A reactive composition comprising between 60% and 98% by weight of sodium bicarbonate, between 1% and 40% by weight of sodium carbonate and between 0.02% and 2.0% by weight of ammonia, expressed in the form of ammonium ions NH, and comprising from 0.01 to 5% by weight of a compound selected from the group consisting of hydrocarbons, fatty alcohols, fatty acids, and fatty acid salts.

Reactive composition based on sodium bicarbonate and process for its production

A device for distributing a fluid in a controlled manner, in particular for distributing a gas loaded with particles, the device comprising a pipe () provided with at least one inlet orifice () and with a series of outlet orifices () spread along the pipe () and cut in a side wall of this pipe, wherein at least one section () of the side wall, located downstream of at least one outlet orifice and limited by a section () of the edge of the outlet orifice (), has a concave shape such that this section () of the edge of such outlet orifice () is positioned inside the pipe so that, when the device is in service, the flow direction of a fluid exiting such outlet orifice () and travelling along such deformed concave wall section () of the edge of this outlet orifice () is controlled by the shape of such section () of the edge.

Device for distributing a fluid in a controlled manner, in particular for distributing a gas loaded with particles, the device comprising a pipe () provided with at least one inlet orifice () and with a series of outlet orifices () spread along the pipe () and cut in the side wall of this pipe, characterized in that at least one section () of the wall, located downstream of at least one outlet orifice and limited by a section () 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.

Process for milling a substance selected from sodium carbonate, sodium bicarbonate and sodium sesquicarbonate or trona, in which a cleaning agent is introduced into a mill for the purpose of obtaining a powder with a mean diameter of less than 100 &#x3bc;m and of inhibiting the formation of incrustations in the mill.
