    Abstract: The invention relates to an installation comprising a combustion chamber (15) provided with means (53) which are used to introduce the mineral load and are connected to a pre-heater (27), combustion means (55) for maintaining the chamber (15) at a temperature of between 700° C. and 900° C., means (57) for introducing a treatment gas having a controlled carbon dioxide content in order to oppose the dissociation of the carbonate in the chamber (15), and means (61) for removing the calcinated mineral load guided into a cooler (31). The chamber (15) comprises means (51) for forming a fluidised bed. The means (57) for introducing treatment gases are supplied at least partially by a line (91) or deriving part of the combustion flue gases of the chamber (15) emitted by means for discharging (21) said flue gases into the atmosphere. The invention can be used for the production of a cement-type hydraulic binder.

    Abstract: In a process for the continuous distillation of thermolabile monomers under reduced pressure in the presence of formamide in a column,the thermolabile monomers are continuously fed in liquid form, separately from formamide, into the lower part of the column up to the middle of the column,Formamide is vaporized with a vaporizer at the bottom of the column and, together with constituents having higher boiling points than the thermolabile monomers, is discharged from the bottom of the column and replaced by addition of fresh formamide,the thermolabile monomers are taken off at a side offtake in the upper third of the column, with the distillation being controlled such that the monomers contain less than 5% by weight of formamide, anda product stream containing constituents which have a lower boiling point than the thermolabile monomers is taken off at the top of the column.

    Abstract: A process for the continuous distillation of thermolabile monomers under reduced pressure in a column includesfeeding the thermolabile monomers in vapor or liquid form to the column,introducing an inert distillation aid which forms a heteroazeotrope with the thermolabile monomers into the vaporizer at the bottom of the column, but separately from the monomer feed, and vaporizing into there or feeding an emulsion of thermolabile monomers and an inert distillation aid into the vaporizer or into the column,condensing the azeotrope at the top of the column and separating it in a phase separator, taking off the thermolabile monomers and returning the distillation aid to the column or, if desired, working it up by distillation andtaking off components having a higher boiling point than the thermolabile monomers from the bottom of the column.
