摘要： A method for treatment of sludge is disclosed, wherein the sludge has a liquid part and metal-containing particles intermixed therein. The particles comprise metal, metal oxide or metal hydroxide and the method comprises the following steps: atomising the sludge; supplying the atomised sludge to a flame of a burner provided in a furnace; bringing the liquid part of the sludge to vaporise by means of the flame while maintaining said flame by means of a separate fuel supply; and bringing at least part of the metal-containing particles to melt by means of the flame. This provides an efficient method for taking care of waste material from plants in the steel or petrochemical industry, for example.

摘要： A method for the treatment of cellulose fibres in a pulp stream (22) comprises the following steps. A pulp is prepared (21). The pulp is subjected to a bleaching, comprising at least a bleaching step (25, 30) by the addition of an oxidizing bleaching agent. After the bleaching, liquid is removed (28, 33) from the pulp while obtaining a residue liquid and at least a part flow of the residue liquid obtained is conveyed back to the pulp stream (22) via a transport conduit by means of a pump device. Said part flow of the residue liquid is treated by oxygen (45) by the supply of oxygen to the part flow downstream of the pump device.

摘要： A semiliquid or liquid food product is frozen in pieces by chilling an impervious support (2) as well as at least one cutter blade (12) arranged to be moved into contact with the support, to a sufficiently low temperature to freeze a food product, upon its contact with the support and the cutter blade, over the entire surface of contact of said product without the latter freezing fast thereto. The cutter blade is lowered into contact with the support while cutting through the food product (11) dispensed onto the support, and is removed from the food product dispensed onto the support as soon as a layer of said product closest to the support and to the cutter blade has frozen and formed a supporting bottom and one or several side walls that are contiguous with the bottom. The finally formed discrete pieces are removed from the support for final freezing thereof in a second freezer.

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.
