    摘要： The invention is characterised in the steps of a) performing a first separation of the mixture in a first centrifugal separator, resulting in a first heavy fraction comprised of the heavy phase with only small amounts of impurities in the form of the light phase and a first light fraction comprising of the light phase with impurities in form of the heavy phase; and b) performing a second separation of the first light fraction in a second hermetic centrifugal separator of purificator type, resulting in a second heavy fraction comprised of the heavy phase with impurities in the form of the light phase and a second light fraction comprised of the light phase with only small amounts of impurities in the form of the heavy phase. The invention also relates to a device.

    摘要： Separation of a product of digestion of cellulosic biomass solids may be challenging due to the various components contained therein. Methods and systems for processing cellulosic biomass, particularly a reaction product of a hydrothermal reaction containing lignin-derived products, such as phenolics, comprise providing the reaction product to a separation zone comprising a liquid-liquid extraction unit. The liquid-liquid extraction unit can provide an aqueous portion and a non-aqueous portion, where these portions can be separated into various fractions individually. For example, desirable compounds in the aqueous portion and non-aqueous portion can be recovered from the portions individually and optionally combined to be further processed into a fuels product. Heavier components in the aqueous portion and non-aqueous portion can be recovered from the portions individually and used in the process, such as phenolics that can be used as a digestion solvent.

    摘要： The method is for separation of lignin from original black liquor (BLIN) that has a first precipitation stage (PR) for precipitation of lignin by a first acidification using acidifier AC1, preferably using CO2, 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. The process further is improved by intensified hydrolysis of lignin cake such that most of the carbohydrates are broken down to dissolvable monomers that could be separated from the lignin in the filtrate from a filtering stage subsequent to the hydrolysis. The improved hydrolysis could reduce as much as 90% of the carbohydrate content using a moderately increased temperature and increased charge of acidifier while avoiding any larger lignin yield losses.

    摘要翻译： 该方法用于将木质素与原始黑液（BLIN）分离，其中第一沉淀阶段（PR）用于在碱性条件下使用酸化剂AC1（优选使用CO 2）进行第一次酸化沉淀木质素，然后分离木质素饼 将木质素饼块悬浮在强酸中以从木质素中浸出我们的金属，随后脱水并获得干净的木质素产物LP。 该方法进一步通过木质素饼的强化水解进一步改善，使得大多数碳水化合物被分解成可溶解的单体，其可以在水解后的过滤阶段从滤液中的木质素中分离出来。 改善的水解可以使用适度升高的温度和增加酸化剂的电荷来减少多达90％的碳水化合物含量，同时避免任何更大的木质素产率损失。

    摘要： The process for treating a ligno-cellulosic biomass feed stream comprised of solids, C5's, C6's, lignin, and water comprises the steps of: pretreating the ligno-cellulosic biomass feed stream by contacting the ligno-cellulosic biomass with water in the temperature range of 40 to 210 ° C. to create a pre-treated ligno-celluosic biomass comprised of a pre-treatment ligno-cellulosic biomass liquid comprised of suspended solids, C5's, C6's, and acetic acid, wherein the ratio of the C6's to C5's is less than 0.8 to 1.0, and a pre-treated ligno-cellulosic biomass solids; separating a portion of the pre-treatment ligno cellulosic biomass liquid from the pre-treated ligno-cellulosic biomass feed stream; separating a portion of the suspended solids from the pre-treatment ligno-cellulosic biomass liquid using filters, centrifuge or combination thereof, to create a clarified liquid stream, and nano filtering a portion of the clarified liquid stream to create a nano-filtered permeate stream comprised of acetic acid and water and a nano-filtered retentate stream comprised of C5's, C6's, acetic acid and water, wherein the ratio of acetic acid to the total amount of C5's, C6's in the clarified liquid stream is greater than the ratio of the acetic acid to the total amount of C5's, C6's in the nano-filtered retentate.
