    摘要: The invention relates to an oxycombustion method with capture of the CO2 produced. Mixer M supplies chamber CC with a mixture of oxygen from unit O and of recycled fumes from storage drum SG. Chamber CC is supplied with oxidizer from mixer M and with fuel flowing in through line 8. All of the combustion fumes are sent to water condensation unit CT, then fed into storage drum SG. Part of the fumes containing all the CO2 produced by combustion is compressed to about 60 bars, then cooled and partly liquefied to about 15° C. in liquefaction unit L1, and stored in drum SM. According to the invention, the partly liquefied CO2 is compressed by means of a multiphase pump in order to be discharged through line 16 and stored in an underground reservoir.

    摘要: A process and reactor are disclosed for the thermal cracking of a charge containing at least one hydrocarbon with at least one carbon atom, in which the charge is circulated in a metal reaction zone which includes a pyrolysis zone whose external wall is in thermal exchange relationship with a heating liquid. The reaction zone consists of an alloy containing, by weight, 66-82% nickel, 14-18% chromium, and 4-6% aluminum. This alloy, which has already been preoxidized, may be covered, at least in the reaction zone, with at least one layer formed by an oxide of at least one metal and/or at least one metal carbide and/or at least one metal nitride and/or at least one metal silicide. The invention finds application for vapor-phase cracking and dehydrogenation of hydrocarbon charges.

    摘要: The invention relates to a method of isomerising a charge comprising hydrocarbons containing between 5 and 8 carbon atoms per molecule. According to the invention, said charge is separated into at least two fractions: fraction A mostly comprising hydrocarbons containing 5 or 6 carbon atoms and fraction B mostly comprising hydrocarbons containing 7 or 8 carbon atoms. Subsequently, said fractions A and B are treated separately under specific conditions in different isomerisation reaction zones.

    摘要: The fumes flowing in through line 1 are contacted in column C1 with a solvent, at low vapour pressure, absorbing the carbon dioxide. The solvent laden with carbon dioxide is regenerated by distillation in column C2. In order to improve the regeneration operation, a gas is injected through line 11 into column C2 so that this gas carries along the carbon dioxide contained in the solvent. The carbon dioxide-rich gaseous effluent obtained at the top of column C2 can be liquefied by compression and cooling, then stored in surge tank R, which allows its transportation and possibly underground sequestration.

    摘要: A process for the production of an isomerate with a RON that is at least equal to 80 and that contains less than 1% by weight of aromatic compounds, starting with a fraction consisting mostly of hydrocarbons with 7 carbon atoms, and containing paraffins, naphthenes, and aromatic compounds in any proportion is described. Said process uses at least one isomerization unit, at least one unit for opening naphthene rings, and at least one separation unit; these units are combined in such a way as to recycle, to exhaustion, methyl cyclohexane, toluene, and normal paraffins and monobranched paraffins.
