A method and a system for the time determination of a phase interface level of a multiphase fluid present in a vertical pipe, include placing a distributed optical fiber sensor comprising an optical fiber cable wound in spiral around the pipe and optically coupled to a DAS interrogator, determining, from the data acquired by the DAS interrogator, the power spectral density over a predetermined duration and for each point of a discretized length of the optical fiber cable, integrating the power spectral density over a predefined frequency band for each point of the discretized length of the optical fiber cable, and setting in matrix form the results of the integration of the power spectral density in order to determine at least one interface level of the multiphase fluid.

Method and system for determining over time a level of a phase interface of a multiphase fluid present in a vertical pipe

A facility and a method for processing gas from a subsea gas production field, includes a cooling module supplied with a gas/liquid mixture coming directly from at least one subsea gas field, and a gas/liquid separation module which delivers processed gas to a gas export pipeline and liquid to a liquid export pipeline. The gas/liquid separation module includes a gas/liquid separator and a coalescing filter separator which are connected in series. The gas/liquid separator has a gas outlet connected to an inlet of the coalescing filter separator and a liquid outlet connected to the liquid export pipeline. The coalescing filter separator having a gas outlet connected to the gas export pipeline and a liquid outlet connected to the liquid export pipeline.
