Abstract

A method for producing hydrocarbons includes subjecting a first feed stream to steam cracking to obtain a first product stream, and subjecting an ethane-containing second feed stream to oxidative dehydrogenation to obtain a second product stream. A portion of the first product stream is subjected to a deethanization or a depropanization separately from the second product to obtain a lighter fraction and a heavier fraction. A demethanization feed stream is formed by combining at least a portion of the lighter fraction and at least a portion of the second product stream and is subjected at least in part to demethanization. Partial oxygen removal is carried out during the formation of the demethanization feed stream. The oxygen removal is carried out downstream of the combining step.

Abstract

A process for producing a hydrogen product where a carbon-containing input, by reforming and water gas shift, is converted into a synthesis gas largely consisting of hydrogen and carbon dioxide, from which a hydrogen fraction and a carbon dioxide fraction are separated, wherein the hydrogen fraction has the composition required for the hydrogen product and the carbon dioxide fraction has a purity which allows delivery thereof as a product or disposal thereof through sequestration. The characterizing feature here is that the synthesis gas consisting largely of hydrogen and carbon dioxide, by means of a first pressure swing adsorber, is fractionated into a carbon dioxide-depleted first PSA high-pressure fraction and a carbon dioxide-enriched first PSA low-pressure fraction, from which, after compression, the carbon dioxide fraction is obtained by cryogenic gas fractionation.

Abstract

The invention relates to a method for obtaining a hydrogen fraction from a mixture of hydrogen, methane and higher hydrocarbons. First, the mixture undergoes a first condensation at -95 °C to -100 °C, in order to obtain a condensed and a non-condensed portion. A second condensation step is carried out at -130 °C to -150 °C. Then, a pressure swing adsorption is carried out to extract pure hydrogen gas and to leave behind a residual gas. The second condensation step uses the residual gas and a portion of the condensed gas from the second condensation. The formation of the second condensation step involves compressing the residual gas and expanding, evaporating and condensing the fed-back condensed portion. In addition, there is a heat exchange between the second condensed feed and the fed-back amount. The invention also relates to a corresponding plant.

Abstract

A method to produce olefins may include at least one cooling step in a thermal energy recovery by supplying a hydrocarbon feed to an outer tube of the thermal energy recovery assembly; heating the hydrocarbon feed in the outer tube of the thermal energy recovery assembly to output a preheated hydrocarbon feed; supplying the preheated hydrocarbon feed to an electrically powered cracking furnace comprising a reaction zone to heat the preheated hydrocarbon feed; cracking the preheated hydrocarbon feed in the reaction zone of the electrically heated cracking furnace using heat generated by electricity to output hot reactor effluent comprising cracked hydrocarbons and olefins; supplying the hot reactor effluent to an inner tube of the thermal energy recovery assembly; cooling the hot reactor effluent in the inner tube of the thermal energy recovery assembly by transferring heat to the hydrocarbon feed; and where the inner tube outside temperature in the thermal energy recovery assembly stays below 720°C and the inner tube inside temperature in the thermal energy recovery assembly remains above 180°C.

Abstract

A method for producing olefins proposed involves heating a reaction feed, operating a conversion reactor, converting the feed within this reactor, extracting a product gas, and then cooling this gas. The process utilizes a thermal energy recovery system equipped with coaxial inner and outer passages and structures to enhance heat transfer between them. The feed and product gas are passed through the outer and inner passages, respectively, to transfer heat efficiently. Additionally, the reactor is fired using preheated oxidator gas over 400 °C and fuel gas. The thermal system is designed to adhere to specific temperature constraints on the inner passage's containment, ensuring operational safety and efficiency. Corresponding is also disclosed herein.
