Filed:

Jan 12, 2011

Appl. No.:

13/005098

Inventors:

Richard HUNTINGTON - Oak Hill VA, US

Assignee:

EXXONMOBIL RESEARCH AND ENGINEERING COMPANY - Annandale NJ

International Classification:

F02C 3/20

US Classification:

60780, 60 3912

Abstract:

Systems and methods for improving the operation of a combustion device using a low heating value fuel that includes providing a supply of a low heating value fuel, introducing an oxidizing agent that includes an enriched oxygen source into the low heating value fuel, and directing the low heating value fuel and the oxidizing agent to the combustion device, whereby the operation of the combustion device is improved.

Jeffrey W. Frederick - Centreville VA, US
Robert F. Tammera - Warrenton VA, US
Richard A. Huntington - Houston TX, US

International Classification:

B01D 53/02

US Classification:

96110

Abstract:

An adsorber with minimal dead volume especially suited to reverse-flow applications comprises: a) an adsorber body; b) a first head engaged with said adsorber body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body. The adsorber is especially suited for use in a process for swing adsorption separation processes.

Abstract:

Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes a gas turbine system configured to stoichiometrically combust a compressed oxidant derived from enriched air and a fuel in the presence of a compressed recycle exhaust gas and expand the discharge in an expander to generate a recycle exhaust stream and drive a main compressor. A boost compressor receives and increases the pressure of the recycle exhaust stream and prior to being compressed in a compressor configured to generate the compressed recycle exhaust gas. To promote the stoichiometric combustion of the fuel and increase the COcontent in the recycle exhaust gas, the enriched air can have an increased oxygen concentration.
