Definitions
- the present invention relates to a fluid composition.
- the present invention relates to a fluid composition for use in pressurized container, such as an aerosol.
- gas bags are used as plugs in drill or bore holes in order to provide support for the surrounding rock and reduce the likelihood of rock fall.
- Conventional gas bags consist of a bag made from a resilient material (such as plastic) that is inflated by a gas produced during a chemical reaction that takes place in the bag, such as that of a mixture of an acid and a soda.
- a gas produced during a chemical reaction that takes place in the bag such as that of a mixture of an acid and a soda.
- these bags have the drawback of a high failure rate, for instance due to pre-inflation caused by a mixing of the reactants inside the bag during manufacture, storage, transportation and handling.
- the invention resides broadly in a fluid composition
- a fluid composition comprising a hydrocarbon gas or hydrocarbon gas blend, a carrier and an emulsifier.
- the hydrocarbon gas may comprise butane or propane.
- a blend of butane and propane such as Liquid Petroleum Gas or LPG
- LPG Liquid Petroleum Gas
- the carrier may be of any suitable form.
- the carrier is suitable for the hydrocarbon gas or hydrocarbon blend to be dissolved or dispersed in the carrier.
- the carrier comprises water or a suitable dilute aqueous solution. Any suitable type of emulsifier may be used in the fluid composition of the present invention.
- the emulsifier used in the fluid composition is not critical provided at the emulsifier assists in ensuring the fluid composition is a substantially homogeneous mixture.
- the emulsifier may have surfactant properties.
- a surfactant may also be added to the fluid composition.
- a skilled addressee will understand that any suitable surfactant may be used.
- the fluid composition may comprise any suitable ratio of components.
- the hydrocarbon gas or hydrocarbon gas blend and carrier may together comprise up to about 99.9% of the fluid composition, while it is envisaged that the emulsifier may be present in quantities of up to about 10% of the fluid composition.
- the ratio of hydrocarbon gas or hydrocarbon gas blend to carrier in the fluid composition is not critical and may vary depending on the type of hydrocarbon gas or hydrocarbon gas blend and carrier used in the fluid composition. However, it will be understood that the fluid composition must comprise a sufficient quantity of each component in order for the fluid composition to form a substantially homogeneous mixture.
- the fluid composition may further comprise alcohol. Alcohol may be present in the fluid composition for a number of reasons, including reducing pressure in the container in which the fluid composition is stored and transported. Any suitable alcohol (or blend of alcohols) may be present. In a preferred embodiment of the invention, the alcohol may be ethanol.
- the alcohol may assist in dissolving the hydrocarbon gas or hydrocarbon gas blend in the carrier.
- the presence of alcohol in the fluid composition may assist in the creation of a foam when the fluid composition is dispensed from a dispenser.
- the addition of alcohol may assist in reducing the flammability of the fluid composition.
- the alcohol comprises no more than about 10% of the fluid composition.
- alternative substances to alcohol may be used. For instance, in one embodiment, acetone may be used instead of alcohol.
- the fluid composition is substantially nonflammable.
- the invention resides broadly in an aerosol dispenser containing a fluid composition comprising a hydrocarbon gas or hydrocarbon gas blend, a carrier and art emulsifier.
- a hydrocarbon gas or hydrocarbon gas blend may be used.
- the hydrocarbon gas may comprise butane or propane.
- a blend of butane and propane such as Liquid Petroleum Gas or LPG
- LPG Liquid Petroleum Gas
- the carrier may be of any suitable form.
- the carrier is suitable for the hydrocarbon gas or hydrocarbon blend to be dissolved or dispersed in the carrier.
- the carrier comprises water or a suitable dilute aqueous solution.
- the dilute aqueous solution may contain any suitable material.
- the aqueous solution my contain one or more compounds or the like.
- the aqueous solution may one or more carbomers. Any suitable carbomer may be used. .
- the carbomer may include a cross-linked polyacrylic acid polymer such as Ultrez 10 manufactured by the Lubrizol Corporation.
- the carbomer may be present in any suitable quantity in the aqueous solution. In some embodiments, the carbomer may be present in an amount of no more than 10%. More preferably, the carbomer may be present in an amount of no more than 5%. Still more preferably, the carbomer may be present in an amount of no more than 1%; In one particular embodiment, the carbomer is present in an amount of about 0.5% of the aqueous solution.
- the aqueous solution may include further compounds in addition to, or instead of, the carbomer.
- Such compounds may include coco betaine (such as that manufactured under the trade name Empigen BB) or coconut diethanolamide (such as that manufactured under the trade name Empilan FD).
- the coco betaine or coconut diethanolamide is present in an amount of less than 50% of the aqueous solution. More preferably, the coco betaine or coconut diethanolamide is present in an amount of less than 25% of the aqueous solution. Most preferably, the coco betaine or coconut diethanolamide is present in an amount of about 10% of the aqueous solution.
- the aqueous solution may include about 0.5% carbomer and about 10% coconut diethanolamide.
- the use of these components will result in a fluid composition that requires mechanical agitation.
- the container or vessel in which the fluid composition is provided may require agitation (such as by shaking the container) after the container is gassed and/or prior to dispensing the contents of the container.
- coco betaine or coconut diethanolamide could be used in the fluid composition
- coconut diethanolamide is used in preference to coco betaine. This is because it has been found that fluid compositions using coco betaine produce a relatively short-lasting foam and a fast burning (but riot explosive) foam. On the other hand, the fluid composition using coco betaine does not require any mechanical agitation.
- emulsifiers While some specific emulsifiers have been described above (carbomer, coconut diethanolamide and coco betaine), it is envisaged that any suitable type of emulsifier may be used in the fluid composition of the present invention.
- the precise nature of the emulsifier used in the fluid composition is not critical provided at the emulsifier assists in. ensuring the fluid composition is a substantially homogeneous mixture.
- the emulsifier may have surfactant properties.
- a surfactant may also be added to the fluid composition.
- a skilled addressee will understand that any suitable surfactant may be used.
- the fluid composition may comprise any suitable ratio of components.
- the hydrocarbon gas or hydrocarbon gas blend and carrier may together comprise up to about 99.9% of the fluid composition, while it is envisaged that the emulsifier may be present in quantities of up to about 25% of the fluid composition, and preferably up to about 10.5% of the fluid composition.
- the ratio of hydrocarbon gas or hydrocarbon gas blend to carrier in the fluid composition is not critical and may vary depending on the type of hydrocarbon gas or hydrocarbon gas blend and carrier used in the fluid composition. However, it will be understood that the fluid composition must comprise a sufficient quantity of each component in order for the fluid composition to form a substantially homogeneous mixture.
- the fluid composition may further comprise alcohol. Any suitable alcohol (or blend of alcohols) may be present.
- the alcohol may be ethanol.
- the alcohol may assist in dissolving the hydrocarbon gas or hydrocarbon gas blend in the carrier.
- the presence of alcohol in the fluid composition may assist in the creation of a foam when the fluid composition is dispensed from a dispenser.
- the addition of alcohol may assist in reducing the flammability of the fluid composition, and may reduce the pressure of the fluid composition in the container in which it is stored and transported.
- the alcohol comprises no more than about 10% of the fluid composition.
- the aerosol dispenser may further comprise a propellant.
- a propellant Any suitable propellant may be used, such as, but not limited to, a hydrocarbon or combination of hydrocarbons, air, nitrogen or the like, or any combination thereof, or indeed any other propellant known to a person skilled in the art.
- the propellant may be added to the fluid composition prior to the fluid composition being added to the aerosol dispenser.
- the difference in pressure between the interior of the aerosol dispenser and the ambient environment may be sufficient to propel the fluid composition out of the aerosol dispenser on actuation of the aerosol dispenser without requiring the addition of a propellant.
- the fluid composition may be provided in any suitable aerosol dispenser.
- the aerosol dispenser is adapted to house a pressurized fluid.
- the aerosol dispenser may be fabricated from metal, plastic or any suitable polymer blend or the like, or any combination thereof.
- the aerosol dispenser is an aerosol can.
- the ratio of the components in the fluid composition is such that, as the fluid composition is dispensed from the aerosol dispenser, the fluid composition forms a foam.
- the invention resides broadly in a system for plugging a drill hole or bore hole, the system comprising:
- an aerosol dispenser located within the inflatable container and containing an fluid composition comprising a hydrocarbon gas or hydrocarbon gas blend, a carrier and an emulsifier,
- the aerosol dispenser dispenses the fluid composition to ' cause inflation of the inflatable container.
- the inflatable container is fabricated from a resilient, substantially leak-proof material.
- the inflatable container may be fabricated from plastic, such as, but not limited to HDPE.
- the fluid composition may further comprise alcohol. Any suitable alcohol (or blend of alcohols) may be present.
- the alcohol may be ethanol.
- the invention resides broadly in a method of plugging a drill hole or bole hole comprising the steps of:
- an inflatable container including an aerosol dispenser containing a fluid composition comprising a hydrocarbon gas or hydrocarbon gas blend, a carrier and an emulsifier;
- the fluid composition may further comprise alcohol. Any suitable alcohol (or blend of alcohols) may be present.
