A method of treating a pipeline is performed by selecting a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less that exhibit properties of Brownian motion that facilitate penetration of solid deposits on interior surfaces of a pipeline. A treatment composition comprising the colloidal particle dispersion is introduced into an interior of a pipeline by at least one of (A) introducing a batch amount of the treatment composition in a selected volume into the interior of the pipeline, and (B) continuously introducing the treatment composition at a selected rate into the interior of the interior of the pipeline. The composition is allowed to act upon the surfaces and materials adhering to the surfaces of the interior of the pipeline.

A flow management system includes an expandable device configured for attachment to a wall surface of a conduit and being adjustable between an expanded configuration and a collapsed configuration, an electric actuator in fluid communication with the expandable device, and a control module. The control module is configured to control the electric actuator to flow a current to the expandable device to expand the expandable device for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to the expandable device to collapse the expandable device for opening the channel to a fluid flow within the conduit.

A method of managing a fluid flow within a conduit includes determining a presence of a flow blockage within the conduit, the conduit being equipped with an expandable device, controlling an electric actuator to flow a current to the expandable device to expand the expandable device radially, compacting the flow blockage radially along a length of the expandable device to create a channel adjacent the flow blockage, controlling the electric actuator to terminate a flow of the current to the expandable device to collapse the expandable device radially, and exposing the channel to open the conduit to fluid flow.

A method of managing a fluid flow within a conduit includes determining a presence of a flow blockage within the conduit, the conduit being equipped with an expandable device, controlling a fluidic actuator to deliver an actuation fluid to the expandable device to expand the expandable device radially, compacting the flow blockage radially along a length of the expandable device to create a channel adjacent the flow blockage, controlling the fluidic actuator to withdraw actuation fluid from the expandable device to collapse the expandable device radially, and exposing the channel to open the conduit to fluid flow.

Hydrate remediation systems, apparatuses, and methods of making and using same including at least one pair of electrodes detachably or fixedly attached to a pipeline or flowline in a spaced relationship so that a current may be imposed across a section of the pipeline or flowline between each pair of electrodes resulting in electrical heating of the section for a time sufficient to raise a temperature of a fluid in the section of the pipeline or flowline to a temperature above a dissociation temperature of hydrates formed in the fluid.

Methods and systems for removing a gel from wellbore equipment. An example method includes introducing a cleaning fluid into the wellbore equipment comprising the gel disposed therein or thereon. The cleaning fluid includes a brine having a total dissolved solids concentration of between about 30K ppm to about 300K ppm. The method further includes contacting the gel with the cleaning fluid in the wellbore equipment, and removing the gel and the cleaning fluid from the wellbore equipment.

A cleaning method of a heat sterilization system includes: a step of causing a fluid formed of a cleaning liquid or a rinse liquid to flow through the heat sterilization system; a step of supplying hot water to a second-stage heating unit to heat the second-stage heating unit; and a step of measuring fluid temperatures of the fluid at the fluid inlet and the fluid outlet of the second-stage heating unit, and medium temperatures of the hot water at a medium inlet of the second-stage heating unit and a medium outlet of the second-stage heating unit. An overall heat transfer coefficient (U value) of a heating pipe of the second-stage heating unit is calculated based on the fluid temperatures at the fluid inlet and the fluid outlet of the second-stage heating unit and the medium temperatures at the medium inlet and the medium outlet of the second-stage heating unit.
