ClearWELL uses radio transmissions to supply energy into a system prior to a supersaturation event which encourages precipitation in suspension.
Why Does the Precipitate Normally Form a Deposit?
• When a material precipitates, not only is a new phase formed, a surface between the old and new phases must be formed. It takes energy to create a new surface, and this energy is not accounted for in the bulk description of solubility
• The energy required to form the new surface is proportional to the surface area being formed. A new phase will develop on an existing surface simply because less new surface is required which therefore requires less energy.
• In a pipe or oil well the existing surface is provided by the pipe, the valves and anything else that is internal to the pipe
• Under normal conditions therefore nucleation occurs at solid-liquid interfaces because less energy is required.
• ClearWELL™ operates by inducing homogeneous nucleation by introducing Kinetic energy into the system so that crystallites form in suspension
• These small crystallites serve as nucleation sites for the precipitation of the rest of the solution
• The large surface area provided by the millions of small crystallites dominates the thermodynamic evolution of the system
Principles of ClearWELL™ are therefore
• Use of a physical device to create millions of nucleation sites and deplete the saturation condition
• Keeps microcrystals suspended by fluid flow
• An electrical signal propagates through the entire pipe run.
• There is no focus on a specific zone,
• Wherever saturation occurs, ClearWELL™ works
