| 20080202589 | Fluid-Flow System, Device and Method - Methods, devices, and systems are disclosed for combining fluids of different pressures and flow rates in, for example, gas gathering systems, gas wells, and other areas in which independently powered compressors are not desired. Methods, devices, and systems for turning a shaft are also provided, as are methods, devices, and systems for dropping pressure in a gas line. | 08-28-2008 |
| 20080264489 | Method and a Device for Handling a Liquid - The present invention relates to a method and a column to handle foaming liquids or high viscous liquids and prevent flooding in liquid-gas mass transfer operations. Said operation is carried out by using higher or equal pressure at the liquid inlet than at the liquid outlet in said column. Said column comprises a single shell ( | 10-30-2008 |
| 20080314453 | FUEL SUPPLY SYSTEMS - A fuel supply system includes a pressure regulator ( | 12-25-2008 |
| 20090090415 | CHEMICAL DELIVERY SYSTEM - An expandable chemical delivery system sharing a common bulk fluid inlet and bulk fluid flow path to direct a bulk fluid through one or more selected chemical eductors. Each chemical eductor is slidably insertable into an eductor port on the manifold body such that rotation of the chemical eductor is not required for installation. After installation, the orientation of the chemical eductor can be rotatably adjusted so as to avoid interference with adjacent chemical eductors. Delivery of a bulk fluid to each chemical eductor is controlled via a corresponding valve assembly that selectively allows or blocks flow of the bulk fluid form the bulk fluid flow path to the corresponding chemical eductor. The manifold body can include a plurality of individual manifold bodies approximated with a coupling system to define the bulk fluid flow path. Alternatively, the manifold body can comprise a single fabricated body for high pressure operation. | 04-09-2009 |

| 20110048544 | SLUG MITIGATION - A method and apparatus for mitigating slug formation in a multiphase fluid stream that is flowing through a conduit wherein the conduit comprises a first portion and a second portion which is upwardly inclined to the first portion and wherein the multiphase fluid stream comprises a gaseous phase and a liquid phase, the method comprising the steps of: (a) determining the pressure in the conduit upstream of a slugging zone; (b) determining the pressure in the conduit downstream of the slugging zone; (c) determining the actual pressure difference across the slugging zone by subtracting the downstream pressure from step (b) from the upstream pressure from step (a); (d) determining the error between a target pressure difference and the actual pressure difference; (e) producing a signal comprising a first component which is proportional to the error and a second component which is proportional to the rate of change of the error over time; and (f) using the signal produced in step (e) to control the position of an adjustable choke valve located downstream of the slugging zone so as to stabilise variations arising in the actual pressure difference over time. | 03-03-2011 |
| 20140196794 | SYSTEM AND PROCESS FOR SUPPLYING A CHEMICAL AGENT TO A PROCESS FLUID - There is provided a process for controllably supplying a chemical agent to a flowing process fluid for effecting generation of treated flowing fluid comprising a chemical agent-derived fluid component material, wherein the chemical agent-derived fluid component material is derived from the chemical agent. The controllably supplying comprises: while discharging a chemical agent from a chemical agent supply system, modulating distribution of the chemical agent that is being discharged, between at least a flowing process fluid and a fluid bypass, with a chemical agent supply modulation system, in accordance with a system operating cycle, wherein the system operating cycle includes a single system supply mode and a single system bypass mode, and wherein the system bypass mode follows the system supply mode. | 07-17-2014 |
| 20140326322 | METHOD FOR DISPENSING A FLUID MEDIUM - The invention relates to a method for metering a fluid medium by means of a metering device in the form of a piston pump having a cylinder (Z) and a movable piston ( | 11-06-2014 |
| 20150107679 | METHOD OF, AND APPARATUS FOR, PROVIDING A GAS MIXTURE - There is provided a gas mixer arrangement comprising a first gas source for supplying a first gas; a second gas source for supplying a second gas different from said first gas; a first valve for regulating the flow of the first gas; a second valve for regulating the flow of the second gas; a mixer located downstream of the first and second valves and arranged, in use, to mix the first and second gases to provide a mixed gas; a meter arranged to measure the average molecular weight of the mixed gas, comprising a high-frequency planar piezoelectric crystal oscillator in contact with the mixed gas and a sensor operable to determine atmospheric pressure; and a controller operable, in response to the measured average molecular weight of said mixed gas, to control at least one of said first and second valves in order to control the relative proportion of the first and second gases in said mixed gas. | 04-23-2015 |
| 20160040628 | ELECTRONIC CONTROLLED FUEL ENRICHMENT SYSTEM - An apparatus for delivering a fuel-air mixture to an engine is provided. The apparatus includes: a carburetor having one or more passages and one or more chambers, wherein at least some of the passages and chambers are in communication with one another, and a fluid pump communicated with the carburetor and pumping fluid into or out of the carburetor to influence an fuel-to-air ratio of a fuel and air mixture delivered from the carburetor. | 02-11-2016 |
| 20160085246 | PREPARATION OF HIGH PRESSURE BF3/H2 MIXTURES - Methods are described for filling gas mixture supply vessels with constituent gases to achieve precision compositions of the gas mixture, wherein the gas mixture comprises at least two constituent gases.
