A method of carrying out direct thermal decomposition of a hydrocarbon compound into carbon and hydrogen comprises: introducing a gaseous feed stream comprising at least one hydrocarbon compound into a reactor; and removing at least hydrogen gas and particulate carbon formed by thermal decomposition from the reactor. The method includes providing in the reactor a layer permeable to the particulate carbon and comprising loose particles other than the particulate carbon in a gas phase and passing the gaseous feed stream through the layer. The loose particles other than the particulate carbon comprise particles comprising a catalyst on a carrier. The method includes removing at least part of the layer from the reactor, separating constituents of the removed part, the constituents including some of the particles comprising a catalyst on a carrier, and returning the separated particles comprising a catalyst on a carrier to the layer.

The present invention discloses a gas hydrate-based particulate/waste gas simultaneous removal system and method. R134a can be used to synthesize particulates/coking waste gases into gas hydrate, which can realize the simultaneous removal of particulates/coking waste gases with no pollution and low energy consumption. The system comprises a waste heat recovery device, a gas hydrate primary dust removal tower, a solid-liquid separation primary tower, a gas hydrate secondary dust removal tower, a solid-liquid separation secondary tower, a gas hydrate decomposition pool, a gas-solid separation tower and a low temperature fractionation device. The present invention can achieve the removal of harmful substances such as heavy metals and coking waste gases while removing particulates. Compared with the current particulate control and waste gas treatment device, the gas hydrate method-based device is greatly simplified and can effectively remove multiple pollutants and realize energy saving and environmental protection.

The disclosure provides a method for separating components of a gas. A feed gas stream is cooled in a first vessel. The feed gas stream includes methane, water, carbon dioxide, and Natural Gas Liquids. The feed gas stream is cooled in a first vessel. A portion of the water condenses to form a primary liquid stream, resulting in a first depleted gas stream, which is cooled in a second vessel. A portion of the NGLs condense to form a secondary liquid stream, resulting in a second depleted gas stream, which is cooled in a condensing exchanger. A first portion of the methane condenses to form a liquid methane stream, resulting in a third depleted gas stream, which is cooled in a third vessel. A portion of the carbon dioxide condenses, desublimates, or condenses and desublimates as a final product stream, also resulting in a fourth depleted gas stream.

In a helium purification process, a stream containing at least 10% of helium, at least 10% of nitrogen in addition to hydrogen and methane is separated to form a helium-enriched stream containing hydrogen, a first stream enriched in nitrogen and in methane and a second stream enriched in nitrogen and in methane, the helium-enriched stream is treated to produce a helium-rich product and a residual gas containing water, the residual gas is treated by adsorption (TSA) to remove the water and the regeneration gas from the adsorption is sent to a combustion unit (O).

A processing facility is provided that includes a feedstock separation system configured to separate a feed stream into a lights stream and a heavies stream, a hydrogen production system configured to produce hydrogen and carbon dioxide from the lights stream, and a carbon dioxide conversion system configured to produce synthetic hydrocarbons or the carbon dioxide. The processing facility also includes a hydroprocessing system configured to process the heavies stream, and a hydroprocessor separation system configured to separate a hydroprocessing system effluent into a separator tops stream and a separator bottoms stream, wherein the separator bottoms stream is fed to the hydrogen production system.
