Apparatus for transporting fluid within a biological subject, the apparatus including an at least partially compliant section, so that the compliant section at least partially controls the flow of fluid therethrough. The compliant section may also be used in conjunction with a heart pump for the purpose of at least partially controlling the flow of blood through the heart pump.

A separator and a phase-splitting conveying method for eliminating severe slug flow by using the separator. The separator includes a shell, which is connected with an incoming flow pipe and a gas riser pipe, and is provided with a liquid level sensor and a pressure sensor on the shell. A riser pipe is inserted and extended to the bottom of the shell, the part of the riser pipe protruding from the shell is provided with a liquid phase pump connected to the riser pipe through a valve, and a control valve is set on the gas riser pipe close to the outlet of the shell. The separator of the present invention is installed at the junction of the mixed pipeline and the rising pipe, the gas-liquid fluid in the mixed pipeline enters the shell of the separator through the incoming flow pipe, and the liquid level signal and pressure signal are used to adjust the control valve. The opening makes the liquid level and pressure stable. After the gas and liquid are separated in the separator, the liquid enters the riser and is pressurized by the liquid phase pump to be transported to the onshore platform device. The gas enters the onshore platform device through the gas riser through the control valve. The invention has a simple structure, can conveniently and accurately control the flow of gas and liquid, and achieves the purpose of eliminating severe slug flow.

A waste heat source (100) is used to heat a high temperature heat transfer fluid which is used to heat an absorption heat transfer machine (10) having a generator (20), an absorber (30), a condenser (40), and an evaporator (50) operatively connected together. The high temperature heat transfer fluid can also be used to heat a load (190) such as a room space or a process. The waste heat source (100) can also be used to heat an intermediate heat transfer fluid, which can be used to heat a second load (175) such as a space, a process, or an absorption heat transfer machine. Novel flow control devices (70, 60) for controlling the flow of weak solution from generator (20) to absorber (30) or of refrigerant from condenser (40) to evaporator (50), respectively, are also described.

A multi-stage compressor, for an air separation unit comprising such a compressor and to an installation is provided.

The present invention discloses a confection process of synthesized methanol diesel. The process mainly includes the following steps: (1) the confection of A mixture: naphthenic acid is added with methanol and amine water, stirred for 10 to 20 minutes and sheared by a high-speed shearing machine for 10 minutes so as to obtain the brownish red liquid A mixture; (2) the confection of B mixture: acetone, 8- hydroxyquinoline, positive ethane, polyethylene menthanone, isooctyl ester nitrate and ethanol amine are directly mixed and added with an appropriate amount of diesel or coal oil as the auxiliary agent, thus obtaining the B mixture after even stirring; (3) the confection of C mixture: ferrocene, polyisobutylene and polyethylene-ester acid ethane are directly mixed and added with an appropriate amount of diesel or coal oil as the auxiliary agent, thus obtaining the C mixture after even stirring; (4) the A mixture is added with water and fully stirred, then the B mixture, the diesel and the C mixture are fully stirred after ultrasonic grinding and oil shearing by the high-speed shearing machine for more than ten minutes and finally the confection is completed after several minutes of oil shearing by the high-speed shearing machine. The synthesized methanol diesel prepared by the process has the beneficial technical effects of energy saving, environmental protection, no corrosion, wide application range, stable quality, simple production, etc., which is worth promoting.

A process for conversion of syngas to liquid products that serve as surface acting agents uses the gas stream at a relatively low pressure to eliminate the use of a compressor. The process uses a liquid stream as the primary energy input to a gas injector that intensely mixes gas and the liquid with reduced compression costs while the presence of the liquid product maintains the gas-liquid dispersion as it flows downward to build a static pressure head. The process lowers the required gas pressure by adjusting the elevation of the gas injector such that a conduit receives the gas-liquid dispersion from the outlet of the injector and confines it as it travels downward to enter the bottom of a column of liquid. The liquid product provides a surface acting agent that prolongs the creation and duration of microbubbles in the gas-liquid dispersion.

Separator and phase-split conveying method for eliminating plug flow on serious segments by utilizing same. The separator includes housing, collecting pipe and escape pipe connecting to the housing. The housing sets liquid level sensor and pressure sensor and has rising pipe which extends to the bottom of the housing. The extending part of the rising pipe sets the liquid phase pump connecting to the rising pipe by valve. The control valve is installed on the gas rising pipe closed the housing outlet. The inventive separator is installed at the connection section of the gas-liquid mixed transportation pipe and rising pipe and regulates the opening size of the control valve by controlling the liquid level signal and pressure signal to stabilize the liquid level and pressure. The liquid enters into rising pipe after the separation of the gas-liquid in the separator. The gas enters into the rising pipe through control valve and escape pipe. The liquid is mixed in the rising pipe and flows to the shore platform. The invention accurately controls the gas-liquid flow and eliminates the plug flow on serious segments.

A water treatment system including a pair of water treatment tanks, each tank defining a flow path extending from a tank inlet to a tank outlet and containing a water treatment material disposed along the flow path for treating water as it travels from the inlet to the outlet. A system controller controls which of the tanks is on-line and which of the tanks is off-line and controls the regeneration of an exhausted tank. A multi-stage, spring-loaded control valve assembly controls the communication of fluid to a regeneration control turbine and includes a piston head and a relatively movable seat-carrying stem. A spring urges the stem away from the piston head such that initial movement of the head compresses the spring but does not produce movement in the seat. Sufficient movement of the piston head produces movement in the seat, thereby causing the seat to open pressure.
