The invention describes a process for the capture of organometallic impurities in a hydrocarbon feedstock of gasoline type containing olefins and sulfur, in which a capture body is brought into contact with the feedstock to be treated and a stream of hydrogen, said capture body comprises an active phase based on nickel oxide particles with a size of less than or equal to 15 nm, said active phase not comprising other metal elements of Group VIb or Group VIII, which are deposited on a porous support chosen from the group consisting of aluminas, silica, silicas/aluminas, or also titanium or magnesium oxides, used alone or as a mixture with alumina or silica/alumina.

Process for the production of hydrogen with intermediate-pressure purging

The invention concerns a process for desulphurizing a feed comprising oxygen-containing compounds, hydrocarbon-containing compounds and organic sulphur-containing compounds, by capturing sulphur on a capture mass comprising iron oxides or zinc oxides and more than 20% by weight of zinc ferrite. The process is operated in the presence of hydrogen at a temperature in the range 200&#xb0; C. to 400&#xb0; C.

The invention relates to a process for the production of thermally-integrated hydrogen from a liquid hydrocarbon feedstock that contains sulfur-containing compounds that comprise at least one stage for heating the liquid hydrocarbon feedstock by indirect heat exchange with a hot stream, a stage for desulfurizing the heated hydrocarbon feedstock, a stage for evaporating the desulfurized hydrocarbon feedstock by indirect heat exchange with the hot stream that exits from the autothermal reformer, a stage for autothermal reforming of the hydrocarbon feedstock, and a stage wherein the carbon monoxide content in the hydrogen-rich gas that is produced is reduced in a reactor for converting carbon monoxide with water. The invention also relates to the hydrogen production installation that corresponds to this process.

Process for catalytic conversion in the presence of hydrogen with regeneration of the catalyst that comprises a stage for reduction of said catalyst by the hydrogen that is obtained from the catalytic conversion stage, whereby this hydrogen is purified in advance of impurities that it contains by running it over adsorbent masses, whereby said adsorbent masses are regenerated by an increase in temperature that is provided by the effluent from the reduction stage of the catalyst. Application to the processes for regenerative reforming or dehydrogenation of paraffins and naphthenes and most generally to any moving-bed process that operates in the presence of hydrogen.

The raw natural gas is deacidized and dehydrated in units DA and DH. The treated gas is then purified by adsorption of the mercaptans in first enclosure A. Part of the purified gas is heated in E, then fed into second enclosure Aso as to discharge the water adsorbed by the adsorbent material contained in this second enclosure. A steam-rich stream is fed into third enclosure Acontaining a mercaptan-laden adsorbent material. In A, the mercaptans are desorbed and replaced by the steam.

Process for recovering a solvent from a gas coming from a treating process using the solvent, the gas having a low temperature Ta and a high temperature Td, the difference Td-Ta being sufficient to carry out an adsorption step and a desorption step. The process is characterized in that/ a) a first solvent-containing gas stream is sent to an adsorption step, this gas being at a temperature Ta, at the end of this step the gas is practically solvent-free and the solvent is collected in a first adsorber, b) a second gas stream at a temperature Td, this gas being solvent-free, is sent to carry out desorption of a second adsorption means loaded with solvent during a previous step a), and c) the solvent is sent at least partly to a step of the treating process using the solvent.

Process for adsorbing and desorbing a solvent contained in a natural gas from a dehydration process

A process for transporting a fluid in a pipe under conditions where hydrates may form. In the process, the pipe fluid contains at least one of a gaseous hydrocarbon or liquid hydrocarbon and water and the water content is less than the liquid hydrocarbon content. The process includes the steps of 1) adding a dispersive additive in a hydrocarbon solution to the fluid to be transported, so as to form an emulsion, 2) transporting the liquid and gaseous hydrocarbons in the presence of water and the hydrates, 3) separating the gas phase, the hydrocarbon liquid in excess and a liquid hydrocarbon phase comprising the hydrates and the dispersing additive, and 4) separating the liquid hydrocarbon phase comprising the hydrates and the dispersing additives. The liquid hydrocarbon phase comprising the hydrates is separated by dissociating the hydrates to form a water-in-oil emulsion, the additives being solved in the oil or liquid hydrocarbon, and breaking the water-in-oil emulsion so as to obtain an aqueous phase and a liquid hydrocarbon comprising the additives. Finally the liquid hydrocarbon phase containing at least part of the dispersing additive from step 4, is recycled to a point in the pipe.
