    Abstract: A broad aspect of the disclosure relates to a process for hydroprocessing of a hydrocarbonaceous feedstock stream comprising the steps of



    directing said hydrocarbonaceous feedstock stream to contact a material catalytically active in hydroprocessing thus providing a hydroprocessed stream
    separating said hydroprocessed stream in a purified hydrocarbon stream, sour water and a separation off-gas,
    separating said sour water in a purified water stream and sour stream, directing said sour stream as a liquid sour recycle stream either to contact said material catalytically active in hydroprocessing or to be combined with said hydroprocessed stream prior to step b,
    said material catalytically active in hydroprocessing comprising at least one base metal from Group 5, 8, 9 or 10 of the periodic table in sulfided state.




    This has the benefit of minimizing or even avoiding the need for addition of sulfur to keep the catalytically active material in the active sulfided state.

    Abstract: A process for producing synthesis gas, the process comprising the steps of a) reforming a hydrocarbon feed in a reforming section thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O and impurities comprising ammonia;b) shifting the synthesis gas in a shift section comprising one or more shift steps in series to a shifted synthesis gas; c) separating from the shifted synthesis gas a process condensate originating from cooling and optionally washing of the shifted synthesis gas;d) passing the process condensate to a condensate steam stripper, wherein dissolved shift byproducts comprising ammonia, methanol and amines formed during shifting the synthesis gas are stripped out of the process condensate using steam resulting in a stripper steam stream, e) adding a part of the stripper steam stream from the process condensate steam strip-per to the hydrocarbon feed and/or to the synthesis gas downstream the reforming section, up-stream the last shift step, wherein the remaining part of stripper steam is purged.

    IPC: C10G3/00

    Abstract: Process for the conversion of oxygenates to C5+ hydrocarbons boiling in the gasoline boiling range, comprising the steps of continuously a) providing one or more feed streams of one or more oxygenate compounds; b) heating the one or more feed streams to an inlet temperature of one or more downstream conversion reactors; c) introducing the one or more heated feed stream into inlet of the one or more conversion reactors; d) converting in the one or more conversion reactors the one or more heated feed stream in presence of catalyst to a converted oxygenate product comprising C5+ hydrocarbons; e) withdrawing from the one or more conversion reactors the converted oxygenate product; f) determining at outlet of the one or more conversion reactors amount of the one or more unconverted oxygenate compounds in the withdrawn converted oxygenate product; g) separating the converted oxygenate product into a C4− hydrocarbon fraction, a fraction with the C5+ hydrocarbons boiling in the gasoline boiling range and a fraction comprising water and the one or more unconverted oxygenate compounds, wherein the inlet temperature of the one or more feed streams in step b is continuously adjusted to maintain a constant amount of the one or more unconverted oxygenate compounds as determined in step f.

    Abstract: Process for the preparation of dimethyl ether product by catalytic conversion of synthesis gas to dimethyl ether comprising the steps of contacting a stream of synthesis gas comprising carbon dioxide in a dimethyl ether synthesis step in one or more reactors and with one or more catalysts active in the formation of methanol and dehydration of methanol to dimethyl ether and forming a product mixture comprising dimethyl ether, carbon dioxide and unconverted synthesis gas; cooling and separating the product mixture into a first liquid phase comprising dimethyl ether and carbon dioxide being dissolved in the formed dimethyl ether, and into a first gaseous phase comprising unconverted synthesis gas containing carbon monoxide and carbon dioxide; passing the first liquid phase to a scrubbing zone and contacting the phase with a liquid sorbent being effective in absorption of carbon dioxide; and withdrawing a dimethyl ether product being depleted in carbon dioxide from the scrubbing zone.
