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.

The present disclosure relates to an apparatus for preparing an oligomer, including: a reactor receiving a monomer stream and performing an oligomerization reaction to prepare a reaction product; a product discharge line for transferring a reaction product stream discharged from the reactor; and a bubble catcher provided in any area of the product discharge line to remove bubbles contained in the reaction product stream.

A microflotation system comprises a flotation tank with a dispersion water feed line in which an expansion valve arrangement is disposed. An adjusting apparatus is configured to adjust a flow rate of the expansion valve arrangement and an electronic control is connected to the adjusting apparatus. A measuring apparatus is disposed downstream from the expansion valve arrangement for detecting a size distribution of gas bubbles and the electronic control is configured to set the flow rate depending on a size distribution detected with the measuring apparatus.

The present disclosure relates to a degasification apparatus having means to contact and interact with liquid flow, degas liquid, reduce or eliminate turbulent flow, and in most cases increase liquid flow rate.

Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

A subsea separator vessels includes single machined blocks integrated into a hull so as to combine all the valves used in the process of separating the multiphase fluid in the interior of the blocks. The separator vessels have by-pass valves in their blocks, if necessary to interrupt the separation process. The blocks function as a structure for the separating vessels, thereby replacing all of the metal structure necessary to support the tubes and valves of a conventional manifold, thus reducing the total area occupied by the separation station in the seabed.

A device for the treatment of fluid mixtures containing gases, such as in particular hydrogen, air, nitrogen or noble gases, and liquids, such as in particular ionic liquids, hydraulic oil or process liquids, having at least one separating stage (30) for separating the fluid mixture into a gas portion and a liquid portion, which, routed into a collection space (32), results in a float (44) rising, which, at a predeterminable liquid level in the collection space (32), actuates, without contact, a sensor device (42), which preferably actuates a discharge device for the purpose of draining the collection space (32), resulting in the lowering of the float (44), is characterized in that the outer circumference of the float (44) is guided axially displaceably along the inside of the housing wall (54) of the collection space (32), and in that the float (44) has at least one point of passage (50) for gas and/or liquid, which interconnects parts of the collection space (32) in a media-conveying manner, which parts are spatially separated from one another by the float (44).

The present invention discloses a centrifugal fuel purifying apparatus, including, a center shaft, a centrifugal cylinder, a shaft seat, a rotating skeleton, a disc type guide plate, a fuel gathering impeller, a rotating wheel, a vacuum pump, a fuel outlet pipe, a fuel inlet, pipe, a fuel unloading box, a pollutant receiving box, a tank body and a PLC controller, wherein the alarm fuel tank is arranged at the top in a tank body of the fuel tank, a fuel level meter is disposed within the alarm fuel tank, a fuel inlet is provided on the upper part of one side of the alarm fuel tank above the fuel level meter, a fuel outlet is provided on the lower part of one side of the alarm fuel tank below the fuel level meter, and the fuel inlet is communicated with the centrifugal cylinder through the fuel inlet pipe.

An air bleeder includes a branch, a lubricant supply conduit, and a return conduit. Lubricant stored in a tank is to be supplied to a valve provided in a machine tool via the lubricant supply conduit. The lubricant supply conduit includes a first supply conduit, and a second supply conduit. The first supply conduit connects the branch and the tank. The second supply conduit connects the branch at a first connecting position and the valve. The return conduit connects the tank and the branch at a second connecting position higher than the first connecting position in a height direction along a height of the air bleeder to return lubricant to the tank and to remove air from lubricant in the lubricant supply conduit.

A gas separator for separating a multiphase medium containing a gas and a liquid includes a tubular basic unit having a longitudinal axis, an intake for a gaseous medium, a liquid outlet and a gas outlet. The tubular basic unit has an intake region and a discharge region. The gas separator includes, between the intake region and the discharge region, a weir having a guiding surface, over which the medium can flow to form a shallow water region. The gas contained in the medium can escape from the medium in the shallow water region and be led away from the gas separator through the gas outlet. The disclosure is also directed to an apparatus for registering flow of at least one component of a multiphase medium.
