Embodiment Construction

[0014]Referring now to FIG. 1, shown is a schematic representation of a conventional thermal oil operation, globally denoted by numeral 10. A source of natural gas 12 fuels the steam generator(s) 14 to generate steam 16 introduced into the hydrocarbon formation 18. Production fluids 20 (natural gas, water, viscous hydrocarbon material) are recovered and exposed to several treatment unit operations, generically referenced by numeral 22. Saleable heavy oil and bitumen is removed at 24 while produced water 26 is treated at 28 with at least a portion recycled as feed water 30 for use in generator(s) 14. Blowdown 32 is removed and make up water 34 added as required.

[0015]It is now trite that the cost of using natural gas to generate steam for hydrocarbon value recovery is unattractive from an economic point of view and inherently wasteful in view of the burgeoning activity and developments in alternate fuel synthesis. To this end, FIG. 2 is illustrative of a more pragmatic solution to th...

Abstract

A method for augmenting the heat enthalpy of an emulsified alternate fuel. An atomizing medium containing produced solution gas is used to atomize the emulsified fuel and add to the heat content of the emulsified fuel enhancing combustion. Alternate embodiments include the use of other gaseous hydrocarbon material as the atomizing medium either utilized alone or mixed with air or steam.

Description

FIELD OF THE INVENTION[0001]The present invention relates to augmenting the heat enthalpy of an emulsified alternate fuel and more particularly, the present invention relates to employing produced solution gas or other gaseous hydrocarbon products as an atomizing medium and a method of using such a fuel in the recovery of hydrocarbon.BACKGROUND OF THE INVENTION[0002]Typically, liquid fuels require some kind of atomization at the burner tip to facilitate mixing of the hydrocarbon liquid with combustion air, allowing combustion to occur. Atomization is normally achieved by combining the hydrocarbon stream with a separate stream of atomizing medium, this medium typically being low pressure steam or low pressure air. The atomizing medium assists in forcing the hydrocarbon stream through the atomizing nozzle, resulting in formation of small droplets. These droplets are brought into contact with combustion air within the combustion chamber, and provide mixing of the hydrocarbon with the c...
