    摘要: In a deasphalting process wherein the deasphalted oil is separated from the deasphalting solvent, the invention consists of performing said separation in at least two separate steps, differing by their temperatures, and of recovering heat from the deasphalted oil.The oil to be deasphalted (26) passes through an extractor (1), then through heat recuperators (3) and (4). The oil-solvent separation is achieved in two steps (5) and (11), under supercritical conditions, at different temperatures. The process has the particular advantage of saving power since external heat is provided (10) to only part of the charge.

    摘要: A continuous process is provided for the preparation of a maleamic acid of the formula: ##STR1## in which: R represents a linear or branched alkylene, arylene, aralkylene, alkylarylene or cycloalkylene radical or a divalent heterocyclic radical, the free valencies of which are attached to carbon atoms, the radical containing 2 to 20 carbon atoms and X represents either a hydrogen atom or the radical: ##STR2## which comprises passing a solution of a primary monoamine or diamine and a solution of maleic anhydride in amounts such that there is a 5 to 20 mol % excess of anhydride, at a temperature of from 40.degree. to 130.degree. C and at a rate greater than 7 m/second through an injection nozzle into a twin screw reactor, the solvent for the primary amine being the same as, or compatible with, the solvent for the maleic anhydride. This process eliminates clogging problems.
