According to the invention, the process consists in treating raw materials consisting of scrap iron wastes, iron ore briquettes, scale, sheets baled in a reaction area, in presence of hydrochloric acid solution of 23...25% concentration, wherefrom there results iron chloride of which minimum 10% of the quantity is recycled, and the remaining quantity is chlorinated to ferric chloride, in another reaction area, placed in cascade, at a solution pH value of 1.5 and a ferric chloride : iron chloride ratio of 38...45% : 0.6...0.2%, thereafter the resulting solution is separated with a polyacrylamide solution and, after filtration, there is obtained a solution of ferric chloride of 38...40% concentration. According to the invention, the installation consists of a reactor (R1) placed in cascade with a reactor (R2), a heat exchanger (S7), a settler (D3), a filter (F4), an intermediary vessel (D) and some process pumps (P1, P2, P3 and P4).

Abstract: The invention relates to a device for reducing the viscosity of lube oils upon the start of internal combustion engines at reduced ambient temperatures. According to the invention, the device uses a low-power ultrasound emitter () which reduces the lube oil viscosity upon the start of internal combustion engines at reduced ambient temperatures and a process automation module comprising an electronic control module () which receives information concerning the temperature of the lube oil by means of a thermostat ().
