Pumping And Flow Control In Systems Including Microfluidic Systems

View page
US Patent:
8557570, Oct 15, 2013
Filed:
Nov 6, 2007
Appl. No.:
12/312348
Inventors:
Hemantkumar R. Sahoo - Houston TX, US
Klavs F. Jensen - Lexington MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
C12M 1/00
C12M 3/00
US Classification:
4352891, 422500, 137 14
Abstract:
The present invention generally relates to devices and methods for affecting the flow rate of fluid using pressure. The invention generally provides for controlled application of pressure to flowing fluids to control pressure and flow rates of those fluids, independent of location of the fluids relative to various devices. For example, in a series of devices, each connected to another via a conduit, pressure control units can be provided between devices to raise or lower pressure and/or flow rate of fluid flowing from one device to the next. In this way, a series of interconnected devices can be arranged such that inlet fluid pressure or flow rate of any individual device can be set independently of every other device.

US Patent:
20090282978, Nov 19, 2009
Filed:
Jul 5, 2006
Appl. No.:
11/988326
Inventors:
Klavs F. Jensen - Lexington MA, US
Jason G. Kralj - Washington DC, US
Hemantkumar R. Sahoo - Cambridge MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
B01D 19/00
B01D 53/02
B23P 11/00
US Classification:
95241, 96101, 29428
Abstract:
One aspect of the invention relates to fluid-phase separators and devices containing them. Another aspect of the invention relates to the use of said fluid-phase separators and devices containing them for separating individual phases from gas-liquid and liquid-liquid two-phase mixtures for a range of flow regimes. The present invention also relates to methods of making said fluid-phase separators and devices containing them.

US Patent:
20100122899, May 20, 2010
Filed:
Nov 13, 2009
Appl. No.:
12/617984
Inventors:
Ryan L. Hartman - Arlington MA, US
Hemantkumar R. Sahoo - Houston TX, US
Klavs F. Jensen - Lexington MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
B01D 3/00
B01D 11/00
B01D 17/00
B81B 7/00
B01D 19/00
B01D 47/00
US Classification:
203 28, 210634, 210638, 203 99, 203 71, 210775, 210799, 95227, 21074801
Abstract:
The present invention generally relates to the small-scale separation of a mixture of two or more components with different boiling points into enriched fractions. In some embodiments, a first and second fluid (e.g., a liquid and a gas, a liquid and a liquid, etc.) are passed through a channel. The first fluid may comprise at least two components, each with a unique boiling point. Upon contacting the first and second fluids within the channel, at least a portion of the most volatile of the components in the first fluid (i.e., the component with the lowest boiling point) may be transferred from the first fluid to the second fluid. In some instances, the transfer of the volatile component(s) from the first fluid to the second fluid may be expedited by heating, in some cases above the boiling point(s) of the component(s) to be transferred from the first fluid to the second fluid. Contact between the first and second fluids may be maintained, for example, via segmented flow, bubbling flow, etc. In some instances, separation between the first and second fluids may be maintained in a channel that is essentially free of interior microchannel surface irregularities.

Advanced Nmr Analysis Of Porosity And Other Properties In Core Samples Using Hydraulic Fluid Exchange

US Patent:
20200363352, Nov 19, 2020
Filed:
Mar 19, 2020
Appl. No.:
16/823948
Inventors:
- Spring TX, US
Pavel Kortunov - Flemington NJ, US
Harry W. Deckman - Clinton NJ, US
Shreerang S. Chhatre - The Woodlands TX, US
Hemantkumar R. Sahoo - Spring TX, US
Antonio S. Buono - Spring TX, US
International Classification:
G01N 24/08
G01R 33/44
Abstract:
A method for determining the porosity of a core sample can include: saturating a core sample with a nuclear magnetic resonance (NMR) saturation fluid, wherein the core sample has a permeability of 100 milliDarcy (mD) or less, to achieve a saturated core sample; taking a NMR measurement of fluids in the saturated core sample; determining a porosity of the core sample based on a correlation between the NMR measurement and a NMR signal to fluid volume calibration.

G01V 3/14
Abstract:
A method determining a volume of a pore type of a core sample can include: determining a porosity of a core sample, wherein the core sample has a permeability of 100 milliDarcy (mD) or less; saturating the core sample with a nuclear magnetic resonance (NMR) saturation fluid to achieve a saturated core sample; taking a NMR measurement of fluids in the saturated core sample; and deriving a volume for a pore type based on the porosity based on a correlation between the NMR measurement and a NMR signal to fluid volume calibration, wherein the pore type is selected from the group consisting of a nanopore, a micropore, a macropore, and any combination thereof
