摘要： A blast furnace process and plant are provided employing a gas mixture comprising coke oven gas and gasified fine grained to dusty fuels. The mixture is produced in a mixing chamber wherein the raw gas from the gasifier is chilled with purified cool coke oven gas. The gas mixture is separated from dust and desulfurized in a cyclone charged with burn lime dust. Then the gas mixture is fed to the blast furnace proper and enters at temperatures from about 750.degree. C. to 1000.degree. C.

摘要： The invention relates to a process for recovering the sulfur components of acidic gases collected by gas desulfurization. The inventive concept is to first compress a stream of the acidic gas (known as "acid gas") up to a pressure of 8.00 to 12.00 atmospheres absolute. Then this compressed stream of gas is cooled to -35.degree. to -45.degree. C. The pressure on this cooled gas is reduced to a pressure of 1.05 to 2.00 atmospheres absolute. Subsequently, the gas is further cooled to a temperature of -55.degree. to -65.degree. C. Finally, the resulting mixture is conducted to a separator where frozen solid constituents are separated from the gaseous constituents. The gaseous constituents include substantially all of the sulfides produced during the gas desulfurization and the frozen solid particles consist essentially of carbon dioxide.

摘要： An apparatus for removing harmful substances from effluents has two chambers located symmetrically at opposite sides of an effluent channel. Each chamber contains two or more stacked trays which are each provided with a spiral flow path descending from a tray inlet to a tray outlet. All tray inlets are so located in the channel that substantially all effluent flowing in the channel is compelled to enter them and to travel by gravity through the respective tray. Air, an insert gas or a mixture of both is bubbled from below through the effluent flowing in the trays to expel and entrain the harmful substances. The treated effluent is then discharged back into the channel at locations downstream of its point of admission into the inlets.

摘要： A carbon monoxide-rich gas of a carbon monoxide concentration of at least 98% by volume is produced by[a] generating a hydrogen and carbon monoxide-containing crude gas by gasification of a finely divided solid fuel, including dust-like fuel, with oxygen or oxygen-enriched air and steam;[b] desulfurizing the crude gas;[c] removing any carbon dioxide present in the crude gas by a selective wash;[d] subjecting the thus-treated crude gas to a low temperature decomposition into a carbon monoxide fraction, a hydrogen fraction and a fraction constituted by the residual gases;[e] carrying out an endothermal catalytic conversion of the hydrogen fraction by reaction with the carbon dioxide removed in step [c] from the crude gas, the carbon monoxide-rich gas occurring in said conversion reaction, after elimination of the condensate, being recycled into the crude gas at a place preceding said carbon dioxide removal (step [c]), while[f] recovering the formed carbon monoxide-rich gas fraction for further use and discharging the residual gas fraction into the atmosphere. The process permits to use solid fuels instead of the gaseous or liquid hydrocarbons usually used in prior art processes.

摘要： After replacement of the walls of one chamber of a coking battery this one chamber is heated up by withdrawing relatively hot air from another still-hot chamber of the coking battery and injecting it into the cold chamber. This is done by means of a conduit extending between the two chambers and provided with an internal nozzle that conducts the hot gas from the hot chamber to the cool chamber by jet-pump action. This hot gas is mixed with relatively cool air so as slowly to heat the cool chamber up.

摘要： Ammonia and 5 to 40 volume percent hydrogen sulfide containing vapors which arise in the vaporization of process water from hydrogenation or a crude oil fraction or in gas treatment in a coking plant, can be subjected in a cracking catalyst reactor to breakdown of the ammonia to nitrogen and hydrogen. The resulting process gas is cooled to 250.degree. to 350.degree. C. and is fed to a hydrogenation reactor where any sulfur is hydrogenated to the hydrogen sulfide. The process gas can then be subjected to further treatment without the danger of sulfur blockage of the process lines. For example, the hydrogen sulfide can be removed by a selective absorption process.

摘要： In the process for purifying an aqueous MDEA-solution the formate content of the MDEA-solution circulated in a main stream between the absorber and desorber of a hydrogen sulfide wash unit for gas produced by gasification of a carbonaceous material, e.g. coal, is measured. A partial stream of MDEA-solution is withdrawn from the main stream, passed over an ion exchange medium which removes some formate present to form a partially purified partial stream and subsequently the purified partial stream is returned to the main stream. The amount of the withdrawal from the main stream is controlled so that the formate content of the main stream is maintained between 10 and 30 g/l. Only from 0.5 to 0.08% by volume need be withdrawn from the main stream to form the partial stream. The ion exchange medium can be regenerated with a hydroxide-containing solution, which is subsequently fed to an ammonia separator column of a hydrogen sulfide wash apparatus.

摘要： The process for cooling of partial oxidation crude gas includes partially oxidizing a fine grained to powdery combustible material in a flow gasifier in the presence of water vapor and an oxidizing member selected from the group consisting of oxygen and air at pressures of up to 100 bar and at temperatures above a cinder melting point to form a crude gas flow; feeding the crude gas flow in a crude gas duct in an upward crude gas flow direction; and feeding an annular cooling flow of a gaseous or vaporous cooling fluid into the crude gas flow in a downward direction opposite to the crude gas flow direction, the annular cooling flow being bounded by interior walls of the crude gas duct. In a preferred embodiment the annular cooling flow is fed into an upper quenching chamber having a diameter smaller than a downstream connected lower quenching chamber through which the crude gas flows so as to prevent upward extension of any growing cinder layer.
