    摘要: A slug mitigation system for subsea pipelines that includes a riser located between a low subsea level and an upper topside level of a pipeline. There is also a separator located at the top of the riser; and a surface jet pump located at a gas outlet of the separator. In another embodiment of a slug mitigation system, the surface jet pump is located downstream of an in-line separator on a gas outlet using high pressure gas from a downstream process or compressor.

    摘要: A system for improving oil-water separator performance wherein an electrostatic coalescer (15) is located upstream of a cyclonic oil-water separator (16). Preferably, the electrostatic coalescer is able to be bypassed and/or is located in parallel with a mechanical coalescer (17). In the case of parallel arrangement, selection of the flow path route between the electrostatic coalescer (15) and mechanical coalescer (17) is determined by use of an upstream phase detector (18).

    摘要: A system for measuring flow rate in a pipeline by use of a surface jet pump that receives input from both a high pressure pipeline and a low pressure pipeline. Rather than installing flow meters at any or all of the inputs/output from the SJP which is an expensive undertaking, flow rate is predicted by utilising existing pressure sensors located on the high pressure pipeline, low pressure pipeline and discharge pipeline respectively. A control processor predicts flow rate based on correlations between flow rate and pressure for a given SJP geometry and, for example, utilises momentum, conservation of mass and continuity equations, balanced against the pressure forces and velocity in the SJP.

    摘要: The apparatus consists of modular stages arranged in series, each stage including a main chamber and a nozzle opening. In practice, a fluid passing through the opening is subject to a pressure drop as it enters a main chamber of a subsequent stage in the series. This multi-stage pressure drop avoids a sharp drop in temperature, as would occur if the total pressure drop was achieved in one stage, that may cause hydrates to form in an oil/gas pipeline.
