20140048480 | METHOD AND APPARATUS FOR FOR BIOLOGICALLY TREATING COKING-PLANT WASTEWATER - The invention relates to a process for the biological purification of coking plant wastewater that is loaded with nitrogen compounds, cyanides, phenols and sulphides. The coking plant wastewater, for removal of pollutants that inhibit a nitrification, is fed together with a biomass-containing stream of matter to a detoxification reactor that has a gas-treatment zone and a reaction zone. The feed mixture supplied to the detoxification reactor is exposed in the gas-treatment zone to a gaseous oxidizing agent. A stream of matter enriched with the oxidizing agent is fed to the reaction zone in which cyanides and other pollutants inhibiting the nitrification are biodegraded. A stream of matter is withdrawn from the reaction zone and returned to the detoxification reactor. In addition, a wastewater stream from the detoxification reactor is separated by a membrane filtration into a biomass-containing retentate stream and a purified permeate stream. From the retentate stream, a substream which entrains excess sludge is discharged. The retentate stream, after separating off the substream, is recirculated to the detoxification reactor. The permeate stream is further purified by nitrification and subsequent denitrification. | 02-20-2014 |
20140251784 | PROCESS FOR DRY COOLING OF COKE WITH CARBON DIOXIDE WITH SUBSEQUENT USE OF THE CARBON MONOXIDE PRODUCED - A process for dry cooling of coke with carbon dioxide with subsequent use of the carbon monoxide produced, in which the coal is cyclically converted to coke and the coke, after the coking oven has been unloaded, is introduced into a cooling apparatus, and carbon dioxide is introduced in the cooling apparatus for dry cooling, such that a Boudouard reaction gives rise to carbon monoxide, and the carbon monoxide produced is used to heat the coking oven. The process allows utilization of the heat which arises in the course of coking for production of carbon monoxide, which in turn is used in the heating, such that a very balanced heat budget of the overall process can be achieved overall. | 09-11-2014 |
