In some disclosed examples, the guiding body causes at least a portion of the flow path of the gaseous medium within the reaction chamber to take the form of a cyclone flow.

A packing is provided which has an increased corrosion resistance, high chemical resistance, low flow resistance, and an increased service life in comparison with conventional packings, wherein, to this end, it is provided that the packing comprises includes a honeycomb body having first and second end faces, wherein the honeycomb body has a honeycomb structure which has a plurality of flow channels that are arranged substantially in parallel and that are adjacent to each other by means of channel walls, and wherein the honeycomb body is made from a first plastics material based on polytetrafluoroethylene (PTFE) polymer material. Furthermore, a column is proposed which comprises includes a housing that has at least one inlet, at least one outlet and one or more packings according to the invention which are preferably arranged in a flow path running from the inlet to the outlet, in succession if applicable.

A regenerative thermal oxidizer purifies a polluted gas by oxidizing a volatile organic compound (VOC) contained in the polluted gas at a high temperature by using an amount of heat of the polluted gas.

The present invention relates to a fluid purification system. The fluid purification system comprises a regenerative thermal oxidation device (RTO device) with a first combustion chamber and at least one regenerator. The RTO device is configured to purify a first fluid flow by means of regenerative thermal oxidation. Furthermore, the fluid purification system comprises a second combustion chamber separate from the RTO device, which is configured to purify a second fluid flow different from the first fluid flow by means of thermal oxidation. The fluid purification system further comprises a heat transport device configured to transport process heat from the RTO device to the second combustion chamber to set a temperature in the second combustion chamber.

The present device is a fluid bed regenerative thermal oxidizer configured to minimize dead spaces within it and eliminate the need for complex valve systems, which are typically required to move treated and untreated air across fixed beds. The present device can be a fluid bed regenerative thermal oxidizer comprising a vertical stack having a combustion chamber near its interior center and desorber shelves located within the vertical stack above the combustion chamber and adsorber shelves located within the vertical stack below the combustion shelves. Ceramic spheres can be used as heat sinks that flow from the desorber shelves, around the combustion chamber and onto the adsorber shelves and then back to the desorber shelves. In this way heat from the combustion can be captured by the heat exchange material on the desorber shelves and released to preheat untreated air on the adsorber shelves.

The disclosure concerns a system for the removal of particulate from a waste vapor stream from a hydrocarbon production process. The particulate can be removed from the waste vapor stream using a series of water streams and gravity separation.
