Abstract: During nanocrystalline cellulose (NCC) production, a considerable amount of sulphuric acid is used. After the separation of the NCC, the remaining solution contains sugars and residual sulphuric acid. The sugars are in the monomeric and oligomeric forms. To reduce the cost of NCC production and to produce other added-value products, the spent acid stream can be fractionated into sugar oligomers, sugar monomers, and acid. The acid can be recycled to the NCC manufacturing process after concentration. The sugar monomers and sugar oligomers can be used for the manufacturing of other valuable chemicals. Membrane nanofiltration can be used to achieve this objective. A polymeric membrane with a molecular weight cut-off in the range of 200 Dalton was employed. Using this approach, the majority of the acid was recovered in the permeate while the sugars were concentrated in a smaller stream. The sugar level in the separated acid/permeate stream was only about 3% of the original concentration. A second membrane filtration stage can be used to separate the monomeric from the oligomeric sugars. The two sugar streams can be employed in different applications to produce value-added products.

Abstract: A method was developed for: a) improving the filterability of acid-precipitated lignin from kraft black liquors, b) increasing the dry solids content of the final lignin product, c) reducing the acid requirements and d) minimizing or eliminating TRS emissions during the acidification of black liquor to produce lignin and/or the subsequent suspension of the lignin in acid and/or the washing of the lignin with acid. No major difference in the chemical composition, MWD and main functional groups was found in the lignin of the present invention compared with lignins produced by conventional methods.

Abstract: Acid hydrolysis of biomass is an important step for releasing the component sugars before converting them to fuels and/or biochemicals. During such a process, a significant amount of mineral acid, such as sulfuric acid, is used. In most cases, the residual acid is neutralized with lime before the sugar conversion step. By doing so, a waste calcium sulphate stream is generated and sent to disposal. The efficient separation of acid from the sugars would allow the recycle of the acid and make the entire process more economically viable. We found that a resin bed packed with an acid retardation resin can be used to achieve an efficient separation (i.e. 98.5% recovery of the acid) of the sulfuric acid from the sugars. The resin bed can be simply regenerated with water.

Abstract: The present invention describes a process and system of producing methanol from methanol condensates. In a preferred embodiment the condensates are biomethanol condensates from chemical pulp mills and various waste sources used to produce a purified biomethanol. Pulp condensates are rich in methanol and contain many other contaminants. Presently, most chemical pulp mills, such as Kraft pulp mills use steam stripping to remove and concentrate the methanol and burn the methanol onsite along with the contaminants. A combination of treatments that include air stripping, steam stripping, distillation and reverse osmosis is described to obtain purified biomethanol suitable for sale or use on site.

Abstract: A process for chlorine dioxide production uses waste glycerol from biodiesel plants as a reducing agent. This untreated waste stream may contain other reducing agents such as sodium chloride and methanol which were found to enhance the chlorine dioxide production. Other chemicals present in this waste stream did not affect the operation of the chlorine dioxide generator. Substituting the waste glycerol for methanol or other reducing agents helps kraft pulp mills in reducing the cost of producing chlorine dioxide while providing a use for the untreated waste glycerol stream.

Abstract: A water-based process was developed for the synthesis of aminated lignin copolymers with high MW, thermal stability and solubility in water over a wide range of p H values. The cationic lignin copolymer described herein comprises: a grafting ratio of (weight of cationic amine compound) / (weight of lignin) of 70 to 200% and a charge density of +1.4-3.0 meq/g. This cationic lignin copolymer can be used as a flocculant in numerous wastewater streams including municipal and industrial systems and sludge dewatering in the pulp & paper, mining and oil industries.
