Patent DE-4311717-C1 (DE)
Title: Distillation esp. of crude oil in pre- and main columns - includes using temp.-matched side stream feed to reduce external heating energy requirements
Inventor: SEIFERT UTE
IPC: C10G7/00
Filed: 1993-04-08
Granted: 1994-06-16
Abstract: In distillation of complex mixts. (esp. atmos. distillation of crude oil), the main column is preceded by one or more pre-columns, the bottom product of the last pre-column is fed to the main column via a radiant preheater, and the initial mixt. is preheated, before and between the pre-columns, only by the waste heat of the product and/or the energy extracted from the circulating return flows of the main column. The novelty is that side-streams are withdrawn from one or more pre-columns and fed to the main column below fittings at which the boiling conditions and temps. of the liqs. flowing from the fittings and of the side-streams are as close as possible. USE/ADVANTAGE - Esp. for atmos. distillation of crude oil, but also for distillation of products from hydrocracking and fluid catalytic cracking. The quantity of last pre-column bottom prod., to be preheated in the radiant preheater, is reduced so that the external energy requirements are reduced, e.g. to 6kJ/kg. product (using one pre-column) or 20 kJ/kg. product (using two pre-columns).

Title: Cellulose acetate filter tow, production thereof and use thereof as tobacco smoke filter element
Inventor: WILLMUND ROLF DIPL BIOL DR
IPC: A24D3/10
Filed: 1993-07-09
Granted: 1994-10-13
Abstract: Described is a filter tow of cellulose acetate filaments and/or fibres on whose surface is present an additive composed of enzymes which cleave cellulose chains, at least the surface of the filaments and fibres consisting of a cellulose acetate having an acetyl number of less than 53%, preferably less than 49%. The process for producing such a filter tow comprises spinning cellulose acetate filaments from a solution of cellulose acetate having an acetyl number of at least 53% in acetone, optionally cutting the filaments into fibres, collecting the filaments and/or fibres together into a filter tow and applying an additive, the filaments and fibres being hydrolysed and the additive applied being one composed of enzymes which cleave cellulose chains. Also described are a tobacco smoke filter element composed of such a filter tow and a process for its production. The filter tow and the tobacco smoke filter element show improved biodegradation under the action of environmental influences, but without danger of degrading in the course of storage under conditions customary today.

Title: Method and device for production of black caviar imitation from food products
Inventor: POPOV FILIPP P
IPC: A23L17/30
Filed: 1990-05-29
Granted: 1995-02-27
Abstract: FIELD: food industry. SUBSTANCE: method involves supply of source solution, in the process of formation of grains, into liquid that is in the state of uniform rotation. The solution is supplied through one or several holes. The holes are 3-5 mm in diameter. The grains are transported by gravity through valves, and the processes of cooling and separation of the grains from the liquid are concurrent with the process of drain of the grain-and-oil mixture into a vessel with cooled water. The water in the vessel is also stirred to rotate. The device for implementation of this method has a vessel divided into two parts: the upper part for formation of caviar grains and the lower part. The latter cools the grains and separates them from oil. Both are provided with electric-driven stirrers. The stirrers are vanes mounted in the center of each vat for rotation. They are also provided with transport valves, and the lower one is provide with a valve for drain of oil. The valve is mounted level with the "forming liquid-water", and the vat for the source solution is an open funnel with one or several outlets 3-5 mm in diameter. They provide communication between the funnel and vat. The funnel has several isolated compartments, and one of them is used for filling. EFFECT: simpler method; higher rate of process. 7 cl, 1 dwg, 1 tbl
