摘要:
Process for carrying out heat exchange reactions comprising introducing a reactant stream into a bed of catalytic material placed outside at least one double walled heat transfer tube in a heat exchange reactor contacting the reactant stream with the catalytic material in indirect heat exchange with a heat transfer medium present in the annular volume of the at least one double walled heat transfer tube, the annular volume comprising one or more spacer elements creating a helical flow path of the heat transfer medium around the inner heat transfer tube of the at least one double walled heat transfer tube. The invention also includes a heat exchange reactor for carrying out the above reaction.
摘要:
A method of loading particulate catalytic material into a reactor tube and a loading apparatus for use in the method. The method comprises providing a loading tube through which catalyst particles pass in a damped motion. The damped motion is provided by mounting a spirally formed body on the inner wall of each loading tube section. The spirally formed body is formed from a rod having an arbitrarily shaped cross-section and a maximum dimension in any direction of the cross-section of 1/25-½ of the diameter of the loading tube section. The spirally formed body in each section has a pitch, with respect to the diameter of the loading tube section, in the interval of 2-8.
摘要:
A waste heat boiler has heat exchange tubes for indirect heat exchange of a relatively hot process gas and a cooling media, and a by-pass tube for by-passing a part of the process gas; a swirl mixer ensures mixing of the cooled process gas and the relative hot process gas exiting the heat exchange tubes and the by-pass tube.

摘要:
Techniques for selectively restarting processes based on API changes are provided. Information is stored that can be accessed to identify processes that are affected by an API change. The stored information can be modified to reflect the API change and the processes that are affected can be restarted. Thus, processes that are not affected by the API change need not be restarted.
