Abstract: PCT No. PCT/FI92/00193 Sec. 371 Date Nov. 2, 1992 Sec. 102(e) Date Nov. 2, 1992 PCT Filed Jun. 18, 1992 PCT Pub. No. WO92/22353 PCT Pub. Date Dec. 23, 1992The object of the invention is to provide a new method and a new equipment for extinguishing fires especially in engine rooms and similar spaces. The fire is extinguished or at least pressed down by means of concentrated fog sprays with strong penetrating power, by utilizing high operating pressure, which is gradually decreased for the provision of spread fog-like liquid spraying. The extinguishing liquid is preferably delivered to spray heads (43, 44, 45) by using hydraulic accumulators (41, 41a).

Title: Process and installation for producing high purity esters of fatty acids
Inventor: OPRESCU ION
IPC: C07C69/00
Filed: 2002-07-04
Abstract: The present invention relates to a process and an installation for producing high purity esters of the fatty acids, used as solvents, plastifiers, additives for fuels, fuels for Diesel engines etc., they being non-toxic and biodegradable. According to the invention, the process for the transesterification of the natural raw or refined fats, simple or in admixture and with esters of the fatty acids as cosolvent; where the mixing, homogenizing and heating the reaction mass is performed by recycling in an exterior circuit through a special ejector, the alcohol excess being recovered by distillation from the transesterification reactor, the raw ester separation being carried out by decantation, the separated raw ester neutralization being performed by contacting, in counterstream, with acidified water in an extractor equipped with a special structured sheet metal filling, the neutralized ester high purification operation being performed by the subsequent recycling, in counterstream with clean water, in the same extractor. According to the invention, the installation consists of a reactor (1) for preparing the reactant, a transesterification reactor (2), a pump (3) for recycling the reaction mass through of a heat exchanger (4) and an ejector (5), a condenser (6) for the excess alcohol vapours, a raw ester decanting vessel (7), a pump for evacuating the aqueous phase and for recycling the organic phase through an extractor (9), a centrifuge (10) for separating the water and the solids from the purified esters.
