A subsea multiphase fluid separation system has a gas separator for separating gas from a well stream containing oil. A water separation stage downstream of the gas separator has at least one dual pipe separator for separating water from the oil of the wellstream. A water treatment system for cleaning oil from water is produced by the water separation stage. On an oil outlet path, downstream of the or each dual pipe separator, there is an electrocoalescer and at least one second separator in series.

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.

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.

A device which includes a pulse dampener and a degasser or de-bubbler. The device includes a fluid flow path and a fluid chamber located within the device. In addition, the device includes a pulse dampening membrane for dampening pulses in the fluid as it flows through the device. The device also includes a degassing membrane for degassing the fluid as it flows through the device, and/or a de-bubbling membrane for removing gas bubbles from the fluid as it flows through the device. The degassing or de-bubbling membrane can be separate and distinct from the dampening membrane. The de-bubbling membrane can be in addition to or in place of the degassing membrane in some embodiments.

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.

An aquarium filtering and purifying system includes an upper display tank and a lower filter tank. The water from the upper tank can be delivered to the lower tank to a filter, such as within a surrounding filter fabric or membrane, such as a filter sock. An air tube can also be inserted into the filter tank to an unfiltered side of the filter, such as within the filter sock, to deliver air bubbles into the filter tank. The air tube can have an air stone at the end thereof to diffuse the air bubbles. Further air stones can be provided on an outside of the sock in the first compartment. Filtered water is delivered to a second compartment in the filter tank. The next compartment can have sand, and/or rocks and/or algae and/or a clean-up crew to assist in purifying the water. Water from the second compartment then passes to a third compartment, through a bubble trap, and then is pumped back to the display tank. Alternatively, the first compartment can be provided with a macro algae bed instead of a filter sock.

A gas-liquid separator includes a first cylinder body, a second cylinder body, a first flow guide portion, a second flow guide portion, a gas-liquid distribution assembly and a heat exchange assembly. The first cylinder body is located inside the second cylinder body. The gas-liquid separator has a first cavity and a second cavity. The heat exchange assembly is at least partially located in the first cavity. The heat exchange assembly includes a heat exchange tube, a first heat exchange member and a second heat exchange member. The heat exchange tube at least partially surrounds the first cylinder body. The first heat exchange member and the second heat exchange member have different structures. A thermal management system having the gas-liquid separator is also disclosed.

A hydraulic tank for a machine is disclosed herein. The hydraulic tank includes a casing defining an interior space and having an outer surface, an inner surface opposite the inner surface, and a return hydraulic fluid inlet extending through the casing. A first concave member is connected to the inner surface of the casing to form a passage. The passage is positioned and shaped to transport hydraulic fluid from the return hydraulic fluid inlet to another location within the hydraulic tank.

Disclosed is an air conditioner. The air conditioner of the present disclosure for achieving the above or other object, there is provided an air conditioner including: a compressor which compresses refrigerant; an accumulator which supplies refrigerant to the compressor; a condenser which condenses refrigerant discharged from the compressor; an expansion valve which expands refrigerant passing through the condenser; an evaporator which has a heat exchange pipe through which refrigerant passing through the expansion valve flows, and evaporates refrigerant flowing through the heat exchange pipe; a gas-liquid separation pipe which connects a first point and a second point located between one end and the other end of the heat exchange pipe; and a bypass pipe which has one end connected to the gas-liquid separation pipe and the other end connected to the accumulator, wherein the gas-liquid separation pipe comprises: a first part which has one end connected to the first point and the other end connected to one end of the bypass pipe; and a second part which extends from the first part at between one end and the other end of the first part, and is connected to the second point.

A vortex reservoir for separation of an aerated portion of a hydraulic fluid includes an upper chamber and a lower chamber, in fluid communication with the upper chamber, having a lower chamber sidewall. The lower chamber includes a lower lower chamber and an upper lower chamber. The lower chamber includes a lower chamber partitioning plate. The lower chamber partitioning plate is located between the lower lower chamber and the upper lower chamber. The lower lower chamber is in fluid communication with the upper lower chamber via a gap between the lower chamber partitioning plate and the lower chamber sidewall.
