Black powder flowing with hydrocarbons in a hydrocarbon pipeline is converted into a magnetorheological slurry by implementing wet scrubbing in the hydrocarbon pipeline. A flow of the magnetorheological slurry through the hydrocarbon pipeline is controlled.

A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

A separator device for removing particles from suspension in a fluid includes a housing having first and second apertures for ingress and egress of fluid into and out of the housing. A first separator chamber is disposed at one end of the housing. A second separator chamber is disposed at the other end of the housing. A central chamber is disposed between the first and second separator chambers. The first and second separator chambers are apertured for ingress and egress of fluid from the central chamber, and each contains obstruction means to slow the flow of fluid within the chamber.
