Title: Process for refining a metal bath containing solid cooling substances
Inventor: SCHLEIMER FRANCOIS
IPC: C21C5/32
Filed: 1980-03-25
Granted: 1984-12-06
Abstract: A process for refining a metal bath in a converter by oxygen blowing, particularly a molten metal liquid bath containing cold, solid substances, notably of scrap. Oxygen is distributed over the surface of the bath, so that there will be an after-combustion of CO released in the course of decarbonization. The thickness and consistency of a slag layer formed over the bath is actively regulated by injecting a rising inert gas through the bottom of the bath. The flow of rising gas may be regulated depending upon the oxygen content in the fumes of the converter, or upon the intensity of emission through the top of an oxygen blowing lance.

Title: A method for separating gaseous, elementary mercury and gaseous halogenides of mercury and other heavy metals from a gas
Inventor: WIKLUND JOHAN ELOF
IPC: B01D53/34
Filed: 1982-05-05
Granted: 1985-09-26
Abstract: The invention relates to a method for separating gaseous elementary mercury from a gas in conjunction with a wet-gas cleaning process comprising a plurality of washing stages. The mercury-containing gas is treated with an aqueous washing liquid conducted in a closed circuit, the liquid containing 0.1-300 mmol/1 mercury (II) ions and at least twice this amount of ions having the ability of forming complexes with mercury (II) ions, the mercury in the gas being oxidized and absorbed in the washing liquid. The invention is characterized in that the treatment process is carried out in conjunction with a gas-cooling process effected after the last washing stage of the wet-gas cleaning process, to form a condensate for absorbing the halogens contained in the gas. The resultant condensate is transferred to the washing liquid and the mercury (II) content of the washing liquid is maintained by contacting the washing liquid with an oxidizing agent for mercury (I) ions. The agent used to oxidize mercury (I) ions is preferably chlorine gas.

Title: A method of polysulphide treatment in alkaline pulping of lignocellulose material
Inventor: MANNBRO NILS V
IPC: D21C1/06
Filed: 1982-10-13
Granted: 1987-02-05
Abstract: Preparation of polysulphide for treatment of wood chips so that the wood consumption is reduced in kraft digestion of paper pulp. In an impregnation stage the wood chips are caused to react with black liquor, or black liquor components containing digestion liquor prepared of white liquor, while introducing oxygen of appropriate concentration in an impregnation vessel. The content of monosulphide, and to a certain extent other sulphur compounds present in the liquors, thereby forms polysulphide in contact with the wood chips which instantaneously absorb the polysulphide. Generation of polysulphide is promoted by wood reactions. Black liquor having a reduced concentration of hydroxide is withdrawn from the wood chips before delignification thereof in digestion liquor prepared of white liquor and residual impregnation liquor from the wood chips. The withdrawn black liquor is conveyed to a plant for regeneration of hydroxide in white liquor and sulphide, which wholly or partly is recovered in the form of white liquor, and which sulphide is repeatedly polysulphide-oxidized. The yield increment of pulp from the digester, as well as after the bleaching stage, is greater in oxidative polysulphide processing in presence of wood chips than in separate processing thereof in liquor before the charging into wood chips. This is interpreted such that more polysulphide is formed in the presence of chips than without.

Abstract: In a method of making coke in coke-ovens of a coke oven battery, the coke temperature is measured using at least one infra-red sensor after pushing of the coke from a coke-oven and before quenching of the coke. A value corresponding to the difference between measured value of the coke temperature and a predetermined reference value is determined for each of a plurality of coke loads pushed from a series of coke-ovens. The mean of said difference values is determined and the combustion gas supply to at least a plurality of coke-ovens of the battery is adjusted in dependence on said mean of the difference values. In this way, better control of the temperature of the coke at the end of the coking time can be achieved, with less deviation of the coke temperature from the reference value.
