摘要： The invention relates to a device for processing, especially for filtering and removing, fluids and fluid remnants in a low-pressure chamber (1). The device comprises a vacuum pump (30) and a separator (16), whereby the low-pressure chamber is connected to the separator via a first line (10), and the low-pressure chamber is connected to the vacuum pump via a second line (20) so that the low-pressure chamber can be evacuated while bypassing the separator. The invention also relates to a low-pressure chamber for processing fluids which is equipped with a heating plate with holes for heating areas of the interior space of the low-pressure chamber.

摘要： A process for the preparation of concentrated solutions or suspensions of anionic organic compounds is described, which process comprises a) acidifying an aqueous solution or dispersion of an anionic organic compound that comprises salts and/or impurities to a pH of 4.5 or less, if the pH is above that value, so that the anionic organic compound becomes insoluble in water and precipitates out in the form of the free acid, b) bringing the suspension obtained from the previous step to a salt content below 2% by weight, based on the total weight of retentate, by means of ultra-filtration with a ceramic membrane or an acid-resistant organic membrane having a pore size of from 1 to 20 nm, and c) optionally washing out of the salts with water at a pH of less than 4.5, d) optionally carrying out acid-free washing with water thereafter, and then e) concentrating so that the content of anionic organic compound is from 5 to 50 % by weight, and f) optionally bringing the anionic organic compound into solution by adding a suitable base.

摘要： A process for separation of an oil-containing aqueous emulsion includes mixing the oil-containing aqueous emulsion with carbon-dioxide and subjecting the emulsion and carbon dioxide for a specified time within an autoclave to an elevated pressure and an elevated temperature. A rising stream of bubbles is formed within the autoclave by suddenly relieving the pressure within the autoclave with the rising stream of bubbles serving to separate the oil-containing aqueous emulsion into an oil-rich phase and an oil-depleted emulsion. The oil depleted emulsion is transferred to a segrating tank. At least a fraction of the oil-depleted emulsion within the segregated tank is subjected to ultrafiltration to separate the fraction into a permeate and a retentate.
