This invention relates to a liquid degassing means, and method of operation. The means comprises a tank, the tank having one or more baffle(s) within the body of the tank, with at least one baffle defining a first and second region. The first region houses relatively turbulent conditions compared to the second region. There is a both a gas transfer gap and a liquid transfer gap, allowing the transmission of fluid from the first to second regions. An inlet introduced the mixture to be degassed to an antechamber, with the fluid travelling onwards to the first region, and then through the gas and liquid transfer gaps to the second region. A first outlet allows for the degassed liquid to leave the tank, and a second outlet allows for the purged gas mixture to also leave the tank. Sensors and complementary control units allow for better operation of the unit.

A method for degassing flowable fluids, in particular liquids used for hydrogen storage, uses a device including a desorber (12) that can be filled with fluid to be degassed and through which the fluid can flow. A circulation pump (48) circulates the fluid during a degassing process in the desorber (12). A vacuum pump (38) generates a vacuum in the desorber (12) during a filling step with fluid and for discharging the gas from the desorber (12) during the degassing step. At least one sensor (44a, 44b) measures the pressure in the desorber (12) and/or a dwell time. A control unit ends the degassing process when a predefined pressure is measured by the sensor (44a, 44b) and/or when a predefined dwell time of the fluid in the desorber (12) is measured.

Upstream process equipment transmits a predetermined fluid to downstream process equipment. A valve fluidly couples the upstream process equipment to the downstream process equipment. A first pressure sensor and a first temperature sensor are coupled to the upstream process equipment and upstream from the valve. A second pressure sensor and a second temperature sensor are coupled to the downstream process equipment and downstream from the valve. A control system is coupled to the first pressure sensor, the first temperature sensor, the second pressure sensor, and the second temperature sensor. The control system determines a first fluid flowrate of the predetermined fluid using a fluid flow model based on pressure data from the first pressure sensor and the second pressure sensor, temperature data from the first temperature sensor and the second temperature sensor, a size of the valve, at least one fluid parameter regarding the predetermined fluid, and a valve flow coefficient of the valve.

A system and method for inerting a protected space is disclosed. Process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion of the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the separator to the cathode. Process water is directed through a process water fluid flow path including a gas outlet and a gas discharge valve in operative fluid communication with the gas outlet. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, and the oxygen-depleted air is directed from the cathode of the electrochemical cell along an inerting gas flow path to the protected space.

Degassing device for degassing a liquid flow, including: a housing for receiving liquid from the liquid flow therein, the housing having one or more ports for connecting to the liquid flow; a valve arranged for allowing gas to escape from the housing; and a heater arranged at least partly inside the housing for raising a temperature of the liquid received in the housing with respect to a further temperature of the liquid flow.

A system and method for determining an efficiency of gas extraction. A chamber allows inflow and outflow of the drilling fluid. An amount of gas extracted from a drilling fluid flowing through the chamber at a constant rate during a dynamic process is measured. A dissolution curve is obtained indicative of a gas remaining in the chamber after the dynamic process. An amount drawn from the chamber during a static process subsequent to the dynamic process is measured. An amount of gas from the drilling fluid during the static process is determined from a difference between the amount of gas drawn from the chamber during the static process and an amount of gas indicated by the dissolution curve. The gas extraction efficiency is determined from a ratio of the amount of gas extracted during the static process and the amount of gas extracted during the dynamic process.

Aspects of the present disclosure relate to apparatus and methods for regulating flow from a geological formation, and associated components thereof. In one implementation, an apparatus for regulating a multi-phase fluid stream flowing from a subterranean geological formation includes a conduit. The conduit includes an outer wall, a primary flow path for a fluid stream, and a first restriction having a throat portion. A first return path includes a return channel, and the return channel is fluidly connected to the primary flow path through a return inlet and a return outlet. The apparatus includes a gas siphon port formed in the outer wall of the conduit, and a gas siphon path extending from the conduit. The gas siphon path is fluidly connected to the gas siphon port.

One method disclosed herein of processing a process fluid that comprises dissolved gas includes performing a degassing process on the process fluid by heating the process fluid via heat transfer with a heat transfer fluid, wherein at least some amount of the heat transfer fluid condenses in the first heat transfer process and latent heat of the heat transfer fluid as it condenses is used to increase the temperature of the process fluid. Thereafter, the heat transfer fluid is passed through an expansion device so as to produce a post-expansion heat transfer fluid. The temperature of the heated process fluid is decreased by performing a second heat transfer process between the post-expansion heat transfer fluid and the heated process fluid, wherein the temperature of the post-expansion heat transfer fluid is increased and the latent heat that was supplied to the process fluid in the first heat transfer process is removed.

Provided is a device which is capable of ongoing measurement of variable foaming tendencies in a fluid system and provide a signal to regulate the feed rate of defoamer accordingly to maintain foaming at an acceptable target level. The regulation of feed can be accomplished automatically or manually.
