    Abstract: Uso de una columna para purificación por destilación de anhídridos de ácido carboxílico, donde la columna comprende un circuito del fondo en el cual se aloja un evaporador (21), así como una bomba (23) para llevar el producto sacado en el fondo a través del evaporador (21) y de vuelta a la columna, caracterizado porque la bomba (23) es una bomba de acoplamiento magnético en la cual se forma, en el perímetro externo del rotor (25), un soporte de imanes (27) que se extiende en dirección axial y el rotor (25) se cierra por el lado opuesto al sitio de succión con un recipiente de contención (39) y porque entre el soporte de imanes (27) y la carcasa (37), así como entre el soporte de imanes (27) y el recipiente de contención (39) se forma una hendidura por la cual fluye el líquido que va a impulsarse con la bomba (23).

    Abstract: A method (M1) for mixing liquids or mixtures of liquids and finely-divided solids (I) in a closed tank where (I) fills only part of the available volume and the rest is filled by gas, by feeding in the same liquid or mixture (I) as a propulsive jet from a nozzle with a pulse-exchange space containing the jet nozzle outlet, in which the intake zone between jet nozzle and pulse-exchange space (PES) has a casing with at least one intake which is below the central jet leading from the nozzle to the PES. Independent claims are included for (1) a jet nozzle as above in which the casing has at least one intake opening into a dip tube or at least one connection for such a tube (2) a mixing method (M2) as above in which a different liquid or mixture is fed in as a propulsive jet .

    Abstract: Mixing a liquid or suspension beneath a gas space in a closed container comprises supplying a stream of the liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container. Independent claims are also included for: (1) container comprising a liquid or suspension beneath a gas space and an ejector with a drive nozzle and a suction chamber in communication with the gas space; (2) container comprising a liquid or suspension beneath a gas space and an ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, and a connection between the suction chamber and the gas space; (3) ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, where the transition between the mixing nozzle and the impulse exchange chamber is provided with a jacket fitted with a dip pipe or a connector for a dip pipe; (4) mixing a liquid or suspension beneath a gas space in a closed container by supplying a stream of another liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container.

    Abstract: The invention relates to a column (1) for purification by distillation of carboxylic acid anhydrides, comprising a bottoms circulation stream in which an evaporator (21) is accommodated, and a pump (23), in order to direct product removed from the sump through the evaporator (21) and back into the column. The pump (23) is a magnetically coupled pump, in which a magnetic holder (27) extending in the axial direction is formed on the outer circumference of the rotor (25), and the rotor (25) is closed by means of a containment shell (39) on the side opposite the suction side.
