A liquid supply device includes: a storage tank configured to store a processing liquid including a first processing liquid (sulfuric acid) and a second processing liquid (hydrogen peroxide solution); a circulation path having a first pipeline through which the processing liquid passes in a horizontal direction, and configured to circulate the processing liquid stored in the storage tank; a branch path configured to supply the processing liquid to a processing unit; and a branching part having an opening for allowing the processing liquid to flow out from the first pipeline to the branch path, wherein the opening is formed in the branching part and formed below a periphery of the first pipeline when the first pipeline is viewed in section.

A separation apparatus for separating constituents from effluent. The separation apparatus includes a gas diffuser, a hopper, and a tank. The gas diffuser includes an inlet inner tube for receiving effluent from a well. The hopper is disposed at least partially below the gas diffuser, and the tank is connected to the hopper. The gas diffuser is configured so that gas in the effluent is released from the effluent and into the atmosphere before the effluent enters the hopper. The hopper is configured so that liquid effluent in the hopper spills over a top portion of the hopper and into the tank.

A three-stage degassing and dewatering device includes a first-stage degasser, a second-stage degasser, an oil drainer, a rod electrode, a dewaterer, and a water drainer. The first-stage degasser implements a first-stage axial-flow type collision buffer degassing and dewatering operation, forming a first-stage crude oil after removing some of the gas and water in the gas-containing and water-containing crude oil. The second-stage degasser implements a second-stage elevated efficient degassing operation, forming a second-stage crude oil after removing the remaining gas in the first-stage crude oil. The rod electrode constructs a dynamic electric field with a high frequency and a high voltage, and implements a third-stage high-frequency and high-voltage rapid dewatering operation together with the dewaterer, forming a qualified crude oil after removing the remaining water in the crude oil emulsion.

A method and system for separating oil well substances provided with means for capturing liquid in separated gas for preventing liquid carry over in separated gas as well as providing a liquid lock preventing gas carry over.

The object of the present invention is to provide a novel flow analysis method and a novel flow analyzer each of which makes it possible to improve accuracy of an analysis. A flow analysis method in accordance with an embodiment of the present invention attains the above object by including: a sample introducing step of introducing a sample into a tube (100); a reagent adding step of adding a reagent to the sample which is transferred through the tube (100); and an analyzing step of quantitatively or qualitatively analyzing the sample to which the reagent has been added and further including, after the reagent adding step and before the analyzing step, a gas-liquid separating step of sequentially removing gas which is present in the tube (100).

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 and apparatus for separating of gas from liquids in a wellbore, the apparatus enabling the receiving of wellbore fluids into two or more production separation chambers, operating in parallel. The apparatus further enabling the receiving of production separation chamber fluids into a production pipe through a thief jet port disposed in a lower chamber beneath the production separation chambers. The apparatus further enabling extraction of bottom hole gas fluids in the wellbore from under the two or more production separation chambers and disposing the gas fluids back into the wellbore above the two or more production separation chambers.

Devices for separating gas and liquid components from a fluid are used in a wide variety of processes. These devices may be formed of a housing having a cavity, an inlet, an outlet, and a vent. A diversion structure may be located within the cavity of the housing to allow fluid to flow in a convoluted path which promotes separation of the gas and liquid components. The device may be used in semiconductor fabrication processes or any other processes which require gas-free liquids.

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.

Techniques involve cleaning a polymer melt, which allow volatile foreign substances and solid foreign substances to be removed from the polymer melt. Such techniques involve a filter element and a vacuum of a vacuum chamber. The polymer melt is fed through the filter element into the vacuum of the vacuum chamber, The filter element binds the solid foreign substances and the vacuum chamber takes up the volatile foreign substances.
