摘要： The present disclosure is directed toward a system and a method for gas-condensate recovery. A gas-condensate separator is in fluid communication with a production header and an ejector comprising a motive inlet, a suction inlet, and an ejector outlet. The gas-condensate separator comprises an inlet, a gas outlet, and a recovered condensate outlet. The recovered condensate outlet is in fluid communication with the suction inlet of the ejector, and the ejector outlet is in fluid communication with the production header. The method comprises feeding a production fluid from a production header to a gas-condensate separator. The production fluid is separated in the gas-condensate separator. A gas and a recovered condensate are recovered and the recovered condensate is recycled into the production header.

摘要： A venturi-type composite nozzle device for suctioning and removing air pollutants is disclosed. The venturi-type composite nozzle device suctions air pollutants in the vicinity thereof by using negative pressure formed through the venturi principle, and then mixes same with water, jets the mixed water and brings same into contact with the air pollutants again, so as to have a large adsorption ratio of air pollutants in comparison to the amount of water usage, and enables water to be reduced by that amount, and thus has excellent operating performance. To perform such functions, the device employs a venturi-type intake casing, an introducing-spray nozzle, and an impeller.

摘要： A mixing device for mixing first and second substances to form a mixed substance includes a housing having first and second inlets for first and second substances and an outlet for the mixed substance. A flow channel between the first inlet and the outlet and has a flow axis therebetween. The flow channel has a Venturi section having a side wall. A lateral feed opening in the side wall in a first lateral direction is connected to the second inlet, and the opening has a feed axis in said first lateral direction substantially perpendicular to the flow axis of the flow channel. Upstream from the lateral feed opening the side wall of the Venturi tube section forms a first constricted part having a first width in the first lateral direction and a second width perpendicular to the first lateral direction. The second width is larger than the first width.

摘要： The present invention relates to a device (1) for the generation of micro and nano bubbles of gas in a liquid comprising: an outer tubular body (10) with an extension along a longitudinal axis a-a; an inlet (20) for a flow of liquid; an outlet (30) of the flow of liquid in fluid communication with said inlet (20); a central body (40) contained in a central area of said outer tubular body (10). The central body (40) comprises—a pre-chamber (41) containing a gas; —an air intake (42) in connection with said pre-chamber (41) and with an external source of gas; —a converging element (52), configured to concentrate the flow of liquid at the inlet; —a Venturi chamber (44) in fluid contact with said pre-chamber (41), configured to suck the gas from the pre-chamber (41) and generate micro and nano bubbles of gas in the liquid that passes through it.

摘要： The present disclosure includes mixing apparatuses comprising a pipe having an internal channel having a convergent frustoconical portion, and a divergent portion. The divergent portion may comprise a divergent frustoconical portion and an annular, concave curved portion. A plurality of injection ports may be spaced circumferentially in the convergent frustoconical portion and communicate a liquid into internal channel. The plurality of injection ports may define an opening in the internal channel having a first dimension in a circumferential direction that is larger than a second dimension in a longitudinal direction. The injection mixer may be configured to mix a first fluid flowing through the pipe with the second fluid to form a fully homogenous, dispersed fluid mixture.
