Multiphase flow meter for subsea applications using hydrate inhibitor measurement

Номер: US20120046870A1
Автор: Babajide Adejuyigbe, John Lievois, VIJAY Ramakrishnan
Принадлежит: Individual

Methods and apparatus for determining phase fractions (relative concentrations) within a multiphase fluid mixture, in the presence of an injected hydrate inhibitor. Combining this phase fraction information with a hydrate inhibitor injection rate (HIIR) enables resolving oil and water flow rates for the phase fractions. The liquid flow rates and a total combined flow rate of the fluid mixture—determined based on a differential pressure of the fluid mixture through a given area—enable resolving a gas flow rate.

Methods of measuring gas flow rates in a gas supply system for supplying gas to a plasma processing chamber are provided. In a differential flow method, a flow controller is operated at different set flow rates, and upstream orifice pressures are measured for the set flow rates at ambient conditions. The measured orifice pressures are referenced to a secondary flow verification method that generates corresponding actual gas flow rates for the different set flow rates. The upstream orifice pressures can be used as a differential comparison for subsequent orifice pressure measurements taken at any temperature condition of the chamber. In an absolute flow method, some parameters of a selected gas and orifice are predetermined, and other parameters of the gas are measured while the gas is being flowed from a flow controller at a set flow rate through an orifice. In this method, any flow controller set point can be flowed at any time and at any chamber condition, such as during plasma processing operations. Gas supply systems are also disclosed. 1.

A gas, whose flow rate is adjusted by a flow rate controller as a measurement target, is supplied into a processing vessel in a state that a third valve of the gas supply system provided at an upstream side of the processing vessel is opened. While the gas is continuously supplied, the third valve is closed after a pressure measurement value of a pressure gauge within a flow rate controller for pressure measurement is stabilized. After the third valve is closed, an output flow rate of the flow rate controller as the measurement target is calculated from a previously known volume of the gas supply system in which the gas supplied through the flow rate controller as the measurement target is collected and a rise rate of the pressure measurement value of the pressure gauge within the flow rate controller for pressure measurement with respect to time.

A method for calibrating a product valve disposed along a flow path in a duct, with a calibration valve in a duct remote from the product valve and having a geometric shape and operational parameters corresponding to those of the product valve. A calibration controller establishes calibration conditions and, in responsive thereto, generates a calibration flow rate (CFM) function by measuring for the calibration valve, a sparse set of flow rates and determining a surface-fit mathematical representation of fluid flow through the calibration valve over applied calibrated flow rates and the measured pressure drops. The CFM Function is transferred to a product blade controller, which in turn, processes the representation of the mathematical surface, and controls fluid flow through product valve based on values extracted from the received CFM Function as well as at least one parameter control signal indicative of a desired set point.

A method of determining an estimated flow rate for at least one phase of a multi-phase fluid flowing from a subsea well; a subsea well; and a system for determining an estimated flow rate for at least one phase of a multi-phase fluid flowing from a subsea well are disclosed. The method of determining an estimated flow rate for at least one phase of a multi-phase fluid flowing from a subsea well comprises determining a mass or volumetric flow rate of a fluid in a completion or production tree of a subsea well; determining a Water Liquid Ratio (WLR) of said a fluid via a water sampling device; determining an upstream fluid pressure and an upstream fluid temperature of said a fluid at a location upstream of a production choke valve in the subsea production tree via at least one pressure sensor lement and at least one temperature sensor element of the subsea production tree; determining a downstream fluid pressure and a downstream fluid temperature of a fluid at a location downstream of the production choke valve via at least one pressure sensor element and at least one temperature sensor element of the subsea production tree; determining a downhole fluid pressure and a downhole fluid temperature of said a fluid via at least one pressure sensor element and at least one temperature sensor element located downhole in the completion; and providing each of the determined mass or volumetric flow rate, water liquid ratio, upstream fluid pressure, upstream fluid temperature, downstream fluid pressure, downstream fluid temperature, downhole fluid pressure and downhole fluid temperature as respective inputs for a statistical estimator unit and, via the statistical estimator unit, determining an estimated flow rate for each of at least one phase of fluid flowing downstream of the choke valve.

A reference volume for use with pressure change flow rate measurement apparatus has an internal structure comprising elements with cross section and length comparable to the cross section and length of adjacent interstitial fluid regions. The reference volume may have one or more heat conduction elements exterior to and in good thermal contact with a corrosion resistant material that defines the internal fluid holding region. 1. A system for reference volume measurements , comprising:a reference volume chamber with an inlet portion and an outlet portion for a fluid through the reference volume chamber;an interior region of the reference volume chamber having a bottom wall, a ceiling wall, a central wall and a side wall, wherein the side wall and the central wall extends from the bottom wall and not conjoined with the ceiling wall, thereby making a gap for fluid movement;an exterior wall of the reference volume chamber enveloped by a heat conduction cover for providing a thermal conduction so that the temperature is affected by ambient effects for the fluid in the reference volume chamber; andthe central wall and the side wall capable of being secured with one or more sensors or programmable logic controllers (PLCs).2. The system for reference volume measurements claim 1 , as described in claim 1 , wherein the one or more sensors is a thermal sensor chosen from a group of Negative Temperature Coefficient (NTC) thermistor claim 1 , Resistance Temperature Detector (RTD) claim 1 , Thermocouple or Semiconductor-based sensors.3. The system for reference volume measurements claim 1 , as described in claim 1 , wherein the one or more sensors is a pressure sensor chosen from a group absolute pressure sensor claim 1 , gauge pressure sensor claim 1 , vacuum pressure sensor claim 1 , differential pressure sensor or sealed pressure sensor.4. The system for reference volume measurements claim 1 , as described in claim 1 , wherein the central wall has a tubular structure and ...

An insertable flow meter assembly includes a flow measuring device configured to be inserted into a flow passage of a receiving structure. The flow measuring device is configured to enable determination of a flow rate of fluid through the flow passage, the flow measuring device is formed as a single continuous structure, and an outer cross-section of at least a portion of the flow measuring device is configured to be substantially the same as an inner cross-section of the flow passage. The insertable flow meter assembly also includes an end cap configured to engage an exterior surface of the receiving structure and to couple to the receiving structure at an end of the flow passage. The end cap is configured to block movement of the flow measuring device out of the end of the flow passage. 1.
