Abstract:
Disclosed herein is an apparatus for continuously producing and pelletizing gas hydrates. The apparatus includes a gas supply unit, a water supply unit and a reactor. Gas and water are respectively supplied from the gas supply unit and the water supply unit into the reactor. The gas and water react with each other in the reactor. The reactor includes a dual cylinder unit which forms a gas hydrate in such a way as to squeeze a slurry of reaction water formed by the reaction between the gas and water. The dual cylinder unit includes an upper cylinder, a lower cylinder and a connection pipe which connects the upper cylinder to the lower cylinder. The connection pipe has passing holes through which the reaction water in the reactor flows into and out of the connection pipe.

PURPOSE: A pump connection structure of a natural gas supply system for offshore structures is provided to freely arrange a pump on an offshore structure by easily arranging the pump and a transfer pipe for supplying natural gas to the pump with a flexible hose. CONSTITUTION: A pump connection structure of a natural gas supply system for offshore structures comprises a transfer pipe, a pump, and a flexible hose. The transfer pipe is a path for transferring LNG from an LNG storage tank(101) to a high pressure gas jetting engine. The pump presses and discharges the LNG to make the LNG transfer through the transfer pipe. The flexible hose is arranged between the transfer pipe and the pump.
Abstract:
A method includes providing a length of pipeline that has a housing defining a central bore extending the length of the pipe and a space formed within the housing and extending the length of the pipe. At least one condition within the space is continuously monitored within the space to detect in real time if a change in the housing occurs.
Abstract:
The present disclosure provides a method for smart gas pipeline frost heave safety management and an Internet of Things system. The method includes: obtaining gas transmission data and gas pipeline data and determining gas pressure change data of a target point based on the gas transmission data and gas pipeline data; predicting temperature change data of the target point based on the gas pressure change data, the temperature change data including gas temperature change data and soil temperature change data; predicting, based on the temperature change data, the gas pipeline data, and the gas pressure change data, and in combination with environmental data, a frost heave degree data of the target point; and determining, based on the frost heave degree data of the target point, the gas transmission adjustment data and a frost heave prevention plan.
Abstract:
A method and system for restoring flow capacity to a submerged fluid conduit comprising a laser light apparatus to generate blue laser light to be impinged on the fluid conduit. The method and system include a frequency multiplier (15) for converting infrared laser light from a laser light generator (14) to blue laser light having a higher transmissivity in seawater. The frequency multiplier may be disposed on a submergible vehicle (2). In one embodiment, a non-submerged infrared laser light generator (14) supplies, via optical conduits (21), laser light to a submerged frequency multiplier (15) on the vehicle (2). Blue laser light, at a wavelength in the range of 440-500 nm, is emitted through an optical window and through seawater to impinge on the surface of the fluid conduit.
Abstract:
The present invention relates to a method for reducing gas hydrate adhesion to the interior surface of a conduit and associated equipment transporting or processing a fluid stream in oil and gas exploration and production, petroleum refining and/or petrochemistry, by providing the conduit interior surface with a coating layer exhibiting a static contact angle of the sessile water drop on the coating layer in air higher than 75° at ambient air conditions, as measured according to ASTM D7334-08, wherein said coating layer comprises diamond like carbon (DLC) comprising fractions of one or more components selected from the group consisting of silicon (Si), oxygen (O) and fluor (F).
