  • Method and device for regenerating a platinum bath
    Patent number: 10767276
    Abstract: A method of regenerating a platinum bath by flow reaction, the method comprising the successive steps of: drawing off fluid from the platinum bath by means of a draw-off flow; complexing platinum by mixing together the draw-off flow and a regeneration solution flow containing platinum, mixing taking place in an intensified reactor; and feeding the platinum bath with the mixture resulting from the platinum complexing step, by means of a regenerated bath flow; all of these steps being performed as a continuous flow.

  • Continuous oligomerization of isocyanates
    Patent number: 8378139
    Abstract: A process for oligomerizing isocyanates includes a step of continuous conversion of an isocyanate monomer into polyisocyanate containing carbamate and/or allophanate groups, in the presence of a catalyst, wherein the conversion step is carried out in a reactor having a specific heat exchange coefficient of greater than or equal to approximately 200 kW/m3/° C.

  • Optimizing a chemical reaction in a plate-type open reactor
    Patent number: 8065038
    Abstract: A method of optimizing a chemical reaction in a plate-type open reactor, the method consisting in: establishing a dynamic model of the reactor for a given reaction on the basis of a model of the reactor and its heat exchanges; applying an integration software tool to the dynamic model in order to solve the above-mentioned equations; determining and optimizing a set of dimension and/or operation parameters of the reactor on the basis of evaluating targets to be achieved, constraints to be complied with, and variable data for the reactor and/or the reaction; building a plate reactor of the said type accordingly to the set of optimized parameters; and doing measurements of physical parameters during the execution of said reaction in the built reactor, for validating its operation.
