Patent DE-4030688-A1 (DE)
Inventor: RAEHSE WILFRIED DR
IPC: B01D1/18
Filed: 1990-09-28
Abstract: The description relates to a process for obtaining finely divided solid pourable valuable susbtances or mixtures thereof which are suitable for wetting, washing and/or cleaning agents and/or for use in such agents from their aqueous preparations by spray-drying in a stream of hot gas in the region of normal pressure. In the process of the invention, the stream of hot gas is superheat water vapour and the drying of the particulate substance is interrupted before the substance is endangered by the effects of heat, whereby where necessary the pourablility during storage of the thus partly dried substance is ensured by the admixture of such additives as are capable of bonding limited quantities of water and/or a post-treatment is used to homogenise the residual moisture in the particulate substance and/or the substance is post dried in conditions preserving the valuable substance. The process of the invention is especially suitable for the production of pourable solid tensides, particularly anionic tensides based on natural substances which may also be in admixture with soluble or insoluble organic salts to ensure pourability and/or the apparent weight. A further preferred field of use is the introduction of this process for the production of dried valuable silicate-based substances which may be used especially in textile washing agents, whereby the obtaining of dry zoelite-NaA of washing agent quality is a typical example. With the process of the invention it is finally possible advantageously to obtain ordinary textile washing agent spray dried powders, the temperature-sensitive and/or water-vapour volatile components of which can be added to make the final textile washing agent.

Ethylene is pref. preheated to 100-200 deg.C. and added to the recycling gas which is also heated to 100-200 deg.C.; oxygen at 20-180 deg.C. is added to the HCl stream, also at 20-180 deg.C.; in the upper part of the reaction zone, the concns. of ethylene and CO are kept at 1.5-12 vol.%, that of CO2 at 30-48 vol.% and that of oxygen at 0-1.8 vol.%. USE/ADVANTAGE - Improves the safety of this process and enables less expensive measurement and control equipment to be used; yields of (I) are also increased (98%).
