IPC: A23K1/10
Filed: 1965-03-18
Abstract: In a process for recovering fat and meat meal from animal raw material, the raw material is boiled by indirect heating and the boiled material is separated into glue water and solids and thereafter fat is separated from the glue water and the solids are dried; glue water freed from fat is supplied to the boiler inlet; and glue water freed from fat is also supplied directly to the step in which the boiled material is separated into solids and glue water, so that the glue water supplied to the latter step is used for washing out the fat from the solids without imposing any additional load on the boiler.

Title: Process for purifying and deaerating the condensate/feed water in the circulation system of a power-generating plant
Inventor: BRAND ANDREAS
IPC: F22D11/00
Filed: 1984-07-13
Abstract: In a process for purifying and deaerating the feed water line in the circulation system of a power-generating plant heated by nuclear power, the following steps are carried out in order to solve acute problems of steam-generator corrosion: (a) when the preheater train is filled, with the steam-generator isolating valve (40) closed, the condensate flows several times via a recirculation line (37, 52, 53) back to the condensate-collecting vessel (6) and to the condensate purification apparatus (9); (b) below the water level (7) in the condensate-collecting vessel (6), a deaerating medium (37,38,39) is introduced into the condensate via spray nozzles, rises in the condensate and forms in the deaerating chamber (44), as result of displacement of the air present in its, a cushion which is conducive to oxygen deaerating; (c) the steam produced during deaerating is precipitated in an additional condenser (48) which is located in the venting line upstream of the vacuum pump (47) and which is subjected to a secondary cooling water; and (d) following the start of steam generation and during the low-load period, subsequent deaerating is carried out by means of steam in the collecting vessel of the condenser. As a result, it is possible to provide purified and deaerated feed water over the entire operating range and to reduce to a minimum the deaerating time before the plant is started.
