PROCESS AND DEVICE FOR THE GENERATION OF A CONSTANT AMOUNT OF STEAM FROM THE WASTE HEAT OF AN ALKANE DEHYDROGENATION PROCESS

The invention relates to a process and a facility for an as constant as possible supply of steam flow from an alkane dehydrogenation, the process being carried out by passing a hydrocarbonaceous gas through reaction tubes loadable with a catalyst, and the reaction tubes, which are sealed towards the...

Beschreibung
Zusammenfassung:	The invention relates to a process and a facility for an as constant as possible supply of steam flow from an alkane dehydrogenation, the process being carried out by passing a hydrocarbonaceous gas through reaction tubes loadable with a catalyst, and the reaction tubes, which are sealed towards the outside, running through a heating chamber which is heatable by means of burners, and the catalyst being regenerated for the reaction in a cyclic operating mode, in which the reaction is endothermic and the regeneration of the catalyst non-endothermic, and the capacity of the main burners is reduced during the regeneration of the catalyst, in which auxiliary burners, which serve to keep up the production of hot flue gas during the regeneration of the catalyst, are installed at the inlet of the flue gas duct to produce additional hot flue gas which is used for generating an as constant as possible amount of steam from the waste heat of the process.
