Separate flows, or flows separated by deflection, are caused to impact. Their velocities differ and they are co- or counter-flowing. The flows translate and/or rotate. Friction results from the velocity difference. An Independent claim is included for the equipment carrying out the process. The reaction chamber (1) is heart-shaped in longitudinal section. Its cross section reduces from the supply side, being smallest at the lower end. The minimum cross sectional area of the outlet tube is less than the total area of the combined media supplies. Preferred Features: The flows are produced by separating a supply (9), or are introduced as separate flows of different media. Flows are guided through tubes or vessels containing them, such that simultaneous rotation and translation is caused. Flow velocities are selected to set up turbulent boundary layers in each medium flow to be treated. Flow velocities cause mutual friction between flows in translation and/or rotation. Flows intermix and swirl only in the boundary layer. Entrained materials or compounds are separated by choice of velocities. Molecular structural rearrangement displaces volatile foreign matter or gases included, de-gasifying the medium. The apparatus comprises a Laval nozzle forming an outlet tube, which projects into the reaction chamber. It has 0.7 times the total area of all supply nozzles. It is multi-part, with a transparent upper section projecting out of the casing. Material introduced is brought to a set reaction temperature. Catalytic coatings may be employed. Upper flows in the chamber are introduced tangentially to the walls. Angles made by the longitudinal flow axes with the axis of symmetry of the chamber are 45 deg -90 deg , the medium descending on introduction. Additions are made to the fluid just before entry. Other peripheral pre-treatment are provided, e.g. ionization or radical conversion. A number of hand adjustments are provided; alternatively mechanical, electrical, hydraulic or pneumatic actuators are employed. Several supplies may be derived from a main line by Y-branching, the outlet limbs including less than 180 deg . Supply lines have non-return valves, with opening pressure less than 0.55 bar. They also include control valves. Supply and/or outlet instrumentation (11, 12) measures continuously or intermittently, supplying digital or analog signals for evaluation and/or display. Process variables are influenced by measured values.
