Abstract: A monitoring system is for a well stream from a hydrocarbon well with seawater injection. The monitoring system includes a sample receiving system, a sample preparation system, an analyzing system, and a pressure control and measurement system. The monitoring system is connectable to a sample point for receiving a sample of the well stream. The sample receiving system includes a fluid conduit connectable for fluid communication with the sample point, and a separator for separating a water fraction from the sample. The sample preparation system includes a filter for filtering the water fraction. The analyzing system includes an x-ray fluorescence analyzer for measurement of a concentration of at least one of dissolved elements Fe, Ba, Ca, S, Cl, P, Cu, Zn, Pb, Br or scale inhibitor tracers in the sample. The pressure control and measurement system is connected to the sample receiving system or the sample preparation system.

Abstract: A device for removal of a liquid from a gas-liquid mixture, comprising an inner tube with an upstream gas-liquid mixture inlet and a downstream gas outlet, a swirl body arranged within said inner tube, at least one opening in the wall or at the end of the inner tube downstream the swirl body for a recycle flow, and a conduit from the at least one opening in the wall of the inner tube to at least one recycle return opening in the swirl body. The swirl body comprises a hub part and one or more swirling elements connected thereto, the hub part comprises a cylindrical shaped main hub and a downstream end hub, and the at least one recycle return opening is arranged in the end hub. The one or more swirling elements are continuous and directly connected to the main hub and the end hub.

Abstract: A cyclone separator for separating a fluid into a gas phase and a liquid phase. The cyclone separator includes a vertically oriented vessel with a gas phase outlet at an upper end of the vessel and a liquid phase outlet at a lower end of the vessel; at least one tangentially oriented fluid inlet at the upper end below the gas phase outlet of the vessel; a liquid extractor extracting liquid through the liquid phase outlet at a rate which forms a bulk liquid phase at the lower end of the vessel; and a gas extractor extracting gas through the gas phase outlet. The cyclone separator has at least one flow velocity deflector located at a level in proximity to the bulk liquid-gas interphase which changes the vertical velocity component of a liquid film travelling down the internal wall of the vessel to a horizontally oriented velocity component.

Abstract: A method and system for purification of a pressurized gas stream, wherein the method includes in a first absorption step bringing the pressurized gas stream in direct contact with a first absorption solution absorbing at least part of the acidic gases, in the gas stream obtaining a gas liquid mixture; and separating the gas liquid mixture in a partly purified pressurized gas stream and a first rich absorption solution.

Abstract: A multiphase fluid separator comprises coalescer means for increasing droplet size in a liquid having droplets of a first phase carried by a second phase, and fluid collecting means for separating the first and second phases. The coalescer means and the fluid collecting means are configured to have a common liquid level. In another aspect, a multiphase fluid separator comprises a vessel housing a compact electrostatic coalescer, and gas separating means. The gas separating means is configured to separate gas from incoming fluid before the fluid enters the compact electrostatic coalescer.
