An agitating/defoaming apparatus adjusts a rotation speed and, even with respect to a material high in viscosity, prevents or reduces an increase in temperature of the material during agitating/defoaming. The agitating/defoaming apparatus includes a plurality of container holders, each holding a container. A revolution member supports each container holder so as to be rotatable, is provided in such a way as to be rotatable on a first rotational shaft, and causes each container holder to revolve around the first rotational shaft. A first drive rotationally drives the revolution member. A control unit performs drive control. An annular outer ring is arranged to surround the container holders in such a way as to be in abutting contact with an outer circumferential portion of each container holder. An outer ring rotation mechanism rotates the outer ring with a central axis of the outer ring set coincident with that of the revolution member.

A method of upgrading an overflash stream from a vacuum distillation unit comprising the steps of separating the overflash stream from an atmospheric residue stream, the overflash stream comprises an overflash fraction having a T10% between 475 and 530° C. and a T90% between 600 and 700° C.; introducing the reactor feed to a supercritical reactor at a temperature between 380° C. and 500° C. and a pressure between 25 MPa and 30 MPa; maintaining upgrading reactions in the supercritical reactor to upgrade the overflash fraction such that a reactor effluent comprises upgraded hydrocarbons relative to the overflash fraction; reducing a temperature of a reactor effluent in a cooling device to produce a cooled stream; reducing a pressure of the cooled stream in a depressurizing device to produce a discharged stream; and separating the discharged stream in a gas-liquid separator to produce a liquid phase product.

A fuel oxygen conversion unit for a vehicle or an engine of the vehicle includes a contactor; a mechanically-driven, first fuel gas separator defining a liquid fuel outlet and a stripping gas outlet, the fuel oxygen conversion unit defining a liquid fuel outlet path in fluid communication with the liquid fuel outlet of the first fuel gas separator; and a second fuel gas separator positioned in fluid communication with the liquid fuel outlet path at a location downstream of the first fuel gas separator.

Provided is a defoamer for a fermenter. A defoamer for a fermenter according to an embodiment of the present invention includes: a body (100) having a first hollow (110) at a central portion thereof and having a disk shape; a support (200) having a second hollow (210) connected with the first hollow (110), and extending from an upper surface (120) and a lower surface (130) of the body (100); and a plurality of first vanes (310, 320, 330, 340, 350, 360, 370, and 380) mounted on the lower surface (130) of the body (100).

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.

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.

Disclosed is a system for producing magnesium hydroxide including: a generation unit; and a recovery unit connected to the generation unit, wherein the generation unit has a reaction tank in which a calcium hydroxide slurry is added to water to be treated containing magnesium ions to crystallize magnesium hydroxide and to obtain a reaction slurry containing particles of magnesium hydroxide, and a sedimentation tank in which the reaction slurry is reserved to sediment the particles and to separate the reaction slurry into a separation slurry containing the particles at a high concentration and a separation liquid containing the particles at a low concentration, and wherein, in the recovery unit, an alkaline aqueous solution is added to the separation liquid to crystallize magnesium hydroxide and to obtain the reaction slurry and then the reaction slurry is reserved to sediment the particles and to recover the sedimented particles.

A system for producing magnesium chloride includes a removal unit, and a concentration unit that is connected to the removal unit. The removal unit generates feedstock water by removing sulfate ions and sodium ions from treatment target water having seawater as a feedstock. The concentration unit generates a slurry in which magnesium chloride is crystallized by concentrating the feedstock water. The removal unit has a first removal unit which reduces the sulfate ion concentration compared to the sulfate ion concentration in the treatment target water, and a second removal unit which reduces the sodium ion concentration compared to the sodium ion concentration in the treatment target water.
