Title: Recovery of nitrocellulose from waste water obtained from final drying stage in production of nitrocellulose
IPC: C08J11/06
Filed: 1973-07-06
Abstract: 1416771 Recovering nitrocellulose SOC NATIONALE DES POUDRES ET EXPLOSIFS 6 July 1973 [18 July 1972] 32274/73 Heading BID [Also in Division C3] Residual nitrocellulose is recovered from waste water obtained by the final drying of an aqueous slurry of nitrocellulose in the manufacture thereof, by adding a cationic polyacrylamide flocculant to the water and filtering it in a rotary drum vacuum filter A, the drum screen being precoated with flocculated nitrocellulose. The precoat is obtained by mixing more flocculant with a portion of the slurry, drawn from upstream of the drying stage, and passing the mixture through the filter. The initial waste water has 0.5-4 grams/litre of nitrocellulose, but the concentration may be raised to 2-20 grams/litre in mixing tank F before pump El feeds the water to filter A. An adjustable scraper removes nitrocellulose from the drum, and reversiible endless belt G delivers it alternately to tank F, to maintain the concentration therein, and to storage tank I. A net output of nitrocellulose is removed from tank I. Tanks J and K and pump L contain and deliver to tank F a solution of the flocculant of which 3-5 grams/m<SP>3</SP> of water are used. Before the filtering step, tank F is used to mix the precoat layer of nitrocellulose slurry and flocculant solution, which is then taken by pump El to filter A. Pump C creates the suction inside the filter drum, vessel B separating liquid and gas from the drum. The flocculant may be prepared by polymerising N,N<SP>1</SP> methylenebisacrylamide and acrylamide in the presence of N,N,N<SP>1</SP>,N<SP>1</SP> tetramethylethybenediamine as catalyst.
Patent GB-872172-A (GB)
Title: Improvements relating to the separation by fractional distillation of a mixture of two liquids
IPC: B01D3/28
Filed: 1957-10-16
Abstract: A method for the separation of two components in a mixture of liquids by fractional distillation comprises heating the mixture during <PICT:0872172/III/1> flow thereof to vaporize the more volatile of the two components and then subjecting the vapours thus emitted from the mixture to a condensation step operative to condense therefrom any vapours of the other component and cause their condensate to return to the flow of mixture where the composition of the latter is substantially the same as that of the condensate, and subsequently condensing and leading away in the liquid state the vapour of the more volatile component and then separately discharging the other component.  The method is preferably carried out in a distillation apparatus which consists of a series of heated evaporation chambers 8 connected to one another end to end in such a manner as to facilitate the flow of liquids but not that of vapours and a superposed series of cooled condensation chambers 9 connected heat-conductively with the chambers by plates 5.  Each pair of chambers has a pump 4 and a pipe 6.  The liquid mixture to be separated is conveyed to the evaporation chambers 8 by a pipe 3 and the less volatile fraction is carried off by the pipe 2, while the more volatile fraction is carried off from the chambers 9 by the pipe 1.  The chambers are arranged step-wise on account of the pressure difference between them.  A float valve 7 is opened when the liquid reaches a predetermined level.  In a modification (Fig. 2, not shown) the plates 5 of Fig. 1 are each replaced by two separate plates so that the evaporation and condensation chambers are no longer in heat-conductive arrangement.  In a further modification (Fig. 4, not shown) the apparatus comprises a number of short sections constructed as chambers placed one above the other so that the condensing heat liberated on the ceilings is used for the evaporation of the liquid on the floor of the chamber above.  In an example, an alcoholic mash containing 7.3% by weight of alcohol is separated into 90% alcohol and a residue containing 0.1% alcohol.

Abstract: Lignin or an organic derivative thereof is incorporated into artificial filamentary material having a basis of cellulosic substance during or subsequent to its production.  The type of lignin insoluble in most organic solvents may be used but preferably a solution of lignin or an organic derivative thereof is added to a spinning solution from which artificial materials are made by the wet or dry process.  The formed materials may be treated, preferably while in a swollen condition with a suspension of lignin or its organic derivative, the particle size being preferably ,0005--,003 mm.  The proportion of lignin or derivative added is from 1--10 per cent or more of the cellulose derivative.  Suitable lignin derivatives are esters, ethers, e.g. acetyl, methyl or benzoyl derivatives.  Preferably the added substances are treated to reduce their colouration before use.  In examples a 25 per cent solution of cellulose acetate in acetone containg ,5 per cent of lignin or 1 per cent of acetyl lignin is spun at 180--200 metres per minute through orifices ,08 mm. in diameter, or hanks of cellulose acetate yarn are treated for 15--30 minutes in a saturated solution of lignin in 50 per cent aqueous methylated spirit at 80--90 DEG  C.  In dry spinning processes, the spinning solution and the evaporative atmosphere may contain solvents or non-solvents.  The spinning solution may also contain substances such as citric acid as described in Specification 395,694.  In wet spinning processes, the coagulating bath may contain solvents, e.g. as described in Specifications 340,324 and 340,325, or the solvents may be p  contained in the after-treatment bath as in Specification 340,437 or in the spinning solution as in Specification 340,436. Stretching processes as described in Specifications 371,343, 375,423, 375,424, and 375,425 may be employed.  The formed products may be stretched, e.g. as described in Specifications 277,089,323,790, [both in Class 2 (ii)], 370,430, and 371,461 or treated with shrinking agents as in Specification 389,823 or 403,106.
