A process for mixing a liquid stored in a vessel, in which gas is sucked in from the gas phase present above the liquid interface with a suction apparatus present in the liquid, and released into it again for the gas-induced mixing of the liquid.

Process for mixing a liquid or mixture of a liquid and a fine solid present in an essentially self-containing vessel

A process for mixing a liquid or mixture of a liquid and a fine solid present in a vessel, in which the vessel is supplied with the same liquid or the same mixture as a motive jet of a jet nozzle which is present in the vessel and has a motive jet and a momentum exchange chamber, the suction region between motive nozzle and momentum exchange chamber being provided with a sheath which has a suction orifice below the central jet leading from the motive nozzle into the momentum exchange chamber.

A process for redissociating Michael adducts which are present in a liquid F with a proportion by weight of &#x2267;10% by weight and have been formed in the preparation of acrylic acid or esters thereof in a redissociating apparatus which comprises a pump P, a separating column K with separating internals and a circulation heat exchanger UW, wherein, for the purpose of supplying the cleavage energy, the pump P sucks in bottoms liquid from the bottom space of the separating column K and, via the circulation heat exchanger UW, continually recycles it into the bottom space above the level of the bottoms liquid, and wherein the pump P is a radial circulation pump with an open impeller.

Tray column and method for mass transfer in a tray column

A method of delivering a fluid containing at least one (meth)acrylic monomer by a pump in which a pump cavity and drive compartment are separated by a separator compartment filled with a barrier medium at elevated pressure and that is sealed with double-acting slide ring packings.
