A process is provided in which a first hydrocarbon-containing composition is provided where the first hydrocarbon-containing composition comprises hydrocarbons having a boiling range from 25&#xb0; C. to 538&#xb0; C. and from 0.1 wt. % to 5 wt. % sulfur, where at least 40 wt. % of the sulfur is contained in hydrocarbons having a boiling point of less than 343&#xb0; C. where at least 40 wt. % of the sulfur contained in hydrocarbons having a boiling point less than 343&#xb0; C. is contained in benzothiophenic compounds, and the first hydrocarbon-containing compound is hydrotreated to produce a second hydrocarbon-containing compound.

Process for treating a hydrocarbon-containing feed

A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a catalyst to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal to produce a second hydrocarbon-containing product.

The present invention is directed to a method and a system for separating hydrogen or helium from gas having a mixture of gaseous components. A compressible feed stream that contains at least one target compressible component and hydrogen or helium is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which the target component(s) is/are capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the target component is absorbed from a compressible product stream containing the hydrogen or helium. The compressible feed stream may be provided at a stream velocity having a Mach number of at least 0.1.

Separation of industrial gases

The present invention is directed to a method and a system for separating oxygen from air. A compressible air stream that contains oxygen is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which oxygen is capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the oxygen is absorbed from other compressible components of the air stream. The compressible air stream may be provided at a stream velocity having a Mach number of at least 0.1.

Separation of oxygen containing gases

A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen, hydrogen sulfide and a metal-containing catalyst at a temperature of 375&#xb0; C. to 500&#xb0; C. and a pressure of from 6.9 MPa to 27.5 MPa to produce a vapor comprising a first hydrocarbon-containing product, where the hydrogen sulfide is mixed with the feedstock, metal-containing catalyst, and hydrogen at a mole ratio of hydrogen sulfide to hydrogen of at least 1:10. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal at a temperature of 260&#xb0; C.-425&#xb0; C. and a pressure of from 3.4 MPa to 27.5 MPa to produce a second hydrocarbon-containing product.

A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a metal-containing non-acidic catalyst at a temperature of 375&#xb0; C. to 500&#xb0; C. to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal at a temperature of 260&#xb0; C.-425&#xb0; C. to produce a second hydrocarbon-containing product.

The present invention is directed to a method and a system for separating gas components of a combustion gas. A compressible feed stream derived from a combustion gas that contains at least one target compressible component and at least one non-target compressible component is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which the target component(s) is/are capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the target component is absorbed from a compressible product stream containing the non-target compressible component(s). The compressible feed stream may be provided at a stream velocity having a Mach number of at least 0.1.

Separation of gases produced by combustion

The present invention is directed to low emission power plant. A compressible feed stream is provided that is derived from a power production unit, where the compressible feed stream contains at least one target compressible component and at least one non-target compressible component, is mixed in a substantially co-current flow with an incompressible fluid stream comprising an incompressible fluid in which the target component(s) is/are capable of being preferentially absorbed. Rotational velocity is imparted to the mixed streams, separating an incompressible fluid in which at least a portion of the target component is absorbed from a compressible product stream containing the non-target compressible component(s). The compressible feed stream may be provided at a stream velocity having a Mach number of at least 0.1.

Low emission power plant

The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.
