Abstract: Method of forming a fibre web (210) intended for use in absorbent products, such as sanitary towels, by air-laying fibres. Separate air flows containing fibres are fed to a number n of different mat-forming wheels (160, 170, 180), where n is a whole number which is at least 2. Separate web layers (161, 171, 181) are formed on each mat-forming wheel. The fibre web (210) is formed by virtue of said web layers being combined downstream of the mat-forming wheels to form a common fibre web which is imparted very great manufacturing accuracy by virtue of the manufacturing method. The manufacturing speed and thus the web speed can be very high, and the desired manufacturing accuracy at the web speed concerned is achieved by selecting a sufficiently great number n of mat-forming wheels. The invention also relates to a fibre web manufactured according to the method. <IMAGE>

Abstract: Treating and venting gaseous nuclides in the gas space above the liquid level in tanks containing radioactive liquid is accomplished by connecting the gas spaces in series with the gas space at one end having the highest radioactivity, normally discharging at a limited rate into a waste gas system, and air to replace the discharged gas, introduced into the gas space at the other end. Sudden surges or fluctuations in gas pressure in the gas spaces due to rapid filling of the tank with liquid is relieved by discharging gas from the gas space of low activity at the other end into a stack. Voids in the tanks created by rapid emptying of the tanks is filled by air entering the gas space of low activity at the other end. A self cleaning filter which removes nuclides from the gas before entering the stack is reactivated by the passage of air in a reverse direction through the filter with the return of the nuclides to the gas space of low activity. The system permits longer holding time of nuclides, greater assurance of unwanted nuclides not entering the stack, and means for compensating for surges in the gas space without disturbing the operation of the waste gas system.

Abstract: Urea is produced form a gaseous mixture of H2, N2 and CO2, e.g. that obtained by the steam reforming of hydrocarbons. Carbon dioxide is absorbed from the mixture by the action, firstly, of an aqueous ammonia solution (e.g. above 70% by weight) and, secondly, of an ammonia-containing solution of ammonium carbonate, a solution of ammonium carbamate thus being obtained, together with a gaseous stream of nitrogen and hydrogen. The carbamate solution is passed to a urea reactor to obtain a urea solution containing unconverted carbamate and excess ammonia. The carbamate is decomposed and the evolved ammonia is recycled to the urea reactor along with carbon dioxide. The urea solution, now containing a reduced amount of carbamate (e.g. 50% of its original content), is passed to an adiabatic stripper in which the stripping gas used comprises hydrogen and nitrogen obtained from the CO2-absorption stage. Decomposition products together with water are removed from the adiabatic stripper, and are condensed in the presence of ammoniacal ammonium carbonate and the condensate so obtained is passed to the CO2-absorption step. <IMAGE>
