    摘要: A control system for use with a pipeline that transports a process fluid. The control system includes a distributed temperature sensing system that records temperature data at a plurality of segments along a pipeline, a heating system that heats the process fluid, and a management system. The management system includes a controller that receives the temperature data from the distributed temperature sensing system and determines a first alarm condition for each segment of the plurality of segments along the pipeline. When the first alarm condition is present in adjacent segments, the controller merges the first alarm condition to create an extended segment first alarm condition encompassing the adjacent segments and displays, via a graphical user interface, a representation of the extended segment first alarm condition.

    摘要: Die Erfindung betrifft ein Verfahren zur Beheizung, Warmhaltung und Wiedererwärmung von wärmeisolierten Pipelines (1) für den Fluidtransport, insbesondere von zähen Erdölen zur Verbesserung der Transportfähigkeit aufgrund verringerter Viskosität, und zur Vermeidung einer Erdölverfestigung bei Unterschreitung des Stockpunkts. Zu diesem Zweck wird die Pipeline mit Heizstationen nach dem Prinzip der Kraft-Wärme-Kopplung ausgestattet. Während die dort erzeugte elektrische Energie zur Versorgung benachbarter Abschnitte des elektrischen Pipeline-Begleitheizsystems dient, wird im Bereich jeder Heizstation die anfallende Wärme auf einen durch die Heizstation geleiteten Seitenstrom (über Absperrung 2) des Transportmediums übertragen, der danach wieder in den Haupt-Transportstrom zurückgeführt wird. Mit einem solchen Kombinationsverfahren werden Gesamt-Wirkungsgrade des beschriebenen Beheizungsverfahren von über 80%, bezogen auf die Heizenergie des eingesetzten Primär-Brennstoffs, z.B. Erdgas, möglich.

    摘要: A heavy oil or bitumen or mixtures of heavy oil and bitumen or mixtures of a dilutant and heavy oil or bitumen is treated to separate components of the feed oil and induce reactions that crack the heavy oil or bitumen into light components. A heated inclined dual tube unit arrangement where feed oil enters the arrangement through the inner tube and which opens partway up the outer tube. Vaporized oil continues to flow up within the outer tube whereas the liquid oil product flows down the annular space between the inner and outer tubes. The vaporized oil is condensed beyond the dual tube arrangement to yield liquid oil products. Heat exchange can be done between the products and the inlet feed oil to improve the energy efficiency of the unit.

    摘要: A method of sealing an annulus between inner and outer pipe sections (18, 12) of a pipe-in-pipe system comprises: positioning a sealing mass (30) in the annulus in contact with the inner and outer pipe sections; deforming the sealing mass, for example by shearing and compression, by effecting relative longitudinal movement between the inner and outer pipe sections; and fixing the inner and outer pipe sections against reverse relative longitudinal movement to maintain deformation of the sealing mass. The inner pipe section and a displaced outer pipe section may be fixed by welding them to respective pipes of an adjoining pipe-in-pipe structure. Opposed ramp surfaces, each being similarly inclined relative to the longitudinal direction, extend into the annulus from respective ones of the pipe sections such that the sealing mass may be compressed between the ramp surfaces.

    摘要: The invention relates to a method and apparatus for controlling the trace heating of a pipe. The material conveyed in the pipe is heated with a heating cable (2) attached to the pipe and the temperature of the pipe (1) is monitored by a temperature sensor (5) attached to the pipe, on the basis of which measurement data is controlled the supply of electricity to the heating cable. The rate of change of the temperature indicated by the temperature sensor (5) is monitored by means of a program-controlled processor (7) and the rate of change is compared with a predetermined reference value. If a fall in the temperature is observed which is more rapid than the predetermined rate of change, or if despite heating with a heating cable the temperature does not increase at least at the predetermined rate of change, this observation is determined as flow taking place in the pipe and the supply of electricity to the heating cable is cut off.

    摘要: Изобретение относится к способу обработки тяжелых нефтесодержащих фракций и высоковязкой нефти для магистральной транспортировки по трубопроводам. Способ включает термический крекинг тяжелых нефтесодержащих фракций при атмосферном давлении и температуре 350-400°C в зоне кавитации, на которое накладывают постоянное электрическом поле напряженностью 0,5-2,0 кВ/см. Продукты парообразной и жидкой фаз термического крекинга смешивают в буферной емкости для магистральной транспортировки. Изобретение позволяет снизить вязкость тяжелых нефтесодержащих фракций без существенных энергетических затрат в режиме низкотемпературного крекинга и упростить технологический процесс подготовки к магистральной транспортировке.
