5 results about "Aerosol Foam" patented technology

This invention relates to the field of carbon storage and utilization technology, specifically disclosing a method for increasing carbon dioxide storage capacity using an aerosolized foaming agent. The invention employs an aerosolized foaming agent, which not only utilizes formation water for in-situ foaming to increase carbon storage space but also achieves dynamic stability after foam collapse. In-situ foaming is achieved around the wellbore through alternating injection of a pre-placed aerosolized foaming agent slug and a post-placed CO2 slug. By setting a real-time injection pressure feedback mechanism to dynamically adjust the injection method, early carbon dioxide breakthrough and loss are reduced, significantly improving storage efficiency and effectively enhancing the carbon dioxide storage effect.

An aerosol foam dispenser having a container configured to contain a composition and a propellant; a valve assembly in fluid communication with the container; and an actuator assembly. The actuator assembly includes a supply channel in fluid communication with the valve assembly; a nozzle in fluid communication with the supply channel and configured to atomize the composition; an expansion chamber; a porous barrier extending in a direction substantially parallel to an outer end surface of the nozzle; and an actuator in operative communication with the valve assembly. The expansion chamber includes a sidewall having an air vent extending therethrough.

The present invention is directed to an aerosol foam composition comprising roflumilast, an emulsifier blend containing cetearyl alcohol, dicetyl phosphate, and ceteareth-10 phosphate and a hydrocarbon propellant. The aerosol foam composition is preferably an oil in water emulsion. The propellant is a mixture of liquefied hydrocarbon gases preferably a propane / isobutane / butane blend. The hydrocarbon propellant results in an aerosol foam which is stable, has consistent physical properties, excellent aesthetics, and no discernable degradation after long term or accelerated storage conditions.
