or an intermediate lignin product obtainable by the above methods. The present invention also provides use, preferably for the production of heat or for use as chemical, of said lignin product or intermediate lignin product.

摘要： The present invention relates to a method for separation of lignin from original black liquor (BL IN ) comprising a first precipitation phase (PR1/PR2) for precipitation of lignin by a first acidification using acidifier, CO 2 , at alkaline conditions, then separating a lignin cake with subsequent suspension of the lignin cake in a strong acid in order to leach our metals from the lignin followed by dewatering and obtaining a clean lignin product LP. According to the invention are lignin germ particles (LG) added to the original black liquor in the first precipitation stage, preferably between two phases in said precipitation stage, in order to increase lignin particle growth on such lignin germ particles instead of spontaneous nucleation of lignin particles in said original black liquor. This will result in improved filterability in subsequent dewatering and lignin cake formation and hence an increased lignin yield.

摘要： In a process of treating wood chips for reduction of the concentration of undesirable inorganic elements prior to cooking in a production line for chemical pulp, the wood chips, having entrapped air, are treated with an aqueous leaching liquor at elevated temperature and pressure, followed by draining at atmospheric pressure or below atmospheric pressure, the pressures being controlled to yield a moisture content in the wood chips as low as possible for adequate leaching result and behavior of the chips in a subsequent digester. The aqueous leaching liquor is e.g. pulp mill process water with a low content of undesirable inorganic components, such as bleach plant spent liquor or condensate. The aqueous leaching liquor drained from the treated wood chips may be purified and recycled back to the process.
