摘要： The disclosure relates to a method in processing, in particular the treatment of cellulosic materials, in a treatment zone with a gas in a liquid, the gas being added to the liquid and being transported therewith to the treatment zone. The method according to the present invention is characterized in that, to increase the capacity of the liquid to retain and transport the gas, the foaming properties are improved and/or particles are added to the liquid with a capacity to retain gas bubbles. The foaming properties of the liquid may be increased by adding foaming agents, by deactivating and/or removing ions which hamper or hinder present foaming agents from forming foam, by deactivating and/or removing ions by means of complex formers, deposition agents or ion exchangers or by adding cellulosic fibres.

摘要： The invention relates to a method pertaining to the bleaching of secondary fibres. Bleaching of secondary fibres includes a refining stage in which the pulp is worked mechanically in a pulp processing apparatus (1), and a bleaching stage which is carried out in a bleaching tower (8). In the mechanical processing stage, which may be carried out in a disc disperser, oxygen (12) is delivered to the pulp (1) through an oxygen delivery line (5), directly into the centre of the apparatus, so as to disperse the oxygen uniformly and finely throughout the pulp (m). This energy supply enables the consumption of peroxide to be maintained at a very low level, or enables a very high brightness to be achieved.

摘要： The invention relates to a method for recovering non-ferrous metal from a dross starting material containing this metal, optionally together with non-ferrous metal scrap, and/or a starting material comprised of such scrap. The method comprises introducing the starting material into a rotary furnace or rotatable converter provided with a refractory lining, heating the starting material to a temperature above the melting point of the metal while rotating the furnace either continuously or intermittently, and removing the resultant molten metal from beneath the overlying dross residues. The method is characterized by heating the starting material in the absence of a protective salt layer with the aid of a so-called oxy-fuel-burner which is supplied with a fossil fuel and with a gas that contains at least 80 % oxygen, and by rotating the furnace at a speed of 5 r.p.m or lower.

摘要： There is described a method for treating delimed and bated hides, i.e. pelts. According to the inventive method, the pelts are brought to a suitable mineral tanning state and then tanned with mineral salts. The inventive treatment process corresponds to the conventional processes of pickling, tanning and basifying. The inventive method includes the treatment of pelts with weakly acid treatment liquids while supplying carbon dioxide and additions of tanning mineral substances subsequent to pretreatment, without or with the addition of solely a small amount of liquid, wherein the quantity of treatment liquid is supplemented after a predetermined treatment time.

摘要： The invention relates to a blasting method for removing coatings of paint, varnish or like substances from objects coated with such substances, in which the objects are cooled in a condensed gas, e.g. liquid nitrogen, and then subjected, in a chilled state, to the effect of a blasting agent, e.g. steel shot, delivered by a blasting machine. The coating fragments dislodged are collected together with the blasting agent and mutually separated one from the other in a separator. The recovered blasting agent is then returned to the blasting machine. The method is characterized by adding an absorbent to the blasting agent in the blasting machine.
