Abstract: The present invention relates an apparatus for cleaning water, in particular precleaning seawater, including at least one tank for receiving water containing at least one flocculating agent for separating organic and possibly biological constituents contained in the water. The at least one tank includes at least one contact zone K for contacting the water containing the flocculating agent with at least one gas, in particular air, and at least one separation zone S for separating the flocculated organic constituents buoyed up by the gas. At least one gassing unit is arranged in the at least one contact zone K and at least one filtration unit is arranged in the at least one separation zone S. The at least one gas is injected via the at least one gassing unit without using a liquid carrier.

Abstract: The invention relates to a method of removing aromatic hydrocarbons from coke-oven gas. The coke-oven gas is contacted with a wash liquid in a gas scrubber, and aromatic hydrocarbons are separated by absorption from the coke-oven gas. Subsequently the wash liquid enriched with aromatic hydrocarbons is heated, and the aromatic hydrocarbons are stripped from the wash liquid using water vapor. After cooling the wash liquid is finally returned to the gas scrubber. According to the invention biodiesel is used as the wash liquid.

Abstract: The invention discloses a process for the production of monoglycerides by glycerolysis of methyl ester derived from animal or vegetable fat and oils which includes mixing a surplus of 0.1 to 3 moles of glycerols in relation to methyl ester, subjecting the reaction mixture to a reaction temperature between 130 to 160 at a vacuum of 200 to 400 mbar, adding of alkaline catalysts, stopping the reaction by fast cooling of the reaction mixture and the destruction of the alkaline catalyst when the quantity of glycerides has reached a concentration of mono and diglyceride of 40 to 60%, leaving the catalyst in the reaction mixture to catalyse the reaction downstream in a reactor, separating the surplus methyl ester and glycerol by distillation and stopping the reaction by fast cooling of the reaction mixture with reactor and the destruction of the alkaline catalyst when the quantity of glycerides has reached a concentration of 40 to 60% and the ratio of concentrations of mono and diglyceride lies between 3 to 10.

Abstract: Process for the acid-catalyzed hydrolysis of fatty acid glycerides, wherein the process is carried out continuously with the glyceride and the water being moved countercurrent to each other, and apparatus therefor.
