The rotational absorber device comprises a housing having a gas inlet, a gas outlet, an absorbent liquid inlet and an absorbent liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor comprising a plurality of scrubbing channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. The device and method provide a scrubbing of the gas with improved selectivity and efficiency.

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 device for treating fluid mixtures, which contain gases, such as hydrogen (H2), air, nitrogen (N2), or natural gases, and liquids, such as ionic liquids, hydraulic fluid, or process liquids, has a first separation stage (29) for separating the fluid mixture into a liquid fraction and a gas fraction contaminated with a remaining liquid fraction. From the gas fraction, the remaining liquid fraction is removed in at least one further separation stage (67).

A bubble removing system and a bubble removing method are provided. The bubble removing system comprises a main bubble removing apparatus which comprises a first enclosed container, a first fluid lead-in pipe, a first fluid lead-out pipe, and a bubble collecting member. The cross section of the inner cavity of the first enclosed container is circular, and the first enclosed container is used for accommodating a fluid substance. The first fluid lead-in pipe passes through a sidewall of the first enclosed container, is tangent to the inner cavity wall of the first enclosed container, and is disposed at the upper part of the first enclosed container. The first fluid lead-out pipe passes through the sidewall of the first enclosed container and is disposed at the lower part of the first enclosed container.

An improved apparatus for filtration has a fluid mixture feed comprising light and heavy fractions fed into the workspace between counter-rotating disk impellers within a tank, thereby forming vortices in the workspace. A static radial exhaust array is located axially in the workspace, comprising exhaust channels, each of which has a peripheral end facing the workspace and an inner end communicating with an axial exhaust drain. An axial pump produces low pressure in the axial exhaust drain, thereby drawing in and anchoring the vortices to the peripheral ends of the exhaust channels so that the exhaust channels can extract the contents of the vortex cores. Vanes can be incorporated into the workspace surface of each disk impeller so that the opposed vanes pass in close proximity, forming vortices along a plurality of radial lanes of intersection, with the peripheral openings of each of the exhaust channels aligned with at least one of the lanes of intersection in the workspace. The feed can be a peripheral feed which enters the workspace radially inward through the periphery of the workspace, or the feed can enter the workspace radially outward through a static axial feed array.

A centrifugal separator includes a stator assembly (114) that includes at least one housing (116), and a rotor assembly (112) positioned within the at least one housing. The rotor assembly includes a rotor shaft (132), an array of longitudinal fins (189) extending radially outward from the rotor shaft, and a plurality of separator vanes (134) coupled to the array of longitudinal fins. Each separator vane includes a plurality of longitudinal slots (194) defined therein and configured to align with the array of longitudinal fins such that the plurality of separator vanes are rotationally interlocked with the array of longitudinal fins.

An at least two shaft reactor/mixer, in particular for process engineering treatment of highly viscose, elastic and/or solid containing reaction substance and mixture, in which at the housing inner wall inwardly directed static mixing elements are arranged, which interact with scrapers of the at least two shafts in such a way, that in the area of the spaces between the scrapers the static mixing elements and the housing inner wall sheer forces, in particular a flow disturbance, are generated in an enhanced manner. In addition, there is a system including an end cap for a one or multiple shaft reactor/mixer and a discharge screw connector block being connectable with the end cap in a detachable manner.

Seawater is deaerated using a rotating packed bed device having one or more rotatable packing rings within a housing, a liquid inlet for infusing seawater into an interior region defined by the packing rings, a gas outlet for accepting gas which has passed radially inwardly through the packing rings and removing the gas from the interior region, and a liquid outlet for removing a deaerated seawater stream from the housing. A shaft coupled to a motor drives the packing rings causing the packing rings to rotate. The feed seawater stream passes radially outwardly through each of the packing rings thereby forming the deaerated seawater stream having a lower concentration of oxygen, air and/or carbon dioxide therein than the feed seawater stream and a gas stream having been removed from the feed seawater stream. The deaerated seawater stream is then injected into a hydrocarbon producing reservoir in an EOR process.

An agitation/defoaming device is provided, which can independently control revolving and rotational motion and can change a rotational direction relative to a revolving direction without a two-system rotary drive.

The apparatus includes a rotary driving source, a braking device for rotary motions; first and second rotors revolved around revolving shaft, and first and second rotational bodies container holders pivotally supported by the first rotor. A breaking force is applied to the second rotor revolving along with the first rotor, generating a rotational motion, which is transmitted to either the first or second rotational body according to the revolving direction of the first rotor. The rotational motion is then transmitted from the first or second rotational body to the container holder through the first rotational body, thereby transmitting to the object the rotational motion according to the revolving direction while revolving the object.
