摘要： A method of controlling occurrence of slugging in a riser of a pipeline arrangement including a riser base and pipeline conveying a multiphase fluid system in which the gas phase may be natural gas. The upper end of riser is connected to a separator vessel. The gas phase of the multiphase fluid system is separated from the liquid phase so that the separated gas leaves through gas outlet pipe controlled by a first valve, and the liquid leaves through an outlet pipe controlled by a first valve. The first valve regulates the velocity of gas along the pipeline towards the riser. A pressure sensor observes the gas pressure in the riser base, and if the observed pressure exceeds a predetermined control pressure value a three term pressure indication control causes the first valve to be operated to pen to an extent that increases the gas outflow through the pipe, and thus increases the velocity of gas in the pipeline to avoid occurrence of severe slugging in the riser. The observation of the predetermined control pressure value is deemed to signify incipient slugging.

摘要翻译： 控制在管道装置的提升管中发生堵塞的方法，该管道装置包括提升管基底和输送多相流体系统的管道，其中气相可以是天然气。 提升管的上端连接到分离器。 多相流体系统的气相与液相分离，使得分离的气体离开通过由第一阀控制的气体出口管，并且液体通过由第一阀控制的出口管。 第一个阀门调节沿着管道朝向立管的气体速度。 压力传感器观察到提升管基座中的气体压力，并且如果观察到的压力超过预定的控制压力值，则三项式压力指示控制使得第一阀被操作以增加通过管道的气体流出的程度， 从而增加了管道中气体的速度，以避免在提升管中发生严重的堵塞。 对预定的控制压力值的观察被认为是表示初期的堵塞。

摘要： A gas/liquid separation system includes a cyclone case, a gas outflow pipe including a flange, and a housing that accommodates a valve and is welded to a peripheral edge portion of an upper opening of the cyclone case. An upper opening of a cylindrical portion of the cyclone case is blocked off by the flange of the gas outflow pipe. An annular projection is formed at the flange and at the housing. The annular projections fit together with an annular recess formed in the upper opening edge portion of the cyclone case. The gas outflow pipe and the housing are welded at the upper opening edge portion of the cyclone case. A sealing property can be secured without using seal members, and welding portions are few.

摘要： A filter head and a spin-on fuel filter element where the filter head includes an inlet and an outlet. A threaded nipple extends downwardly from a base of the filter head and includes a central flow passage. A valve member located in the flow passage is normally biased closed. The valve member includes a threaded portion extending outwardly from the nipple. The filter element includes upper and lower end caps, and is located in a housing having a tap plate. The tap plate includes a threaded central opening for screwing the filter element onto the filter head. The upper end cap supports a threaded sleeve which is screwed onto the valve member. The sleeve/valve member combination has a different thread pitch than the tap plate/nipple combination, which moves the valve member to an open position when the filter element is installed on the filter head.
