Abstract: A process is disclosed for treating aqueous flushing solutions from zinc phosphatization processes of metallic surfaces. The solutions containing heavy metal ions are contacted with solid, strongly acid cation exchanger resins containing sulphonic acid groups, and the heavy metal ions are then re-extracted from the loaded exchanger resins by means of dilute, aqueous nitric acid or of a dilute, aqueous mixture of nitric acid/phosphoric acid. The eluate from the regeneration is preferably returned to the phosphatization bath.

Abstract: The invention concerns a method of cleaning objects contaminated with fresh paint and/or varnish, using a hot paint-removal agent. In order to be able to regenerate the paint-removal bath economically, without significantly reducing the proportion of active substances it contains, the invention proposes that the aqueous paint-removal bath is regenerated by microfiltration. The bath liquor is passed, without significant cooling, across a ceramic membrane at a given minimum flow rate and a given minimum cross-membrane pressure difference. The material retained by the membrane is discarded.

Abstract: In a process for carrying out an equilibrium reaction, one or more products are removed by vapour permeation. To obtain high reaction rates at high reaction temperatures, the reaction is carried out in a bubble reactor (1) and the lower boiling point educt is passed through the educt maintained at the reaction temperature in the reactor. The reaction temperature and reactor pressure are adjusted so that the reaction temperature is above the boiling point of at least one of the products, the vapour permeation takes place outside the reactor (1) at a suitable temperature dependent on the membrane material, and the vapour phase (10) of the reaction mixture in the reactor (1) is supplied as feed to the membrane module (2) in which the vapour permeation is carried out.

Abstract: The invention concerns a discontinuous process for conducting a heterogeneously catalysed reaction which takes place at high temperatures and which yields heat-sensitive products. Heating is effected by a heat-exchanger (4) distinct from the reactor (1) and the catalyst used is a fixed bed catalyst (3). The reaction mixture is circulated continuously through the catalyst (3) and the heat-exchanger (4) in succession. The aim is to prevent losses of catalyst and product and to achieve a reduction in charge and reaction time according to the German Patent Applications P 38 13 612.0 and P 38 26 320.3. The invention also concerns an installation for discontinuous heterogeneously catalysed manufacture of heat-sensitive products at high temperatures with a reactor which possesses an external heat-exchanger (4) connected to the reactor (1), an upstream catalyst container (3) with a fixed bed catalyst and a pump (2) which circulates the reaction mixture continuously through the catalyst (3) and the heat-exchanger (4) in succession.

Abstract: In the process proposed, the raw oil or fat is mixed at elevated temperature with acid and water and allowed to react so that the impurities pass into the aqueous phase. The mixture is then separated into purified oil and acid water. The acid water is concentrated by ultrafiltration and the permeate fed back to the initial stage of the process in which the raw oil or fat is mixed with acid and water. The oil and fat constituents emulsified with the aqueous phase are thus recovered and the quantity of waste water produced is considerably reduced.

Abstract: In the method proposed, the exhaust gases arising from the drying of products containing volatile constituents are cooled, the condensate thus obtained is subjected to cross-flow membrane filtration and part of the purified exhaust gases fed back to the drying process. The concentrate obtained is recycled in such a way that the substances in it can be re-used, to produce thermal energy, or in some other way. The effective and economic method is suitable for use in disposing of aerosols, in particular organic aerosols, in the exhaust gases.

Abstract: A process is disclosed for removing cellulose ether and other cellulose derivates from an aqueous solution/suspension. An effective and economical process that allows a considerably higher amount of cellulose derivate to be recovered from the wash water as in the state of the art, is characterized in that the flocculated cellulose derivates are removed in a first step from the solution heated over the flocculation point, the solution is subjected in a second step to a membrane filtration, after cooling down below the flocculation point, and the concentrate thus obtained is heated over the flocculation point and further concentrated.
