Impure portions such as air bubbles and gelled portions in a liquid are removed so that the liquid can be discharged with improved cleanliness. Under condition that a return flow path and a liquid discharge flow path are closed, a pump chamber is expanded, thereby sucking the liquid in a liquid container portion into a pump chamber through a filter. Under condition that a vent port of the filter and the return flow path are opened and a liquid introducing flow path, the liquid discharge flow path, and a pump inlet flow path are closed, the pump chamber is contracted, thereby returning the liquid in the pump chamber toward the filter so that air in the filter is exhausted to the outside. Under condition that the return flow path and the pump inlet flow path are closed, the pump chamber is contracted, thereby discharging the liquid from the nozzle.

A system is provided for proceeding with filtration of liquids in a manner having enhanced control characteristics. Yields are enhanced. The system and method can be used to maintain a substantially constant trans-membrane pressure.

Additionally, a constant feed rate or pump output can be maintained. Approaches also are described for determining optimal filtration conditions, including trans-membrane pressure and feed rate. Also described is a system and method for determining pressures in a pulsating system with enhanced accuracy by using a peak pressure mode.

A system and process are provided for recovering and/or cleaning residual or waste petroleum products such as sludge accumulated within a storage tank or upon process equipment surfaces, or from inorganic materials such as sand or clay, and the like. The system and process include a negatively charged aqueous-based dispersion fluid, which is contacted with the petroleum product under controlled relatively high pressure and high shear conditions for fluidizing hydrocarbon molecules and for preventing such molecules from adherence to process equipment surfaces, or contaminants such as sand or clay. Additional mechanical separation as by subjecting the mixed petroleum product and dispersion fluid slurry to sonic vibration may also be employed. The thus-fluidized slurry of petroleum products, dispersion fluid, and inorganic materials can be separated by conventional techniques, as by settling and/or flotation, for further individual processing and/or re-use.

A method according to one embodiment comprises simultaneously passing a sample fluid and a buffer fluid through a chamber such that a fluidic interface is formed between the sample fluid and the buffer fluid as the fluids pass through the chambers the sample fluid having particles of interest therein; applying a force to the fluids for urging the particles of interest to pass through the interface into the buffer fluid; and substantially separating the buffer fluid from the sample fluid.

Embodiments in accordance with the present invention relate to the use of effusive filtration to segregate tumor cells from a sample of bodily fluid. In one embodiment, fluid containing a cell is flowed down a channel having a filtration medium present along at least one side wall. The tumor cell is captured when the fluid passes through the filtration medium. Accumulated pressure on the captured tumor cell is reduced by allowing the fluid that has passed through the filtration medium to re-enter the channel. In a particular embodiment, the filtration medium may comprise side wall apertures having a width smaller than that of the cell, with downstream apertures allowing re-entry of the fluid into the channel.

The optical measurement can also be used to calculate an amount of storage fluid to convey into a collection container with the blood component.

Subsea wells are drilled and completed with an offshore floating platform in a manner that allows simultaneous work on more than one well. A first well is drilled and cased. Then a tubing hanger is run through a drilling riser and landed in the wellhead housing. Then, with the same floating platform, the drilling riser is disconnected and moved to a second well. While performing operations on the second well, the operator lowers a production tree from the floating platform on a lift line, and connects it to the first wellhead housing. An ROV assisted subsea plug removal tool is used for plug removal and setting operations. Seabed separation is configured upstream of a production choke valve.
