Abstract: An integrated, membrane-based process to produce purified water and conversion of salt to high value chemicals from oil and gas well produced water is described. A liquid stream including water and dissolved salt is flowed through pretreatment units and one or more desalination and concentration units which remove at least a portion of the water to form a brine enriched in dissolved salt. The purified high-density brine may be subjected to electrically-enforced salt dissociation techniques to produce chemicals from oil and gas produced water.

Abstract: An apparatus for temporarily blocking fluid flow through a pipe comprises a housing configured to enclose a portion of a pipe and a flow blockage device. The housing includes a first part defining a housing chamber for receiving the pipe, and a second part defining a stowage space adjacent the housing chamber. The flow blockage device is movable through an aperture formed in one side of the pipe to an installed position in the housing chamber. The flow blockage device includes an outer sealing part that is configurable between an unexpanded configuration allowing the flow blockage device to pass through the aperture and allowing fluid flow through the pipe and an expanded configuration configured to block fluid flow through pipe by substantially preventing passage of fluid between outer side surfaces of the flow blockage device and inner surfaces of the pipe.

Abstract: A hose shroud comprises a tube formed from an aramid fabric rolled into a plurality of tubular layers. The hose shroud has a first end fitting at a first end of the tube, and a second end fitting at a second end of the tube.

Abstract: An automated cleaning system according to an exemplary aspect of the present disclosure includes, among other things, an X-Y positioning system configured to position a lance guide relative to an element to be cleaned. The X-Y positioning system is remotely operated. The system further includes a lance in communication with the lance guide, a drive system configured to drive the lance relative to the element to be cleaned, and a reel configured to manage a slack in the lance.

Abstract: A nozzle for use in a high pressure water jetting system is provided including a stationary housing, a rotating shaft, and a central passage within the shaft for communicating high pressure fluid to the nozzle. The shaft may include communication passages to provide fluid from the central passage to a forward fluid pressure chamber defined between an outer peripheral surface of the shaft and the housing. A rear fluid pressure chamber may be defined between the shaft and the housing and a restriction may be defined between the housing and the inlet end of the shaft, the restriction configured to receive fluid from the rear fluid pressure chamber and transport it to a chamber communicating with the atmosphere. The restriction may be formed as an annular gap between the housing and the inlet end of the shaft and configured to decrease in volume when the shaft moves axially forward.

Abstract: A fluid nozzle for use in a high pressure water jetting system includes a housing to be fixed to a source of high pressure water. The housing receives a rotating member and an inner peripheral bore. The rotating member includes a shaft received within the housing, and a nozzle extending outwardly of the housing, the nozzle having openings extending along a direction having a component both forwardly along an axis of rotation of the shaft and the nozzle, and radially outwardly relative to the central axis.
