Re-cycling of used or contaminated oils, partic. for re-processing lubricants - comprises pumping oil into autoclave reactor, adding clarifier clay and adding water contg. dissolved sulphur based catalyst and filtration aid
Re-cycling of contaminated or used lubricating oils comprises:- -pumping the oil into an autoclave reactor. - adding approx. 15% of a clarifier clay (Fullers earth-montmorillonite or bentonite) and:- adding - 1-2% of water in which s S-based catalyst is dissolved -2% of a filtration aid such on a diatonite. Resultant mass formed is heated to a prim. temps. of 100-150 deg. C for 3 hrs. then to a second temp. of 300-320 deg.C for a supplementary period of 2 hrs. - the temp. varies according to the type of contamination or used oil. Distn. of the prod. at a high temp. is then carried out during which vapour is continually injected at 58.8399 x 10 (power4) to 98.0665 x power (4) Pa (6-10 Kg/cm2). and from time to time a vacuum of 73326 Pa (550 mm of Hg) is applied. The distn. lasts from 3 hrs. approx., until termination of the catalyst treatment and adjustment of the flash point (Fulgor). Thermal treatment follows during which samples are collected for examination to determine whether the prod. is ready to be filtered. After pressure filtration the filtrate is examined to ensure that all C waste prods. have been retained in the filter cake. Second stage is opt. carried out. Prod. from the first stage is treated with 8-10% of clarified clay - 0.4% of catlyst in water and 1% of a filtration aid. Prod. is re-calcined for 2 hrs. during which samples are taken for laboratory examination to adjust the technical specification and distn. is effected in the condition on before. Finally the prodn. is filtered and stored after commercial approval. USE/ADVANTAGE - Economic and ecological, partic. for used motor oils. Method is very easy to execute and the final prod. obtd. meets legal requirement if release into the environment. Process is operated in one (or at most two) stages, contrary to previous processes.
