Atomized Liquid Injection (ALI) is a very effective method for injecting liquids and slurries uniformly within all types of geology. In addition, the injection radius of influence is considerably greater than what is achievable using conventional hydraulic injection. ALI relies upon the premise that it is more effective to inject gases or “aerosols” into the subsurface than it is to inject a non-compressible liquid into the subsurface.
When adapting our systems for liquid injection, the liquid is introduced into a high flow, high-velocity gas stream. The liquid is thereby atomized into an aerosol with characteristics more closely resembling that of a gas instead of a non-compressible fluid.
The pictures below demonstrate how liquid becomes atomized and is readily injectable into the subsurface. Liquids, including bio-innoculum, nutrient solutions, redox compounds, hydrogen peroxide, acids and liquid oxidants, such as potassium permanganate (KMnO4) and sodium persulfate can be atomized and delivered into the subsurface. Even low viscosity fluids such as vegetable oils and molasses can be atomized in our process.
When applied in low permeability formations, the atomized liquid is introduced in conjunction with the Pneumatic Fracturing while the fracture network is dilated. This procedure ensures effective dispersion throughout the fracture network. When applied in higher permeability material that is not fracturable, the atomized material is well mixed within the soil matrix.
The photographs below show a comparison of a conventional hydraulic injection versus liquid atomized injection. It is important to note that the liquid feed rate remained constant in both processes.
