A composition useful in oxidative desulphurization of gaseous hydrocarbons is described. It comprises a CuZnAlO mixed oxide, and an H form of a zeolite. The mixed oxide can contain one or more metal oxide promoters. The H form of the zeolite can be desilicated, and can also contain one or more transition metals.

A process, a system, and an apparatus for separation of an oxygenate from a stream is provided. More specifically, a stream comprising the oxygenate is introduced to a quench tower along with a caustic outlet stream comprising a metal salt. Contact between the oxygenate and the metal salt results in conversion of a portion of the oxygenate into a derivative salt. The derivative salt and unconverted oxygenate are condensed by quenching and substantially removed from the quench tower as an oxygenate outlet stream. The gaseous components of the stream, minus a substantial portion of the oxygenate, are removed from the quench tower as a quench outlet stream.

The present invention describes a process for the simultaneous removal of arsenic and sulphur compounds from hydrocarbon streams of fossil origin, wherein hydrocarbon streams of fossil origin resulting from the retorting process of schist are purified by direct contact with hydrated iron oxide, such as goethite (-FeOOH) in its raw natural form (limonite ore particles).

Hydroprocessing facilities may operate for extended periods of time before detection of mercury in the inlet facilities, as mercury adsorbs onto the metallic pipelines used to transport the hydrocarbon fluids, e.g., gas, produced waters, from the wells to processing facilities (flowlines). Once the pipelines become saturated with mercury, mercury will breakthrough and be detected at the inlet facilities. A mercury management/control scheme is disclosed wherein a chemical treatment step using aqueous sulfidic solution is integrated into a progressive pigging plan to clean the pipeline, managing mercury accumulation in the pipeline for a reduced mercury concentration in the fluid exiting the flowlines.
