Abstract:
    Process for recovering and moving refinery tar by the formation of oil in water dispersions of the above tar, the above dispersions having a water content of at least 20% by weight, and the dispersing agent being selected from salts of alkaline metals and ammonium, and relative mixtures, of the condensates of naphthalenesulfonic acid with formaldehyde, which comprises: a) fluidification of the tar by heating to a temperature at least equal to its softening point; b) mixing the tar thus fluidified with the desired quantity of water and dispersing agent until an oil in water dispersion is formed; c)recovery and moving of the tar in the form of the oil in water dispersion formed in step(b).
