    Abstract: A process and an apparatus for obtaining pure water from seawater, comprising: a) a raw water is provided that comprises at least one non-volatile component (salt), b) the raw water provided is passed as cooling medium into a heat exchanger, c) additional heat is supplied to the raw water that is heated in the heat exchanger, d) the raw water from step c) is fed to an evaporation zone, e) a carrier gas suitable for water vapour is provided (air), f) the carrier gas is brought into contact with the raw water in counter current flow in the evaporation zone which contains baffles, wherein the carrier gas takes up water vapour from the raw water, g) the raw water that is obtained in step f) that is enriched with the at least one non-volatile component is taken off from the evaporation zone, h) the water vapour- loaded carrier gas from the evaporation zone is fed to the heat exchanger and is cooled in counter current flow to the raw water, wherein the water vapour present in the carrier gas partially condenses out, i) the carrier gas depleted in water vapour is passed out of the heat exchanger, k) the condensed water vapour is taken off from the heat exchanger as pure water, wherein the evaporation zone is operated substantially adiabatically, and wherein the carrier gas is transported by means of natural convection through the evaporation zone and thereafter through the heat exchanger.

    Abstract: Production of alkylaromatic compounds (I), by reacting 3-30C olefins (II) (or alcohols forming (II) under the reaction conditions) with aromatic hydrocarbons (III) in presence of an alkylation catalyst (IV), is carried out in a cascade of at least two reactors each containing (IV), where at least 80 % of (III) is supplied to the first reactor of the cascade and at least 40 % of (II) is supplied after the first reactor. An independent claim is included for the preparation of alkylarylsulfonates (A), by: (1) converting a 4C olefin mixture over a metathesis catalyst to give an olefin mixture containing 2-pentene and/or 2-hexene; (2) catalytically dimerizing the 2-pentene and/or 2-hexene (optionally after isolation) to give a mixture containing 10-12C olefins, optionally separating the 10-12C olefins and separating 5-30 wt. % (based on the 10-12C olefins) of low-boiling components of the 10-12C olefins; (3) reacting the obtained 10-12C olefin mixture with (III) in presence of (IV) to give alkylaromatic compounds (I'), optionally with addition of 0-60 wt. % (based on the 10-12C olefin mixture) of linear olefins before the reaction; (4) sulfonating (I') and neutralizing to give (A), optionally with addition of 0-60 wt. % (based on (I')) of linear alkylbenzenes (provided that no mixing has been carried out in the previous step); and (5) optionally mixing the obtained (A) with optionally with addition of 0-60 wt. % (based on (A)) of linear aralkylsulfonates (provided that no mixing has been carried out either of the previous two steps); The novel feature being that the reaction in the alkylation stage (3) is carried out as for the present procedure for preparing (I).

    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.
