The present invention provides a method of controlling a chemical process, the method comprising the steps of : (i) providing a laminar flow of a first fluid, the first fluid providing a first reagent or one or more precursor thereof) ,a laminar flow of a second fluid, the second fluid providing a second reagent (or one or more precursor thereof) and a laminar flow of barrier fluid; and (ii) causing the first and barrier fluids to contact one another so that the barrier fluid forms a barrier between the first reagent (or one or more precursor thereof) and the second reagent (or one or more precursor thereof) wherein step (ii) comprises forming segments of first fluid encased or sandwiched by barrier fluid, the segments being surrounded by the second fluid, and the barrier fluid is permeable to one or both of the first and second reagents. Devices for performing the method of the present invention are also provided.

La présente invention porte sur un procédé de commande d~un processus chimique, le procédé comprenant les étapes consistant à : (i) fournir un courant laminaire d~un premier fluide, le premier fluide fournissant un premier réactif (ou un ou plusieurs précurseurs de celui-ci), un courant laminaire d~un second fluide, le second fluide fournissant un second réactif (ou un ou plusieurs précurseurs de celui-ci) et un courant laminaire de fluide de protection ; et (ii) conduire le premier fluide et le fluide de protection à venir au contact l~un de l~autre de sorte que le fluide de protection forme une barrière entre le premier réactif (ou un ou plusieurs précurseurs de celui-ci) et le second réactif (ou un ou plusieurs précurseurs de celui-ci), l~étape (ii) consistant à former des segments de premier fluide confinés ou pris en sandwich par le fluide de protection, les segments étant entourés par le second fluide, et le fluide de protection étant perméable au premier réactif et/ou au second réactif. L~invention concerne également des dispositifs permettant de réaliser le procédé de la présente invention.
