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.

The present invention relates to a device for liquid degassing by means of swirling or centrifugal force coupled with a pressure gradient. This device comprises a cavity. The cavity is furnished with an inlet for liquid-gas mixture, a gas outlet and a liquid outlet. The gas outlet is inserted into the cavity through the top end of the cavity and positioned around 0.1-3 times the maximum diameter of the cavity from the top of the cavity. Specifically, an overflow pipe with the diameter gradually increasing from the bottom to the top was used as the gas outlet. The overflow pipe is further furnished with a bell mouth at the bottom part.

This disclosure provides a two-phase separator device for separating condensate or particulate from a gas stream. In some implementations, the separator device removes water from air and may operate under micro-gravity conditions. The gas stream flows through the two-phase separator device and passes through a rotatable vane assembly along a flow path without being redirected in another flow path. Condensate or particulate in the gas stream is impacted by a plurality of vanes of the rotatable vane assembly, and the condensate is captured by features formed within the plurality of vanes. The captured condensate is accelerated radially outwardly along the each of the plurality of vanes towards a sloped inner wall, and further moved along the sloped inner wall in a direction against the flow path of the gas stream during rotation.

An at least two shaft reactor/mixer, in particular for process engineering treatment of highly viscose, elastic and/or solid containing reaction substance and mixture, in which at the housing inner wall inwardly directed static mixing elements are arranged, which interact with scrapers of the at least two shafts in such a way, that in the area of the spaces between the scrapers the static mixing elements and the housing inner wall sheer forces, in particular a flow disturbance, are generated in an enhanced manner. In addition, there is a system including an end cap for a one or multiple shaft reactor/mixer and a discharge screw connector block being connectable with the end cap in a detachable manner.

An apparatus for filtration has a feed of sludge, containing liquid, solids and gases fed into a tank, the tank containing at least one spinning separation filter comprising a filter cone set having a filter screen, and a barrier cone, arranged roughly in parallel, and defining a conical workspace between them, the conical workspace having a peripheral opening to the tank and a central opening communicating with the interiors of one or more hollow shafts supporting the barrier cone and the filter cone, the upper shaft supporting the barrier cone having an upper axial channel for the exit of gases, the lower shaft supporting the center of the filter cone having a lower axial channel for the exit of liquid or oil, motor means for producing rotation in said at least one spinning separation filter, and a filtrate liquid reservoir located underneath the filter cone for capturing the filtrate passing through the filter screen.

An apparatus for degassing of gaseous components from at least one curable material, particularly a curable material for building a composite part, for example, a rotor blade for a wind turbine, is provided in an embodiment herein. The apparatus includes at least one degassing chamber having at least one inlet for introducing a curable material for building a composite part, the curable material containing gaseous components into the degassing chamber and at least one outlet for removing a degassed curable material from the degassing chamber and at least one mechanical splitting means adapted to mechanically split up gaseous components contained within the curable material so as to release the gaseous components from the curable material.

The present invention is a single oilfield treatment vessel for removing water, solids and gas from crude oil. The vessel functions to replace three separate normally used vessels: a gas separator, a free water knockout vessel and a heater treater. The present vessel functions more efficiently than the three vessels it replaces by virtue of its superior internals and efficiency based design. It pays for itself more quickly by increasing the quality and value of the effluent fluids and by reducing installation and operating costs.

An assembly is provided for a turbine engine. This assembly includes a static structure and an impeller rotor housed within the static structure. The impeller rotor includes a vane structure and a shroud. The vane structure includes a first sidewall, a second sidewall and a plurality of vanes arranged circumferentially about a rotational axis. The vanes include a first vane. The first vane includes a first portion, a second portion and a third portion. The first portion is axially between the first sidewall and the second sidewall. The second portion is radially between the first sidewall and the shroud. The third portion is radially between the second sidewall and the shroud. The shroud circumscribes the vane structure. A gap is formed by and extends between the shroud and the static structure. A dimension of the gap changes as the gap extends along the shroud.

The present invention provides a gas-liquid separator with enhanced performance and easy operation, capable of performing gas-liquid separation such as advanced defoaming or degassing, and with a structure that facilitates easy CIP cleaning and disassembly cleaning, allowing it to meet sanitary specifications.

This gas-liquid separator for gas-liquid separation performed by centrifugal force of an impeller mounted on a shaft which is supported by a bearing part and rotates in a casing comprises: the axial end of the impeller farther from the bearing part being positioned with clearance from the inner wall of the casing so as to slide on the inner wall of the casing; an exhaust outlet of the casing disposed in a position opposite the sliding impeller part; a vacuum device connected to the exhaust outlet; a discharge impeller part providing discharge force to the passing fluid formed around the axial end of the impeller; a discharge outlet of the casing disposed in a position opposite the discharge impeller part; and a suction inlet of the casing disposed in a position closer to the bearing part than the discharge outlet.

A bubble removing system and a bubble removing method are provided. The bubble removing system comprises a main bubble removing apparatus which comprises a first enclosed container, a first fluid lead-in pipe, a first fluid lead-out pipe, and a bubble collecting member. The cross section of the inner cavity of the first enclosed container is circular, and the first enclosed container is used for accommodating a fluid substance. The first fluid lead-in pipe passes through a sidewall of the first enclosed container, is tangent to the inner cavity wall of the first enclosed container, and is disposed at the upper part of the first enclosed container. The first fluid lead-out pipe passes through the sidewall of the first enclosed container and is disposed at the lower part of the first enclosed container.
