摘要： Apparatus and methods for degassing and analyzing drilling fluid discharged from a wellbore at an oil and gas wellsite. The apparatus may be a drilling fluid analysis system having a gas analyzer, a fluid analyzer, and a degasser operable to release and separate mud gas entrained in the drilling fluid. The degasser may include a gas-liquid separator having a separator inlet configured to receive the drilling fluid containing the entrained mud gas, a first separator outlet for discharging the mud gas fluidly connected with the gas analyzer, and a second separator outlet for discharging degassed drilling fluid fluidly connected with the fluid analyzer.

摘要： A system for removing particulate matter from a multiphase stream comprising gas, liquid and the particulate matter. The system comprises a first vessel for receiving the multiphase stream and separating a majority of gas from the multiphase stream and collecting a slurry of liquid and particulate matter; a second vessel for receiving the slurry and causing separation of the particulate matter from the liquid and for generating a pressure head of liquid against the particulate matter; a third vessel for receiving the particulate matter from the second vessel and collecting the particulate matter until a pre-determined mass or volume of particulate matter is collected; and an outlet in the third vessel for conveying the particulate matter out of the third vessel.

摘要： A pneumatic type water-free starting self-priming device includes a driving device, and a gas-liquid separation chamber and an expandable gas-liquid separation chamber respectively arranged on two sides of the driving device. The driving device uses high-speed gas to drive a drive disk to rotate and drive a drive shaft to rotate. The gas-liquid separation chamber uses a telescopic piston shaft rod to generate a pressure difference between the gas-liquid separation chamber and outside to suck in water, so as to realize water suction, gas-liquid separation and water drainage. The expandable gas-liquid separation chamber uses shrinkage or expansion of volumes of inner and outer chambers to generate a pressure difference to suck in water, so as to realize water suction, gas-liquid separation and water drainage. Also, the high-speed gas from the driving device flows through the two chambers, so that air can be discharged quickly.

摘要： A gas-liquid separator includes a fluid inlet, a shell including an inside surface enclosing an interior space, an outlet structure with fingers converging toward a longitudinal axis, and a dripper including a dripper tip. The fingers terminate at fingertips located proximate to an outside surface of the dripper. Gas exit ports are defined between adjacent fingers, and by the dripper. The gas-liquid separator defines a liquid flow path from the fluid inlet, along the inside surface, along one or more of the fingers, converging along the dripper outside surface, and to the dripper tip. The gas-liquid separator also defines a gas flow path from the fluid inlet, through the interior space, and through the gas exit ports. The gas-liquid separator may be utilized in fluid separation systems such as liquid chromatography or supercritical fluid chromatography/extraction systems.

摘要： A method of removing entrained air from a coolant in a coolant system that may not include a fluid reservoir, includes connecting a de-aeration tank to the coolant system. The de-aeration tank is connected in fluid communication to the coolant system in parallel with a heat exchanger, such that a first connection device connects the de-aeration tank to the coolant system upstream of the heat exchanger, and a second connection device connects the de-aeration tank to the coolant system downstream of the heat exchanger. The coolant is circulated from the coolant system, through the de-aeration tank, and back to the coolant system, with a pump, until substantially all entrained air is removed from the coolant. The de-aeration tank may then be disconnected from the coolant system.

摘要： An electric vehicle drive unit includes an inverter, a gear box, an electric motor coupled to the inverter and to the gear box, a cooling jacket, and coupled to the gear box, a main coolant inlet, a coolant outlet, and an external passive air bleed device. The cooling jacket has a cooling chamber and surrounds at least a portion of the electric motor. The main coolant inlet couples to the cooling jacket. The coolant outlet is located at a lower portion of the gear box. The external passive air bleed device runs between an upper portion of the cooling jacket and the coolant outlet. The inverter may couple to a first side of the gear box and the electric motor may couple to a second side of the gear box such that the inverter and the electric motor reside on opposite sides of the gear box.

摘要： Disclosed is a multi-stage degassing unit for degassing waste water, such as effluent from grain milling processes, through impingement upon successive impact plates. The degassing unit has one or more stages of impact plates, which alternate with redistribution trays that receive the waste water that impinges upon the impact plates directly above the trays and then redistributes the waste water through a plurality of apertures in the redistribution tray. The process of impinging the waste water against the impact plates, collecting the water, and redistributing the water into a plurality of streams may be repeated as necessary to sufficiently remove gas clinging to biomass in the waste water. This degassing will promote the settlement of the biomass for reuse in the water treatment process to reduce biological oxygen demand.

摘要： Systems and methods for automated fluid sampling for tracer testing are described. In one aspect, an automated fluid sampling system includes a pressurized line, such as a production well or an injection well connectively and a fluid separation vessel receiving sample fluids therefrom. The fluid separation vessel includes a plunger and is configured for gravity-mediated phase separation of the sample fluids into a plurality of aqueous, organic and/or gas phase fluid fractions and includes pluralities of inlet and outlet ports for mediating flow of sample fluids therethrough. At least one purging fluid source, such as a gas or liquid, is used for driving the plunger. Sample fluid collection vessels receive phase-separated sample fluids from the fluid separation vessel. Pluralities of fluid lines and solenoid valves operatively link the pressurized line, purging fluid sources, sample fluid collection vessels, and disposal vessel to one another, whereby a controller selectively manages the automated flow of fluids through the various fluid lines.
