The present disclosure relates to a process for the preparation of polyethylene by polymerizing in a slurry ethylene and optionally one or more C.sub.3 to C.sub.10 alpha-olefins. In some embodiments, the polymerization is carried out in a cylindrical polymerization reactor equipped with an agitator for mixing the contents of the reactor and inducing a flow of the slurry, the ethylene is fed into the reactor by an ethylene injection system comprising one or more injection nozzles which project through the bottom reactor head or through the reactor wall and extend from 0.02-0.5 times the inner diameter D into the reactor, and the ethylene exits the injection nozzle with an exit velocity from 10-200 m/s.

The present invention relates broadly to microfluidic devices, particularly microfluidic devices optimised for the industrial production of nanoparticles such as liposomes. The device (101) comprises a substrate which extends between a distal end (107) comprising an outlet region (105) and a proximal end (108) comprising an inlet region (106). The inlet region comprises two substantially parallel outer channels (103a, 103b) for transport of a first fluid, said outer channels (103a, 103b) defined in part by a first outer wall (109a) and a second outer wall (109b) respectively, and a linear inner channel (104) for transport of a second fluid. The linear channel is disposed between the two substantially parallel outer channels. The outer channels (103a, 103b) and inner channel (104) extend from the proximal end (108) to a mixing chamber (102) which extends from the inlet region (106) to the outlet region (105). The mixing chamber (102) is in flow communication with the inner and outer channels (103a, 103b, 104) to receive the first and second fluids from the inner and outer channels (103a, 103b, 104) and the mixing chamber (102) has a uniform width (W) along its length substantially equal to the width (W1) between the outer walls (109a, 109b) of the two substantially parallel outer channels (103a, 103b).

An apparatus for mixing wash water and crude oil includes a crude oil pipe, a wash water manifold, a plurality of conduits, and a flow controller. The crude oil pipe includes a wall having an interior surface, an exterior surface, and a plurality of wash water injectors. The plurality of wash water injectors are angularly distributed on a circumferential band of the wall of the crude oil pipe. The flow controller is operable to regulate wash water flow through the plurality of conduits. Each of the plurality of wash water injectors is fluidly coupled to the wash water manifold by one of the plurality of conduits. The plurality of wash water injectors are arranged to provide mixing of the wash water and the crude oil when the wash water is injected into the crude oil pipe through the plurality of wash water injectors.

A fluid mixing unit includes a cylindrical porous body partitioning a container into a first flow space and a second flow space surrounding the first flow space. A first supply port supplies a first fluid to one of the first and second flow spaces. A second supply port provided on one end side of the container in an axial direction of the cylindrical body supplies a second fluid to the other flow space. An outlet for a mixed fluid is provided on the other end side of the container to be open only to the other flow space. Closing members are provided in a plurality of stages along the axial direction to alternately close a right and a left of the other flow space as seen in the axial direction in the other flow space. A meandering flow is formed in the other flow space to create the mixed fluid.

A mini mixer system includes a mixer, for executing a continuous mixing operation for an extended period of time, the mixing operation includes a mixing production process with corrosiveness, high viscosity and high mixing risks. The mixer includes a motor, a coupling and torsion meter, a reduction gear, a plurality of couplings, a frame group, a gear box group, at least one mixing element, a mixing can and a lifting mechanism group. The motor, the coupling and torsion meter and the reduction gear are connected to one another by the couplings. The reduction gear is connected to the gear box group by the coupling. The motor, the reduction gear, the gear box group and the lifting mechanism group are all fixed on the frame group. The mixer is assembled in a gear mechanism of the gear box group. The mixing can is disposed on the lifting mechanism group.

The present invention generally relates to microfluidic droplets and, in particular, to multiple emulsion microfluidic droplets. In one set of embodiments, multiple emulsion droplets are provided, where an inner shell of the droplet is relatively thin, compared to the outer shell (or other shells) of the droplet. For instance, in one set of embodiments, the inner droplet has an average thickness of less than about 1000 nm. In some cases, the inner shell may be rigidified, e.g., to form a gel or a polymeric layer. This may be useful, for example, for preventing coalescence of fluids within the microfluidic droplet. Other embodiments of the present invention are generally directed to methods of making such droplets, methods of using such droplets, microfluidic devices for making such droplets, and the like.

Embodiments of the disclosure produce a method and system for deasphalting a hydrocarbon feed. The hydrocarbon feed and a first solvent is combined using a Taylor-Couette mixer to form a mixed stream. The mixed stream and a second solvent are introduced to an extractor to produce a first deasphalted oil stream and a pitch stream. The first deasphalted oil stream is introduced to a solvent recovery unit to recover the first solvent and the second solvent via a recovered solvent stream and to produce a second deasphalted oil stream.

A unit for grinding biological samples, comprising a grinding device including at least two tubes having different volumes, suitable for being mounted on a support of the grinding device, each tube comprising an inner space having a height (h) along the axis of the corresponding tube, and being intended to contain samples to be ground, means for driving the support in a precession movement, the support having an axis the position of which varies by describing a cone, each tube being subjected to a movement (d) defined by the projection, onto the axis of said cone, of the distance between the extreme positions of a same point of the tube during the precession movement.

A diluted solution production method of the present invention is a diluted solution production method of producing a diluted solution of a second liquid by adding the second liquid to a first liquid, the method including feeding the first liquid to a first pipe; and controlling pressure in a tank that stores the second liquid to add, through the second pipe that connects the tank to the first pipe, the second liquid to the first liquid in the first pipe. Adding the second liquid includes measuring a flow rate of the first liquid or the diluted solution that flows through the first pipe; measuring a component concentration of the diluted solution; and controlling the pressure in the tank, based on the measured values of the flow rate and the component concentration, so as to adjust the component concentration of the diluted solution to a specified value.
