A bulk adhesive transfer system for transferring adhesive particulate to a melter includes a bulk supply and a transfer device, which may define a hopper of the melter, a mobile bin, and/or a buffer unit. The transfer device is configured to receive unmelted adhesive particulate from the bulk supply and then be selectively docked with the melter to transfer the adhesive particulate to the melter. The bulk adhesive transfer system may also include a knife gate valve device, which includes a plurality of ports that sequentially open and close to control flow of the adhesive particulate towards the melter. The bulk adhesive transfer system simplifies refilling operations for a melter while enabling continuous operation of the melter, even when the transfer device is undocked for removal from the melter.

A method for the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead, the multi-phase production fluid comprising a water phase, an oil phase and a gas phase. The method includes introducing the multi-phase production fluid into a pipeline, the pipeline extending from proximate the wellhead to a point remote from the wellhead; imparting rotational motion to the multi-phase production fluid; wherein the rotational motion of the multi-phase production fluid separates the water phase from the oil phase and the gas phase and reduces the pressure drop along the pipeline. A system for the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead and a method for reducing hydrate formation during the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead are also provided.

Automated methods and systems for diverting transmix from a petroleum pipeline are provided to reduce the overall production of transmix on the pipeline, based on pre-defined programmed cut-points associated with the various subtypes of hydrocarbon carried on the pipeline.

The present invention relates to a system and method of inspecting and relieving pressure and fluid from a pipeline in a safe and environmentally friendly manner. An adjustable insert is placed within a flange of the pipeline, where the adjustable insert has a valve stem capable of moving into contact with a valve device to regulate fluid or gas from the pipeline and one or more outlets for relieving pressure or withdrawing fluid from the pipeline. The system and method provided are capable of operating in a closed process without loosening or removing a flange of the pipeline, thereby improving pipeline operator safety.

A method of vaporising liquefied natural gas (LNG) for measurement of its constituent components may include receiving LNG from a main pipeline into a pressurising device. The method may also include via the pressurising device, pressurising a the LNG beyond a critical pressure thereof. The method may further include directing a first portion of the pressurised LNG to a heater. The method may still further include via the heater, heating the first portion of pressurised LNG beyond a critical temperature thereof, and directing the pressurised and heated LNG to a vaporising device. The method may also include via the vaporising device, depressurising the heated LNG to a pressure below the critical pressure so as to vaporise the LNG.

A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.
