摘要:
To effectively utilize coal ash while reducing mercury concentration in cement kiln exhaust gas. Coal ash is received from a thermal power plant or the like; the received coal ash is separated into ash and unburned carbon; the separated ash is utilized in a cement manufacturing facility as a cement raw material; and the separated unburned carbon is utilized in the cement manufacturing facility in accordance with mercury concentration in gas exhausted from a cement kiln of the cement manufacturing facility. In case that the mercury concentration in the gas exhausted from the cement kiln of the cement manufacturing facility is high, in the coal ash, unburned carbon with high mercury content can be treated in facilities other than the cement manufacturing facility without feeding the unburned carbon to the cement manufacturing facility, or the quantity of such unburned carbon fed to the cement manufacturing facility can be adjusted. It is possible to separate mercury from the separated unburned carbon, and utilize the unburned carbon from which mercury is separated in the cement manufacturing facility as a fuel.

The present technique relates to an information processing device, an information processing method, a recording medium, and a program capable of extracting the structure of time series data. An acquisition unit acquires time series data, a conversion unit converts the obtained time series data into an RAR model, and a prediction unit predicts the future of an event that is currently in progress using the RAR model. The present technique can be applied when predicting the future of a phenomenon that changes with time such as weather, earthquake, natural environment, human health, and economy from time series data.

To reduce cost of chemical by reducing quantity of foaming agent used when removing unburned carbon in fly ash with wet floatation and to prevent decrease in activity index of the fly ash. In wet decarburization of fly ash, the solution comprising the steps of: adding water to fly ash to generate slurry; adding hydrophobizing agent and foaming agent to the slurry and agitating them to generate bubbles; and adhering unburned carbon in the fly ash to the bubbles to float them to remove the unburned carbon in the fly ash, when sedimentation component at wet floatation separation is solid-liquid separated and liquid phase obtained by solid-liquid separation is reused for another floatation separation for new fly ash, the quantity of foaming agent added to the slurry is adjusted such that concentration of the foaming agent in liquid phase is in a predetermined range. When adjusting the concentration of the foaming agent in the liquid phase, it is possible to measure COD concentration in the liquid phase and adjust the quantity of the foaming agent added to the slurry in such a manner that the COD concentration is in a predetermined range.

摘要:
To provide a cement manufacturing apparatus and the like capable of increasing quantity of fly ash used in the apparatus while controlling unburned carbon content in cement within a permissible range. The cement manufacturing apparatus and the like comprises a removal means for removing unburned carbon from gypsum, and a grinding means for grinding gypsum from which unburned carbon is removed by the removal means together with clinker to generate cement. With the apparatus, total unburned carbon content in cement can be reduced, and the quantity of fly ash used in the apparatus can be increased by the reduced amount of unburned carbon. The removal means can remove unburned carbon contained in gypsum as well as unburned carbon contained in fly ash, and the grinding means may grind the fly ash from which unburned carbon is removed together with the gypsum, from which unburned carbon is removed, and clinker. The removal means may simultaneously remove unburned carbon contained in gypsum and unburned carbon contained in fly ash.

A method of manufacturing aromatic urethanes utilizes a urea production process wherein a primary aromatic amine, an aromatic nitro-compound and carbon monoxide are made to react together in the presence of a catalyst and solvents, to produce N,N'-disubstituted urea, the solvlent used in the urea production process consisting at least partly of an amide or oxygen-containing sulfur compound, and having the functions of stabilizing the catalyst and preventing it from separating out in a solution, and of increasing the activity of the catalyst, the quantity of the solvent being sufficient to permit it to fulfill these functions effectively. The method additionally includes an aromatic urethane production process wherein the N,N'-disubstituted urea produced is made to react with an organic compound containing hydroxyl groups, to produce a primary aromatic amine and aromatic urethane, the primary aromatic amine being separated to obtain the aromatic urethane.
