    摘要： A modified gathering manifold is disclosed, including a sampling header coupled to each of multiple production lines of wells, and a plurality of diverters, each coupled to one of the production lines, upstream of a relief header coupled to each of the plurality of production lines and a production header associated with the manifold and coupled to each of the plurality of production lines. The sampling header receives a production fluid diverted by a diverter in the open position. The manifold also includes a three-phase separator coupled to the sampling header downstream of the plurality of diverters that separates the production fluid into crude oil, water, and gas, and detects a volume flow rate for each. A return header passes the crude oil, the water, and the gas from the three-phase separator into the production header where they are combined into a hydrocarbon fluid flow.

    摘要： The continuous liquid separation is a continuous liquid separating apparatus that separates a first liquid and a second liquid that is immiscible to the first liquid and has a higher specific gravity than the first liquid, and includes: a liquid separating tank configured to contain a liquid, and be supplied with a liquid mixture of the first liquid and the second liquid, and including a first discharge portion on a lower side thereof and a second discharge portion disposed at a position higher than the first discharge portion, a valve configured to open/close the first discharge portion, a first sensor configured to detect a first water level of the liquid mixture contained in the liquid separating tank, the first water level being lower than the second discharge portion, and a second sensor configured to detect a second water level of the liquid mixture contained in the liquid separating tank.

    摘要： A crude oil demulsification system includes a vessel. A cyclonic separator is disposed outside the vessel. The cyclonic separator is configured to receive and separate phases of a multi-phase fluid stream into a gaseous stream and a liquid stream that includes a first liquid phase and a second liquid phase by inducing cyclonic flow. A heat exchanger is fluidically connected to the cyclonic separator. The heat exchanger is disposed outside the vessel, and is configured to receive the liquid stream and to heat the liquid stream by exchanging heat with a heating medium flowed through the heat exchanger. An electrostatic coalescer is fluidically connected to the heat exchanger and is disposed inside the vessel. The electrostatic coalescer is configured to receive the liquid stream heated by the heat exchanger and to demulsify the liquid stream by causing coalescence of liquid droplets of one of the first or second liquid phases.
