Droplet extraction from a liquid column for on-chip microfluidics
InactiveUS20090014394A1Effective drainageAvoid distortionSemi-permeable membranesWithdrawing sample devicesMicrofluidicsDistortion
A refill droplet facilitates the extraction of a droplet laterally from a channel in a microfluidic apparatus. Such extraction allows a discrete band of separated particles or solute molecules to be excised from a fluid stream and processed and analyzed separately. An extraction point is located along the length of the channel and includes an EWOD surface or similar microfluidic technology to extract a droplet. An opening in the channel opposite the extraction means is equipped with microfluidic technology to transport a refill droplet to the opening. The refill droplet is moved into the channel or column to occupy the area previously occupied by the extracted droplet. This prevents distortion or mixing of the bands of particles or molecules within the channel and prevents the draining of any portion of the fluidic system.

Carbon dioxide purification method
InactiveUS20070231244A1Lower energy requirementsLess refrigerationSolidificationLiquefactionPurification methodsRefrigeration
Method of purifying a feed stream containing carbon dioxide wherein the feed stream after having been compressed and dried is partly cooled and then used to reboil a stripping column. Thereafter, the feed stream is further cooled and expanded to a lower operational temperature of the stripping column. A carbon dioxide product stream composed of the liquid column bottoms of the stripping column is expanded at one or more pressures to generate refrigeration, then fully vaporized within the main heat exchanger and compressed by a compressor to produce a compressed carbon dioxide product. Refrigeration is recovered in the main heat exchanger from a column overhead stream extracted from the stripping column within the main heat exchanger either directly or indirectly by auxiliary processing in which carbon dioxide is further separated and optionally recycled back to the main compressor used in compressing the feed stream.

Solar distillation device
A solar distillation apparatus utilizing a substantially vertical reactor assembly is disclosed. The reactor includes a tubular outer shell, a base, a cap, and a central tension member. The annular space between the outer tube and the central tension member forms the reactor chamber. Seawater or other feed liquid enters the reactor chamber through the base plate. Reflected or direct solar energy heats the feed liquid, generating low pressure vapor. The vapor exits the reactor through the cap structure or the base. The concentrate left behind settles by gravity to the bottom region of the reactor's liquid column. Extension tubes on the feed openings allow feed liquid to enter the liquid column above the concentrate layer and avoid excessive mixing of the feed liquid and the concentrate. The concentrate exits the reactor through one or more openings in the base.

Method of monitoring dual-phase liquid and interface levels
InactiveUS6928862B1Removal from serviceSmall diameterSpecific gravity by measuring pressure differencesSurface/boundary effectSpecific gravityContinuous signal
A dual-phase level monitoring (DPLM) instrument that provides continuous signals that enables determination of the location of the top surface of the lighter of two immiscible fluids (the product) and the hydrostatic pressure below the total fluid column of both immiscible fluids. By knowing the fluid specific gravities, the output signals are processed to yield the location of the air / product and liquid / liquid interfaces, and the depth of the lighter phase. The instrument is intended for use in groundwater monitoring wells with a light non-aqueous phase liquid (product) and tanks or vessels with dual-phase liquids and level monitoring and / or control issues. The DPLM instrument includes a first pressure transducer situated beneath the surface of the liquid with a greater specific gravity, which will typically be ground water. A level element with a float selected so as to be buoyant and float on the surface of the lighter fluid is positioned above the first pressure transducer. A signal from the level element is proportional to the position of the float or the total distance the float is positioned above the bottom of the level element and therefore the total distance above the first pressure transducer, the pressure transducer located in the heaver liquid phase. A second pressure transducer can be deployed above the surface of the liquid if greater accuracy of measurement (as compared to assuming ambient pressure) is desired.

A subsea return fluid recovery system for recovering drilling fluid and cuttings (“return fluid”) from a subsea wellbore in one embodiment includes a hub at the opening of the subsea wellbore that directs fluid into a transport device. In one embodiment, the hub includes a stand pipe that forms a return fluid column, the hydrostatic pressure of which causes return fluid to flow into the transport device rather than up the stand pipe. One or more buoyant members attached to the transport device convey the transport device toward the surface. A preferred recovery method includes collecting return fluid at the seabed, passively transporting the collected fluid to the surface, and processing the collected fluid at a local (offshore) or land based treatment facility. The retrieval and processing of the return fluid is done outside the critical path of the drilling activities at an offshore platform.

This invention provides an automatic control system and method for bottom hole pressure (BHP) in the underbalanced drilling. It relates to a computer automatic control technology. The automatic control system according to the invention includes a processing module for the BHP based on the mechanisms of hydraulics. The BHP in the underbalanced drilling is calculated from the acquired standpipe pressure (SPP), the calculated circulating pressure loss in the drilling tools, drill bit pressure drop and the fluid colunm pressure in the drill string. The resulting BHP is then compared with the set pressure value of the system. In case that the BHP is higher or lower than the set pressure, an instruction to regulate throttle valve opening will be issued in order to bring the BHP back to the set pressure range and complete BHP monitoring and control.

Molten iron is subjected to shaping and continuous casting under multiple physical fields to become the hollow sections. The molten iron in heat preserving furnaces is separated from dross, sand and gas in twoways, thus completely solving the defects of dross inclusion, sand inclusion and pores; liquid column cores in a crystallizer carry out continual feeding on condensing tube shells, thus eliminating the possibility of shrinkage porosity inside the tube walls, obtaining highly dense cast structure of (ferritic matrix+spherical graphite) and eliminating crack initiation origins in thermoplastic deformation to be carried out later. The intense cooling speed in the crystallizer enables the volumes of eutectic cells to be only 1 / 15-1 / 25 of the volumes of traditional sand mould casts. The density ofthe graphite balls reaches around 500 / mm<2>. In plastic deformation, the micro slip orientation is increased and the ductility is enhanced, therefore, the hollow cast iron sections can be arced by medium frequency induction heating and bending.
