Abstract: A reactor assembly for analysing the effluent stream from at least one flow-through reactor, The reactor includes a flow-through reactor for performing at least one chemical reaction. The flow-through reactor includes a reaction chamber including a reaction zone, the reaction chamber being connected to a reactor inlet for a reactant, upstream of the reaction zone and a reactor outlet for the effluent stream from the reaction zone, downstream of the reaction zone; and an analyser for subjecting the effluent stream to an analysing procedure, each reactor outlet being connected to an analyser by an effluent conduit. The reactor assembly further includes a dilution fluid supply member for adding a dilution fluid to the effluent stream, downstream of the reaction zone.

Abstract: The system comprises a tubular vessel allowing a flow of fluid through said vessel and an assembly for housing said vessel. The assembly comprises a base block having a first channel formed therein for removably housing the vessel, said first channel having first and second channel openings allowing introduction and/or discharge of a fluid into and from said first channel. The assembly also comprises a cover element having a bottom surface being releasably attachable to the first face of the base block. A first sealing element is provided between the first face of the base block and the bottom surface of the cover element, the first sealing element surrounding the first channel opening completely, and thereby sealing gastight around said first channel opening between the cover element and the base block. The system further comprises a second sealing element located in the first channel, said second sealing element sealing gastight against the inside of the first channel and the outside of the vessel.

Abstract: A batch reaction system for simultaneously conducting reactions in at least two separate reactors (CSTR reactors), is provided wherein the at least two batch reactors, containing mixing means and a fluid inlet, a fluid feed common conduit is present for feed fluid to the reactors, which is connected to the inlet of each reactor of a fluid inlet conduits, and further includes a fluid discharge common conduit which is connected to the outlet of each reactor wherein in each fluid inlet conduit and/or in each fluid outlet conduit a non-return valve is arranged to prevent contamination but can provide simultaneous reactions wherein the reactors can be easily isolated from one another during reaction.

Abstract: The present invention relates to a batch reaction system for simultaneously conducting reactions in at least two separate reactors.
