Elevated temperature liquid testing apparatus and methodology in which a thin film of test liquid and a reactant/control gas are provided about the top of a depositor member that is surrounded by a special mantle, for example, a substantially cylindrically walled glass mantle. As an oxidative engine oil test, it may mimic turbocharger conditions of a modern internal combustion engine. For example, employing moist air, the apparatus can test a thin film of engine oil for oxidation deposits at a predetermined temperature, say, 285 C., 290 C., or cycled between 285 C. or 290 C. and 320 C. or 330 C.

A continuous falling film reactor includes a reactor body including chambers for a reaction between first and second reagents. The chambers have a respective inner surface, for the sliding of the first reagent in the form of a thin film, or layer, a device for introducing the first reagent, in particular in the liquid phase, especially in the form of an organic raw material, into the respective chamber and a device for inputting the second reagent, in particular in the gaseous phase, especially in the form of sulphuric anhydride, in the respective one of the chambers. A head introduces the first reagent, in the respective chamber, which headincludes a corresponding nozzle so calibrated to cause a predetermined load loss of said first reagent.

A wetted-wire liquid-gas contactor device is disclosed comprising a plurality of wires, a first support structure configured to retain the plurality of wires, and a liquid distribution system for receiving and distributing a liquid to the plurality of wires. The diameter of the plurality of wires is approximately 2 mm or less, wherein a pitch of the plurality of wires is less than 4.0 mm.

System and process for uniform distribution of liquid organic substance in thin layer form in a falling film reactor, defined by a plurality of tubes. It is contemplated to feed the same amount of liquid organic substance to all tubes and then distribute it uniformly as a thin layer on the perimeter of each tube and by two coupled plates and sheet interposed therebetween; the lower plate is machined to create a groove and a spillway around each hole, a slit of constant thickness.
