Abstract: A wet quenching tower for quenching hot coke, including a quenching chamber, having a quenching spray device above the quenching chamber for dispensing quenching water, having a flue placed on the quenching chamber, and having at least one separating device which is arranged horizontally or at a slanted angle relative to the vertical, which can be vertically permeated, and which has a plurality of lamellae. Each of the lamellae has a non-branching cross-section, flow paths being formed between each two adjacent lamellae. The flow paths formed between each two lamellae change direction multiple times and correspondingly have a serpentine shape. A method for quenching coke using the aforementioned wet quenching tower is also disclosed.

Abstract: A device and a method for cleaning emission protection installations in coke quenching towers. The emission protection installations are fixed to a support structure in the chimney of the coke quenching tower. A liquid is sprayed onto the emission protection installations by nozzles for cleaning purposes. The nozzles are arranged on at least one movable element.

Abstract: The present disclosure relates to a process and apparatus for the purification of waste water from a coke quenching tower with reduced residence time in a collecting basin. In the process and apparatus of the present disclosure, water is used for the quenching of hot coke, and the quench water is collected in a collecting basin which is sized such that it is adequate for few quenching operations. The quench water is fed to a downstream hydrodynamic purification device without requiring any additional settling operation. In the purification device, the solids are separated from the quench water by a mechanical separation processes so as to allow a space-saving arrangement of the water collecting basin without a settling basin.

Abstract: A device for flaring combustible gases, having an adjustable opening cross-section, and three tubes arranged about a common longitudinal axis. The tubes are arranged at least in some sections in a common cross-sectional plane an inner tube is designed as a gas introduction tube and has an opening that ends at the top in the vertical direction a diaphragm that can be adjusted in the cross section, through which the gas stream can be closed or regulated and which is fitted with an automatable mechanism for adjusting the opening cross-section. The device typically contains also at least one air guiding plate, feed devices for an inert gas and an ignition mechanism, thereby ensuring a high reliability for flaring the gas and a low emission of nitrogen oxides and soot. A method for operating the device which is suitable for flaring crude gases which are to be combusted is also disclosed.
