Abstract:
Device for distributing a fluid in a controlled manner, in particular for distributing a gas loaded with particles, the device comprising a pipe (1) provided with at least one inlet orifice (2) and with a series of outlet orifices (3) spread along the pipe (1) and cut in the side wall of this pipe, characterized in that at least one section (4) of the wall, located downstream of at least one outlet orifice and limited by a section (5) of the edge of this orifice, has a shape such that this section of the edge of this orifice is positioned inside the pipe so that, when the device is in service, the flow direction of the fluid exiting this orifice and travelling along said wall section is controlled by the shape of the latter section.
Abstract:
The invention relates to a method for producing a gas flow comprising oxygen for the endothermic reaction of a starting flow, comprising one or more hydrocarbons, with a predefined concentration of oxygen and a predefined temperature, characterized in that a fluid fuel flow is burned with a primary air flow, with λ-values of the primary air flow to the fluid fuel flow ranging between 0.6 and 1.2, while preserving a combustion gas flow, and that a secondary air flow is mixed to the combustion gas flow, while preserving the gas flow comprising the oxygen for the endothermic reaction, wherein the volume flow and the temperature of the secondary air flow are used to adjust the predefined concentration of oxygen and the predefined temperature of the gas flow comprising the oxygen.
Abstract:
The invention relates to a method for producing melamine by means of pyrolysis of urea in a high-pressure reactor with a vertical centre tube, wherein the melamine flows from the bottom to the top of the reactor, is mixed in the lower part of the reactor with a urea melt introduced into the reactor from below and, optionally, NH3, the melamine is discharged from the centre tube in the upper part thereof, part of the melamine thus formed flows downwards in the annulus between the centre tube and the reactor wall, the remaining part being transferred outwardly for further processing and the off gases are separated. The invention also relates to a reactor for carrying out said method.
