Compressed gas system useful for producing light weight drilling fluids

A compressor station having at least one primary compressor and a booster compressor is controlled to conserve energy and air, and to respond quickly to sudden changes in demand for air, by employing a volume bottle to buffer changes in air pressure and by recycling already compressed air from the intake to the output of the booster compressor. The system may be used in air drilling and to provide compressed air for generating low density drilling fluid on site by injecting microbubbles into a base drilling fluid. Two different methods of generating microbubbles are illustrated. The primary and booster compressors are kept in a state of readiness during drill pipe connection time, providing for a rapid resumption of pressure and air flow after connection is completed. The system can utilize gases other than air.

Methods and apparatus for treating materials in liquids

The method for treating materials in liquids involves passing them with the liquid through a processing gap formed by a flow passage whose walls are closely spaced and move relative to one another transversely to the direction of flow, thereby producing "supra-kolmogoroff" mixing eddies in the gap, and at the same time applying ultrasonic longitudinal pressure oscillations that reverberate between the two closely spaced surfaces into the gap transversely to the direction of flow from transducers mounted on one wall, thereby producing "sub-Kolmogoroff" mixing eddies therein. The method is capable of rapidly producing relatively thick slurries of sub-micrometer particles that otherwise can take several days in conventional high shear mixers and ball or sand mills, or of rapidly dissolving difficultly soluble gases and powders into liquids. One type of apparatus consists of two circular coaxial plates, one stationary while the other is rotated, the opposed faces forming the processing gap being mirror finished; the rotational axis can be vertical or horizontal. Another type consists of an inner cylinder rotatable about a horizontal axis inside a stationary hollow outer cylinder with the facing walls closely spaced at their lowermost parts to form the processing gap. The ultrasonic transducers are mounted on the stationary member. The liquid/material mixture may be recirculated through a single mill or may be passed through a series of mills. The mixture may be pretreated in a high capacity reverbatory ultrasonic mixer before being fed to the mill or series of mills.

The raw material is mixed and refined during the relative rotation between the rotor (26) and the drum (10) in a plurality of co-axially extending grinding areas (30) defined between rotatable grinding elements (40) on the rotor (26) and a facing grinding surface (28) on the interior of the drum while being simultaneously compressed therein and alternately decompressed in areas between the grinding areas (30). The rotatable elements (40) are adjustably mounted to the rotor (26) so as to vary the spacing between the grinding surface (28) on the interior of the drum and a rotatable grinding surface (42) on the grinding elements (40), while simultaneously adjusting the material feeding angle of the grinding areas (30). The adjustment can be achieved mechanically or by a hydraulic system during the operation of the apparatus to control and vary the flow of the pulp material as it passes through the grinding areas (30) to insure optimum and even mixing and refining of the pulp.

1,111,387. Extracting liquid from slurry. G. A. HARVEY & CO. (LONDON) Ltd. 5 April, 1965 [10 Jan., 1964], 1206/64. Heading BID. . Liquid is extracted from a slurry or suspension by passing the mixture along an annular chamber defined by a barrel member 8 enclosing a worm member 6, the barrel and worm having respective helical grooves 12, 10 whose threads are of opposite hand and which vary in depth in opposite senses along the chamber, portions of the chamber walls being porous for extraction of liquid therethrough by pressure under which the mixture is delivered to the device. As shown, the barrel and worm each have additional helical grooves 14, 16 which are covered by porous metal ceramics or plastics elements (18) (Fig 2 not shown) and which communicate by holes (24), 20 with liquid outlet (22) (Fig. 3, not shown) and hollow interior 17 of worm 6. As shown, the worm is rotated by motor 40 within stationary barrel 8, but the barrel alone could rotate, or both worm and barrel could be fixed or rotate. Heating and/or cooling jackets may be provided. The barrel and worm narrow at the solids discharge end, and grooves 14, 16 stop short of that end, which is closeable by a plate 33 moved by rams 36. Initially, plate 33 is held against end 38 of barrel 8 as shown, while mixture is delivered to inlet 52. Once pressure has built up, plate 33 is withdrawn rightwards and solids are discharged from the right hand end 38 of the barrel. Liquid extracted is either discharged at outlet 53, together with any fluid from seal 50, or by resetting a valve (Fig. 2, not shown) the liquid may pass through conduit 30 and a corresponding central hole through shaft 34 to which suction is applied. Solids removed from one device may be mived with fresh liquid and delivered to another similar device. A screw 48 is provided for axial adjustment of worm 6 within the barrel, whereby the radial spacing between the crown portions of worm and barrel is varied.

Extensional flow mixer

An extensional flow mixer especially for viscous liquids has a housing (10) with an end inlet (12a, 14a) connectable to a pressurized source of the liquids, and an outlet (119) at an opposite end of the housing (10). A mandrel (30) located in the cavity has protrusions (20', 32') with sloping side surfaces, the outer edges of which cooperate with the internal surface (114a) of the cavity to divide the cavity into a series of chambers separated by slits, such that liquid passes successively through all the chambers and slits in moving from the inlet (12a, 14a) to the outlet (119). The slits have cross-sectional areas which decrease in the liquid flow direction. The mandrel (30) sides have helical grooves (134) forming passageways with the housing wall (114a) which allow liquid to be distributed evenly around the edges of the mandrel (30) to the inlet end or upstream chamber. The mandrel (30) may rotate to provide additional shear mixing.

Methods of operating surface reactors and reactors employing such methods

New methods of operating surface reactors, and such reactors, particularly spinning disk reactors, require that a first reactant is fed to a reactor surface (20) and forms a thin radially outward moving film (60) thereon in a reaction passage (42) formed between the reaction surface (20) and a parallel, closely spaced (less than 1 mm) retaining surface (40). The passage thickness is precisely controllable and the surfaces (20, 40) move relative to one another so that strong shear is applied to the material between them. A second reactant is fed to the surface (20) as a second thin film (65) that as it enters the first film (60), preferably perpendicularly, it is immediately merged therewith along a correspondingly very narrow interaction line (66) by the shear at a rate such as to break up molecular clusters in the films, so that their molecules can aggressively and completely interact by forced interdiffusion. In spinning disk (18) apparatus the first film (60) is fed along the spin axis (14), while subsequent films (65, etc.) are fed at respective distances from the axis (14) such that there is adequate shear for the molecular cluster disruption. Preferably each film (65, etc.)after the first (60) is fed into the reaction passage (42) through a respective thin annular nozzle producing a thin circular film (65) that simultaneously merges with the first film (60) along its entire length.

Atomizing device

Methods and apparatus for high-shear material treatment

High-shear treated materials are passed through a high-shear treatment zone which allows the coexistence of free supra-Kolmogoroff eddies larger than the smallest possible Kolmogoroff eddy diameter and forced sub-Kolmogoroff eddies smaller than this diameter. This zone includes a subsidiary higher-shear zone for suppressing these free eddies. The passage walls (40, 44, 102, 108) move relative io one another transverse to the flow to force the simultaneous development of supra-Kolmogoroff and sub-Kolmogoroff eddies while maintaining liquid films adherent to the passage surfaces. The movement produces only forced sub-Kolmogoroff eddies in the susidiary zone while maintaining a non-turbulent flow. Ultrasonic oscillations (52) may be appli-ed to cause elastohydrodynamic pressure and viscosity increases and/or production of smaller sub-Kolmogoroff eddies. One ap-paratus includes an inner cylinder rotatable (46) inside a hollow outer cylinder (38), another consists of two circular coaxial plates, and the rotational axis can be vertical or horizontal.

Kneading device

A kneading device includes: a preliminary kneading device that produces a preslurry by agitating a powder and a liquid introduced and transferring them while wetting the powder with the liquid; and a main kneading device that causes the powder to be uniformly dispersed in the preslurry supplied from the preliminary kneading device to produce a slurry. The main kneading device includes a gap defined by two conical surfaces that face each other with a predetermined distance therebetween and rotate relative to each other about their central axes. The slurry is produced by passing the preslurry through the gap. With the preliminary kneading device, the powder is dispersed in the liquid after conforming to the liquid, which suppress damage to the powder. The conditions of main kneading can be changed only by adjusting the gap, which facilitates the operation of changing the conditions of the main kneading.

Mixing apparatus and method of preparing edible dispersions

Disclosed is a mixing apparatus which is characterized by a specific range of cavity diameters in combination with a specific range for the size of the inner element (i.e. the maximum diameter, typically of the rotor). Said mixing apparatus provides good shear and distributive mixing with low energy dissipation (i.e. low temperature increase of the mixture due to the mixing process) and allows the manufacture of edible dispersions at a wide range of mixture throughput levels. Also disclosed is a process using said mixing apparatus for the manufacture of edible dispersions.

Particle size breakup device and its performance estimation method and scale up method

Herein is disclosed a comprehensive mixer performance estimation method that can be applied to the mixers of the rotor-stator type having various configurations and circulation systems. Specifically, the performance estimation method for the mixers of the rotor-stator type includes the steps of: obtaining the homogenization index: H.I. for each of the mixers, measuring the size of each of the mixers, the powder requirements and flow rates during the running time of each of the mixers, estimating the magnitude (smallness or greatness) of the configuration dependent term value of each of the mixer as whole which is specific to each of the mixers, and estimating the performance of each of the mixers accordingly.
